Inpatient peritoneal dialysis catheters placed across the United States during a 3-year period: Lessons learned from 15,000 patients.

BACKGROUND: Peritoneal dialysis is a popular option for patients with end-stage renal disease. A recent presidential executive order has incentivized in-home end-stage renal disease treatments, leading to an increase in peritoneal dialysis use. Guidelines exist for creating and maintaining peritoneal dialysis access without addressing the optimal technique. This study evaluates nationwide peritoneal dialysis catheter placement practices and their long-term outcomes. METHODS: Retrospective cohort analysis of Nationwide Readmission Database from 2017 to 2019. Patients with end-stage renal disease undergoing inpatient peritoneal dialysis catheter placement were included. Six-month readmissions, mortality, and peritoneal dialysis catheter-specific outcome measures were assessed among survivors of admission, including catheter leakage, mechanical breakdown, displacement, revision or replacement, removal, exit site infections, intra-abdominal abscess, and sepsis. Binary logistic regression analyses were performed. RESULTS: In the study, 14,863 patients with inpatient peritoneal dialysis catheter insertions were identified, of which 7,096 were analyzed (4,150 [59%] laparoscopic, 1,781 [25%] fluoroscopic, 1,165 [16%] open), 847 (12%) had major complications, 931 (13%) were readmitted, and 102 (1.4%) died within 6 months. Univariate analyses demonstrated that laparoscopy had higher mechanical complications, exit-site infections, catheter revision, and removal within 6 months, and fluoroscopy had higher sepsis and mortality. Multivariate analyses showed fluoroscopy was associated with intraabdominal abscess (adjusted odds ratio, 2.36; P = .025), laparoscopy with exit-site infections (adjusted odds ratio, 0.49; P = .005), and open surgery with catheter displacement (adjust odds ratio, 2.95; P = .021). CONCLUSION: This is the first large-scale study on inpatient peritoneal dialysis catheter placement outcomes in the United States. Fluoroscopic and open surgical placements are routinely performed, but laparoscopy remains the mainstay with fewer exit-site infections. Overall, peritoneal dialysis is a safe option, with 1 in 9 patients having an infectious or mechanical complication within 6 months. Furthermore, large-scale prospective studies are warranted to identify the optimal placement technique.

Circumstances and implications of conversion from minimally invasive to open liver resection: a multi-center analysis from the AMILES registry.

BACKGROUND: Minimally invasive approaches to liver resection (MILR) are associated with favorable outcomes. The aim of this study was to determine the implications of conversion to an open procedure on perioperative outcomes. METHODS: Patients who underwent MILR at 10 North American institutions were identified from the Americas Minimally Invasive Liver Resection (AMILES) database. Outcomes of patients who required conversion were compared to those who did not. Additionally, outcomes after conversion due to unfavorable findings (poor visualization/access, lack of progress, disease extent) versus intraoperative events (bleeding, injury, cardiopulmonary instability) were compared. RESULTS: Of 1675 patients who underwent MILR, 102 (6.1%) required conversion. Conversion rate ranged from 4.4% for left lateral sectionectomy to 10% for right hepatectomy. The primary reason for conversion was unfavorable findings in 67 patients (66%) and intraoperative adverse events in 35 patients (34%). By multivariable analysis, major resection, cirrhosis, prior liver surgery, and tumor proximity to major vessels were identified as risk factors for conversion (p < 0.05). Patients who required conversion had higher blood loss, transfusion requirements, operative time, and length of stay, (p < 0.05). They also had higher major complication rates (23% vs. 5.2%, p < 0.001) and 30-day mortality (8.8% vs. 1.3%, p < 0.001). When compared to those who required conversion due to unfavorable findings, patients who required conversion due to intraoperative adverse events had significantly higher major complication rates (43% vs. 14%, p = 0.012) and 30-day mortality (20% vs. 3.0%, p = 0.007). CONCLUSIONS: Conversion from MILR to open surgery is associated with increased perioperative morbidity and mortality. Conversion due to intraoperative adverse events is rare but associated with significantly higher complication and mortality rates, while conversion due to unfavorable findings is associated with similar outcomes as planned open resection. High-risk patients may benefit from early conversion in a controlled fashion if difficulties are encountered or anticipated.

Marginal Ulcer Following Completion Pancreatectomy Complicated by Portal Vein Erosion.

Marginal ulcers, defined as ulcers at the duodenojejunostomy or gastrojejunostomy, are a known late-onset complication of pancreaticoduodenectomy (PD) and total pancreatectomy (TP) with mean incidence ranging from 5.4% to 36% per the literature. These ulcers carry a risk of complications including hemorrhage or perforation which can result in significant mortality. Marginal ulcers from PD and TP causing portal vein erosion are extremely rare and given the high incidence of mortality, it is important to have a multimodal approach to the treatment with awareness that early operative management should be considered if other modalities fail. We discuss the case of a 57-year-old female with history of pancreatic tail intraductal papillary mucinous neoplasm (IPMN) status post distal pancreatectomy/splenectomy and subsequent completion pancreatectomy for pancreatic head IPMN who presented with acute gastrointestinal bleed. The patient was successfully managed operatively with primary repair of the marginal ulcer after multiple failed endoscopic attempts.

Microfluidic sperm sorting improves ICSI outcomes in patients with increased values of Double-Strand Breaks in sperm DNA.

BACKGROUND: Delays in embryo kinetics, implantation failures in ICSI treatments and recurrent miscarriages have been associated with high values of Double-Strand Breaks (DSB) in sperm DNA. While conventional methods for semen preparation have been shown to be inefficient reducing DSB values, Microfluidic Sperm Sorting (MSS) devices are promising tools to reduce this damage. OBJECTIVE: To study the clinical utility of an MSS device in ICSI treatments when the male partner presents increased DSB values, as compared to the use of conventional methods based on sperm motility. METHODS: This retrospective cohort study included 28 infertile couples undergoing ICSI treatments. Only couples where the male partner presented increased values of DSB were included. DSB values were evaluated in semen samples by the Neutral Comet assay. Couples performed a first ICSI cycle using conventional methods for semen preparation (Density Gradients and Swim-up) and a second ICSI cycle using the ZyMot™ICSI (formerly named FertileChip®) microfluidic device. Embryology and clinical outcomes were compared between ICSI cycles. RESULTS: Semen parameters and the number of obtained and fertilized oocytes did not show differences between ICSI rounds. Clinical outcomes were statistically better when MSS was used: the biochemical pregnancy rate increased 28.31%; the clinical pregnancy rate increased 35.56% and the number of live births increased 35.29%, as compared to the first ICSI cycle in this group of patients. CONCLUSIONS: The ZyMot™ICSI microfluidic device improved the reproductive outcomes in couples where the male partner presented increased DSB values, when compared to the use of conventional semen preparation techniques.

Elevated serum uric acid is a facilitating mechanism for insulin resistance mediated accumulation of visceral adipose tissue.

OBJECTIVE: Serum uric acid (SUA) has been associated with cardiometabolic conditions such as insulin resistance (IR) and visceral adipose tissue (VAT) accumulation. Here, we aimed to clarify a unifying mechanism linking elevated SUA to IR and VAT. METHODS: We conducted analyses in 226 subjects from the UIEM cohort with both euglycemic hyperinsulinemic clamp (EHC) and dual X-ray absorptiometry (DXA) measurements for IR and VAT accumulation and explored the role of SUA and adiponectin by developing a network of causal mediation analyses to assess their impact on IR and VAT. These models were then translated to two population-based cohorts comprising 6337 subjects from NHANES 2003-2004 and 2011-2012 cycles in the US and ENSANUT Medio Camino 2016 in Mexico, using HOMA2IR and adipoIR as indicators of peripheral and adipose tissue IR, and METS-VF as a surrogate for VAT accumulation. RESULTS: SUA has a mediating role inside a bidirectional relationship between IR and visceral obesity, which was similar using either gold standard measurements or surrogate measures for IR and VAT. Furthermore, adiponectin acts as a linking mediator between elevated SUA and both peripheral IR and VAT accumulation. The proportion of the mechanism for IR-mediated (in either peripheral or adipose tissue) VAT accumulation was greater, compared to VAT-mediated IR accumulation (10.53% [9.23%-12.00%] to 5.44% [3.78%-7.00%]). Normal-range SUA levels can be used to rule-out underlying cardio-metabolic abnormalities in both men and women. CONCLUSIONS: Elevated SUA acts as a mediator inside the bidirectional relationship between IR and VAT accumulation and these observations could be applicable at a phenotype scale.

Sperm selection during ICSI treatments reduces single- but not double-strand DNA break values compared to the semen sample.

PURPOSE: To detect a possible bias in sperm DNA fragmentation (SDF) testing when performed on semen samples or on those few spermatozoa selected for Intracytoplasmic Sperm Injection (ICSI) treatments. METHODS: A multimethodological analysis of Single- and Double-Strand DNA Breaks (SSB and DSB, respectively) was performed through the Neutral Comet, the Alkaline Comet, the Sperm Chromatin Dispersion (SCD) and the Terminal deoxynucleotidyl transferase dUTP Nick End Labelling (TUNEL) assays. SDF was evaluated in (i) semen samples from 23 infertile patients (not achieving pregnancy or suffering recurrent miscarriage); (ii) samples after a Swim-up and (iii) spermatozoa microselected for ICSI (ICSI-S). RESULTS: The analysis of 3217 ICSI-S revealed a significant reduction of SSB values compared to the Ejaculate and the Swim-up samples. On the contrary, DSB values were not reduced after any sperm selection method. The No-pregnancy group presented poorer semen parameters and higher SSB values. The Recurrent miscarriage group presented better semen parameters but also higher DSB values. CONCLUSION: The analysis of SDF on semen samples may not be fully representative of those few spermatozoa selected for ICSI. Since oxidative stress impairs sperm motility and causes SSB, selecting a motile sperm may intrinsically imply choosing a sperm not affected by this damage. DSB have an enzymatic origin which does not affect motility, making it difficult to select a sperm without this damage. Therefore, ICSI treatments could be effective in patients presenting high SSB values. Patients presenting high DSB values should expect bad ICSI results if this damage is not reduced through other specific methods.

[Índices para la evaluación de la resistencia a la insulina en individuos mexicanos sin diabetes].

OBJECTIVE: To evaluate the correlation between subrogate index for the evaluation of insulin resistance with the M value obtained with the euglycemic-hyperinsulinemic clamp as well as their sensitivity, specificity, and positive and negative predictive values. METHOD: The euglycemic-hyperinsulinemic clamp was performed in subjects having both normal fasting glucose and glycated hemoglobin concentrations. HOMA-IR, QUICKI, HOMA2%S, TyG, TyG*body mass index (BMI) and triglyceride/HDL indexes were calculated. Correlations coefficients were estimated between indexes results and the M-value adjusted by fat-free mass. Areas under the ROC curve were constructed to evaluate overall performance, sensitivity, specificity and predictive values of the subrogate indexes. RESULTS: 57 subjects, 68.4% women, with a mean age of 32.9 ± 11 years-old were included. The subrogate index with the best correlation with the M value was HOMA2%S (r = 0.428), HOMA-IR had the greatest area under the ROC curve (0.683; 95 % confidence interval: 0.503-0.864) and TyG*BMI the best sensitivity (98.2 %) and specificity (51.1 %). CONCLUSIONS: The surrogated indexes for the evaluation of insulin resistance show a significant correlation with the M value obtained with the gold standard. Additional studies are required to determine cut-off values in Mexican population.

OBJETIVO: Evaluar la correlación entre índices subrogados de resistencia a la insulina y el valor M obtenido mediante pinza euglucémica-hiperinsulinémica, así como su sensibilidad, especificidad y valores predictivos positivo y negativo, en mexicanos sin diabetes. MÉTODO: Se realizó una pinza euglucémica-hiperinsulinémica en individuos con glucosa en ayuno y hemoglobina glucosilada normales. Se estimaron los índices HOMA-IR, QUICKI, HOMA2%S, TyG, TyG*índice de masa corporal (IMC) y triglicéridos/colesterol ligado a lipoproteínas de alta densidad. Se estimaron coeficientes de correlación de Pearson entre los resultados y el valor M ajustado por masa libre de grasa. Se construyeron curvas ROC para evaluar su desempeño y se estimaron la sensibilidad, la especificidad y los valores predictivos de los índices. RESULTADOS: Se incluyeron 57 individuos, el 68.4 % mujeres, de 32.9 ± 11 años, con IMC de 26.5 ± 3.9 kg/m2. El índice subrogado con mejor correlación con el valor M fue HOMA2%S (r = 0.428), con la mayor área bajo la curva ROC (0.683; intervalo de confianza del 95 %: 0.503-0.864) HOMA-IR, y con mejor sensibilidad (92.8 %) y especificidad (51.1 %) TyG*IMC. CONCLUSIONES: Los índices subrogados para estimar la resistencia a la insulina muestran una correlación significativa con el valor M obtenido con el método de referencia. Se requieren más estudios para determinar puntos de corte en población mexicana.

ABSTRACT The purpose was to verify the level of health-related quality of life in a population-based sample of adults aged 20 years or more living in the city of Bauru, São Paulo, Brazil, and its association with the amount of reported morbidities. A population survey was conducted through a complex sampling in two stages, totaling 600 participants in the urban area of Bauru, São Paulo. To collect data, the following instruments were used: 1. Characterization of participants (demographic and socio-economic aspects, physical activity level and smoking habit); 2. reported morbidity through the following question: "Last year, did you receive a diagnosis of any illness from a doctor?; 3. Quality of Life, using the Medical Outcomes Study 36 - Item Short-Form Health Survey (SF-36) questionnaire. Descriptive and bivariate analyses were carried out using the Student's t-test and ANOVA. It was noted that 70.5% had at least one disease, and the most common morbidities reported were hypertension, osteoarthritis, depression, and diabetes. The association between the number of diseases, those who reported three or more diseases, and older age had worse HRQOL scores in all physical domains and limitations by social and emotional aspects. A greater number of comorbidities was associated with the lower scores of health-related quality of life.

Educação continuada em gerontologia para agentes comunitários de saúde / Continuing Education in gerontology for community health agent / Educación continua en gerontología para los agentes comunitarios de salud

Objetivo: avaliar o efeito de um Programa de Educação em Gerontologia desenvolvido à Agentes Comunitários de Saúde. Métodos: estudo de intervenção (comparação antes e depois) com participação de 111 agentes comunitários, com perda de 25 (22,5%), atuantes nas 12 unidades de saúde da família de um município do interior paulista, em 2012. Os dados foram coletados por meio de questionário sociodemográfico, instrumento de avaliação do contato dos agentes comunitários com idosos e questionário para avaliação de conhecimentos gerontológicos (Questionário Palmore-Neri-Cachioni). Foi desenvolvido um Programa de Educação em Gerontologia junto aos agentes comunitários, no período de 5 dias: encontros com duração de 90 minutos cada um, abordando temas relacionados à velhice e envelhecimento. Para análise dos dados, foi utilizado o programa SAS versão 9.2 para Windows. Resultados: prevaleceram entre os agentes os adultos jovens, do sexo feminino, casados, com ensino médio completo e inseridos na atividade há mais de dois anos e meio. A maioria dos agentes expôs sempre ter contato com idosos, cultivado em âmbito do trabalho e intrafamiliar e relatou experiência com a população dessa faixa etária, mais da metade referiu ter participado de educação gerontológica. O maior número de acertos ao questionário de avaliação sobre conhecimentos gerontológicos, aplicado antes, imediatamente após e depois de três meses ao desenvolvimento do Programa de Educação em Gerontologia, demonstrou melhor desempenho dos agentes na segunda e terceira aplicações desse instrumento realizadas após o programa, tornando evidente a importância de educação em gerontologia para esse público. Conclusão: promover educação em gerontologia para agentes comunitários de saúde é fundamental, pois providos de conhecimentos podem reforçar seu papel mediante a equipe de saúde e população, dentre ela, os idosos.

Objective: to evaluate the effect of an education program in gerontology for community health agents. Methods: this intervention study (before and after comparison) included 111 community agents, lossy 25 (22.5%), from 12 family health centers from city in the state of São Paulo in 2012. Data were collected through a sociodemographic questionnaire, to determine the formal and informal contact of the elderly group with the community health agents, as well as through a questionnaire that evaluated gerontological knowledge (Questionnaire Palmore-Neri-Cachioni). Moreover, an education program in gerontology was conducted for community agents, including 90-minute sessions over a 5-day period, which focused on topics related to old age and aging. Data analysis was performed using the SAS version 9.2 for Windows. Results: young adults, female sex, married status, high school education, and activity for more than two and a half years were common characteristics associated with community agents. Most of the agents were in contact with the elderly, to cultivate of work and within the family, and reported to have experience in dealing with this age group. Moreover, more than half of the community agents reported to have participated in gerontological education. The questionnaire assessing the knowledge on gerontology, which was applied before, immediately after, and three months after the education program in gerontology indicated better responses among the community health agents immediately after and three months after the program, thus suggesting that education in gerontology is important among these individuals. Conclusion: promoting education in gerontology among community health agents is essential, as the knowledge provided can strengthen the role of health care staff and the population in caring for the elderly.

Patterns of Weight Loss Response Following Gastric Bypass and Sleeve Gastrectomy.

BACKGROUND: Despite the health benefits of bariatric surgery (BS) extend beyond WL, better understanding of the WL response may help improve the outcomes of BS. In this context, we aimed to assess patterns within the variability of weight loss (WL) after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). METHODS: WL data from 658 subjects that underwent RYGB (n = 464) or SG (n = 194) as first BS were analyzed. Based on excess WL (EWL), subjects were categorized as good WL responders (EWL ≥ 50 % at nadir weight and throughout follow-up), primarily poor WL responders (1-PWL:EWL < 50 % at nadir weight and thereafter), and secondarily poor WL responders (2-PWL:EWL ≥ 50 % at nadir weight, but <50 % at last follow-up visit). Predictors associated with different WL outcomes were ascertained using regression analysis. RESULTS: Median follow-up was 55.7 months. Nadir EWL ranged 12.4-143.6 %; last follow-up visit EWL ranged -22.1-143.6 % and weight regain (WR) ranged 0-64.1 kg. Good WL was found in 75.7 of the cohort. 1-PWL response (4.7 %) was characterized by lesser WL but similar WR as compared to good WL and was associated with larger BMI and diabetes prior to surgery. 2-PWL response (19.6 %) was characterized by larger WR as compared to the other groups and was more common following SG. Lesser percentage of medical appointments kept was associated with 1-PWL and 2-PWL. CONCLUSION: Our data show the high inter-individual variability of the WL response at mid-term after RYGB and SG and that poor WL after BS could be illustrated by two different patterns, characterized either by sustained limited WL (1-PWL), or pronounced weight regain (2-PWL).

Chronic administration of nicotine enhances NMDA-activated currents in the prefrontal cortex and core part of the nucleus accumbens of rats.

Nicotine is an addictive substance of tobacco. It has been suggested that nicotine acts on glutamatergic (N-methyl-d-aspartate, NMDA) neurotransmission affecting dopamine release in the mesocorticolimbic system. This effect is reflected in neuroadaptative changes that can modulate neurotransmission in the prefrontal cortex (PFC) and nucleus accumbens (NAcc) core (cNAcc) and shell (sNAcc) regions. We evaluated the effect of chronic administration of nicotine (4.23 mg/kg/day for 14 days) on NMDA activated currents in dissociated neurons from the PFC, and NAcc (from core and shell regions). We assessed nicotine blood levels by mass spectrophotometry and we confirmed that nicotine increases locomotor activity. An electrophysiological study showed an increase in NMDA currents in neurons from the PFC and core part of the NAcc in animals treated with nicotine compared to those of control rats. No change was observed in neurons from the shell part of the NAcc. The enhanced glutamatergic activity observed in the neurons of rats with chronic administration of nicotine may explain the increased locomotive activity also observed in such rats. To assess one of the possible causes of increased NMDA currents, we used magnesium, to block NMDA receptor that contains the NR2B subunit. If there is a change in percent block of NMDA currents, it means that there is a possible change in expression of NMDA receptor subunits. Our results showed that there is no difference in the blocking effect of magnesium on the NMDA currents. The magnesium lacks of effect after nicotinic treatment suggests that there is no change in expression of NR2B subunit of NMDA receptors, then, the effect of nicotine treatment on amplitude of NMDA currents may be due to an increase in the quantity of receptors or to a change in the unitary conductance, rather than a change in the expression of the subunits that constitute it.

Satisfação com a vida na percepção dos idosos / Satisfaction with life seniors perception

Foi realizada uma pesquisa qualitativa à luz da Grounded Theory, objetivando compreender os fatores associados à satisfação com a vida, em idosos, no município de Barreiras (BA). A metodologia escolhida foi qualitativa. Como pergunta norteadora, foi solicitado ao entrevistado que falasse espontaneamente sobre satisfação com a vida. Foram entrevistados vinte e um idosos, escolhidos por conveniência, provenientes de classes socioeconômicas e culturais e idades diversificadas. As entrevistas foram gravadas e registradas em mp3 e o conteúdo transcrito na íntegra. A análise dos dados foi realizada à luz da teoria fundamentada em dados (Grounded Theory) e representada através do Simbolismo Teórico. Os resultados estão representados na descrição de três fenômenos que se integraram e interrelacionaram ao longo da experiência vivida, no que tange à satisfação com a vida. Estes constituíram os vértices na base do tripé que convergiram para o que aparenta ser o sentido da satisfação com a vida, entre eles: “Elegendo as Relações de Afeto e Cumplicidade com a Família, Amigos e Lazer”; “Encontrando a Felicidade na Vida, como a Construiu”; Compreendendo as Condições de Saúde e as Necessidades da sua Prevenção como seus Determinantes”. Desse modo, a satisfação com a vida entre os idosos não apareceu apenas como um recorte de um ponto específico, mas sim como uma trajetória ao longo da vida que lhes proporcionou momentos de felicidade, atitudes e vontades, indo além dos desdobramentos e implicações que a idade avançada lhes reserva. Depois de descobertos esses fenômenos, buscamos padrões de conectividade entre seus componentes para conceitualizar a categoria central e conseguimos entender os pontos-chave que nos permitiram retratar a experiência dos idosos do município de Barreiras (BA), durante sua vida, associada com o grau de satisfação.

A research was conducted aiming to understand the factors associated with life satisfaction in the elderly, in Barreiras (BA). The methodology chosen was qualitative. As a guiding question it was asked to the interviewed to talk freely about life satisfaction. Twenty-one seniors were interviewed, chosen by convenience, from different socioeconomic and cultural classes and several ages. The interviews were recorded and registered in mp3 format and it content was transcript in full. Data analysis was conducted considering the Grounded Theory and represented by Symbolism Theory. The results are shown in the description of three phenomena that were interrelated and integrated throughout the experience of life, when it comes to life satisfaction. These were the vertices in the base of the tripod that converged to what appears to be a sense of satisfaction with life, among them "Electing Affection Relations And Complicity With The Family, Friends And Leisure"; "Finding Happiness In Life, As It Was Built"; "Understanding Health Conditions And The Requirements Of Its Prevention As Their Determinants." Thus, satisfaction with life among the elderly, not only appeared as a clipping of a specific point, but as a lifelong path that gave moments of happiness, attitudes and desires, beyond the ramifications and implications that old age holds. After discovered these phenomena, we seek for patterns of connectivity between their components to conceptualize the core category and we understood the key points that allowed us to portray the experience of elderly in Barreiras - BA, during their lifetime, associated with the degree of satisfaction.

[Community health workers' attitudes and beliefs toward the elderly]. / Atitudes e conhecimentos de agentes comunitários de saúde e suas relações com idosos.

OBJECTIVE: To describe community health workers' attitudes and beliefs toward the elderly. METHODS: Cross-sectional descriptive study conducted in with 213 community health workers (CHWs) at 12 primary care units and 29 family health centers in the city of Marília, State of São Paulo, Southeastern Brazil, in 2010. Data were collected by means of a sociodemographic questionnaire, a scale of attitudes toward aging (Neri Scale), and a questionnaire to assess gerontological knowledge (the Palmore-Neri-Cachioni Aging Quiz). The Statistical Package for the Social Sciences v. 16.0 was used for data analysis. RESULTS: Community health workers predominantly consisted of young female adults, married, with more than 12 years of schooling and who worked in this activity for over 6 years. Most CHWs reported having experience with elderly people and having elderly people in the family. However, less than half of them received training on the topic of aging. As for attitudes towards the elderly, CHWs stressed both positive aspects such as their wisdom and generosity and negative aspects such as slowness and strictness. They showed low gerontological knowledge, which was directly associated with the training received. Many CHWs stereotyped the elderly as dissatisfied and dependent. CONCLUSIONS: Changing attitudes and improving knowledge on aging are critical for meeting health care demands of elderly people. More appropriate training of CHWs is key for providing adequate primary care to elderly population.

Atitudes e conhecimentos de agentes comunitários de saúde e suas relações com idosos / Community health workers' attitudes and beliefs toward the elderly / Actitudes y conocimientos de agentes comunitarios de salud y sus relaciones con ancianos

OBJETIVO: Analisar as relações entre agentes comunitários de saúde e os cuidados prestados a idosos. MÉTODOS: Estudo transversal descritivo, com 213 agentes comunitários das 12 unidades básicas de saúde e das 29 unidades de saúde da família de Marília em 2010. Os dados foram coletados por meio de um questionário sociodemográfico, um instrumento de escala de atitudes em relação à velhice (Escala de Neri) e um questionário para avaliar conhecimentos gerontológicos (Questionário Palmore-Neri-Cachioni). Para a análise dos dados, foi utilizado o programa Statistical Package for the Social Sciences versão 16.0 para Windows. RESULTADOS: Predominaram no quadro dos agentes comunitários os adultos jovens, do sexo feminino, casados, escolaridade > 12 anos e inseridos na atividade há mais de seis anos. A maioria dos agentes relatou experiência com grupo de idosos e convivência intradomiciliar com pessoas dessa faixa etária, porém menos da metade referiu capacitação no tema envelhecimento. As avaliações positivas dos agentes quanto às atitudes perante a velhice ocorreram principalmente em aspectos como a sabedoria e generosidade dos idosos, porém foram marcantes as atitudes negativas para "lentidão e rigidez". O número de acertos sobre gerontologia foi baixo e esteve diretamente associado às capacitações recebidas pelos agentes. Foram observados estereótipos em relação ao idoso, na medida em que muitos agentes os consideravam insatisfeitos e dependentes. CONCLUSIONES: Mudar as atitudes e melhorar o conhecimento que se tem acerca do envelhecimento é essencial no enfrentamento das demandas advindas dessa fase da vida. Qualificar a formação do agente comunitário de saúde é fundamental no cuidado ao idoso na atenção primária.

RESULTADOS: Predominaron en la plantilla de los agentes comunitarios los adultos jóvenes, del sexo femenino, casados, con escolaridad > 12 años e insertados en la actividad por más de seis años. La mayoría de los agentes narró experiencia con grupo de ancianos y convivencia intra-domiciliar con personas de dicho grupo etario, sin embargo, menos de la mitad refirió capacitación en el tema del envejecimiento. Los agentes tuvieron evaluaciones positivas con respecto a las actitudes frente a la vejez en aspectos como la sabiduría y generosidad de los ancianos, por otro lado, resaltaron las actitudes negativas para "lentitud y rigidez". El número de aciertos sobre gerontología fue bajo y estuvo directamente asociado con las capacitaciones recibidas por los agentes. Se observaron estereotipos con relación al anciano, en la medida en que muchos agentes los consideraban insatisfechos y dependientes. CONCLUSIONES: Cambiar las actitudes y mejorar el conocimiento que se tiene sobre el envejecimiento es esencial en el enfrentamiento de las demandas que advienen en la vida. Calificar la formación del agente comunitario de salud es fundamental en el cuidado del anciano en la atención primaria.

Inserção, renda e satisfação profissional de médicos formados pela Unesp / Professional insertion, income and satisfaction of physicians graduated from Unesp

OBJETIVO: Avaliar a inserção profissional, o nível de renda e de satisfação de médicos formados na Faculdade de Medicina de Botucatu (Unesp) assim como possíveis fatores associados a tais desfechos. MÉTODOS: Estudo transversal, tendo como população-alvo todos os médicos formados entre 1968 e 2005, utilizando-se um questionário autoaplicável. RESULTADOS: A taxa de resposta foi de 45%, 1.224 dos 2.864 questionários enviados por correio. A média de idade dos participantes foi de 46,5 anos (± 10,9) e 64,4% eram homens. A maioria (98,6%) referiu exercer a profissão, residir no Estado de São Paulo (96,4%), ter feito residência (92,0%) e frequentar eventos científicos regularmente (80,2%). Referiram morar em cidades do interior 70,4% e ter clínica privada 67,4% dos egressos. Renda mensal entre R$ 10 e 15 mil foi relatada por 28,4% e satisfação profissional grande ou muito grande por 66,1% deles. Nos modelos de regressão logística, mantiveram-se significativamente associados a maior renda: sexo masculino, ter clínica privada, ter filhos e estar profissionalmente satisfeito. Maior satisfação associou-se com menor idade e maior renda, fazer doutorado, considerar que foi bem preparado para a profissão, afirmar que faria Medicina novamente e avaliar positivamente sua qualidade de vida e saúde mental. CONCLUSÕES: A inserção profissional de ex-alunos é importante na avaliação institucional, devendo ser realizada regularmente para subsidiar as discussões sobre reforma curricular.

OBJECTIVE: Evaluatethe professional insertion, income and satisfaction of physicians who graduated from Botucatu Medical School (UNESP), as well as possible risk factors associated with these outcomes. METHOD: A cross-sectional study with a target population of all physicians graduated between 1968 and 2005, using a self-reporting questionnaire. RESULTS: The response rate was 45%, 1,224 of the 2,864 questionnaires sent by mail. The participants' mean age was 46.5 years old (± 10.9) and 64.4% of them were men. The majority of them were practicing as medical doctors (98.6%), in São Paulo state (96.4%); 92.0% reported having received residence training and 80.2% reported attending scientific events on a regular basis. Most of them did not live in the capital cities (70.4%) and reported having some private practice (67.4%). A monthly income of 10 to 15 thousand reais was reported by 28.4% and a high or very high degree of professional satisfaction by 66.1% of them. Logistic regression analysis showed the following variables as significantly associated with higher income: male gender, private practice, having children and being satisfied with the profession. Higher satisfaction was associated with younger age, higher income, taking a post graduate (PhD) course, considering oneself well prepared for the profession, stating that he/she would attend Medical School again and evaluating positively one's quality of life and mental health. CONCLUSION: The professional insertion of ex-students is an important aspect of institutional evaluation and should be conducted regularlyin order to support discussions regarding curricular reform.

Sintomas depressivos e déficit cognitivo na população de 60 anos e mais em um município de médio porte do interior paulista* / Depression symptoms and cognitive-deficit in a population aged 60 years and older in a medium-sized city in São Paulo state, Brazil / Síntomas depresivos y de déficit cognitivo en la población de 60 años y más en una ciudad de tamaño medio en el estado de São Paulo, en Brasil

Introdução: a população mundial está envelhecendo e o Brasil segue essa tendência, o que demanda uma reorganização da sociedade para o cuidado desses idosos. Observa-se, nesta tendência, um aumento do número de casos de depressão e demência, além da vinculação destas com outras doenças crônico-degenerativas. Objetivo: estimar a prevalência dos sintomas depressivos e déficits cognitivos em uma população de 60 anos e mais, moradora de um município de médio porte do interior do estado de São Paulo, e sua associação com outras doenças crônico-degenerativas mais prevalentes. Métodos: estudo transversal, com 364 idosos, utilizando: instrumentos sociodemográficos e de morbidade; o Mini Exame do Estado Mental (MEEM), a Escala de Yesavage, a Escala de Atividades de Vida Diária e a Escala de Atividades Instrumentais de Vida Diária (AIVD). Foram realizadas: análises estatísticas de frequências dos escores dos instrumentos; apresentação da sumarização das variáveis e as possíveis associações entre depressão/demência, aplicando-se o teste do X2 seguido do ajuste de um modelo de regressão logística para dados ordinais. Resultados: a suspeita de depressão foi encontrada em 44% (160) e o déficit cognitivo foi identificado em 38,7% (141) dos idosos. Aproximadamente 75% dos idosos, com suspeita de depressão ou déficit cognitivo, eram portadores de pelo menos mais uma patologia crônica. Foi possível estabelecer associações estatisticamente significativas entre: suspeita de depressão e AIVD (p<0,0001; OR=7,59; IC=3,361-7,139) e déficit cognitivo e AIVD (p=0,0007; OR=3,967; IC=1,788-8,799). Não foram encontradas associações entre idade, situação conjugal, escolaridade, inserção no mercado de trabalho, aposentadoria ou renda. Conclusão: idosos de ambos os sexos estão vulneráveis a doenças como depressão e demência. Por outro lado, sintomas depressivos e déficit cognitivo foram associados ao escore dos idosos comprometidos, segundo as AIVD. *Parte da Dissertação de Mestrado apresentada à Faculdade de Medicina de Botucatu para a obtenção do Título de Mestre em Saúde Pública.

Introduction: the world population is ageing, and Brazil follows this tendency, which requires the reorganization of society for care provision to older people. In such tendency, an increasing number of cases of depression and dementia is observed in addition to their association with other chronic-degenerative diseases. Objective: to estimate the prevalence of depression and cognitive-deficit symptoms in a population aged 60 years and older, residing in a middle-sized city in São Paulo state and to associate the population with other more prevalent chronic degenerative diseases. Methods: cross-sectional study on 364 older people using the following instruments: socio-demographic and morbidity, Mini Mental State Examination, Yesavage Scale, the Activities of Daily Living Scale, and the Instrumental Activities of Daily Living (IADL) Scale. The following were performed: statistical analyses of the instruments' score frequencies; presentation and summarization of the variables; and the possible associations between depression/dementia by applying the X2 test followed by fitting of a logistic regression model for ordinal data. Results: the suspected depression was found in 44% (160), and cognitive deficit was observed in 38.7% (141) aged. About 75% of the individuals with suspicion of depression or cognitive deficit had at least another chronic pathology. It was possible to establish statistically significant associations between suspected depression and IADL (p<0.0001; OR=7.59; CI=3.361-7.139) and cognitive deficit and IADL (p=0.0007; OR=3.967; CI=1.788-8.799). No associations were found between age, marital status, schooling, placement in the work market, retirement or income. Conclusion: male and female older individuals are vulnerable to diseases, such as depression and dementia. On the other hand, depression symptoms and cognitive deficit were associated with the score of compromised older individuals, according to IADL.

Introducción: la población mundial está envejeciendo y Brasil sigue esta tendencia, que requiere una reorganización de la sociedad para el cuidado de los ancianos. Acepta-se que este número creciente de casos de la depresión y la demencia están asociados con otras enfermedades crónicas. Objetivo: estimar la prevalencia de los síntomas depresivos y deterioros cognitivos en una población de 60 años y más de edad, residente en una ciudad de tamaño medio en el Estado de São Paulo y su asociación con las enfermedades crónicas más frecuentes. Métodos: estudio transversal con 364 pacientes, utilizando los siguientes instrumentos: variables socio-demográficas y de morbilidad, el Mini Examen del Estado Mental, Yesavage Escala y Escala de Actividades de la Vida y Actividades Instrumentales de la Vida Diaria. Se realizaron: análisis estadísticos de frecuencias de las puntuaciones de los instrumentos; la presentación de los resúmenes de las variables y se estudiaran las posibles asociaciones entre la depresión y la demencia mediante la aplicación de la prueba de X2 seguido por el ajuste de un modelo de regresión logística para datos ordinales. Resultados: la depresión fue encontrada en el 44% (160) y el deterioro cognitivo fue identificado en 38,7% (141) de las personas mayores. En aproximadamente el 75% de los pacientes ancianos con depresión, también se sospechó de deterioro cognitivo en los pacientes que tuvieron al menos una enfermedad más crónica. Fue posible establecer asociaciones estadísticamente significativas entre: sospecha de depresión y AIVD (p<0,0001, OR=7.59, IC=3,361-7,139) y déficit cognitivo y AIVD (p=0,0007; OR=3,967; IC=1,788-8,799). No se encontró asociación entre sospecha de depresión y déficit cognitivo con la edad, el estado civil, la educación, la entrada en el mercado de trabajo, los ingresos o la jubilación. Conclusión: los adultos mayores de ambos los sexos son vulnerables a enfermedades como la depresión y la demencia. Por otra parte, los síntomas depresivos y el déficit cognitivo fueron asociados a la puntuación de los ancianos comprometidos, segundo el AIVD.

Distribuição espacial dos idosos no município de Botucatu segundo o grau de atividade física em atividades de recreação e lazer / Spatial distribution of aged people in the city of Botucatu according to their level of physical activity in recreation and leisure activities / Distribución espacial de los ancianos en la ciudad de Botucatu en el grado de actividad física de ocio y tiempo libre

Introdução: À medida que a população envelhece, cresce a preocupação com a manutenção da sua qualidade de vida e capacidade funcional, que estão associadas ao grau de atividade física mantida. O uso de técnicas de geoprocessamento possibilita a análise espacial de dados de saúde, relacionando-os às características da população estudada, o que permite a o direcionamento de ações a grupos de risco específicos. Objetivo: Estudar a distribuição espacial da população de sessenta anos e mais do município de Botucatu segundo seu grau de atividade física. Métodos: Foi realizada uma amostragem sistemática populacional por famílias. Dessas que possuíam idosos, foram sorteados 365 correspondente a uma prevalência de 50% com uma margem de erro de 5% e confiança de 95%. A esses idosos, foi aplicado vários intrumentos para avaliar qualidade e estilo de vida, dentre eles o International Physical Activities Questionaire (IPAQ). Utilizando o domínio de atividades físicas, esporte, recreação, lazer esses idosos foram classificados como muito ativo, ativo, irregularmente ativo e sedentário, como proposto por Matsudo (2001). Para avaliar a distribuição espacial dos idosos segundo o grau de atividade física de lazer, utilizou-se o indice de Moran. As abálises foram feitas através do programa GeoDa. Resultados: Observou-se que o grau de atividade física é baixo e que existe associação entre os locais de oferta para a prática de esportes, topografia e o grau de atividade física. Não foi observada relação entre o grau de atividade física e o sexo ou a idade dos entrevistados. Conclusão: Aumento e melhor distribuição da estrutura para a prática de atividade física ajudaria a melhorar a atividade desta faixa etária e, portanto, sua qualidade de vida.

Introduction: As the population ages, there is increasing concern about the maintenance of people's quality of life and functional capacity, which are associated with their level of activity performed. The use of geoprocessing techniques enables the spacial analysis of health data by relating them to the characteristics of the studied population, and this allows for targeting actions at specific risk groups. Objectives: To study the spatial distribution of the populaiton of individuals aged 60 years and over in the city of Botucatu, SP according to their level of physical activity. Methods: Systematic population sampling by families was performed. Of the families comprising elderly members, 365 were randomly selected, corresponding to a prevalence of 50% with a margin of error of 5% and confidence of 95%. Various instruments were applied to the older individuals in order to evaluate quality of life and lifestyle, such as the International Physical Activity Questionnaire (IPAQ). By using the domain of physical activities, sports, recreation and leisure, the older individuals were classified as very active, active, irregularly active and sedentary, according to Matsudo (2001). To evaluate the older people's spatial distribution based on their level of leisure physical activity, Moran's index was used. Analyses were performed by the GeoDa software. Results: It was observed that the level of physical activity was low, and that there was association between the sites provided for sports practice, topography and the level of physical activity. No relation was observed between physical activity level and the respondents' gender or age. Conclusion: Increase and better distribution of the structure for physical activity practice would help improve physical activity at this age range and, therefore, the individuals' quality of life.

Introducción: A medida que la población envejece, una creciente preocupación por el mantenimiento de su calidad de vida y capacidad funcional, que se asocian con el grado de actividad física mantenida. El uso de técnicas de SIG permite el análisis espacial de datos de salud, en relación a las características de la población estudiada, lo que permite las acciones directas de los grupos de riesgo específi cos. Objetivo: Estudiar la distribución espacial de la oblación de 60 años o más de Botucatu, de acuerdo a su grado de actividad física. Métodos: Se realizó un muestreo sistemático por hogar. De los que tenían más edad, se extrajeron 365 que corresponde a una prevalencia del 50% con un margen de error del 5% y el 95% de confi anza. A estos ancianos, se les aplicó diversos instrumentos para evaluar la calidad y el estilo de vida, incluyendo el Cuestionario Internacional de Actividad Física (IPAQ). Mediante el dominio de la actividad física, deporte, recreación y esparcimiento, estos ancianos fueron clasifi cados como muy activos, activos, de forma irregular activa y sedentarios, según lo que fue propuesto por Matsudo (2001). Para evaluar la distribución espacial de las personas mayores en función del grado de actividad física de ocio, se utilizó el índice de Moran. El análisis se hizo a través de la GeoDa programa. Resultados: Se observó que el grado de actividad física es bajo y que existe una asociación entre la oferta local de los deportes, la topografía y el grado de actividad física. No se encontró relación entre el grado de actividad física y el sexo o la edad de los encuestados. Conclusión: El aumento y una mejor distribución del marco de la actividad física ayudarían a mejorar la actividad de este grupo de edad y por lo tanto su calidad de vida.
