RESUMO
BACKGROUND: Postoperative recurrence remains a significant problem in Crohn's disease, and the mesentery is implicated in the pathophysiology. The Kono-S anastomosis was designed to exclude the mesentery from a wide anastomotic lumen, limit luminal distortion and fecal stasis, and preserve innervation and vascularization. OBJECTIVE: To review postoperative complications and long-term outcomes of the Kono-S anastomosis in a large series of consecutive unselected patients with Crohn's disease. DESIGN: Retrospective study of prospectively collected patients. SETTINGS: Four tertiary referral centers. PATIENTS: Consecutive patients with Crohn's disease who underwent resection with Kono-S anastomosis between May 2010 and June 2022. INTERVENTIONS: Extracorporeal handsewn Kono-S anastomosis. MAIN OUTCOME MEASURES: Postoperative outcomes and recurrence defined as endoscopic, clinical, laboratory, or surgical, including endoscopic, intervention. RESULTS: A total of 262 consecutive patients (53.4% male) were included. The mean duration of disease at surgery was 145.1 months. One hundred thirty-five patients (51.5%) had previous abdominal surgery for Crohn's disease. Forty-four patients (17%) were actively smoking and 150 (57.3%) were on biologic therapy. Anastomotic failure occurred in 4 (1.5%), with 2 patients requiring reoperation (0.7%). Sixteen patients had postoperative surgical site infection (6.1%). With a median follow-up of 49.4 months, 20 patients (7.6%) were found to have surgical recurrence. In the multivariate analysis, perianal disease (OR = 2.83, p = 0.001), urgent/emergent surgery (OR = 3.23, p = 0.007), and postoperative use of steroids (OR = 2.29, p = 0.025) were associated with increased risk of overall recurrence. LIMITATIONS: Retrospective study and variability of perioperative medical therapy. CONCLUSIONS: This study showed very low postoperative complication rates despite the complexity of the patient population. There was a low rate of surgical recurrence, likely due to the intrinsic advantages of the anastomotic configuration and the low rate of postoperative septic complications. In experienced hands, the Kono-S anastomosis is a safe technique with very promising short- and long-term results. Randomized controlled trials are underway to validate this study's findings.

RESULTADO A LARGO PLAZO DE LA ANASTOMOSIS KONOS UN ESTUDIO MULTICNTRICO: ANTECEDENTES:La recurrencia posoperatoria sigue siendo un problema importante en la enfermedad de Crohn y el mesenterio está implicado en la fisiopatología. La anastomosis Kono-S fue diseñada para excluir el mesenterio de una anastomosis amplia, limitar la distorsión luminal y la estasis fecal y preservar la inervación y vascularización.OBJETIVO:Revisar las complicaciones posoperatorias y los resultados a largo plazo de la anastomosis Kono-S en una gran serie de pacientes consecutivos no seleccionados con enfermedad de Crohn.DISEÑO:Estudio retrospectivo de pacientes recolectados prospectivamente.ESCENARIO:Cuatro centros de referencia terciarios.PACIENTES:Pacientes consecutivos con enfermedad de Crohn sometidos a resección con anastomosis Kono-S entre mayo de 2010 y junio de 2022.INTERVENCIONES:Anastomosis Kono-S extracorpórea manual.PRINCIPALES MEDIDAS DE RESULTADO:Resultados posoperatorios y recurrencia definidos como endoscópicos, clínicos, de laboratorio o quirúrgicos, incluida la intervención endoscópica.RESULTADOS:Se incluyeron un total de 262 pacientes consecutivos (53,4% varones). La duración media de la enfermedad al momento de la cirugía fue de 145,1 meses. Ciento treinta y cinco pacientes (51,5%) habían tenido cirugía abdominal previa por enfermedad de Crohn. Cuarenta y cuatro pacientes (17%) eran fumadores activos y 150 (57,3%) estaban en tratamiento biológico. Se produjo filtración anastomótica en 4 (1,5%) y 2 pacientes requirieron reoperación (0,7%). Dieciséis pacientes tuvieron infección postoperatoria del sitio quirúrgico (6,1%). Con una mediana de seguimiento de 49,4 meses, se encontró que 20 pacientes (7,6%) tuvieron recurrencia quirúrgica. En el análisis multivariado, la enfermedad perianal (OR = 2,83, p = 0,001), la cirugía urgente/emergente (OR = 3,23, p = 0,007), el uso postoperatorio de esteroides (OR = 2,29, p = 0,025) se asociaron con un mayor riesgo de recurrencia general.LIMITACIÓN:Estudio retrospectivo. Variabilidad del tratamiento médico perioperatorio.CONCLUSIONES:Nuestro estudio mostró tasas de complicaciones postoperatorias muy bajas a pesar de la complejidad de la población de pacientes. Hubo una baja tasa de recurrencia quirúrgica, probablemente debido a las ventajas intrínsecas de la configuración anastomótica y la baja tasa de complicaciones sépticas posoperatorias. En manos experimentadas, la anastomosis Kono-S es una técnica segura con resultados muy prometedores a corto y largo plazo. Se están realizando estudios randomizados controlados para validar nuestros hallazgos. (Traducción-Dr. Felipe Bellolio ).

We used historical DNA samples to examine the history of a native horse breed, the Finnhorse. Samples were collected from private collections, museums, schools and excavations, representing the times prior to, during, and after the foundation of the breed; from the end of the 19th century and throughout the 20th century. We sequenced a fragment of mitochondrial DNA from these historical samples to study the history and evolution of maternal lineages of horses back to the early days of the breed, compared the mitochondrial DNA sequence diversity of different historical periods and modern day Finnhorses, estimated the effective population sizes, and searched for both temporal and geographic population genetic structure. We observed high maternal haplotype and nucleotide diversity at the time during the foundation of the breed, and a decrease in both measures during 1931-1970. In addition, we observed losses of some haplotypes present in the early stages of the breed. There was only slight evidence of geographical or temporal population structure. This study is, to our knowledge, the first to use such temporal sampling to reveal the history of a specific animal breed.

BACKGROUND: Adiposity is a major component of the metabolic syndrome (MetS), low muscle strength has also been identified as a risk factor for MetS and for cardiovascular disease. We describe the prevalence of MetS and evaluate the relationship between muscle strength, anthropometric measures of adiposity, and associations with the cluster of the components of MetS, in a middle-income country. METHODS: MetS was defined by the International Diabetes Federation criteria. To assess the association between anthropometric variables (waist circumference (WC), waist-to-hip ratio (W/H), body mass index (BMI)), strength (handgrip/kg bodyweight (HGS/BW)) and the cluster of MetS, we created a MetS score. For each alteration (high triglycerides, low HDLc, dysglycemia, or high blood pressure) one point was conferred. To evaluate the association an index of fat:muscle and MetS score, participants were divided into 9 groups based on combinations of sex-specific tertiles of WC and HGS/BW. RESULTS: The overall prevalence of MetS in the 5,026 participants (64% women; mean age 51.2 years) was 42%. Lower HGS/BW, and higher WC, BMI, and W/H were associated with a higher MetS score. Amongst the 9 HGS/BW:WC groups, participants in the lowest tertile of HGS/BW and the highest tertile of WC had a higher MetS score (OR = 4.69 in women and OR = 8.25 in men;p < 0.01) compared to those in the highest tertile of HGS/BW and in the lowest tertile of WC. CONCLUSION: WC was the principal risk factor for a high MetS score and an inverse association between HGS/BW and MetS score was found. Combining these anthropometric measures improved the prediction of metabolic alterations over either alone.

INTRODUCTION: Health-care disparities based on race and socioeconomic status among trauma patients are well-documented. However, the influence of these factors on the management of rib fractures following thoracic trauma is unknown. The aim of this study is to describe the association of race and insurance status on management and outcomes in patients who sustain rib fractures. METHODS: The Trauma Quality Improvement Program database was used to identify adult patients who presented with rib fractures between 2015 and 2016. Patient demographics, injury severity, procedures performed, and outcomes were evaluated. Multivariate logistic regression analysis was used to determine the effect of race and insurance status on mortality and the likelihood of rib fixation surgery and epidural analgesia for pain management. RESULTS: A total of 95,227 patients were identified. Of these, 2923 (3.1%) underwent rib fixation. Compared to White patients, Asians (AOR: 0.57, P = 0.001), Blacks or African-Americans (AA) (AOR: 0.70, P < 0.001), and Hispanics/Latinos (HL) (AOR: 0.78, P < 0.001) were less likely to undergo rib fixation surgery. AA patients (AOR: 0.67, P = 0.004), other non-Whites (ONW) (AOR: 0.61, P = 0.001), and HL (AOR 0.65, P = 0.006) were less likely to receive epidural analgesia. Compared to privately insured patients, mortality was higher in uninsured patients (AOR: 1.72, P < 0.001), Medicare patients (AOR: 1.80, P < 0.001), and patients with other non-private insurance (AOR: 1.23, P < 0.001). CONCLUSIONS: Non-White race is associated with a decreased likelihood of rib fixation and/or epidural placement, while underinsurance is associated with higher mortality in patients with thoracic trauma. Prospective efforts to examine the socioeconomic disparities within this population are warranted.

High blood pressure (BP) is the leading global preventable cause of death and the most common risk factor for cardiovascular disease (CVD). However, due to its asymptomatic nature, the lack of awareness of this condition causes underdiagnosis and low rates of adherence to pharmacological treatment. Looking for practical approaches to increase awareness worldwide, the International Society of Hypertension (ISH) implemented the 2nd May Measurement Month campaign in 2018 (MMM18). In order to contribute to this initiative, Colombia participated as one of the 89 countries involved in this hypertension screening programme. Blood pressure was measured in subjects from 11 departments in Colombia. Under the leadership of the Fundación Oftalmológica de Santander (FOSCAL), 400 volunteers across the country collected the data following the MMM protocol. Measurements from 35 548 participants with a mean age of 41.9 years were obtained. In total, 9475 (26.7%) of the total population studied had hypertension. Of those with hypertension, 69.9% of these subjects were aware of their condition, 65.0% were on antihypertensive medication, and 43.1% had controlled BP. Of those on medication, 66.3% had controlled BP. Hypertension screening, awareness, treatment, and control should be a priority in public health objectives due to its elevated burden of disease and direct association with increased CVD. The MMM campaign provided a positive impact in the diagnosis of hypertension across Colombia. Although efforts are being made to expand treatment capability and adherence, still more are needed to insure a broader coverage of antihypertensive medication in Colombia.
RESUMO
BACKGROUND AND OBJECTIVES: Outcome data after surgery for cancer in Sub-Saharan Africa are insufficient. We aimed to describe the presentation and outcomes of patients with solid cancers managed at a tertiary hospital in Ghana. METHODS: Records of cancer patients admitted to Komfo Anokye Teaching Hospital general surgery wards from 2013 to 2016 were reviewed for data on presentation, staging, management, and mortality. Patients discharged alive were followed-up by biannual telephone calls to establish their postdischarge status. Survival analysis was performed for patients with pathologic or radiologic confirmation of cancer and adequate staging. RESULTS: A total of 343 patients were included. Of these, 76% were female. The most common diagnoses were breast 136 (40%), foregut 70 (20%), and colorectal 63 (18%) cancers. Cancer diagnosis was confirmed by pathology or radiology in 281 (82%) patients, but only 112 (40%) had adequate staging. Seventy-four (66%) patients were stage IV. Two-year overall survival for all 343 patients was 22% to 69%, depending on cancer site. Among those with adequate staging who were alive after postoperative 90 days, 3-year survival was similar for curative compared with palliative operations (P = 0.64). CONCLUSIONS: Improved capacity for both therapeutic and palliative cancer care is needed to achieve better outcomes by more appropriate allocation of surgery with respect to the goal of treatment.

G. L. Stebbins' most effective pollinator principle states that when pollinators are not limiting, plants are expected to specialize and adapt to the most abundant and effective pollinator species available. In this study, we quantify the effectiveness of bees, hummingbirds and hawkmoths in a Chilean population of Erythranthe lutea (Phrymaceae), and examine whether flower traits are subject to pollinator-mediated selection by the most effective pollinator species during two consecutive years. Unlike most species in the pollinator community, the visitation rate of the recently arrived Bombus terrestris did not change substantially between years, which together with its high and stable pollen delivery to flower stigmas made this species the most important in the pollinator assemblage, followed by the solitary bee Centris nigerrima Flower traits were under significant selection in the direction expected for short-tongue bees, suggesting that E. lutea is in the initial steps of adaptation to the highly effective exotic bumblebee. Our results illustrate the applicability of Stebbins' principle for new invasive pollinators, and stress their importance in driving flower adaptation of native plant species, a critical issue in the face of biotic exchange and homogenization.

Anthropogenic habitat disturbance is a strong biodiversity change driver that compromises not only the species persistence but also the ecological interactions in which they are involved. Even though seed dispersal is a key interaction involved in the recruitment of many tree species and in consequence critical for biodiversity maintenance, studies assessing the effect of different anthropogenic disturbance drivers on this interaction have not been performed under a meta-analytical framework. We assessed the way habitat fragmentation and degradation processes affect species diversity (abundance and species richness) and interaction rates (i.e., fruit removal and visitation rates) of different groups of seed-disperser species at a global scale. We obtained 163 case studies from 37 articles. Results indicate that habitat degradation had a negative effect on seed-disperser animal diversity, whereas habitat fragmentation had a negative effect on interaction rates. Birds and insects were more sensitive in terms of their diversity, whereas mammals showed a negative effect on interaction rates. Regarding habitat, both fragmentation and degradation had a negative effect on seed-disperser animal diversity only in temperate habitats, and negative effects on interaction rates in tropical and temperate habitats. Our results indicate that the impact of human disturbance on seed-disperser species and interactions is not homogeneous. On the contrary, the magnitude of effects seems to be dependent on the type of disturbance, taxonomic group under assessment, and geographical region where the human impact occurs.

Habitat fragmentation and degradation are important biodiversity change drivers worldwide. Their effects have been described for many animal groups, but little is known about marsupials. We conducted a meta-analysis aiming to evaluate the actual effects of habitat fragmentation and degradation on forest marsupials. From a literature survey, we obtained 85 case studies reporting disturbance comparisons. We found a negative overall effect, as well as a negative effect for habitat fragmentation, but not for habitat degradation. Marsupials from Oceania were negatively affected by habitat disturbance, whereas there was no effect for those from South America. Arboreal marsupials were negatively affected, whereas terrestrial marsupials did not. Species from the families Dasyuridae (Antechinus spp.) and Microbiotheriidae (Dromiciops gliroides) showed to be sensitive to habitat disturbance.

The COVID-19 pandemic had a profound global impact, characterized by a high fatality rate and the emergence of enduring consequences known as Long COVID. Our study sought to determine the prevalence of Long COVID syndrome within a population of Northeastern Mexico, correlating it with patients' comorbidities, number of COVID-19 reinfection, and vaccination status. Employing an observational cross-sectional approach, we administered a comprehensive questionnaire covering medical history, demographics, vaccination status, COVID-related symptoms, and treatment. Our participant cohort included 807 patients, with an average age of 41.5 (SD 13.6) years, and women accounting 59.3% of the cohort. The follow-up was 488 (IQR 456) days. One hundred sixty-eight subjects (20.9%) met Long COVID criteria. Long COVID-19 was more prevalent when subjects had reinfections (p = 0.02) and less frequent when they had a complete vaccination scheme (p = 0.05). Through logistic regression, we found that male gender (OR 0.5, p ≤ 0.001), blood types of AB- (OR 0.48, p = 0.003) and O- (OR 0.27, p ≤ 0.001) in comparison with A+ and two doses of vaccines (OR 0.5, p = 006) to be protective factors against Long COVID; while higher BMI (OR 1.04, p = 0.005) was a risk factor. We saw that the prevalence of Long COVID was different within vaccinated patients and specific blood types, while being female and a higher BMI were associated with an increased risk of having long-COVID.

PURPOSE: Peptide receptor radionuclide therapy (PRRT) is an effective and safe treatment of unresectable or metastatic, progressive neuroendocrine tumours (NETs). However, if progression occurs after the initial PRRT, treatment options remain limited. Our aim was to evaluate the efficacy and safety of a repeat 177Lutetium-[DOTA°,Tyr3]octreotate ([177Lu]Lu-DOTA-TATE) PRRT course in patients with progressive NET after the first [177Lu]Lu-DOTA-TATE PRRT (peptide receptor radionuclide therapy first treatment (PRRT1)). METHODS: This is a nine-year retrospective observational study of 20 patients who were re-treated with PRRT (peptide receptor radionuclide therapy retreatment (PRRTR)) after PRRT1. RESULTS: The median progression-free survival (PFS) following PRRT1 was 32 months (interquartile range (IQR): 16.5-44.5). After PRRT1, all 20 patients progressed. Of the 20 patients included, two were lost during follow-up. The median PFS after PRRTR was 17.5 months (IQR: 7-39). At the time of analysis, 15/18 patients progressed, and 3/18 had stable disease after PRRTR. Among those patients who progressed, the median time to progression was nine months (IQR: 0-17). The median overall survival from the time of the first cycle of PRRT1 was 66 months (IQR: 65-90). No significant renal or liver toxicity was reported, nor was there a drop in haemoglobin. The decrease in platelet count after PRRTR was statistically significant (p=0.03). Two cycles at PRRTR (vs. 1) were associated with a longer PFS (p=0.014) and the presence of metastases pre-PRRTR was associated with a shorter time to progression following PRRTR (p=0.04). Conclusion: Patients who progressed after PRRT1 can achieve good PFS and minor toxicity. Our study reinforces the efficacy and safety of PRRTR and provides an analysis of factors associated with better outcomes, which can aid clinicians in clinical decision-making.
RESUMO
BACKGROUND: Pectum excavatum is a congenital thoracic alteration that can present important physiological alterations depending on the severity of the case. The Nuss procedure is a minimally invasive technique for managing chest wall deformity, in which there is a risk of perioperative complications. CASE PRESENTATION: This article presents the case of a 16-year-old patient who underwent placement of a Nuss bar and suffered intraoperative and postoperative cardiorespiratory arrest. CONCLUSIONS: it is important to consider the possible early and late complications scenarios as well as their treatment in patients with pectum excavatum scheduled for a Nuss procedure.

Megaselia scalaris, commonly known as the scuttle fly, is a cosmopolitan species in the family Phoridae. It is an easily cultured fly species that is an emerging model organism in the fields of genetics and developmental biology. Its affinity for carrion and its predictable life cycle makes it useful in the field of forensic science for estimating the post-mortem interval (PMI) of human remains. Cases of human myasis caused by M. scalaris have also been reported in the medical literature. Despite its ubiquitous prevalence and its relevance across multiple fields, its morphology has not been adequately characterized. Here, we report the complete morphological characterization of all lifestages of M. scalaris, ranging from egg to adult. Scanning electron microscopy has enabled us to uncover morphological features and developmental processes that have previously not been reported in the literature. Our data lays the groundwork for future genetic studies: a morphological characterization of the wild type must be performed before mutants displaying different phenotypes can be identified. In this vein, we also report the observation of a acephalic, or 'headless', adult phenotype whose study could yield insights into the process of cephalogenesis. Finally, all morphological features observed have been compiled into an 'atlas' that should be of use to all workers in the field.

Introduction: There is limited evidence on the impact of erector spinae plane block (ESPB) as part of multimodal analgesia in pediatric population undergoing cardiac surgery. Methods: A retrospective cohort study was conducted in patients under 18 years of age, who underwent cardiac surgery Risk Adjusted classification for Congenital Heart Surgery (RACHS-1) ≤3 by sternotomy. The study aims to evaluate the effect of ESPB as part of multimodal analgesia in pediatric patients undergoing cardiac surgery compared to conventional analgesia (CA) on relevant clinical outcomes: length of hospital stay, length of ICU stay, opioid consumption, time to extubation, mortality, and postoperative complications. The participants included were treated in a reference hospital in Colombia from July 2019 to June 2022. Results: Eighty participants were included, 40 in the ESPB group and 40 in the CA group. There was a significant decrease (Log rank test p = 0.007) in days to length of hospital stay in ESPB group (median 6.5 days (IQR: 4-11)) compared to the CA group (median 10.5 days (IQR: 6-25)). Likewise, there was a higher probability of discharge from the ICU in the ESPB group (HR 1.71 (95% CI: 1.05-2.79)). The ESPB group had lower opioid consumption (p < 0.05). There were no differences in time to extubation, mortality, and postoperative complications. Conclusion: ESPB as part of multimodal analgesia in pediatric patients undergoing cardiac surgery is feasible and associated with shorter hospital length of stay, faster ICU discharge and lower opioid consumption.
RESUMO
BACKGROUND: The healthcare sector is responsible for 10% of US greenhouse gas emissions. Telehealth use may decrease healthcare's carbon footprint. Our institution introduced telehealth to support SARS-CoV-2 social distancing. We aimed to evaluate the environmental impact of telehealth rollout. METHODS: We conducted a retrospective cohort study of pediatric patients seen by a surgical or pre anesthesia provider between March 1, 2020 and March 1, 2021. We measured patient-miles saved and CO2 emissions prevented to quantify the environmental impact of telehealth. Miles saved were calculated by geodesic distance between patient home address and our institution. Emissions prevented were calculated assuming 25 miles per gallon fuel efficiency and 19.4 pounds of CO2 produced per gallon of gasoline consumed. Unadjusted Poisson regression was used to assess relationships between patient demographics, geography, and telehealth use. RESULTS: 60,773 in-person and 10,626 telehealth encounters were included. This represented an 8,755% increase in telehealth use compared to the year prior. Telehealth resulted in 887,006 patient-miles saved and 688,317 fewer pounds of CO2 emitted. Demographics significantly associated with decreased telehealth use included Asian and Black/African American racial identity, Hispanic ethnic identity, and primary language other than English. Further distance from the hospital and higher area deprivation index were associated with increased telehealth use (IRR 1.0006 and 1.0077, respectively). CONCLUSION: Incorporating telehealth into pediatric surgical and pre anesthesia clinics resulted in significant CO2 emission reductions. Expanded telehealth use could mitigate surgical and anesthesia service contributions to climate change. Racial and linguistic minority status were associated with significantly lower rates of telehealth utilization, necessitating additional inquiry into equitable telemedicine use for minoritized populations. LEVEL OF EVIDENCE: Level IV.

Introduction Recombinant human growth hormone (rhGH) replacement therapy might be able to induce hypothyroidism, but this is a controversial issue. Previous studies evaluated the effects of rhGH replacement therapy on thyroid function, but little information is available in the subset of children with isolated idiopathic growth hormone deficiency (GHD). Our aim was to assess the effects of rhGH replacement therapy on thyroid function in children with isolated idiopathic GHD. Methods Retrospective analysis of the medical files of 64 children with confirmed GHD treated with rhGH. After review, 56 children with isolated idiopathic GHD and treated with rhGH for at least one year were included. Auxological (weight standard deviation score [SDS], height SDS, growth velocity [GV] SDS) and biochemical (free thyroxine [FT4], thyroid-stimulating hormone [TSH], and insulin-like growth factor 1 [IGF-1]) parameters were recorded before, during, and after treatment with rhGH. Results FT4 and TSH levels decreased significantly during rhGH therapy in children with isolated idiopathic GHD. Twenty-one percent (n=12) of the children developed hypothyroidism, on average 47 months after initiation of rhGH. Higher baseline FT4 levels were protective against the need for levothyroxine (LT4) (OR=0.8, CI 0.592-0.983; p=0.036). Hypothyroidism was reversed after interruption of rhGH, except in one patient; FT4 levels returned to baseline in the first year after completing the treatment. Final height SDS of the children who developed hypothyroidism was not different from their counterparts without hypothyroidism (-1.24 [-1.52 to -1.10] vs -1.13 [-1.78 to -0.74], p=1.000). Predicted adult height (PAH) SDS in patients who completed rhGH treatment was similar in both LT4 supplemented (n=7; final Ht SDS -1.16 [-1.31 to -1.10] vs PAH -1.00 [-1.42 to -0.48]; p=0.398) and not supplemented patients (n=25; final Ht SDS -1.46 [-1.83 to -0.78] vs PAH SDS -0.88 [-1.35 to -0.56]; p=0.074). Conclusions Our results show that patients with isolated idiopathic GHD may transiently need LT4 during GH treatment. Properly supplemented patients achieved PAH.
RESUMO
BACKGROUND: One hour plasma glucose concentration (1hPG) during an oral glucose tolerance test (OGTT) may be an alternative to 2-h plasma glucose concentration (2hPG) in the identification of individuals at increased risk of hyperglycaemia, although its role is not fully understood. AIM: We aim to investigate the relationship of these measures with other glucose parameters, as well as their relationship with cardiometabolic risk markers and the level of agreement for prediabetes mellitus diagnosis, in a sample of patients with morbid obesity. METHODS: We retrospectively evaluated 656 patients with morbid obesity without diagnosed diabetes. To define prediabetes with 2hPG, 2022 American Diabetes Association guidelines criteria were used, while for 1hPG, glucose ≥ 155 mg/dL was considered. Cohen's Kappa coefficient was used to assess the agreement between both measures of prediabetes mellitus diagnosis. RESULTS: A Cohen's Kappa coefficient of 0.405 (p < 0.001) was obtained. The 1hPG were positively correlated with homeostatic model assessment for insulin resistance (HOMA-IR) (ρ = 0.281, p < 0.001), fasting plasma glucose (FPG) (ρ = 0.581, p < 0.001), glycated haemoglobin (Hb1AC) (ρ = 0.347, p < 0.001) and were negatively correlated with homeostatic model assessment for cell-ß function (HOMA-ß) (ρ = -0.092, p = 0.018). 2hPG were also correlated with the same parameters, except for HOMA-ß. CONCLUSION: A fair agreement between 1 and 2hPG was verified. 1hPG criteria may be a useful indicator of ß-cell dysfunction and insulin resistance in patients with morbid obesity without diabetes diagnosis.
RESUMO
PURPOSE: Due to the low incidence and heterogeneous behaviour of medullary thyroid carcinoma (MTC), its prognostic factors are still not well stablished. While several large studies have investigated the impact of gender in differentiated thyroid cancer (DTC), its role in MTC outcomes remains controversial. We aim to identify MTC prognostic features, specially focusing on the role of gender. METHODS: Retrospective analysis of 76 patients diagnosed with MTC between 1984 and 2018 at a Portuguese Comprehensive Cancer Center. RESULTS: Patients presented a median age at diagnosis of 49 years and multiple endocrine neoplasia type 2 (MEN2) was identified in 27.6% of them, with those individuals being significantly younger (P<0.001). Most cases were diagnosed as stage IV disease (46.9%), except for the subgroup detected through pre-symptomatic genetic screening (55.6% at stage I). The 5- and 10-year survival rates were 87.6% and 75.6%, respectively. Univariate analysis identified male gender (P=0.010), age ≥45 years (P=0.007), presence of distant metastasis at diagnosis (P<0.01), capsule invasion (P=0.004), extrathyroidal invasion (P=0.003) and absence of biochemical cure after surgery (P=0.042) as having a negative impact on prognosis. On multivariate analysis, male gender (P=0.046) remained an independent predictor of mortality, as well as an older age (P<0.001) and the presence of distant metastases (P=0.012). CONCLUSIONS: Male gender independently predicted worse survival in MTC patients even after adjusting for age and disease stage. The few older studies on the topic pointed to a behavioural explanation regarding medical care seeking patterns by men, but our study and newer genetic and basic-science oriented publications raise the possibility of a true biological difference between genders in the tumourigenesis of MTC that should me further investigated.
RESUMO
INTRODUCTION: Statin therapy is associated with an increased risk of developing diabetes. Among bariatric patients, the influence of this therapy on various metabolic outcomes, such as diabetes status and its remission, is largely unknown. METHODS: This was a retrospective study of 1710 patients who underwent bariatric surgery at our hospital between January/2010 and June/2017. We compared patients with and without statin therapy at baseline, 12 and 24 months after surgery regarding statin use and its impact on several clinical and analytical parameters. Multiple linear regression was performed, adjusting differences for age, sex, surgery type, antidiabetic drugs at baseline, hypertension at baseline, LDL cholesterol Ë 130 mg/dL, weight variation one year after surgery, and age of obesity onset. RESULTS: The overall prevalence of statin use was 20.2% before, 13.6% 12 months after surgery, and 15.0% 24 months after surgery. There was a larger reduction in fasting glucose and HbA1c at 12 and 24 months after surgery among statin-treated patients, with the opposite trend for weight reduction and BMI. Statin-treated patients with diabetes had lower diabetes remission rates (45.3 vs 68.5%) 12 months after surgery, with the highest reduction in HbA1c (1.3±1.3 vs -1.1±1.2%; p=0.042), fasting glucose (-40.8±48.8 vs -30.9±41.6 mg/dL; p=0.028), and insulin (-21.7±28.2 vs -13.4±14.2 mIU/L; p=0.039). The proportion of new-onset cases of diabetes was equal between statin-treated vs non-treated individuals at 12 months (1.9%) and 24 months (1.0%) after surgery. CONCLUSION: Bariatric surgery seems to lead to diabetes remission more frequently in patients not treated with statins. A larger reduction was observed in fasting glucose and HbA1c among statin-treated patients. Statin did not contribute to an increased proportion of new-onset diabetes after surgery.

BACKGROUND: A higher prevalence of hypertension is reported among Afro-descendants compared with other ethnic groups in high-income countries; however, there is a paucity of information in low- and medium-income countries. METHODS: We evaluated 3,745 adults from 3 ethnic groups (552 White, 2,746 Mestizos, 447 Afro-descendants) enrolled in the prospective population-based cohort study (PURE)-Colombia. We assessed associations between anthropometric, socioeconomic, behavioral factors, and hypertension. RESULTS: The overall prevalence of hypertension was 39.2% and was higher in Afro-descendants (46.3%) than in Mestizos (37.6%) and Whites (41.5%), differences that were due to the higher prevalence in Afro-descendant women. Hypertension was associated with older age, increased body mass index, waist circumference and waist-to-hip ratio, independent of ethnicity. Low education was associated with hypertension in all ethnic groups, and particularly in Afro-descendants, for whom it was the factor with the strongest association with prevalence. Notably, 70% of Afro-descendants had a low level of education, compared with 52% of Whites-26% of Whites were university graduates while only 7% of Afro-descendants were. We did not find that education level alone had a mediator effect, suggesting that it is not a causal risk factor for hypertension but is an indicator of socioeconomic status, itself an important determinant of hypertension prevalence. CONCLUSIONS: We found that a higher prevalence of hypertension in Colombian Afro-descendants than other ethnic groups. This was principally associated with their lower mean educational level, an indicator of lower socioeconomic status.
