RESUMO
Background: Gait speed is associated with a higher prevalence of balance disorders in older adults residing at high altitudes. This study investigated this association in older adults from 12 high-altitude Andean Peruvian communities. Methods: We performed a secondary data analysis from an analytical cross-sectional study of adults >60 years of age, residing in 12 high-altitude Andean Peruvian communities, enrolled between 2013 and 2019. The exposure and outcome variables were gait speed (categorized in tertiles), and balance disorders (defined as a functional reach value of ≤20.32 cm), respectively. We built generalized linear models of the Poisson family with a logarithmic link function and robust variances, and estimated crude prevalence ratios (cPR) and adjusted prevalence ratios (aPR) with 95% confidence intervals (CIs). Results: We analyzed 418 older adults; 38.8% (n=162) were male, and the mean age was 73.2 ± 6.9 years. The mean gait speed and functional reach were 0.66 ± 0.24 m/s and 19.9 ± 6.48 cm, respectively. In the adjusted regression model, the intermediate (aPR=1.88; 95% CI: 1.39-2.55; p<0.001) and low (aPR=2.04; 95% CI: 1.51-2.76; p<0.001) tertiles of gait speed were associated with a higher prevalence of balance disorders. Conclusions: The intermediate and low tertiles of gait speed were associated with a higher prevalence of balance disorders among older adult residents of 12 high-altitude Andean communities. We recommend further research on the behavior of this association to propose interventions for these vulnerable groups and reduce the impact of geriatric conditions.
RESUMO
INTRODUCTION: Sarcopenia and sarcopenic obesity (SO) have emerged as significant contributors to negative health outcomes in the past decade. We aimed to estimate the prevalence of probable sarcopenia, sarcopenia, and SO in a community-dwelling population of 1151 adults aged ≥55 years in Lima, Peru. METHODS: This cross-sectional study was conducted between 2018 and 2020. Sarcopenia was defined as the presence of low muscle strength (LMS) and low muscle mass (LMM) according to European (EWGSOP2), US (FNIH) and Asian (AWGS2) guidelines. We measured muscle strength by maximum handgrip strength and muscle mass using bioelectrical impedance analyzer. SO was defined as a body mass index ≥ 30 kg/m2 and sarcopenia. RESULTS: The study participants had a mean age of 66.2 years (SD 7.1), age range between 60 to 92 years old, of which 621 (53.9%) were men. Among the sample, 41.7% were classified as obese (BMI ≥30.0 kg/m²). The prevalence of probable sarcopenia was estimated to be 22.7% (95%CI: 20.3-25.1) using the EWGSOP2 criteria and 27.8% (95%CI: 25.2-30.4) using the AWGS2 criteria. Sarcopenia prevalence, assessed using skeletal muscle index (SMI), was 5.7% (95%CI: 4.4-7.1) according to EWGSOP2 and 8.3% (95%CI: 6.7-9.9) using AWGS2 criteria. The prevalence of sarcopenia based on the FNIH criteria was 18.1% (95%CI: 15.8-20.3). The prevalence of SO, considering different sarcopenia definitions, ranged from 0.8% (95%CI: 0.3-1.3) to 5.0% (95%CI: 3.8-6.3). CONCLUSION: Our findings reveal substantial variation in the prevalence of sarcopenia and SO, underscoring the necessity for context-specific cut-off values. Although the prevalence of SO was relatively low, this result may be underestimated. Furthermore, the consistently high proportion of probable sarcopenia and sarcopenia point to a substantial public health burden.

Background: There is evidence that sarcopenia and functionality are closely related. However, the association between geriatric syndromes, such as dependence, on instrumental activities and sarcopenia could be affected by the presence of certain comorbidities, such as overweight, obesity, diabetes, and chronic obstructive pulmonary disease (COPD). Therefore, the present study aimed to determine the association between instrumental activities of daily living and muscle mass in the elderly and evaluate the impact of certain comorbidities on this association. Methods: This was a retrospective analytical observational study, including 1897 patients. Muscle mass was measured with calf circumference, and instrumental activities were measured with the Lawton index. Results: Among different parameters studies, a statistical correlation was found in a stratified regression analysis between the Lawton index score and muscle mass in patients who were overweight (p value:0.001 ;beta coefficient: 0.08), obese (p value: 0.001 ; beta coefficient: 0.05), had diabetes (p value: 0.012 ;beta coefficient: 0.03), and had COPD (p value:0.001 ;beta coefficient:0.03). Conclusion: The correlation between muscle mass and instrumental activities of daily living should be evaluated individually according to the needs of each participant and according to their comorbidities, promoting patient-centered geriatric medicine.
RESUMO
BACKGROUND: Sarcopenia is a musculoskeletal disease involving the reduction of muscle mass, strength, and performance. Handgrip strength (HGS) measurements included in frailty assessments are great biomarkers of aging and are related to functional deficits. We assessed the association between potential influencing factors and HGS asymmetry in older Peruvian adults. METHODS: We used a database of the Peruvian Naval Medical Center "Cirujano Santiago Távara" located in Callao, Peru. All the patients included were ≥60 years old and had an HGS measurement in the dominant and non-dominant hand. RESULTS: From a total of 1,468 patients, 74.66% had HGS asymmetry. After adjustment, calf circumference weakness (adjusted prevalence ratio [aPR]=1.08; 95% confidence interval [CI], 1.01-1.15), falls risk (aPR = 1.08; 95% CI, 1.02-1.16), and an altered Lawton index (aPR=0.92; 95% CI, 0.84-0.99) were associated with HGS asymmetry. CONCLUSION: Our findings suggest that HGS asymmetry should be measured along with other geriatric assessments used to evaluate health outcomes in the elderly to enhance health promotion and prevention aimed at preserving muscle strength to curb functional limitations in the elderly.

The possible role of radical species in the formation of the long-lived triplet states observed for 2-thiocytosine upon UV irradiation was theoretically investigated. It is predicted that the radical fragments arising from the homolytic rupture of the NH group of the thiobase can be yielded upon ultraviolet-A radiation. Recombination of the radicals through the most favorable singlet channel yields the lowest-lying tautomer of the 2-thiocytosine (the amino-thiol form) through a barrierless pathway. The rebounding of the radical fragments along the triplet channels that emerge from the attack of the hydrogen to the nitrogen atoms next to the C-S bond leads to stable structures for the amino-thion-N1H and amino-thion-N3H tautomers. These results allow for the rationalization of the near-unity triplet yields observed when this pure light-atom organic molecule is exposed to UV irradiation, without invoking intersystem crossings between the electronic states of different spin-multiplicities. A similar study for cytosine showed that the energy required to induce the homolytic breaking of the N-H bond of the nucleobase is not attainable under UVA radiation. This result is consistent with the experimental fact that no triplet states are observed when this molecule is exposed to that light.
RESUMO
Purpose: Conduct a systematic review of case reports and case series regarding the development of acute abdomen following coronavirus disease 2019 (COVID-19) vaccination, to describe the possible association and the clinical and demographic characteristics in detail. Materials and Methods: This study included case report studies and case series that focused on the development of acute abdomen following COVID-19 vaccination. Systematic review studies, literature, letters to the editor, brief comments, and so forth were excluded. PubMed, Scopus, EMBASE, and Web of Science databases were searched until June 15, 2023. The Joanna Briggs Institute tool was used to assess the risk of bias and the quality of the study. Descriptive data were presented as frequency, median, mean, and standard deviation. Results: Seventeen clinical case studies were identified, evaluating 17 patients with acute abdomen associated with COVID-19 vaccination, which included acute appendicitis (n=3), acute pancreatitis (n=9), diverticulitis (n=1), cholecystitis (n=2), and colitis (n=2). The COVID-19 vaccine most commonly linked to acute abdomen was Pfizer-BioNTech (messenger RNA), accounting for 64.71% of cases. Acute abdomen predominantly occurred after the first vaccine dose (52.94%). All patients responded objectively to medical (88.34%) and surgical (11.76%) treatment and were discharged within a few weeks. No cases of death were reported. Conclusion: Acute abdomen is a rare complication of great interest in the medical and surgical practice of COVID-19 vaccination. Our study is based on a small sample of patients; therefore, it is recommended to conduct future observational studies to fully elucidate the underlying mechanisms of this association.
RESUMO
Introducción: En el Perú la COVID-19 es un tema de interés para la salud pública ya que impacta negativamente a nivel social, económico y psicológico. Según la OMS reportó 769 369 823 casos confirmados de COVID-19 y hasta Agosto del 2023 se han inoculado un total de 13 492 225 267 dosis de vacunas. Objetivo: Determinar si existe asociación entre el conocimiento sobre COVID-19 y la actitud ante la vacunación en los estudiantes de la "Facultad de Ciencias de la Salud" de la "Universidad Científica del Sur" Lima-Perú. Metodología: Se realizó un estudio observacional - analítico- transversal, que buscó analizar el conocimiento sobre COVID-19, utilizando un cuestionario diseñado por investigadores Ortega Paredes y col. y actitudes ante la vacunación utilizando la escala de la revista por Abdul Mannan y col. Los datos fueron analizados en el programa OpenEpi versión 3. Resultados: Fueron encuestado 576 estudiantes de ciencias de la salud, el 20,49 % fueron del sexo masculino, el promedio de edad fue 21,3 con una desviación estándar de 5,93 años. En relación con la variable conocimiento sobre COVID-19, solo 4,17 % tuvieron conocimientos escasos. Se evaluó mediante una escala con 15 preguntas con un puntaje máximo de 24. En promedio, el puntaje de actitud ante la vacunación fue de 3,80 con una desviación estándar de 1,66. Se evaluó mediante una escala de 9 preguntas, el puntaje de la escala osciló entre 0 lo cual significa una actitud totalmente negativa y 9 significa una actitud totalmente positiva. Discusión: En conclusión en un modelo ajustado por variables sociodemográficas y conocimientos sobre terapias no probadas sobre COVID-19 encontramos que un conocimiento adecuado sobre la enfermedad, se asocia con promedios más altos del puntaje de actitudes ante la vacunación por lo cual consideramos importante impartir adecuados conocimientos sobre el COVID-19 para fomentar mejores actitudes ante la vacunación de esta enfermedad, que continuará siendo una infección respiratoria en la cual los médicos debemos tomar en cuenta.
Introduction: In Peru, COVID-19 is a topic of interest for public health since it negatively impacts at a social, economic and psychological level. According to the WHO, 769 369 823 confirmed cases of COVID-19 have been reported and up to August 2023 there have been inoculated a total of 13.492.225.267 doses of vaccines. Objective: To determine if there is an association between knowledge about COVID-19 and the attitude towards vaccination in students of the "Faculty of Health Sciences" of the "Universidad Científica del Sur", Lima-Perú. Methods: An observational-analytical-cross-sectional study was carried out, which sought to analyze knowledge about COVID-19, using a questionnaire designed by the researchers Ortega Paredes et al. and attitudes towards vaccination using the magazine scale by Abdul Mannan et al. The data was analyzed in the OpenEpi version 3 program. Results: 576 health sciences students were surveyed, 20,49% were male, the average age was 21,3 with a standard deviation of 5,93 years. In relation to the knowledge variable about COVID-19, only 4,17% had little knowledge. It was evaluated using a scale with 15 questions with a maximum score of 24. On average, the attitude score towards vaccination was 3,80 with a standard deviation of 1,66. It was evaluated using a nine-question scale, the scale score ranged from 0, which means a totally negative attitude, and nine, meaning a totally positive attitude. Discussion: In conclusion, in a model adjusted for sociodemographic variables and knowledge about unproven therapies on COVID-19, we found that adequate knowledge about the disease is associated with higher average scores for attitudes towards vaccination, for which we consider it important to impart adequate knowledge about COVID-19 to promote better attitudes towards vaccination against this disease, which will continue to be a respiratory infection in which doctors must take into account.
RESUMO
Background: Sarcopenia and sarcopenic obesity (SO) have emerged as significant contributors to negative health outcomes in the past decade. However, there remains a lack of consensus on the criteria and cut-off thresholds for assessing sarcopenia and SO. Moreover, limited data are available on the prevalence of these conditions in Latin American countries. To address this evidence gap, we aimed to estimate the prevalence of probable sarcopenia, sarcopenia, and SO in a community-dwelling population of 1151 adults aged ≥ 55 years in Lima, Peru. Methods: Data collection for this cross-sectional study was conducted between 2018 and 2020 in two urban low-resource settings in Lima, Peru. Sarcopenia was defined as the presence of low muscle strength (LMS) and low muscle mass (LMM) according to European (EWGSOP2), US (FNIH) and Asian (AWGS) guidelines. We measured muscle strength by maximum handgrip strength; muscle mass using a whole-body single-frequency bioelectrical impedance analyzer, and physical performance using the Short Physical Performance Battery and 4-meter gait speed. SO was defined as a body mass index ≥ 30 kg/m2 and sarcopenia. Results: The study participants had a mean age of 66.2 years (SD 7.1), of which 621 (53.9%) were men, and 41.7% were classified as obese (BMI ≥ 30.0 kg/m2). The prevalence of probable sarcopenia was estimated to be 22.7% (95%CI: 20.3-25.1) using the EWGSOP2 criteria and 27.8% (95%CI:25.2-30.4) using the AWGS criteria. Sarcopenia prevalence, assessed using skeletal muscle index (SMI), was 5.7% (95%CI: 4.4-7.1) according to EWGSOP2 and 8.3% (95%CI: 6.7-9.9) using AWGS criteria. The prevalence of sarcopenia based on the FNIH criteria was 18.1% (95%CI: 15.8-20.3). The prevalence of SO, considering different sarcopenia definitions, ranged from 0.8% (95%CI: 0.3-1.3) to 5.0% (95%CI: 3.8-6.3). Conclusions: Our findings reveal substantial variation in the prevalence of sarcopenia and SO when using different guidelines, underscoring the necessity for context-specific cut-off values. Nevertheless, regardless of the chosen guideline, the prevalence of probable sarcopenia and sarcopenia among community-dwelling older adults in Peru remains noteworthy.
RESUMO
INTRODUCTION: COVID-19 related mortality is about 2%, and it increases with comorbidities, like hypertension. Regarding management, there is debatable evidence about the benefits of continuation vs. discontinuation of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARB). AIM: We performed a systematic review to assess the effects and safety of in-hospital discontinuation compared to continuation of ACEI/ARB in COVID-19 patients. METHODS: We systematically searched on PubMed, Scopus, and EMBASE from inception to June 19, 2021. We included observational studies and trials that compared the effects and safety of continuing ACEI/ARB compared to discontinuing it in COVID-19 patients. Effects sizes for dichotomous variables were expressed as risk ratios (RR) and 95% confidence intervals. For continuous variables, effects were expressed as mean difference (MD). We used random effect models with the inverse variance method. We assessed certainty of evidence using the GRADE approach. RESULTS: We included three open-label randomized controlled trials and five cohort studies. We found that the continuation group had lower risk of death compared with the discontinuation group only in the cohort group (RR: 0.46, 95% CI: 0.24-0.90), but not in the RCT group (RR: 1.22, 95% CI: 0.75-2.00). The ICU admission rate was significantly lower in the continuation group (RR: 0.46, 95% CI: 0.31-0.68) in the cohort group, but not in RCT group (RR: 1.03, 95% CI: 0.67-1.59). We did not find significant differences between groups regarding hospitalization length, hypotension, AKI needing renal replacement therapy, mechanical ventilation, new or worsening heart failure, myocarditis, renal replacement therapy, arrhythmias, thromboembolic events and SOFA AUC. The GRADE approach revealed that the certainty ranged from moderate to high level. CONCLUSIONS: There is no significant difference in mortality and other outcomes between continuation and discontinuation groups.

INTRODUCTION: COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread worldwide, becoming a long-term pandemic. OBJECTIVES: To analyze the factors associated with mortality in patients hospitalized for COVID-19 in a tertiary hospital in the Lambayeque region of Peru. METHODS: A retrospective cohort study of patients with a diagnosis of COVID-19, hospitalized in a hospital in northern Peru, was conducted from March to September 2020. RESULTS: Of the 297 patients studied, 69% were women, the mean age was 63.99 years (SD = ±15.33 years). Hypertension was the most frequent comorbidity (36.67%), followed by diabetes mellitus (24.67%) and obesity (8.33%). The probability of survival at 3 days of ICU stay was 65.3%, at 7 days 24.2%, and 0% on day 14. Risk factors associated with mortality in patients hospitalized for COVID-19 are age, male sex, tachypnea, low systolic blood pressure, low peripheral oxygen saturation, impaired renal function, elevated IL-6 and elevated D-dimer. CONCLUSIONS: Mortality in hospitalized patients with COVID-19 was 51.18 per 100 persons, Mortality was found to be associated with hypertension, type of infiltrating, and sepsis.

Background: Older adults are a particularly vulnerable group to drug use and self-medication. The aim of the study was to evaluate self-medication as a factor associated with the purchase of brand-name and over-the-counter (OTC) drugs in older adults in Peru. Methods: A secondary analysis was performed using an analytical cross-sectional design of data from a nationally representative survey from 2014 to 2016. The exposure variable was self-medication, defined as the purchase of medicines without a prescription. The dependent variables were purchases of brand-name and OTC drugs, both as a dichotomous response (yes/no). Information of sociodemographic variables, health insurance, and the types of drugs purchased by the participants was collected. Crude prevalence ratios (PR) were calculated and adjusted using generalized linear models of the Poisson family, considering the complex sample of the survey. Results: In this study, 1,115 respondents were evaluated, with a mean age of 63.8 years and a male proportion of 48.2%. The prevalence of self-medication was 66.6%, while the proportions of purchases of brand-name and OTC drugs were 62.4% and 23.6%, respectively. The adjusted Poisson regression analysis revealed an association between self-medication and the purchase of brand-name drugs (adjusted PR [aPR]=1.09; 95% confidence interval [CI]: 1.01-1.19). Likewise, self-medication was associated with the purchase of OTC medications (aPR=1.97; 95%CI: 1.55-2.51). Conclusions: This study evidenced a high prevalence of self-medication in Peruvian older adults. Two-thirds of the surveyed people bought brand-name drugs, whereas one-quarter bought OTC drugs. Self-medication was associated with a greater likelihood of buying brand-name and OTC drugs.
RESUMO
Introducción: La fuerza de prensión débil suele ser un marcador de dependencia funcional y pobre rendimiento físico, sin embargo, esta asociación es controversial en adultos mayores de 80 años. Objetivo: Determinar la asociación entre la fuerza de prensión y la dependencia funcional y rendimiento físico entre adultos mayores de 80 años. Métodos: El presente estudio es de tipo analítico transversal, fue realizado en 147 sujetos pertenecientes a la Marina de Guerra del Perú. Evaluamos la fuerza muscular, el rendimiento físico, la funcionalidad, las medidas antropométricas y la valoración nutricional. Resultados: Encontramos una asociación significativa entre la fuerza de prensión débil y la dependencia para actividades básicas de la vida diaria (ORa: 2,81, IC95%: 1,32 a 10,11), así como el rendimiento físico alterado (ORa: 4,32, IC95%: 1,97 a 9,59), dichas asociaciones fueron independientes de la edad, número de comorbilidades, síndromes geriátricos, hemoglobina, ferritina, glucosa, colesterol total, linfocitos, vitamina b12, triglicéridos, albúmina sérica, puntaje de MMSE, circunferencia de pantorrilla, circunferencia braquial, IMC, grado de instrucción, estado civil, sexo y índice cintura/cadera. Conclusiones: En los participantes mayores de 80 años, tener una fuerza de prensión débil estuvo asociada con tener fuerza muscular débil y pobre rendimiento físico. Nuestros resultados podrían ser útiles para la inclusión de estas medidas dentro de protocolos de atención hacia poblaciones de edad avanzada y alta comorbilidad. Con ello, se busca mejorar la integridad y atención de los pacientes geriátricos.
Introduction: Weak grip strength is a well-known associated factor with disability and physical performance, but this association is controversial in older adults aged 80 years or more. Objective: To determine the association between prehensile strength and functional dependence and physical performance among adults older than 80 years. Methods: This research was an analytical, cross-sectional study, conducted in 147 older adults aged 80 years or more, from Naval Peruvian Service. We included assessments about muscle strength, physical performance, disability, anthropometric variables, and nutritional assessment. Results: We found a significant association between weak grip strength and dependence for basic activities of daily living (aOR: 2.81, 95% CI: 1.32 to 10.11), as well as altered physical performance (aOR: 4.32, 95% CI: 1.97 to 9.59), these associations were independent of age, number of comorbidities, geriatric syndromes, hemoglobin, ferritin, glucose, total cholesterol, lymphocytes, vitamin B12, triglycerides, serum albumin, MMSE score, calf circumference, brachial circumference, BMI, level of education, marital status, sex, and waist/hip ratio. Conclusions: In persons older than 80 years, having weak grip strength was associated with weak muscle strength and poor physical performance. Our results could be useful for the inclusion of these measures within care protocols for elderly and high comorbidity populations. With this, it seeks to improve the integrity and care of geriatric patients.
RESUMO
Response facilitation has often been portrayed as a "low level" category of social learning, because the demonstrator's action, which is already in the observer's repertoire, automatically triggers that same action, rather than induces the learning of a new action. One way to rule out response facilitation consists of introducing a delay between the demonstrator's behavior and the observer's response to let their possible effects wear off. However, this may not rule out "delayed response facilitation" in which the subject could be continuously "mentally rehearsing" the demonstrated actions during the waiting period. We used a do-as-the-other-did paradigm in two orcas to study whether they displayed cognitive control regarding their production of familiar actions by (1) introducing a delay ranging from 60 to 150 s between observing and producing the actions and (2) interspersing distractor (non-target) actions performed by the demonstrator and by the subjects during the delay period. These two manipulations were aimed at preventing the mental rehearsal of the observed actions during the delay period. Both orcas copied the model's target actions on command after various delay periods, and crucially, despite the presence of distractor actions. These findings suggest that orcas are capable of selectively retrieving a representation of an observed action to generate a delayed matching response. Moreover, these results lend further support to the proposal that the subjects' performance relied not only on a mental representation of the specific actions that were requested to copy, but also flexibly on the abstract and domain general rule requested by the specific "copy command". Our findings strengthen the view that orcas and other cetaceans are capable of flexible and controlled social learning.
