Incidence of hypopituitarism in adults undergoing radiotherapy for neck and head cancer: protocol for a systematic review and meta-analysis.

INTRODUCTION: When children with head and neck cancer receive radiation therapy as part of their treatment, a considerable frequency of hypopituitarism has been recognised. However, in adults, it has been little studied and it is possible that patients may be inadvertently affected. The objective is to estimate the incidence of anterior pituitary dysfunction in adults undergoing radiotherapy for head and neck cancer. METHODS AND ANALYSIS: A total of five databases will be used to perform the document search: PubMed, Scopus, Web of Science (Core Collection), Ovid-MEDLINE and Embase. Cohort studies will be included without restriction by language or date. The main outcome will be the incidence of adenohypophyseal dysfunction for each axis: prolactin, growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, luteinising hormone and follicle-stimulating hormone. Incidence meta-analysis will be performed using the Freeman-Tukey double arcsine method. In addition, a random-effects model will be used along with a 95% CI. Subgroup analyses will be performed according to tumour location, radiation dose and endocrine assessment time. Meta-regression will be applied according to patient's age and time elapsed until diagnosis. ETHICS AND DISCLOSURE: Since this will be a systematic review of published data, no ethics committee approval is required. The results will be presented at conferences and finally published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42021235163.

Calidad de vida laboral y riesgo de disfunción sexual en enfermeras

Las experiencias y relaciones personales insatisfactorias en el ámbito laboral se asocian a resultados negativos en el aspecto sexual. La disfunción sexual femenina (DSF) es la alteración de cualquiera de las fases del orgasmo. La calidad de vida laboral (CVL) es la percepción del trabajador entre las exigencias del trabajo y las técnicas de afrontamiento. Objetivo: Determinar la asociación entre la calidad de vida laboral y el riesgo de disfunción sexual femenina en enfermeras de un hospital público del Callao, Perú. Método: Estudio observacional, transversal y analítico realizado en enfermeras del Hospital Nacional Daniel Alcides Carrión (HNDAC) de la provincia Constitucional del Callao, Perú. El riesgo de DSF fue medido con la prueba de Rosen. La CVL fue medida con el cuestionario de CVP-35. El análisis estadístico se realizó con el programa STATA versión 15. Se consideró significativo un valor de p<0,05 con un IC de 95%. Resultados: El estudio contó con la participación de 168 enfermeras que respondieron de forma completa. Las dimensiones de CVL asociadas a DSF fueron apoyo directo (p=0,01), motivación intrínseca (p=0,003), la pregunta sobre desconexión de trabajo (p=0,007), el ingreso mensual (p=0,003), el estado civil (p=0,001) y consumo de alcohol (p=0,014). No hubo asociación en el análisis multivariado. Conclusión: En el presente estudio no existió una asociación entre las dimensiones de la calidad de vida laboral y el riesgo de disfunción sexual femenina ajustado por confusores.

Unsatisfactory personal experiences and relationships in the work environment are associated with negative sexual outcomes. Female sexual dysfunction (FSD) is the disturbance of any of the phases of orgasm. Quality of work life (QWL) is the worker's perception between work demands and coping techniques. Objective: To determine the association between quality of work life and the risk of female sexual dysfunction in nurses of a public hospital in Callao, Peru. Methods: Observational, cross-sectional, analytical study conducted in nurses of the Hospital Nacional Daniel Alcides Carrión (HNDAC) of the Constitutional province of Callao, Peru. The risk of FSD was measured with the Rosen test. CVL was measured with the CVP35 questionnaire. Statistical analysis was performed with the STATA version 15 program. A value of p<0.05 with a 95% CI was considered significant. Results: The study involved 168 nurses who responded completely. The dimensions of CVL associated with DSF were direct support (p=0.01), intrinsic motivation (p=0.003), the question on work disconnection (p=0.007), monthly income (p=0.003), marital status (p=0.001) and alcohol consumption (p=0.014). There was no association in the multivariate analysis. Conclusion: In the present study there was no association between dimensions of quality of work life and confounder-adjusted risk of female sexual dysfunction.

Prevalence of Foot At-Risk and its Associated Characteristics among Outpatients with Diabetes Mellitus in a Peruvian Public Hospital.

OBJECTIVE: To assess the prevalence of patients at risk of developing diabetic foot complications(i.e.foot at-risk) and its clinical components according to the updated International Working Group on Diabetic Foot (IWGDF) criteria and to describe demographic and diabetes-related characteristics. METHODS: We conducted a cross-sectional study at María Auxiliadora Hospital between 2017 and 2018. The criteria for foot at-risk in the IWGDF 2019 risk stratification system are classified into four risk categories, R0-R3, ranging from no peripheral arterial disease (PAD) and no peripheral neuropathy (PN) to the presence of PAD or PN in combination with previous foot ulcer, amputation, or end- stage renal disease (R3). According to this system, we obtained prevalence ratios (PR) of foot at-risk categories dependent on sex, age, diabetes duration, and Total Symptom Score. A sample size of 402 subjects was included in the study. RESULTS: Subjects included had a mean age of 61 years, and 66% were female. There were no patients with type 1 diabetes, and 59% percent had a diabetes duration of less than ten years. The prevalence of foot at-risk was 54.3% defined by the IWGDF 2019 criteria, which gave prevalence17% higher than that defined with the previous 1999 criteria. PN and PAD frequency was 37.3% and 30.1%, respectively. Foot at-risk prevalence was 40% higher in those with severe Total Symptom Score (PR 1.40, 95% CI 1.09-1.80) and also 39% higher in men than in women (PR 1.39, 95% CI 1.17-1.64). Likewise, diabetes duration of more than ten years had a 25% higher prevalence of foot at-risk (PR 1.25, 95% CI 1.05-1.49), and those older than 60 years had a 20% higher presence of this condition (PR 1.20, 95% CI 1.0011.43). CONCLUSIONS: Our hospital faces a substantial burden of diabetic foot risk in men, patients with long diabetes duration, and those with painful neuropathy. More initiatives are required at primary or hospital level to detect this critical condition. Likewise, reference centers with multidisciplinary teams to apply prevention and therapeutic interventions are urgently needed.

Association Between the Diabetes mellitus Duration and the Severity of Diabetic Foot Disease in Hospitalized Patients in Latin America.

The objective was to determine the association between a diabetes mellitus duration greater than 10 years and the severity of diabetic foot in hospitalized patients in Latin America.Analytical, observational, and retrospective study based in secondary databases. Patients older than 18 years with diagnosis of diabetes mellitus (DM) and hospitalized for any causes were included. The independent and dependent variables were having more than 10 years of diagnosis of DM and the severity of the diabetic foot disease (Wagner> = 2), respectively. A crude Poisson regression analysis was performed to obtain prevalence rates adjusted to confounders.Male gender was 54.8% and the median age was 62 years. In the group with more than10 years of disease (n = 903) 18% (n = 162) had severe injuries. We performed two Poisson regression analyzes, one of which included the entire sample; and in the other, only patients with some degree of ulcer were included at the time of evaluation (Wagner > = 1). In the first analysis the PR was 1.95 (p < 0.01) adjusted for the significant variables in the bivariate analysis and in the second analysis the PR was 1.18 (p < 0.01) adding to the adjustment the days of injury prior to hospitalization and the location of the ulcer.We conclude that in patients with more than 10 years of diabetes mellitus, diabetic foot injuries are more severe, regardless type of diabetes, gender, age, history of amputation and days of injury prior to hospitalization for inpatients in Latin America.

Asociación entre la necesidad de cuidados paliativos y enfermedades crónicas en pacientes atendidos en un hospital peruano / Association between the need for palliative care and chronic diseases in patients treated in a peruvian hospital

RESUMEN Objetivos. Evaluar la asociación entre las enfermedades crónicas (EC) y la necesidad de cuidados paliativos (NCP). Materiales y métodos. Se realizó un estudio transversal analítico en un hospital peruano durante el 2019. Se incluyó a pacientes hospitalizados con EC y se excluyó gestantes y a los hospitalizados en unidades críticas. En la evaluación de la NCP se aplicó el instrumento SPICT-ESTM, adicionalmente se evaluaron características sociodemográficas y clínicas. La fuerza de asociación se calculó con regresiones de Poisson con varianza robusta para estimar razones de prevalencia crudas (RP) y ajustadas (RPa) por confusores. Resultados. Se evaluó 172 pacientes, la media de edad fue 61 años, donde el 54,7% eran varones y 123 pacientes tenían NCP. En el modelo crudo se encontró asociación con tener enfermedad cerebrovascular (RP: 1,23; p=0,028), cualquier tipo de cáncer (RP: 1,38; p<0,001), cardiopatías (RP: 1,29; p=0,007), nefropatía (RP: 1,42, p<0,001) y enfermedad de Alzheimer (RP: 1,42; p<0,001). La asociación se mantuvo en la mayoría de EC evaluadas en el modelo ajustado, excepto para cardiopatía (RPa: 1,11; p=0,320). La fuerza de asociación fue menor en el caso de diabetes mellitus (RP: 0,78; p=0,044). Conclusión. La NCP en pacientes con enfermedades crónicas hospitalizados es alta y más frecuente en pacientes con cáncer, enfermedad cerebrovascular, problemas renales y enfermedad de Alzheimer. Los programas de cuidado de pacientes con diabetes mellitus pueden disminuir la NCP.

ABSTRACT Objectives. To assess the association between chronic disease (CD) and the need for palliative care (NPC). Materials and methods. An analytical cross-sectional study was carried out in a Peruvian hospital during 2019. Patients hospitalized with CD were included, and pregnant women and those hospitalized in critical units were excluded. The SPICT-ESTM instrument was used to assess the NPC; sociodemographic and clinical characteristics were also evaluated. The strength of association was calculated with Poisson regressions with robust variance to estimate crude prevalence ratios (PR) and adjusted prevalence ratios (aPR) by confounders. Results. A total of 172 patients were evaluated, the mean age was 61 years, where 54.7% were male and 123 patients had NPC. In the crude model, we found an association with having cerebrovascular disease (PR: 1.23; p=0.028), any type of cancer (PR: 1.38; p<0.001), heart disease (PR: 1.29; p=0.007), nephropathy (PR: 1.42, p<0.001) and Alzheimer's disease (PR: 1.42; p<0.001). The association was maintained for most of the evaluated CDs in the adjusted model, except for heart disease (aPR: 1.11; p=0.320). The association strength was lower for diabetes mellitus (PR: 0.78; p=0.044). Conclusion. NPC in hospitalized chronically ill patients is high and more frequent in patients with cancer, cerebrovascular disease, renal problems and Alzheimer's disease. Care programs for patients with diabetes mellitus may decrease NPC.

Clinical and epidemiological characteristics of children with SARS-CoV-2 infection admitted in a Peruvian hospital. / Características clínicas y epidemiológicas de niños con infección por SARS-CoV-2 internados en un hospital peruano.

We carried out an observational, retrospective and descriptive study in order to identify the clinical and epidemiological characteristics of children with SARS-CoV-2 infection admitted to a Peruvian national referral hospital. We included patients from one month old to fourteen years old hospitalized between March and August 2020. A total of 125 patients with SARS-CoV-2 infection were admitted, 18.4% (n = 23) had critical illness and 16.8% (n = 21) had multisystem inflammatory syndrome (MIS-C). The absence of comorbidities and previous history of epidemiological contact were more frequent in patients with MIS-C. Patients in critical condition and patients with MIS-C had lower lymphocyte and platelet counts, and higher C-reactive protein, ferritin and D-dimer values than patients who did not have said conditions. Six (4.8%) out of 125 children died, as well as 3 (13%) children from the group of patients in critical condition. None of the children with MIS-C died.

Con el objetivo de conocer las características clínicas y epidemiológicas de niños con infección por SARS-CoV-2 internados en un hospital peruano de referencia nacional realizamos un estudio observacional, retrospectivo y descriptivo e incluimos pacientes de un mes a catorce años hospitalizados entre marzo a agosto del 2020. Se ingresaron 125 pacientes con infección por SARS-CoV-2, el 18,4% (n = 23) presentaron enfermedad crítica y 16,8% (n = 21) síndrome inflamatorio multisistémico (SIM). En los pacientes con SIM fue más frecuente la ausencia de comorbilidades y el antecedente de contacto epidemiológico. Tanto el grupo en estado crítico como del grupo con SIM, en comparación con los que no tuvieron estas condiciones, presentaron menores recuentos de linfocitos y plaquetas, y mayores valores de proteína C reactiva, ferritina y dímero D. Seis (4,8%) niños de los 125 fallecieron, 3 (13%) del grupo en estado crítico y ninguno del grupo con SIM.

Prevalence and incidence of diabetic peripheral neuropathy in Latin America and the Caribbean: A systematic review and meta-analysis.

AIMS: The objective of this systematic review and meta-analysis is to estimate the prevalence and incidence of diabetic peripheral neuropathy (DPN) in Latin America and the Caribbean (LAC). MATERIALS AND METHODS: We searched MEDLINE, SCOPUS, Web of Science, EMBASE and LILACS databases of published observational studies in LAC up to December 2020. Meta-analyses of proportions were performed using random-effects models using Stata Program 15.1. Heterogeneity was evaluated through sensitivity, subgroup, and meta-regression analyses. Evidence certainty was performed with the GRADE approach. RESULTS: Twenty-nine studies from eight countries were included. The estimated prevalence of DPN was 46.5% (95%CI: 38.0-55.0) with a significant heterogeneity (I2 = 98.2%; p<0.01). Only two studies reported incidence, and the pooled effect size was 13.7% (95%CI: 10.6-17.2). We found an increasing trend of cumulative DPN prevalence over time. The main sources of heterogeneity associated with higher prevalence were diagnosis criteria, higher A1c (%), and inadequate sample size. We judge the included evidence as very low certainty. CONCLUSION: The overall prevalence of DPN is high in LAC with significant heterogeneity between and within countries that could be explained by population type and methodological aspects. Significant gaps (e.g., under-representation of most countries, lack of incidence studies, and heterogenous case definition) were identified. Standardized and population-based studies of DPN in LAC are needed.

Prevalence of Diabetes Mellitus and Its Associated Unfavorable Outcomes in Patients With Acute Respiratory Syndromes Due to Coronaviruses Infection: A Systematic Review and Meta-Analysis.

INTRODUCTION: Only 3 types of coronavirus cause aggressive respiratory disease in humans (MERS-Cov, SARS-Cov-1, and SARS-Cov-2). It has been reported higher infection rates and severe manifestations (ICU admission, need for mechanical ventilation, and death) in patients with comorbidities such as diabetes mellitus (DM). For this reason, this study aimed to determine the prevalence of diabetes comorbidity and its associated unfavorable health outcomes in patients with acute respiratory syndromes for coronavirus disease according to virus types. METHODS: Systematic review of literature in Pubmed/Medline, Scopus, Web of Science, Cochrane, and Scielo until April of 2020. We included cohort and cross-sectional studies with no restriction by language or geographical zone. The selection and extraction were undertaken by 2 reviewers, independently. The study quality was evaluated with Loney's instrument and data were synthesized by random effects model meta-analysis. The heterogeneity was quantified using an I 2 statistic. Funnel plot, Egger, and Begg tests were used to evaluate publication biases, and subgroups and sensitivity analyses were performed. Finally, we used the GRADE approach to assess the evidence certainty (PROSPERO: CRD42020178049). RESULTS: We conducted the pooled analysis of 28 studies (n = 5960). The prevalence analysis according to virus type were 451.9 diabetes cases per 1000 infected patients (95% CI: 356.74-548.78; I 2 = 89.71%) in MERS-Cov; 90.38 per 1000 (95% CI: 67.17-118.38) in SARS-Cov-1; and 100.42 per 1000 (95% CI: 77.85, 125.26 I 2 = 67.94%) in SARS-Cov-2. The mortality rate were 36%, 6%, 10% and for MERS-Cov, SARS-Cov-1, and SARS-Cov-2, respectively. Due to the high risk of bias (75% of studies had very low quality), high heterogeneity (I 2 higher than 60%), and publication bias (for MERS-Cov studies), we down rate the certainty to very low. CONCLUSION: The prevalence of DM in patients with acute respiratory syndrome due to coronaviruses is high, predominantly with MERS-Cov infection. The unfavorable health outcomes are frequent in this subset of patients. Well-powered and population-based studies are needed, including detailed DM clinical profile (such as glycemic control, DM complications, and treatment regimens), comorbidities, and SARS-Cov-2 evolution to reevaluate the worldwide prevalence of this comorbidity and to typify clinical phenotypes with differential risk within the subpopulation of DM patients.

Current knowledge on Hashimoto's encephalopathy: a literature review. / Conocimientos actuales en encefalopatía de Hashimoto: revisión de la literatura.

Hashimoto's encephalopathy is a rare disease, with a reported prevalence of 2.1 per 100 000. Clinical manifestations include confusion, decreased state of consciousness, cognitive deficit, seizures, myoclonus, ataxia, and focal neurological deficits. Due to the wide variety of signs and symptoms, clinical diagnostic suspicion is essential. Diagnosis is based on three pillars: the presence of neurological clinical manifestations after ruling out other causes of encephalopathy. 2) Presence of increased antithyroid antibodies. 3) Significant clinical improvement after the administration of immunomodulation. The treatment of Hashimoto's encephalopathy pursues two objectives: to control the autoimmune process and to control the complications of the disease. Although in most cases recovery is complete with treatment, the risk of relapse can range from 12.5 to 40% in follow-ups to 2 years.

La encefalopatía de Hashimoto es una enfermedad rara. Se reporta una prevalencia de 2,1 por cada 100 000 habitantes. Entre las manifestaciones clínicas se describen confusión, disminución del estado de consciencia, déficit cognitivo, convulsiones, mioclonus, ataxia y/o déficits neurológicos focales. Debido a la amplia variedad de signos y síntomas, la sospecha clínica diagnóstica es fundamental. El diagnóstico se basa en tres pilares: la presencia de manifestaciones clínicas neurológicas, con la exclusión de otras causas de encefalopatía; presencia de anticuerpos antitiroideos aumentados; una mejoría clínica notable luego de la administración de inmunomoduladores. El tratamiento de la encefalopatía de Hashimoto tiene dos objetivos: controlar el proceso autoinmune y controlar las complicaciones de la enfermedad. Aunque en la mayoría de los casos la recuperación es completa con el tratamiento, el riesgo de recaídas puede oscilar entre 12,5 a 40% en seguimientos a dos años.
