Artículos originales / Probability of anemia in pre-diabetics and diabetics: analytical study carried out in a medical center in Villa el Salvador, Lima-Peru

Resumen Introducción: la organización mundial de la salud estima que 2000 millones de personas padecen anemia, mientras que la pre-diabetes y la diabetes afectan aproximadamente a 352 y 460 millones de personas, respectivamente. La anemia es una complicación frecuente en la diabetes mellitus (DM). Objetivo: evaluar la asociación y probabilidad de alteraciones de la hemoglobina en pre-diabéticos y diabéticos. Metodología: estudio descriptivo, retorspectivo y transversal, la población fue de 1103 pacientes (211 prediabéticos, 223 diabéticos y 669 normoglucémicos), la muestra fue el total de la población que cumplió con los criterios de inclusión y exclusión: adultos normoglucémicos y pre-diabéticos sin presencia de enfermedad aguda o crónica al momento del examen. La asociación entre variables se realizó por medio de la prueba de chi-cuadrado y la probabilidad fue determinada por la prueba de Odds Ratio. Resultados: las mujeres pre-diabéticas tuvieron una probabilidad 1.72 mayor de anemia que mujeres no diabéticas. Los hombres pre-diabéticos tuvieron una probabilidad 2.80 veces mayor de anemia que los no diabéticos. Las mujeres diabéticas tuvieron una probabilidad 2,37 más alta de tener anemia, mientras que los hombres diabéticos tuvieron una probabilidad 4,41 veces más alta que lo hombres no diabéticos de padecer anemia. Conclusiones: pacientes pre-diabéticos tienen mayor probabilidad de anemia que en no diabéticos. Es posible que la hiperglucemia persistente en pre-diabéticos se asocie a cambios en la concentración de esta hemoproteína años antes del desarrollo de diabetes por mecanismos similares, pero de forma incipiente.

Abstract Introduction: The World Health Organization estimates that 2 billion people suffer from anemia, while pre-diabetes and diabetes affect approximately 352 and 460 million people, respectively. Anemia is a frequent complication in diabetes mellitus. Objective: To evaluate the association and probability of hemoglobin alterations in pre-diabetics and diabetics. Methodology: Descriptive, retrospective and cross-sectional study, the population was 1103 patients (211 prediabetics, 223 diabetics and 669 normoglycemics), the sample was the total population that met the inclusion and exclusion criteria: normoglycemic and prediabetic adults without presence of acute or chronic disease at the time of examination. The association between variables was performed using the chi-square test and the probability was determined by the Odds Ratio test. Results: Pre-diabetic women had a 1.72 higher probability of anemia than non-diabetic women. Pre-diabetic men were 2.80 times more likely to have anemia than non-diabetics. Diabetic women were 2.37 times more likely to have anemia, while diabetic men were 4.41 times more likely than non-diabetic men to have anemia. Conclusions: Pre-diabetic patients are more likely to have anemia than non-diabetics. It is possible that persistent hyperglycemia in pre-diabetics is associated with changes in the concentration of this hemoprotein years before the development of diabetes by similar mechanisms, but in an incipient manner.

Asociación y riesgo de hipercolesterolemia en prediabéticos de un centro médico de Villa El Salvador, Lima, Perú / Association and risk of hypercholesterolemia among patients with prediabetes from a medical center in Villa El Salvador, Lima, Peru

RESUMEN Objetivo: Evaluar la asociación y el riesgo de hipercolesterolemia en pacientes adultos prediabéticos atendidos en un centro médico del distrito de Villa El Salvador en Lima, Perú. Materiales y métodos: Estudio analítico, prospectivo y transversal, con datos de historias clínicas de consultas médicas de 749 pacientes atendidos en un policlínico del distrito de Villa El Salvador, Lima, Perú. Se incluyó a pacientes adultos asintomáticos que asistieron a evaluaciones de rutina y preventivas. Se excluyó a pacientes con enfermedades endocrino-metabólicas o en tratamiento con fármacos hipoglucemiantes. Las variables de estudio fueron sexo, hipercolesterolemia y prediabetes. El análisis de asociación se realizó por medio de la prueba de chi cuadrado y el riesgo fue evaluado por medio de la oportunidad relativa; asimismo, se realizó el análisis multivariado por medio de regresión logística binaria y se consideró como punto de corte en decisión de significancia estadística el valor alfa igual a 0,05 y un nivel de confianza de 95 %. Resultados: Hubo asociación estadísticamente significativa entre prediabetes e hipercolesterolemia. Las mujeres prediabéticas tuvieron 1,66 veces más riesgo de desarrollar hipercolesterolemia que las mujeres con niveles de glucosa basal normales, mientras que los hombres con prediabetes tuvieron 2,37 veces más riesgo de tener colesterol alto que los hombres con niveles de glucemia basal normales. Conclusiones: La prediabetes se asocia con la hipercolesterolemia, lo cual aumenta su riesgo. Es justificable realizar la medición conjunta del colesterol total en ayunas junto con la medición de la glucosa basal en campañas preventivo-promocionales de salud y en consultas periódicas, así como durante el seguimiento de pacientes con factores de riesgo de diabetes, prediabetes e hipercolesterolemia, a fin de reducir las consecuencias hemodinámicas y cardiovasculares del colesterol elevado en la sangre y el agravamiento de la morbimortalidad conjunta de la hiperglucemia crónica.

ABSTRACT Objective: To evaluate the association and risk of hypercholesterolemia among adult patients with prediabetes treated at a medical center in the district of Villa El Salvador in Lima, Peru. Materials and methods: An analytical, prospective and cross-sectional study conducted with data from medical consultation records of 749 patients treated at a polyclinic in the district of Villa El Salvador in Lima, Peru. Asymptomatic adult patients who had routine and preventive checkups were included in the research. Patients with endocrine and metabolic disorders or being treated with hypoglycemic drugs were excluded. The study variables were sex, hypercholesterolemia and prediabetes. The association analysis was performed using the chi-square test and the risk was evaluated by means of the odds ratio. In addition, the multivariate analysis was conducted through a binary logistic regression, and an alpha value of 0.05 and a confidence level of 95 % were considered as the cut-off point to determine the statistical significance. Results: There was a statistically significant association between prediabetes and hypercholesterolemia. Females with prediabetes were 1.66 times more likely to develop hypercholesterolemia than females with normal baseline glucose levels, while males with prediabetes were 2.37 times more likely to have high cholesterol than males with normal baseline blood glucose levels. Conclusions: Prediabetes is associated with hypercholesterolemia, thus increasing its risk. It is justifiable to carry out the joint measurement of fasting total cholesterol and baseline glucose in disease prevention and health promotion campaigns, regular checkups and follow-up of patients with risk factors for diabetes, prediabetes and hypercholesterolemia. This helps reduce the hemodynamic and cardiovascular consequences of high cholesterol levels and the worsening of the joint morbidity and mortality of chronic hyperglycemia.

Risk signals mining for Fluocinolone acetonide intravitreal implants based on Hainan Province Franchised Drug Monitoring System and FAERS / 中国药房

OBJECTIVE To explore the risk signals of Fluocinolone acetonide intravitreal implants and promote safe and rational drug use for patients. METHODS Based on the data from the Hainan Province Franchised Drug Adverse Reaction Monitoring Subsystem （hereinafter referred to as the “Franchised Drug Monitoring System”） and the FDA Adverse Event Reporting System （FAERS）， the adverse drug reaction （ADR）/adverse drug event （ADE） reports of Fluocinolone acetonide intravitreal implants were coded by using system organ classification and preferred terminology， and relevant patient information was collected. Risk signal mining was carried out by using the reporting odds ratio （ROR） method and the comprehensive standards method of the UK Medicines and Healthcare Products Regulatory Agency （hereinafter referred to as the “MHRA method”）. RESULTS Among the 72 reports of Fluocinolone acetonide intravitreal implants received by the Franchised Drug Monitoring System， the ratio of male to female was 1∶1.4， the patient’s age was mainly distributed between 18 and 64 years old； ADR/ADE affected 5 systemic organs， with eye organ diseases accounting for 87.7%； among them， there were 9 new and general ADR reports （12.5%） and 4 severe ADR reports （5.6%）； ROR method and MHRA method both identified three risk signals： cataracts， glaucoma， and high intraocular pressure. Among the 244 reports received by the FAERS database， the ratio of male to female was 1∶1.5； ADR/ADE damage affected 10 systemic organs， with 46.1% suffering from various injuries， poisoning， and operational complications， and 32.0% suffering from product problems； there were 20 severe ADR reports （8.2%）； ROR method and MHRA method both identified 19 risk signals， including implantation complications， medication system issues， etc. CONCLUSIONS When using Fluocinolone acetonide intravitreal implants in clinical practice， in addition to paying attention to eye ADR/ADE such as high intraocular pressure， cataracts， and glaucoma， attention should also be paid to the potential risks caused by ADE due to product quality and unreasonable use.

Signal mining and analysis of adverse drug event signals of darolutamide / 中国药房

OBJECTIVE To explore and analyze the adverse drug event （ADE） signals of darolutamide and provide a reference for its clinical safe use. METHODS ADEs related to darotamide were collected based on the US FDA adverse event reporting system （FAERS） database from the third quarter of 2019 to the third quarter of 2022. Data mining and analysis were conducted by the report odds ratio （ROR） and proportional reporting ratio （PRR） methods. RESULTS A total of 565 ADE reports related to darolutamide were extracted， 356 ADE reports about darolutamide as the primary suspected drug were included， 38 ADE signals with darolutamide as the primary suspected drug were excavated， involving 15 system organ class （SOC）， mainly concentrated in patients over 65 years old. The SOC of darotamide ADE signal mainly focused on various examinations， systemic diseases and various reactions at the administration site， benign/malignant tumors or those with unknown nature （including cystic and polypoid）， kidney and urinary system diseases. A total of 13 ADE signals not mentioned in the instructions included increased prostate-specific antigen， dysphagia， cognitive impairment， erectile dysfunction， rhabdomyolysis， gynecomastia and decreased platelet count， etc. CONCLUSIONS When using darolutamide， in addition to ADE in the drug instruction， we should pay close attention to potential ADE， such as increased prostate-specific antigen， rhabdomyolysis， gynecomastia and decreased platelet count， so as to avoid drug withdrawal or organ damage caused by ADE.

Signal Mining Study of Adverse Reaction Associated with Allopurinol and Febuxostat Based on FDA Adverse Events Reporting System(FAERS)Database / 医药导报

Objective To conduct signal mining of adverse events(AEs)of allopurinol and febuxostat based on FAE-RS database,and to explore their potential drug risks and promote rational and safe clinical drug use.Methods The adverse event report data of febuxostat and allopurinol in 22 quarters from the first quarter of 2017 to the second quarter of 2022 were ex-tracted from FAERS database,and the signal mining of febuxostat and allopurinol adverse events(AE)was carried out using ROR method and PRR method.Results There were 5 060 AE reports for allopurinol,concentrated in patients aged≥60 years,in-volving 25 items of system organ classification(SOC),mainly in skin and subcutaneous tissue diseases(40.01%).It was found that 12 SOC categories were not mentioned in the instructions.For febuxostat,there were 905 AE reports,involving 17 SOC items,mainly in cardiac organ diseases(40.17%),and 2 items were not involved in the instructions.Allopurinol and febuxostat were as-sociated with infection and infectious diseases(5.51%,0.49%)and hepatobiliary diseases(5.35%,0.87%),However,these as-sociations were included in the instructions of allopurinol.Allopurinol was associated with the reproductive system and breast dis-eases(0.55%),pregnancy,puerperium and perinatal conditions(0.03%),but febuxostat was not found to be involved in the a-bove SOC.Conclusion The inclusion of adverse reactions in the instructions for allopurinol is relatively inadequate compared to buprostat,and the newly discovered involvement of systemic organs and AE can provide a reference for improving allopurinol in-structions.This study found that allopurinol and febuxostat allopurinol and febuxostat involved system differences,which can pro-vide reference for clinical individualized treatment.

Postoperative Prognostic Nutritional Index and Fibrinogen Could Well Predict Poor Prognosis of Acute Type A Aortic Dissection Patients After Surgery

ABSTRACT Introduction: Inflammatory and immunological factors play pivotal roles in the prognosis of acute type A aortic dissection. We aimed to evaluate the prognostic values of immune-inflammatory parameters in acute type A aortic dissection patients after surgery. Methods: A total of 127 acute type A aortic dissection patients were included. Perioperative clinical data were collected through the hospital's information system. The outcomes studied were delayed extubation, reintubation, and 30-day mortality. Multivariate logistic regression analysis and receiver operating characteristic analysis were used to screen the risk factors of poor prognosis. Results: Of all participants, 94 were male, and mean age was 51.95±11.89 years. The postoperative prognostic nutritional indexes were lower in delayed extubation patients, reintubation patients, and patients who died within 30 days. After multivariate regression analysis, the postoperative prognostic nutritional index was a protective parameter of poor prognosis. The odds ratios (95% confidence interval) of postoperative prognostic nutritional index were 0.898 (0.815, 0.989) for delayed extubation and 0.792 (0.696, 0.901) for 30-day mortality. Low postoperative fibrinogen could also well predict poor clinical outcomes. The odds ratios (95% confidence interval) of postoperative fibrinogen were 0.487 (0.291, 0.813) for delayed extubation, 0.292 (0.124, 0.687) for reintubation, and 0.249 (0.093, 0.669) for 30-day mortality. Conclusion: Postoperative prognostic nutritional index and postoperative fibrinogen could be two promising markers to identify poor prognosis of acute type A aortic dissection patients after surgery.

Nota epidemiológica: razón de ODDS (OR) / Epidemiologic note: ODDS ratio (OR)

Introducción: el Odds Ratio es una medida de efecto para la cual existen diversas traducciones al español. En este documento lo denominaremos OR (Razón de Odds). Es una medida que a través de la historia ha contribuido a establecer asociaciones relevantes para la salud pública. Objetivo: realizar una nota epidemiológica donde se presentan los principales aspectos teórico práctico de la razón de Odds. Metodología: búsquedas en las bases de datos biomédica (Pubmed, Cochrane Library, LILACS), metabuscadores (Google) y a través de la estrategia en bola de nieve y referencias claves. Esta nota metodológica contiene introducción, escenario clínico, desarrollo de concepto, ejemplos, discusión y conclusiones. Resultados: un Odds es el cociente entre la probabilidad de ocurrencia de un evento (p) sobre la probabilidad de que dicho evento no ocurra (1-p). El OR o razón de Odds, es un cociente entre dos Odds. Es una medida del efecto que permite a los investigadores plantear posibles asociaciones entre una exposición y un desenlace. Conclusiones: el OR puede determinarse en diferentes tipos de diseños y por medio del análisis estratificado (método Mantel-Haenszel) y el multivariado utilizando regresión logística, controla variables de confusión.

Introduction: The Odds ratio (OR) is a measure of effect, which has many Spanish equivalents. The term Razón de Odds will be used in this document to designate OR. Throughout history OR has contributed to establish associations in public health. Objective: to conduct an epidemiologic note presenting the main theoretical and practical aspects of Odds ratio. Methodology: a search was conducted in the Pubmed, Cochrane Library and LILACS biomedical databases, Google meta-searchers and through the snowball key references strategy. This methodologic note includes an introduction, clinical scenario, concept development, examples, discussion and conclusions. Results: an Odds is the quotient between the probability of occurrence of an event (p) over the probability of absence of said event (1-p), OR (Odds ratio), is the quotient between two Odds. It is a measure of effect which allows researchers to identify how strongly an exposure is associated with an outcome. Conclusions: OR may be determined using different types of study designs and by means of a stratified analysis (Mantel-Haenszel method) and the multivariate method by logistic regression and control for confounding variables.

Breastfeeding and autism spectrum disorder: case-control study / Transtorno do espectro do autismo e aleitamento materno: estudo de caso controle

Abstract Objectives: to evaluate the association between breastfeeding and Autism Spectrum Disorder (ASD) in children and adolescents. Methods: this is a case-control study carried out in the north of the state of Minas Gerais, Brazil, which included 248 children and adolescents diagnosed with ASD (case group) and 886 children and adolescents without a diagnosis of ASD (control group).Interviews were conducted with the mothers of children and adolescents and a semi-structured questionnaire was used to collect data. For data analysis, a multiple logistic regression model was adopted. The magnitude of associations was estimated by the odds ratio (OR). Three multiple models were fitted: Model 1: presence or absence of breastfeeding; Model 2: duration of breastfeeding; Model 3: duration of exclusive breastfeeding. Results: ASD was associated with the absence of breastfeeding in the three adjusted models: Model 1: OR=2.1, CI95%=1.1-4.1; Model 2: OR=2.3, CI95%=1.2-4.5; Model 3: OR=2.3, CI95%=1.2-4.5. Conclusions: individuals with ASD were more likely to have not received breastfeeding, however, due to the nature of case control studies, it cannot be stated that breastfeeding prevents ASD. Conducting a cohort study may clarify this relationship.

Resumo Objetivos: avaliar a associação entre aleitamento materno e Transtorno do Espectro do Autismo (TEA) em crianças e adolescentes. Métodos: trata-se de um estudo caso-controle realizado no norte de Minas Gerais, Brasil, que incluiu 248 crianças e adolescentes com diagnóstico de TEA (grupo caso) e 886 crianças e adolescentes sem diagnóstico de TEA (grupo controle). Foram realizadas entrevistas com as mães das crianças e adolescentes e utilizado um questionário semiestruturado para coleta dos dados. Para análise dos dados foi adotado modelo de regressão logística múltipla. A magnitude das associações foi estimada pela Odds Ratio (OR). Três modelos múltiplos foram ajustados: Modelo 1: presença ou ausência de aleitamento materno; Modelo 2: duração do aleitamento materno; Modelo 3: duração do aleitamento materno exclusivo. Resultados: o TEA foi associado à ausência de aleitamento materno nos três modelos ajustados: Modelo 1: OR=2,1, IC95%=1,1-4,1; Modelo 2: OR=2,3, IC95%=1,2-4,5; Modelo 3: OR=2,3, IC95%=1,2-4,5. Conclusões: os indivíduos com TEA tiveram maiores chances de não terem recebido aleitamento materno, no entanto, devido à natureza dos estudos de caso-controle, não se pode afirmar que o aleitamento materno previna o TEA. A realização de um estudo de coorte poderá esclarecer essa relação.

Materiales y métodos: Estudio observacional, descriptivo, de casos y controles y retrospectivo basado en datos del Sistema Informático Nacional de Defunciones (Sinadef) del Ministerio de Salud (Minsa) peruano entre enero de 2021 y agosto de 2022. El muestreo fue no probabilístico, intencional por conveniencia según los criterios de inclusión y exclusión. Se incluyó a todos los pacientes con y sin anemia que fallecieron por insuficiencia cardiaca congestiva u otras comorbilidades, que sumaron un total de 35 724 personas. Las variables fueron anemia, definida como un trastorno del tamaño o número de hematíes, de la hemoglobina, así como de la absorción y disponibilidad del hierro, e insuficiencia cardiaca congestiva, definida como la incapacidad del miocardio para bombear sangre de forma competente. Se realizó la prueba de chi al cuadrado y de los coeficientes Phi y V de Cramer para determinar la existencia y grado de asociación de las variables y la razón de probabilidades para la estimación del riesgo. Se consideró un valor de p significativo menor del 0,05, con un intervalo de confianza al 95 %. Resultados: La anemia estuvo moderadamente asociada a la insuficiencia cardiaca congestiva: fallecieron 62,80 % de personas con anemia. Las variables están estadísticamente relacionadas y, según los coeficientes Phi y V de Cramer, se trata de una relación moderada. Se halló que los anémicos tuvieron 11,14 veces mayor riesgo de morir por insuficiencia cardiaca congestiva que las personas con otras comorbilidades. Conclusiones: La anemia se asocia a un alto riesgo de muerte por insuficiencia cardiaca subyacente en la población peruana. Es necesario el seguimiento de los niveles de hierro, hemoglobina y hematíes en pacientes con insuficiencia cardiaca, así como tratar las causas de estas deficiencias, con el objetivo de reducir la morbimortalidad en este grupo de pacientes.

Objective: To determine the risk of death from underlying congestive heart failure among Peruvian patients with anemia. Materials and methods: An observational, descriptive, case-control and retrospective study based on data from the Sistema Informático Nacional de Defunciones (SINADEF National Death Computer System) of the Ministry of Health of Peru (MINSA) and conducted between January 2021 and August 2022. A non-probability purposive convenience sampling was used considering the inclusion and exclusion criteria. All patients with and without anemia who died from congestive heart failure or other comorbidities were included in the research, totaling 35,724 people. The variables were anemia, defined as a condition related to the amount or number of red blood cells and hemoglobin, as well as to iron absorption and availability, and congestive heart failure, defined as the inability of the myocardium to pump blood efficiently. Chi-square test and phi and Cramer's V coefficients were used to determine the presence and degree of association of the variables and the odds ratio for risk estimation. A significant p value less than 0.05 with a 95 % confidence interval was considered. Results: Anemia was moderately associated with congestive heart failure: 62.80 % of people with anemia died from this disease. The variables were statistically related and, according to phi and Cramer's V coefficients, there was a moderate relationship. People with anemia had 11.14 times higher risk of dying from congestive heart failure than people with other comorbidities. Conclusions: Anemia is associated with high risk of death from underlying heart failure in the Peruvian population. It is necessary to monitor iron, hemoglobin and red blood cell levels among patients with heart failure, as well as to identify the causes of these deficiencies in order to reduce morbidity and mortality in this group of patients.

Association of Dietary and Physical Activity Patterns and Hypertension in Western Rajasthan, 2022

Introduction: Hypertension (HTN) is a modifiable risk factor for coronary artery disease, heart failure, cerebrovascular disease and chronic renal failure. HTN affects about 1 billion people globally; by 2025, up to 1.58 billion adults worldwide are likely to suffer from complications of HTN. This study was done to know the diet and physical activity patterns and HTN among the population of three districts of Western Rajasthan. Objectives: To study the dietary and physical activity patterns among the population of Western Rajasthan. and to compare key findings among three districts Pali, Jodhpur and Barmer so that lifestyle changes can be recommended. Methods: A case-control study was done among attendees of NCD clinics of tertiary-level centers in Pali, Barmer and Jodhpur. Hospital Controls were matched to age (± 5 years) and gender Considering the prevalence of HTN to be 20%*, the proportion of exposure in the general population as 0.2, odds ratio to be 2.2, power =80%, alpha=5% sample size is estimated to be 102 cases & 102 controls (from each district). Results: Overall being married (OR= 3.3), having diabetes Cardiac disease (OR= 2.6), excessive salt consumption (OR= 2.7), moderate physical exercise less than 30 minutes (OR=1.9), using oil other than vegetable oil(OR=1.8) , Age >?60 years (OR =1.4) were the key risk factors. It was found that high BMI (BMI>27), consumption of non-vegetable oils (12.7%) was highest in Jodhpur, lack of moderate exercise for at least 30 minutes (81%), lack of sports activity (92%) was highest in Pali, least number of days/week of fruits and vegetables consumption (~1.64 days) was seen in Barmer. Conclusions: Change in quantity of salt consumption and incorporation of moderate physical exercise for >30 minutes was most followed in control of HTN among the attendees of NCD Clinics from the multiple advise given.

ObjectiveTo systematically evaluate the safety of interferon β-1a for treatment of corona virus disease 2019 （COVID-19）， and to provide references for interferon β-1a's clinical application. MethodsThis study was conducted with the database from US Food and Drug Administration adverse event reporting system （FAERS） from January 1， 2015 to March 31， 2021. Information component （IC） and reporting odds ratio （ROR） methods were applied for signal mining. ResultsA total of 463 700 records of COVID-19 were selected for analysis， and 45 positive drug adverse event signals were detected. Headache （IC025=1.09， ROR025=2.28）， pyrexia （IC025=0.51， ROR025=1.51） and multiple sclerosis relapse （IC025=3.67， ROR025=14.71） were positive adverse events with higher frequency. Autoimmune disorder （IC025=4.42， ROR025=24.03）， streptococcal infection （IC025=4.12， ROR025=19.82）， and multiple sclerosis relapse （IC025=3.67， ROR025=14.71） were positive adverse events. Acute lung injury， cardio-respiratory arrest and metabolic acidosis were associated with a higher proportion and frequency of death. ConclusionThere are certain safety issues with interferon β-1a in the treatment of COVID-19， and some adverse events with high frequency and high death rate deserve further attention by medical staffs.

Mining and analysis of ADE signals of romiplostim and eltrombopag based on FAERS database / 中国药房

OBJECTIVE To provide a reference for the safe use of thrombopoietin receptor agonists romiplostim and eltrombopag in clinic. METHODS FDA adverse event reporting system （FAERS） in the United States was adopted to collect adverse drug event （ADE） reports of romiplostim and eltrombopag from their launch in the United States to September 30， 2022； the ADE signals of the two drugs were analyzed using the reporting odds ratio （ROR） method and the comprehensive standard method of the UK Medicines and Healthcare Products Regulatory Agency. RESULTS A total of 14 021 and 4 431 ADE reports were collected about romiplostim and eltrombopag， respectively， with a gender composition of more females than males. After signal screening， 563 ADE signals were obtained about romiplostim， involving 25 system organ classes （SOC）； eltrombopag had 433 ADE signals， involving 26 SOC. The most frequently reported ADE for both drugs was platelet count decreased （2 060， 1 585 cases）， which was mentioned in their drug instructions. In terms of signal intensity， romiplostim exhibited the highest signal for abnormal thrombopoietin levels （ROR of 2 268.85）， while eltrombopag had the highest signal for positive dengue virus test （ROR of 954.50）， with neither of these signals mentioned in their respective drug instructions. CONCLUSIONS The ADE of romiplostim and eltrombopag mainly affects the blood and lymphatic system， and there are many new suspicious high-risk signals.

Study Design: Observational Studies

Observational study designs are those where the investigator/researcher just observes and does not carry out any intervention(s)/actions to alter the outcome. The three most common types of observational studies are cross-sectional, case control and cohort (or longitudinal). In cross-sectional studies, both the exposure/risk factor(s) and the outcome(s) are determined at a single time point. They can provide information on prevalence of a condition and snapshot of probable associations that can be used to generate hypothesis. Case-control studies are where subjects are selected based on presence/absence of outcome and the risk factors are determined during the study after enrolment of study subjects. The association between exposure and outcome is reported as odds ratio. These studies; however, have high risk of bias, which must be taken care of during study design. Cohort studies are prospective in nature, where subjects are selected based on presence/absence of exposure, and the outcome(s) is determined at the end of study. These studies can provide incidence of disease/outcome and the association between exposure and outcome is reported as relative risk. They are useful to ascertain causality. High dropouts of study participants and confounding can be problems encountered in these studies. Keywords: Case-control, Cohort, Cross-sectional, Odds ratio, Relative risk, Survey

A Review on Logistic Regression in Medical Research

In today抯 scenarios many healthcare decisions are being taken by predictive modeling and machine learning techniques. With this review, we focused on logistic regression model, a kind of predictive modeling used in machine learning, and how healthcare researchers take decisions by the help of predictive modeling. For a better data analysis in healthcare, we need to understand the concept of logistic regression as well as others terms, which are linked with it. so that we can clearly understand the concept behind it and implement in medical research. In this review we worked on an example and illustrated how to perform logistic regression using R programming language. The aim of this paper is to understand logistic regression in healthcare and implement it for decision making.

OBJECTIVE To exc avate and evaluate the adverse reaction signals of 4 kinds of imported programmed cell death 1 （PD-1）and its ligand （PD-L1）inhibitors，and to guide rational drug use in clinic. METHODS OpenVigil 2.1 software was used to obtain the adverse event reports of four drugs as nivolumab ，pembrolizumab，atezolizumab and durvalumab from the first quarter of 2013 to the fourth quarter of 2020 in the US FDA adverse event reporting system. The reporting odds ratio and proportional reporting ratio were used for signal mining to evaluate new or potential adverse reaction signals. RESULTS A total of 46 840 reports of adverse events with PD- 1/PD-L1 inhibitors as the primary suspected drug were collected ，including 28 896 reports of nivolumab，13 298 reports of pembrolizumab ，3 398 reports of atezolizumab ，and 1 248 reports of durvalumab. From the general characteristics of these reports ，the gender distribution was more men than women ，and the age distribution was mainly in the range of 51-85 years old. The reporting year was mainly in the nearly 4-5 years，and the main reporting countries were the US and Japan，with“death”and“hospitalization or prolonged hospitalization ”as the main serious adverse events which were over 50％ of the whole of 4 kinds of adverse events. A total of 1 597 adverse reaction signals were obtained ，involving 26 systems，focusing on “benign，malignant and unspecified neoplasms （cystic and polypoid tumor ）”，“infections and infestations ”and“investigations”， etc. The analysis of the top 50 adverse reaction signals showed that the largest number of report was endocrine system disease ，the most frequency signal was “malignant neoplasm progression ”and the strongest adverse reaction signal was “radiation pneumonitis ”. And it was also found that 13 adverse reaction signals ，such as “radiation pneumonitis ”“cholangitis”“fulminant type 1 diabetes mellitus” “blood creatine phosphokinase increased ” “disseminated intravascular coagulation ”“cardiac failure ”and “cerebral infarction ”，etc.，were not reported in the drug instructions. CONCLUSIONS PD-1/PD-L1 inhibitors mediate a large number of adverse reaction signals，resulting in high safety risks in “benign，malignant and unspecified neoplasms （cystic and polypoid tumor ）”，“infections and infestations ”and “investigations”，etc. The newly discovered 13 adverse reaction signals ，such as “radiation pneumonitis ”“cholangitis”“blood creatine phosphokinase increased ”“cardiac failure ”and“cerebral infarction ”are of great significance for guiding rational drug use in clinic.

Categorical Analysis on Mental Health Status of the people of Kerala during the COVID-19 Pandemic using the Proportional Odds Model

Background: Covid-19 pandemic forced people to get confined to social isolation and maintain social distancing which affected their mental health. The study aims at understanding the impact on the mental health status of people in Kerala, based on their demographic profile and the psychological issues faced during the Covid-19 lockdown. Methodology: The study included 700 respondents from various districts of Kerala telephonic and mailed questionnaires for the period of December 2020 - May 2021. Ordered logit model is used for the econometric analysis using R software. Results: The overall mental health status of an individual is affected by various reasons which are taken as various categories for the analysis. As a result of log odds estimated, Covid-19 patients are more disposed to mental health issues. Male respondents had a positive impact on mental health issues and unmarried people of all gender are disturbed with lockdown distress. Almost all occupational categories taken into account are more or less shaken with the pandemic except those with proper job security including Government and PSU workforces.

Extracorporeal Membrane Oxygenation-Related Nosocomial Infection after Cardiac Surgery in Adult Patients

Abstract Introduction: The evaluation of extracorporeal membrane oxygenation-related nosocomial infection (ECMO-related NI) in a homogeneous cohort remains scarce. This study analyzed ECMO-related NI in adult patients who have undergone cardiac surgery. Methods: From January 2012 to December 2017, 322 adult patients who have received ECMO support after cardiac surgery were divided into the infection group (n=131) and the non-infection group (n=191). ECMO-related NI was evaluated according to demographic data, surgical procedures, and ECMO parameters. Results: The incidence of ECMO-related NI was 85.4 cases per 1000 ECMO days. Acinetobacter baumannii was the most common pathogen causing blood stream infection and respiratory tract infection. Prolonged duration of surgery (P=0.042) and cardiopulmonary bypass assist (P=0.044) increased the risk of ECMO-related NI. Body mass index (odds ratio [OR]: 1.077; 95% confidence interval [CI]: 1.004-1.156; P=0.039) and duration of ECMO support (OR: 1.006; 95% CI: 1.003-1.009; P=0.0001) were the independent risk factors for ECMO-related NI. Duration of ECMO support > 144 hours (OR: 2.460; 95% CI: 1.155-7.238; P<0.0001) and ECMO-related NI (OR: 3.726; 95% CI: 1.274-10.895; P=0.016) increased significantly the risk of in-hospital death. Conclusion: Prolonged duration of ECMO support was an independent risk factor for NI. Surgical correcting latent causes of cardiopulmonary failure and shortening duration of ECMO whenever possible would reduce susceptibility to NI.
