Mental Health and Other Factors Associated with COVID-19 Vaccination Intention toward Children of Military Parents in Lambayeque, Peru.

There is evidence that vaccine acceptability is strongly associated with mental health. However, no studies assessing intention to vaccinate (ITV) intention toward children of military parents have been documented. The current research aimed to establish the prevalence and factors of ITV children against COVID-19 in military parents in Lambayeque-Peru, 2021. Analysis was conducted with the dependent variable ITV children reported by military parents. The independent variables were history of mental health, searching for mental health support, food insecurity, resilience, anxiety, depression, burnout, posttraumatic stress, and suicidal risk. Prevalence ratios and 95% confidence intervals were estimated. Of 201 military personnel evaluated, 92.5% were male, 82.5% were of the Catholic faith, and the median age was 40.9% of respondents reported seeking mental health help during the COVID-19 pandemic. It was reported anxiety (20.3%), depression (6.5%), and posttraumatic stress disorder (6.5%). Most reported ITV in children against COVID-19 (93%). In the multiple models, we found that Catholics had a 23% higher prevalence of ITV in the children where PR = prevalence ratios and CI = confidence intervals (PR = 1.23; 95% CI: 1.01-1.50). Likewise, seeking mental health support increased the prevalence of ITV by 8% (PR = 1.08; 95% CI: 1.00-1.15). Seeking mental health support and belonging to the Catholic faith had a higher ITV of children of Peruvian military personnel. Finding mental health support, experiencing burnout syndrome, having a relative who suffers from mental health problems, and being part of the Catholic religion were associated with a higher willingness to immunize the children of Peruvian military members.

Risk Factors for Depression Among Middle-Aged to Older People Living With HIV in Lima, Peru.

INTRODUCTION: Depression is prevalent among aging people living with HIV (PLWH) worldwide. We sought to identify depression risk factors among a group of middle-aged and older PLWH in Lima, Peru. MATERIALS AND METHODS: We assessed risk factors for depression among PLWH over age 40 receiving care in an HIV clinic in Lima, Peru. The Patient Health Questionnaire-9 (PHQ-9) was administered. We performed descriptive statistics and logistic regression analyses. RESULTS: Mean age was 51.7 ± 7.7 years with 15.3% females. One-quarter of participants had depression with higher frequency in females. Risk factors that significantly increased the risk of depression included female sex (adjusted prevalence ratio [aPR] = 2.19 [95%CI 1.07-4.49]), currently smoking (aPR = 2.25 [95%CI 1.15-4.43]), and prior opportunistic infection (aPR = 2.24 [95%CI 1.05-4.76]). DISCUSSION: Our study demonstrates that PLWH who are female, current smokers, or had an opportunistic infection have higher risk of depression. Identifying PLWH at-risk for depression is key to early mental health interventions.

Resilience, sleep quality and sleepiness in Peruvian medical students: a multicenter study.

Background: Resilience can mitigate the negative impact produced by the COVID-19 pandemic. Medical students endure significant academic stress, so adjusting to sudden changes can present greater mental health challenges. The aim is to identify the level and prevalence of resilience and to know what are the educational variables and is sleep quality associated with resilience. Methods: A cross-sectional study was conducted using an online questionnaire. The survey was elaborated in Google Forms and shared through social networks. The outcome was resilience, measured with the Connor Davidson Resilience Scale. Its association was assessed with sleep quality (measured with the Pittsburgh Sleep Quality Index), daytime sleepiness (measured with the Epworth Sleepiness Scale), and selected academic/sociodemographic variables. Generalized linear models were used to identify the association between the variables. Results: Of 1277 participants, 35.7% experienced high resilience. Poor sleep quality and sleepiness were present in 88.4% and 36.0% of students, respectively. High resilience was associated with good sleep quality (PR:1.56; 95%CI: 1.34 - 1.83; p-value<0.001), absent sleepiness (PR:1.59; 95%CI: 1.32-1.91; p-value<0.001), male sex (PR: 1.21; 95%CI: 1.05-1.39; p-value 0.006), working (PR:1.14), having family responsibilities (PR: 1.36; 95%CI: 1.09-1.70; p-value 0.005) and spending more than 6 hours studying (PR: 1.35; 95%CI: 1.17-1.54; p-value<0.001). Conclusion: 4 out of 10 students presented high levels of resilience. The development of resilience depended on multiple individual and sociodemographic factors. These findings are important to support universities in developing resilience-building measures and strategies that can be implemented to mitigate the adverse pandemic event.

Seroinfection of Antibodies to Toxoplasma gondii, Parvovirus B19, Treponema pallidum, and HIV in a Pregnant Attending a Medical Center in Northern Peru.

Introduction: Transplacental infections are frequent, especially in developing countries, where limited screening is performed to find infectious agents in the pregnant population. We aim to determine the clinical and epidemiological characteristics and seroinfection of antibodies against Toxoplasma, parvovirus B19, T. pallidum, and HIV in pregnant women who attended the Motupe Health Center in Lambayeque, Peru during July-August 2018. Methods: A descriptive cross-sectional study was conducted in 179 pregnant women interviewed with a standardized questionnaire. ELISA was used to determine antibodies to Toxoplasma and parvovirus B19. The detection of syphilis and HIV was conducted using immunochromatography, while the detection of hepatitis B was conducted using FTA-ABS and immunofluorescence, respectively. Results: Of 179 pregnant women, syphilis and HIV infections routinely included in the screening of pregnant women presented a seroinfection of 2.2 and 0.6%, respectively. Toxoplasmosis seroinfection was 25.1%, while IgM antiparvovirus B19 was 40.8%, revealing that pregnant women had an active infection at the time of study. Conclusion: The level of seroinfection of toxoplasmosis reveals the risk to which pregnant women who participated in the study are exposed. The high seroinfection of parvovirus B19 could explain the cases of spontaneous abortion and levels of anemia in newborn that have been reported in Motupe, Lambayeque, Peru. However, future causality studies are necessary to determine the significance of these findings.

Cerebral hemodynamics and optic nerve sheath diameter acquired via neurosonology in critical patients with severe coronavirus disease: experience of a national referral hospital in Peru.

Aim: We aimed to describe the neurosonological findings related to cerebral hemodynamics acquired using transcranial Doppler and to determine the frequency of elevated ICP by optic nerve sheath diameter (ONSD) measurement in patients with severe coronavirus disease (COVID-19) hospitalized in the intensive care unit of a national referral hospital in Peru. Methods: We included a retrospective cohort of adult patients hospitalized with severe COVID-19 and acute respiratory failure within the first 7 days of mechanical ventilation under deep sedoanalgesia, with or without neuromuscular blockade who underwent ocular ultrasound and transcranial Doppler. We determine the frequency of elevated ICP by measuring the diameter of the optic nerve sheath, choosing as best cut-off value a diameter equal to or >5.8 mm. We also determine the frequency of sonographic patterns obtained by transcranial Doppler. Through insonation of the middle cerebral artery. Likewise, we evaluated the associations of clinical, mechanical ventilator, and arterial blood gas variables with ONSD ≥5.8 mm and pulsatility index (PI) ≥1.1. We also evaluated the associations of hemodynamic findings and ONSD with mortality the effect size was estimated using Poisson regression models with robust variance. Results: This study included 142 patients. The mean age was 51.39 ± 13.3 years, and 78.9% of patients were male. Vasopressors were used in 45.1% of patients, and mean arterial pressure was 81.87 ± 10.64 mmHg. The mean partial pressure of carbon dioxide (PaCO2) was elevated (54.08 ± 16.01 mmHg). Elevated intracranial pressure was seen in 83.1% of patients, as estimated based on ONSD ≥5.8 mm. A mortality rate of 16.2% was reported. In the multivariate analysis, age was associated with elevated ONSD (risk ratio [RR] = 1.07). PaCO2 was a protective factor (RR = 0.64) in the cases of PI ≥ 1.1. In the mortality analysis, the mean velocity was a risk factor for mortality (RR = 1.15). Conclusions: A high rate of intracranial hypertension was reported, with ONSD measurement being the most reliable method for estimation. The increase in ICP measured by ONSD in patients with severe COVID-19 on mechanical ventilation is not associated to hypercapnia or elevated intrathoracic pressures derived from protective mechanical ventilation.

Factors associated with intention to be vaccinated with the COVID-19 booster dose: a cross-sectional study in Peru.

Introduction: The pandemic of COVID-19 continues to impact people worldwide, with more than 755 million confirmed cases and more than 6.8 million reported deaths. Although two types of treatment, antiviral and immunomodulatory therapy, have been approved to date, vaccination has been the best method to control the spread of the disease. Objective: To explore factors associated with the intention to be vaccinated with the COVID-19 booster dose in Peru. Material and Methods: Cross-sectional study, using virtual and physical surveys of adults with two or more doses of COVID-19 vaccine, where the dependent variable was the intention to be vaccinated (IBV) with the booster dose. We calculated prevalence ratios with 95% confidence intervals, using generalized linear models of the Poisson family with robust varying, determining associations between sociodemographic, clinical, and booster dose perception variables. Results: Data from 924 adults were analyzed. The IBV of the booster doses was 88.1%. A higher prevalence was associated with being male (aPR = 1.05; 95% CI [1.01-1.10]), having a good perception of efficacy and protective effect (PR = 3.69; 95% CI [2.57-5.30]) and belonging to the health sector (PR = 1.10; 95% CI [1.04-1.16]). There was greater acceptance of the recommendation of physicians and other health professionals (aPR = 1.40; 95% CI [1.27-1.55]). Conclusions: Factors associated with higher IBV with booster dose include male gender, health sciences, physician recommendation, and good perception of efficacy.

Short-Term Adverse Effects of the Fourth Dose of Vaccination against COVID-19 in Adults over 40 Years of Age.

Booster vaccines are a strategy to mitigate the conditions in the health, social, and economic fields that the COVID-19 pandemic has brought. A series of adverse effects have been observed since the first vaccination. The present investigation aims to describe the short-term adverse effects of the fourth dose against COVID-19 in adults older than 40 from a region of Peru. The study population was over 40 years of age at the COVID-19 vaccination center in Trujillo, Peru. A 21-day follow-up was conducted from vaccination with the fourth dose, considering sex, age, body mass index, comorbidities, history of COVID-19 infection, vaccination schedule, and simultaneous vaccination against influenza as variables of interest. Multinomial logistic regression with robust variance was used to estimate the risk ratio (RR). In total, 411 people were recruited, and it was found that 86.9% of the participants presented adverse effects after injection with the fourth dose of the vaccine against COVID-19. Pain at the injection site was the most reported symptom after 3 days. Assessment of adverse effects after 3 days found that age ≥ 60 years was associated with a lower likelihood of adverse effects compared to those younger than 60 years (RRc: 0.32; 95% CI: 0.0.18-0.59), males compared to females were associated with a lower likelihood of adverse effects (RRc: 0.54; 95% CI 0.30-0.98), being overweight (RRc: 2.34; 95% CI: 1.12-4.89), and last vaccine with Pfizer-BioN-Tech (RRc: 0.42; 95% CI: 0.18-0.96). Associated adverse effects are mild to moderate. Injection site pain and general malaise are the most frequent adverse effects.

Prevalence and factors associated with fear of COVID-19 in military personnel during the second epidemic wave in Peru.

Introduction: During the COVID-19 pandemic, the mounting workload and heightened stress may contribute to exacerbated mental health challenges, including an increased fear of COVID-19, among military personnel. Despite the potential influence of these factors, there remains a scarcity of studies addressing mental health issues, particularly the fear of COVID-19, within this specific population. We aimed to determine the prevalence and factors associated with fear of COVID-19 among military members. Methods: A cross-sectional study was conducted between November 2 and 9, 2021, during the second wave of the COVID-19 pandemic in the Lambayeque region, Peru. The outcome variable was fear of COVID-19, assessed using the Fear of COVID-19 Scale. The association with resilience (Connor-Davidson Resilience Scale, abbreviated as CD-RISC), food insecurity (Household Food Insecurity Access Scale, abbreviated as HFIAS), physical activity (International Physical Activity Questionnaire-Short Form, abbreviated as IPAQ-S), eating disorder (Eating Attitudes Test-26, abbreviated as EAT-26), and other socio- demographic variables was assessed. Results: Among the 525 participants, the median age was 22, 95.8% were male, and 19.2% experienced fear of COVID-19. A higher prevalence of fear of COVID-19 was associated with age (PR=1.03; 95% CI: 1.01-1.06), religion (PR=2.05; 95% CI: 1.04-4.05), eating disorder (PR=2.95; 95% CI: 1.99-4.36), and having a relative with mental disorder (PR=2.13; 95% CI: 1.09-4.17). Overweight (PR=0.58; 95% CI: 0.37-0.90) and a high level of resilience (PR=0.63; 95% CI: 0.43-0.93) were associated with a lower prevalence of fear of COVID-19. Discussion: Two out of ten military personnel were afraid of COVID-19. Our results highlight the need for targeted interventions addressing the factors contributing to fear of COVID-19 among military personnel, emphasizing the significance of mental health support and preventive measures within this specific population.

Laboratory biomarkers associated with COVID-19 mortality among inpatients in a Peruvian referral hospital.

Aim: To evaluate the biochemical and hematological markers associated with the risk of death due to COVID-19 in a clinical cohort with a severe clinical profile. Methods: A retrospective study was conducted among 215 anonymized inpatient records from the Hospital Nacional Almanzor Aguinaga Asenjo, Peru, between April and June 2020. The association between biomarkers and death due to COVID-19 was assessed using Cox regression, with a multivariable modeling of 1) biochemical and 2) hematological markers. Kaplan-Meier analyses and time-dependent receiver operating characteristic curves were calculated for each associated biomarker (p < 0.05). Results: Data analysis of 215 inpatient records revealed an overall mortality rate of 51.30% (95% CI 44.70-58.50), a mean age of 63.90 ± 14.10 years, and a median oxygen saturation of 88% (interquartile range 82-92%). The best-fitted biochemical model included higher levels of C-reactive protein (CRP), D-dimer, fibrinogen, urea, and lactate dehydrogenase. Similarly, the best-fitted hematological model included higher absolute neutrophil and prothrombin time, and lower absolute platelet counts. The best area under the curve values in both models were found to be CRP and D-dimer values (>0.74) and the absolute neutrophil count (0.63). Conclusions: Some specific biochemical markers outperformed hematological markers. Evaluated hematological counts analyzed in multivariable models proved to be better markers and could be useful to discriminate COVID-19 patients at high risk of death.

The role of angiogenesis inhibitors associated with tyrosine kinase inhibitors in the first-line treatment for EGFR-mutated advanced lung cancer.

Tyrosine kinase inhibitors (TKIs) are the standard treatment for epidermal growth factor receptor mutant (EGFRm) advanced non-small cell lung cancer (NSCLC). Combining TKIs with an angiogenesis inhibitor has shown promise in pre-clinical studies. A systematic search of clinical trials found that combining erlotinib (a first-generation TKI) with bevacizumab or ramucirumab (angiogenesis inhibitors) improved progression-free survival (PFS) in EGFRm advanced NSCLC patients compared to TKI alone. However, no significant benefit in overall survival (OS) was observed in trials. Similar efficacy was seen in patients with specific EGFR mutations. Third generation TKIs were used as second-line therapy for patients with the T790M mutation. The combination treatment was associated with a higher incidence of severe adverse events. Overall, combining erlotinib or another TKI with an angiogenesis inhibitor is a safe and effective alternative for first-line treatment in EGFRm advanced NSCLC, particularly in countries without access to osimertinib and for patients with the EGFR L858R mutation.

Serum and cerebrospinal fluid neurofilament light chains measured by SIMOA™, Ella™, and Lumipulse™ in multiple sclerosis naïve patients.

BACKGROUND: Neurofilament light chains (NfL) are cytoskeletal biomarkers of axonal damage, about 40-fold higher in cerebrospinal fluid (CSF) compared to serum, and requiring ultrasensitive techniques to be measured in this latter fluid. OBJECTIVES: To compare CSF and serum NfL levels in multiple sclerosis (MS) patients using different platforms. METHODS: 60 newly diagnosed relapsing-remitting MS patients (38 females; median age: 36.5 years, range: 15-60) were enrolled before steroid or disease-modifying treatments. CSF and serum NfL were measured with: the commercial Ella™ microfluidic platform (Bio-Techne), the Lumipulse™ Chemiluminescent Enzyme ImmunoAssay (Fujirebio), and the SIMOA™ on the SR-X instrument using NF-light assays (Quanterix). RESULTS: CSF and serum NfL absolute levels strongly correlated between assays, although being more elevated with Ella™. Passing-Bablok regression showed high agreement in measuring CSF NfL between assays (with greater proportional difference using Ella™), and very high agreement for serum comparing SIMOA™ and Lumipulse™. Similarly, the Bland-Altman comparison evidenced lower biases for Lumipulse™ for both fluids. CONCLUSIONS: CSF and serum NfL in naïve MS patients are reliably measured with all assays. Although not interchangeable, SIMOA™ and Lumipulse™ showed high agreement for serum and CSF values.

Utilidad diagnóstica de citopatología para diagnóstico de nódulos tiroideos malignos en un hospital peruano / Diagnostic utility of cytopathology for the diagnosis of malignant thyroid nodules in a Peruvian hospital

RESUMEN Objetivos: determinar el rendimiento diagnóstico de la biopsia por punción aspiración con aguja fina (PAAF) para el diagnóstico de nódulos tiroideos malignos. Materiales y métodos: estudio retrospectivo que evaluó las PAAF de tiroides realizadas en el Hospital Nacional Guillermo Almenara Irigoyen en Lima, Perú, durante un período de tres años. Se categorizó el diagnóstico citopatológico de las biopsias usando el sistema de Bethesda, se consideró las categorías V y VI como malignas y la categoría II como benigna. Se obtuvo solo una biopsia por paciente y se consideró el resultado con la categoría de Bethesda más alta. Todos los pacientes fueron sometidos a tiroidectomía y los resultados histopatológicos se categorizaron como malignos o benignos. Resultados: se incluyó a 173 pacientes con resultados citopatológicos de Bethesda II al VI. El diagnóstico citológico mostró que el 47,4% de los pacientes tenían Bethesda VI. El 59,5% de los nódulos tiroideos fueron malignos en la histopatología, siendo el carcinoma papilar el tipo más frecuente. El rendimiento diagnóstico de la PAAF fue alta cuando considera Bethesda V y VI como malignos, con una sensibilidad 91,92%, especificidad 71,67%, valor predictivo positivo 84,26%, valor predictivo negativo 84,31% y precisión de 84,28%, razón de verosimilitud positiva 3,39; pero mejoró significativamente cuando se consideró solo Bethesda VI como maligno, con sensibilidad del 90,7%, especificidad del 89,58%, precisión 90,3% y razón de verosimilitud positiva 8,71. Conclusiones : la PAAF tiene buen rendimiento. Este estudio demostró ser de gran utilidad en nuestro centro de salud para detectar errores y promover mejoras, así también como modelo para próximas investigaciones en diferentes establecimientos de salud.

ABSTRACT Objectives: To determine the diagnostic performance of fine needle aspiration biopsy (FNAB) for diagnosing malignant thyroid nodules. Methods: This is a retrospective study that assessed thyroid FNABs in Guillermo Almenara-Irigoyen National Hospital in Lima, Peru, during a three-year period. Cytopathologic diagnosis of biopsies was categorized using the Bethesda System, considering categories V and VI as malignant, and category II as benign. A single biopsy per patient was obtained, and results with the highest value in the Bethesda System were considered. All patients underwent thyroidectomy and histopathological results were characterized as malignant or benign. Results: One hundred and seventy-three patients were included in the study. Their cytopathology results were Bethesda II to VI. Cytological diagnosis showed that 47.4% of all patients were Bethesda VI. Nearly sixty percent (59.5%) of thyroid nodules were malignant in histopathology, and papillary carcinoma was the most frequent neoplasm. Diagnostic performance of FNAB was high when considering Bethesda V and VI as malignant, with 91.92% sensitivity, 71.67% specificity, 84.26 positive predictive value, 84.31% negative predictive value, and 84.28% precision. Positive verisimilitude rate was 3.39; but this significantly improved when only Bethesda VI was considered as malignant, with 90.7% sensitivity, 89.58% specificity, 90.3% precision, and 8.71 positive verisimilitude rate. Conclusion: FNAB showed good performance. This study proved to be quite useful in our healthcare facility for detecting errors and promote improvement, as well as a model for future research in different healthcare instances.

Use of PD-1 blockade in refractory/relapsed natural killer T-cell lymphomas: a systematic review and synthesis of case reports.

Natural killer/T-cell lymphoma (NK/T-cellL) is an aggressive non-Hodgkin's lymphoma with limited treatment options for patients who experience disease progression or recurrence after second-line treatment. The use of new therapies, such as pembrolizumab, which involves immune checkpoint blockade mechanisms, is proposed. This systematic review followed the MOSE guidelines and searched PUBMED/MEDLINE, EMBASE, and Scopus databases. Fourteen articles were found, reporting on the use of pembrolizumab anti PD-1 in NK/T-cellL patients. The objective response rate was 84.50%, with disease-free survival ranging from two to 48 months. The complete response rate was 61.6%, and the quality of the reported studies was evaluated to be of high and moderate confidence bias levels in case reports and high bias in clinical trials. Pembrolizumab and others anti PD-1 are treatment options for refractory/recurrent NK/T-cellL, regardless of PD-L1 expression, with good short- and long-term results and low adverse events.

Nurses' Environmental Practices in Northern Peruvian Hospitals.

BACKGROUND: Decreasing emissions of the global healthcare sector will be an important tool for decreasing the magnitude of climate change. The environmental practices of nurses can have a positive environmental impact. The purpose of this study is to identify environmental practices performed by nurses while at work and home along with their associated factors. METHODS: This study is a cross-sectional descriptive study conducted by surveying nurses from two public hospitals in Lambayeque, Peru. We utilized the Nurses' Environmental Awareness Tool to collect information about nurses' knowledge on environmental impacts, their risk to health, and environmental behaviors at both work and home. RESULTS: Of the 106 participants who responded, the average age was 41 years, and 29 (28%) worked in surgical services. A little more than half of nurses reported appropriate energy use (51%) and recycling (53%) at work, while 94 (89%) implemented environmental biosafety. There was an observed association between age and years of employment with appropriate energy use, recycling, implementation of environmental biosafety, appropriate chemical substance use, and preventing medication waste. CONCLUSION: Nurses reported a favorable tendency toward adequate environmental practices at work and at home. However, more studies are needed to identify the factors that increase nurses' use of these practices. APPLICATIONS TO PRACTICE: As one of the most trusted professions, professional nurses have an opportunity to play a pivotal role in promoting environmental health and practices in both the workplace and their personal lives. This study highlights areas of potential intervention in the workplace to develop and promote appropriate environmental practices by nurses to decrease pollution by the healthcare sector.

Depression, anxiety, and stress in medical students in Peru: a cross-sectional study.

Objective: To determine the prevalence and factors associated with depressive, anxious, and stress symptoms in medical students in Peru, during the second pandemic wave of COVID-19. Methods: We conducted an analytical cross-sectional study in 405 medical students from a university in northern Peru. The DASS-21 instrument was used to evaluate mental health outcomes (depression, anxiety, and stress), and to investigate their association with socio-educational characteristics. Results: We found a prevalence of depressive, anxious, and stress symptoms of 71.6% (95% CI: 66.94-75.95), 71.9% (95% CI: 67.2-76.2), and 62.7% (95% CI: 57.8-67.4); respectively. Students with eating behavior disorders had a higher prevalence of depressive symptoms (PR: 1.35), anxious symptoms (PR: 1.27), and stress symptoms (PR: 1.31). The prevalence of depressive symptoms (PR: 1.57), anxious symptoms (PR: 1.27), and stress symptoms (PR: 1.24) increased in students who did not report regular physical activity. In addition, having almost always academic exhaustion increased the prevalence of depressive symptoms (PR: 1.46), stress symptoms (PR: 1.72). On the contrary, the prevalence of depressive symptoms (PR: 0.79), anxious symptoms (PR: 0.73) and stress symptoms (PR: 0.82) decreased in male students. Students who reported sleeping 8 or more hours daily had a lower prevalence of stress symptoms (PR: 0.82). Conclusion: Symptoms of depression and anxiety occurred in 7 out of 10 students, and stress in 6 out of 10. Among the factors associated with the presence of anxiety, depression, and stress were eating behavior disorder and not regularly exercising. Periodic evaluations of mental symptomatology are required and counseling should be promoted in medical schools.

Association between receiving information on obstetric complications and institutional delivery: An analysis of the demographic and health survey of Peru, 2019.

Objective: To evaluate the association between receiving information on obstetric complications and institutional delivery in Peruvian women in 2019. Methods: We conducted a secondary analysis of the 2019 Peruvian Demographic and Family Health Survey (ENDES) database. The dependent variable was the type of delivery (institutional or non-institutional). The exposure variable was self-reporting of having received information on obstetric complications during prenatal care. The association of interest was evaluated using binary logistic regression models, obtaining crude odds ratios (cOR) and adjusted odds ratios (aOR) with their respective 95 % confidence intervals (95%CI). Values of p < 0.05 were considered statistically significant. Results: We included a total of 14,835 women in the analysis. Of the total, 14,088 (94.1 %) reported having received information on pregnancy complications. Also, 13,883 (92.5 %) had an institutional delivery in their last pregnancy. The adjusted model showed that women who reported knowing the complications that can occur in pregnancy had a higher probability of presenting an institutional delivery (aOR = 1.47; 95%CI: 1.04-2.08). Conclusions: Receiving information about pregnancy complications was found to be associated with a higher probability of institutional delivery. Ensuring the provision of information to the pregnant woman about pregnancy complications can be a useful strategy to increase institutional delivery.

Evidence-based indications for ivermectin in parasitic diseases: An integrated approach to context and challenges in Peru.

Ivermectin has emerged as a therapeutic option for various parasitic diseases, including strongyloidiasis, scabies, lice infestations, gnathostomiasis, and myiasis. This study comprehensively reviews the evidence-based indications for ivermectin in treating parasitic diseases, considering the unique context and challenges in Peru. Fourteen studies were selected from a systematic search of scientific evidence on ivermectin in PubMed, from 2010 to July 2022. The optimal dosage of ivermectin for treating onchocerciasis, strongyloidiasis, and enterobiasis ranges from 150 to 200 µg/kg, while lymphatic filariasis requires a higher dose of 400 µg/kg (Brown et al., 2000). However, increased dosages have been associated with a higher incidence of ocular adverse events. Scientific evidence shows that ivermectin can be safely and effectively administered to children weighing less than 15 kg. Systematic reviews and meta-analyses provide strong support for the efficacy and safety of ivermectin in combating parasitic infections. Ivermectin has proven to be an effective treatment for various parasitic diseases, including intestinal parasites, ectoparasites, filariasis, and onchocerciasis. Dosages ranging from 200 µg/kg to 400 µg/kg are generally safe, with adjustments made according to the specific pathology, patient age, and weight/height. Given Peru's prevailing social and environmental conditions, the high burden of intestinal parasites and ectoparasites in the country underscores the importance of ivermectin in addressing these health challenges.

Food insecurity in Piura, Peru, in the context of post-earthquake and the COVID-19 pandemic.

Introduction: Piura, located in a seismic zone, faces challenges related to food security. The aim of this study was to analyze aspects related to food insecurity in the region following the 6.1-magnitude earthquake that occurred in 2021, within the context of the COVID-19 pandemic. Methods: A secondary analysis was performed in 177 people exposed to the earthquake in Piura. Food insecurity was assessed with the Household Food Insecurity Access Scale. Its association with insomnia, resilience, anxiety/depressive symptoms, and general variables were determined using generalized linear models. Results: Food insecurity was observed in 31.1% (95% CI: 24.3-38.4) of participants. This prevalence was higher in people with mild (PR: 1.73, 95% CI: 1.12-2.70) and moderate (PR: 1.55, 95% CI: 1.09-2.22) anxiety symptoms, severe depressive symptoms (PR: 2.74, 95% CI: 1.24-6.03), and previous exposure to the El Niño Phenomenon (PR: 1.72; 95% CI: 1.06-2.81). An income higher than 5000 Peruvian soles (approximately 1300 US dollars) was associated with a lower prevalence of food insecurity (PR: 0.22, 95% CI: 0.13-0.40). Conclusions: Overall, three out of 10 individuals experienced food insecurity after the 2021 earthquake in Piura. Food insecurity may be aggravated by mental disorders, previous exposure to the El Niño phenomenon, and the COVID-19 pandemic. Our study contributes to the field by exploring a range of variables related to food insecurity in a unique context: post-earthquake and during the COVID-19 health emergency in Peru. These findings enhance our understanding of food insecurity at the regional level and highlight the need for preventive food security programs in seismic events.

Association between Love Breakup and Suicidal Ideation in Peruvian Medical Students: A Cross-Sectional Study during the COVID-19 Pandemic.

Objective: We aimed to determine the association between a major romantic breakup and suicidal ideation in medical students from three universities in Peru. Methods: A cross-sectional study was conducted during the first pandemic wave in 2021 on medical students from three universities in northern Peru. The outcome was suicidal ideation, measured with question nine of the PHQ-9. The exposure was the experience of a major love breakup during the pandemic. In addition, its association with other covariates (age, sex, family members infected with COVID-19, deceased family members with COVID-19, insomnia, and anxiety, among others) was examined. Results and discussions: Out of 370 students, 19.5% reported a major love breakup during the pandemic (95%CI: 15.5-23.8), and 34.3% had suicidal ideation (95%CI: 29.4-39.4). Having a major love breakup was associated with a higher prevalence of suicidal ideation (PR: 1.49, 95%CI: 1.32-1.67). Moderate insomnia (PR: 2.56, 95%CI: 1.70-3.87) and anxiety symptoms (PR: 1.94, 1.10-3.44) were also associated with suicidal ideation. Conclusion: Our study provides evidence of a significant association between a major love breakup and suicidal ideation. This finding emphasizes the need for further research to better understand this association and inform the development of effective suicide prevention policies in medical education.

Fatal leukodystrophy in Costello syndrome: a case report.

BACKGROUND: Costello syndrome (CS) is a rare genetic condition characterized by dysregulation of the signaling pathway, phenotypic alteration due to fetal macrosomia or growth retardation, facial abnormalities, loose skin, cardiovascular abnormalities, and a variable degree of intellectual disability. CASE PRESENTATION: We describe the case of a 20-month-old male patient with fetal macrosomia and polyhydramnios, presenting psychomotor development delay and growth limitation during the first months of life. CS was diagnosed at four months of age after detecting a variant of the HRAS gene c.35G > C (p.G12A). A clinical description of his condition was recorded throughout his life, including cardiovascular diseases, endocrine disorders, and recurrent infections. At 20 months of age, after presenting events of marked hypotonia and generalized seizures, brain magnetic resonance revealed symmetrical lesions of the infra- and supratentorial white matter in both cerebral hemispheres, which resulted in the diagnosis of cerebral leukodystrophy. The patient had a rapid and progressive deterioration that eventually led to death. CONCLUSIONS: This is the first report of a case of CS in Peru. In addition, this is a case that presented with multisystemic conditions culminating in leukodystrophy, which is a rare event according to the literature.
