Structural Study of Anxiety and Mood-related Symptomatology in Psychiatric Outpatients.

Introduction: Knowledge of the symptomatological structure of mental disorders is relevant for their understanding and classification. In the absence of previous Latin American research on the simultaneous structural exploration of various types of psychiatric symptomatologies, the objective of this study is to examine the structure of anxious and mood-related symptoms, resulting syndromes, and their correlations.

Method: Several instruments for the evaluation of anxious, depressive, and manic symptoms were administered to 305 psychiatric outpatients.

Successful management of hepatitis B and C coinfection: a case report.

We report the case of a patient with chronic hepatitis B and C managed with direct-acting antivirals in an outpatient setting. Chronic hepatitis B was first treated with entecavir before initiating treatment for chronic hepatitis C. The patient achieved viral suppression for hepatitis B and sustained virological response for hepatitis C.

Progression of HTLV-1 Associated Myelopathy/Tropical Spastic Paraparesis after Pregnancy: A Case Series and Review of the Literature.

HTLV-1-associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) is a progressive non-remitting and incapacitating disease more frequently seen in women and with a patchy worldwide distribution. HAM/TSP develops in a small percentage of HTLV-1-infected individuals during their lifetime and etiologic factors for disease progression are still unclear. This study aims to describe the first case series of the progression of HAM/TSP in relation to pregnancy.

Medical conditions, symptoms of anxiety, and depression during the COVID-19 pandemic in a population sample of Lima, Peru.

Introduction: This study aims to determine differences between the number of underlying medical conditions, depression, and anxiety, when controlling for the covariates of age, sex, and completed education.

Methods: Participants (n = 484) indicated the number of medical conditions present during the survey, also including the PHQ-9 and GAD-7, to assess depression and anxiety, respectively.

Results: Differences were found between groups of medical conditions and the combined values of PHQ-9 and GAD-7 after controlling for the covariates mentioned above (F = 5.

Risk factors for pulmonary tuberculosis recurrence, relapse and reinfection: a systematic review and meta-analysis.

Background: The rate of pulmonary tuberculosis (TB) recurrence is substantial. Identifying risk factors can support the development of prevention strategies.

Methods: We retrieved studies published between 1 January 1980 and 31 December 2022 that assessed factors associated with undifferentiated TB recurrence, relapse or reinfection.

Waldenström's Macroglobulinemia and Cryoglobulinemic Glomerulonephritis: An Unusual Case of Monoclonal Gammopathy of Renal Significance.

Cryoglobulins are immunoglobulins that precipitate at temperatures below 37 °C and dissolve upon reheating. They can induce small-vessel vasculitis with renal involvement. Cryoglobulinemic glomerulonephritis is a rare manifestation that occurs in patients with monoclonal gammopathy, specifically Waldenström's macroglobulinemia.

Streptococcus pneumoniae serotype 19A in hospitalized children with invasive pneumococcal disease after the introduction of conjugated vaccines in Lima, Peru.

Background: The Pneumococcal conjugate vaccine (PCV) has decreased cases of invasive pneumococcal disease (IPD) worldwide. However, the impact of PCVs introduction may be affected by the serotype distribution in a specific context.

Methods: Cross-sectional multicenter passive surveillance study of IPD cases in pediatric patients hospitalized in Lima, Peru between 2016 and 2019 (after PCV13 introduction) to determine the serotype distribution and antimicrobial resistance of Streptococcus pneumoniae.

Antibiotic point prevalence survey and antimicrobial resistance in hospitalized patients across Peruvian reference hospitals.

Background: Peru reports higher levels than other countries in Latin America of resistance to antimicrobials among Gram-positive and Gram-negative bacteria, however data on antibiotic use in Peru are scarce. This study aims to estimate the prevalence and quality of antibiotic prescription in hospitalized patients and to determine the antibiotic susceptibility rates of bacteria causing key bacterial infections.

Methods: We carried out a point prevalence survey of antibiotic prescription at ten public hospitals in nine regions of Peru.

Tuberculosis Knowledge among Persons Living with HIV Attending a Tertiary Hospital in Lima, Peru.

Tuberculosis (TB) is the leading cause of death among people living with HIV (PLWH). Limited TB knowledge has been associated with delayed TB diagnosis and low adherence to TB treatment. A cross-sectional study was conducted among PLWH at the largest HIV-referral center in Lima, Peru, to describe TB knowledge among PLWH and potential associated sociodemographic factors.

Methicillin-Resistant Staphylococcus aureus Bloodstream Infections in Hospitalized Patients in Peru.

There is a knowledge gap in the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) causing bloodstream infections (BSIs) in Peru. Through a surveillance study in 13 hospitals of 10 Peruvian regions (2017-2019), we assessed the proportion of MRSA among S. aureus BSIs as well as the molecular typing of the isolates.

Healthcare personnel in 2016-2019 prospective cohort infrequently got vaccinated, worked while ill, and frequently used antibiotics rather than antivirals against viral influenza illnesses.

Background: Uncertainty about risk of illness and the value of influenza vaccines negatively affects vaccine uptake among persons targeted for influenza vaccination.

Methods: During 2016-2019, we followed a cohort of healthcare personnel (HCP) targeted for free-of-charge influenza vaccination in five Lima hospitals to quantify risk of influenza, workplace presenteeism (coming to work despite illness), and absenteeism (taking time off from work because of illness). The HCP who developed acute respiratory illnesses (ARI) (≥1 of acute cough, runny nose, body aches, or feverishness) were tested for influenza using reverse-transcription polymerase chain reaction (rt-PCR).

Socio-Demographic, Clinical, and Mortality Differences between HIV-Infected and HIV/HTLV-1 Co-Infected Patients in Peru.

Background And Aims: In Peru, the estimated prevalence of human immunodeficiency virus (HIV) and human T-lymphotropic virus-1 (HTLV-1) co-infection has been reported to be as high as 18%. Despite the endemicity of HTLV-1 in Peru, few studies have assessed the impact of HIV/HTLV-1 co-infection. Our study compared socio-demographic and clinical characteristics, and mortality rates between HIV-infected and HIV/HTLV-1 co-infected patients.

[Cardiac arrhythmias and amyloidosis].

Cardiac amyloidosis (CA) is a form of cardiomyopathy characterized by the extracellular deposit of protein fibers in the myocardium, leading to the development of heart failure, arrhythmias, and electrical conduction system alterations. It is known that most cardiomyopathies have a close relationship with heart rhythm abnormalities, however, CA is specially related to different kinds of arrhythmias even in pre-diagnosis stages. Arrhythmias like atrial fibrillation are present in up to 70% of patients with CA associated with a high risk of cardioembolic complications independent of the risk stratification.

[Cardiovascular complications in pregnant woman with Primary Mediastinal B-Cell Lymphoma].

A 26-year-old pregnant woman with 29 weeks of gestational age reported two months of cough, dyspnea, orthopnea, and palpitations. Chest tomography revealed a 10x12cm solid mass in the right lung. Echocardiography showed that the tumor compromised the right atrium and ventricle, and was diagnosed by transcutaneous biopsy as Primary Mediastinal B-Cell Lymphoma (PMCBL).

[Pneumobilia, pneumoperitoneum and pneumowirsung of traumatic etiology: Case report and review of the literature].

Pneumobilia is a phenomenon associated with the presence of a biliary-enteric fistula or manipulation of the bile duct during procedures or surgical interventions that cause dysfunction of the sphincter of Oddi. A known, but infrequently reported event, is the increase in intraabdominal pressure after closed abdominal trauma, which causes pneumobilia due to a mechanism of retrograde air leakage towards the bile duct. Depending on the general compromise of each patient, the prognosis can vary from a benign condition that only requires conservative management, to being life threatening.

[Use of the Scottish and Newcastle Anti-Emetic Pretreatment (SNAP) scheme in recovery from massive overdose of acetaminophen poisoning with acute liver failure - Case report].

Acetaminophen is a drug widely used in the world and easily accessible due to its antipyretic, analgesics characteristics, among others (1); however, exposure to toxic doses causes organic damage and even death. We present the case of an 18-year-old female patient who ingested 40 grams of acetaminophen and developed severe liver dysfunction, being treated with N-acetylcysteine (NAC) antidotal therapy according to the simplified scheme: Scottish and Newcastle Anti-emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presenting improvement in the clinical course and decrease in liver profiles, coagulation disorder, INR and resolution of the condition.
