We report on the first case of congenital Zika syndrome to be identified during the COVID-19 pandemic in Puerto Rico. The Zika virus (ZIKV) infection was first seen in Puerto Rico in December 2015. It is a flavivirus with vertical transmission, spreading from infected mothers to their fetuses and having a broad spectrum of clinical manifestations, of which microcephaly is the most worrisome. In Puerto Rico, routine ZIKV screening during pregnancy was implemented in October 2016. However, this practice has become less frequent over time...

OBJECTIVE: Hypertension is one of the cardiovascular diseases that causes the most mortality, and 95% of the causes are unknown. The aim of the study was to examine the possible correlation of nesfatin-1 levels, adropin levels, claudin-2 immunoreactivity (claudin-2 expression in the renal proximal tubule), and renalase immunoreactivity (renalase expression in the renal proximal tubule) with arterial blood pressure, kidney function, and kidney damage. METHODS: Adult male Sprague Dawley rats were divided into control and hypertension groups (8 per group)...

OBJECTIVE: This study examined the relationship between resilience, self-efficacy, anxiety, and depression to test whether self-efficacy affected anxiety and depression and compared how the participants in different age groups experienced anxiety, as well as the differences in anxiety between employed and unemployed participants. METHOD: A cross sectional web-based survey study that included adults aged 60 years or older living in Puerto Rico was performed during April and May 2020...

OBJECTIVE: Neonatal abstinence syndrome (NAS) is a set of drug withdrawal symptoms suffered by neonates exposed to drugs in utero. Several studies have widely described NAS incidence and treatment approach; however, little is known regarding the incidence and manifestations of this disease in Puerto Rico (PR). The principal aim of this study was to describe NAS incidence in the neonatal units of hospitals affiliated with the University of PR in terms of occurrence, clinical manifestations, and treatment approaches...

BACKGROUND & OBJECTIVES: Patients with non-alcoholic fatty liver disease (NAFLD) have high prevalences of hypertension (HTN), type 2 diabetes mellitus (T2DM), and cardiovascular disease (CVD), and vice versa. The mechanism of this development is unknown but appears to be related to an underlying metabolic derangement that affects multiple organs. This study aimed to determine the prevalences of these conditions in patients with diagnosed NAFLD. METHODS: Our cohort study aimed to determine the prevalences of HTN, T2DM, and CVD in NAFLD patients registered in the liver database of the University of Puerto Rico School of Medicine; this information is recorded in their medical records...

Of the chronic bacterial infections that affect humans, Helicobacter pylori (H. pylori) infection is one of the most common. It inhabits the stomachs of half of the adult human population. In Puerto Rico, a US territory, it has an overall prevalence of 33%, similar to the prevalence reported in the population of the US as a whole. Helicobacter pylori infection is responsible for mucosal inflammation that may lead to chronic gastritis, most peptic ulcers, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma...

Pet ownership and therapy dogs as companion animals and emotional support have potential health benefits. We report the experiences at a COVID-19 vaccination center after authorizing children's vaccines. When the Pfizer-BioNTech vaccine for children aged 5 to 11 years was authorized for emergency use, we adapted the center's space to receive children, adding cartoon posters and balloons and using children's adhesive bandages, among others. Located at a Campus with six health professional schools, medical students dressed as storybook or movie characters...

OBJECTIVE: During the 2016-2017 Zika virus outbreak in Puerto Rico, the Zika Contraception Access Network (Z-CAN) provided client-centered contraceptive counseling and access to the full range of reversible contraceptive methods at no cost to prevent unintended pregnancies and thereby to reduce Zika-related birth outcomes. METHODS: To understand how Puerto Rican women's perceptions of the Zika virus affected contraceptive decisions and assess how they heard about the Z-CAN program and what influenced their participation, or lack thereof, 24 focus-group discussions were conducted among women of reproductive age who did and did not participate in Z-CAN...

Mucopolysaccharidosis (MPS) is a metabolic disorder resulting from a deficiency of lysosomal enzymes. It is an autosomal recessive disorder with similar incidences in men and women. Mucopolysaccharidosis type IV A is caused by a deficiency of N-acetylgalactosamine-6-sulfatase, which deficiency is, in turn, caused by alterations in the GALNS gene. It is marked by a short stature, a pigeon chest, frontal bossing, kyphosis, and a flat nasal bridge. Intraorally, macroglossia, hypodontia, dentinogenesis imperfecta, a broad mouth, and an anterior open bite are some of the common features...

Extranodal NK/T-cell lymphoma (ENKTL), nasal type and aggressive NK cell leukemia are rare in Western World been less than 1% in USA to 8% in Asia among Non-Hodgkin's lymphomas. It is aggressive, with poor outcome and optimal treatment is unclear. A combination therapy that includes Peg-Asparaginase (SMILE) has been employed in young patients. An 85-year-old Puerto Rican male presented with anorexia, epistaxis, vertigo and involuntary facial movements. He was treated with injectable Onabotulinum toxin A due to suspicion of a hemifacial spasm...

Case of a 44-year-old woman with past medical history of dermatomyositis who had been on Methrotexate therapy who became infected with Legionella pneumophila after staying at a home rental, known commercially as an Airbnb. The patient presented to the ER with complaints of general malaise and subsequently developed sepsis with respiratory failure requiring intubation. CT scan confirmed the diagnosis of pneumonia and through extensive research L. pneumophila was identified using a pneumonia panel that works by identifying nucleic acids of fastidious organisms that are difficult and take long to grow by culture...

Enterocutaneous fistulas can present with significant morbidity and mortality for affected patients, as the abnormal connection can result in exorbitant loss of enteral fluids, electrolyte disturbances, and sepsis, among other complications. We present a patient with a chronic complex enterocutaneous fistula who underwent several surgeries, resulting in a considerable amount of bowel resection. Based on history and findings of high output fistula with diverting transverse colostomy, the fistula was closed with a left rectus myocutaneous pedicle flap to avoid entering the abdominal cavity and prevent the possibility of short bowel syndrome...

OBJECTIVE: There are an estimated 5,570 yearly cancer deaths in Puerto Rico. Breast and colorectal are the most common malignancies among Puerto Rican women. Therefore, prevention and early detection of these cancer types are critical to reducing morbidity and mortality. This study assessed whether women who received the influenza vaccine had increased adherence to cervical, breast, and colorectal cancer screening. METHODS: The Puerto Rico Community Engagement Alliance (PR-CEAL) against COVID-19 Disparities team attended community outreach events throughout Puerto Rico and completed a face-to-face survey among women 18 years or older...

OBJECTIVE: Compare the efficacy of the micro-osteoperforation (MOP) and corticotomy techniques in terms of maxillary canine retraction. METHODS: Thirteen patients (5 females, 8 males; mean age, 18.07 ± 6.74 years) with healthy permanent dentition and requiring the extraction of maxillary first premolars were included in a split-mouth randomized clinical trial. Those subjects with previous orthodontic or endodontic treatment of the canines were excluded. At least 3 months post-extraction, MOPs and corticotomies were performed distal to the canines...

OBJECTIVE: There is no Spanish-language instrument for assessing the self-management strategies used by older adults with physical function disabilities to manage the difficulties that can occur in daily living activities. This study aimed to design and test the content validity of a Spanish version of the newly developed Self-Management of Function in Daily Living Activities Questionnaire (SF-DLAQ). METHODS: A methodological study, guided by the Person-Environment-Occupation-Performance (PEOP) model, was conducted to develop the SF-DLAQ...

OBJECTIVE: According to the literature, depression and tobacco use are closely linked. This study's main objectives were to provide the first population-based epidemiological profile of smokers with depression (SWD) who were 18 years and older and living in Puerto Rico (PR) from 2018 to 2020 and identify any statistically significant differences between SWD and smokers without depression (SWOD). METHODS: A descriptive cross-sectional study was carried out using PR Behavioral Risk Factor Surveillance System (PRBRFSS) data (2018-2020)...

OBJECTIVE: The primary aim of this cross-sectional study was to assess, according to previous cancer diagnosis, the knowledge Puerto Rican women have on the link between obesity-endometrial, -breast, and colon cancer, and determine women's most common source for medical information. METHODS: In this cross-sectional study, eligible female patients (n=234) from the Gynecology and Gynecology-Oncology Clinics completed a self-administered survey from October 2014 to March 2016...

OBJECTIVE: The aim of this study was to determine the expression levels of CDH1, FHIT, and TTPAL genes and to determine the genotype and allele frequencies of the IL7Rα gene polymorphism rs6897932 in patients with breast cancer.

RESULTS: No differences in genotype ratios or allele frequencies were observed between the 2 groups for the IL7Rα gene polymorphism rs6897932...

OBJECTIVE: Breast cancer is a mortal disease that causes many deaths, especially in women. Improved therapies could contribute positively to survival rates. Metabolomics is an important tool for monitoring the alterations of several metabolites in clinical cases. This study aimed to develop a metabolomics model to observe (via mass spectroscopy) metabolic alterations in patients who suffered from breast cancer (BC), both before and after their recovery. MATERIALS AND METHODS: Grades 1 and 2 invasive ductal carcinoma patients were evaluated based on their positron emission tomography/computed tomography results...

Sirtuins (SIRTs) constitute a family of enzyme-type proteins dependent on nicotinamide adenine dinucleotide. These enzymes are considered cellular metabolic sensors since the cell's energy level can regulate their activity to compensate for energy fluctuations. They constitute an evolutionarily conserved family of deacetylases class III enzymes, with a recognized role in prolonging life expectancy. Sirtuins are related to the development of age-associated pathologies, such as cancer, diabetes, neurodegeneration, and metabolic disorders...
