The Prevalence of Internet Use as a Source of Information Among Patients With Hypertension.

Background and objective The incidence of hypertension is growing at an alarming rate globally. In the United States, nearly half of the adult population suffers from hypertension, a disease potentially associated with long-term dire consequences and comorbidities. While Internet access has proliferated, and free Internet-based education resources for healthy lifestyles have exponentially increased over the past two decades, little is known about whether Internet-based information can be or is used as a self-learning tool for hypertension management in a community setting. With almost no published data, if and to what degree Internet-based, self-directed learning tools are used for hypertension management needs to be assessed. In light of this, we aimed to evaluate the prevalence of Internet use as a source of information in patients with known diagnoses of hypertension who presented to our Internal Medicine clinic at Texas Tech University Health Sciences Center, El Paso. Materials and methods We conducted a single-center, cohort-based observational study at our teaching hospital's internal medicine clinic. A survey questionnaire was distributed to all adults aged more than 18 years with a known diagnosis of hypertension. Consent for participation was obtained from all participants. Of the total studied population, 93.6% (190/203) were of Hispanic descent. Moreover, 67.5% (137/203) identified as female. Of note, 22.7% (46/203) reported using the Internet to learn about hypertension. Internet users were younger, with a mean age of 61.4 years compared to 68.7 (p=0.02) years for non-Internet users, attended institutions of a higher grade of education, and mostly received information regarding hypertension from their families (91.3% vs 2.5%, p<0.001). While most patients used the Internet for making treatment decisions and were satisfied with their choices, more than a quarter felt confused and anxious after using Internet-based resources. Results Most patients in the study were found to not use the Internet as a resource tool for hypertension management (157/203; 77.3%). Among the 22.7% of patients who used the Internet for hypertension management, the most commonly utilized resource was Google.com, as an initial step to hypertension research (26/46, 58.6%, p<0.001), followed by multiple resources within a predetermined list on the provided survey (14/46, 30.4%). The survey also assessed the reasons for using Internet-based resources, with the primary reason being evaluating treatment options (19/46, 41.5%), followed by developing coping skills (13/46, 28.2%), and lastly aiding in decision-making (10/46, 21.5%). Conclusions Internet-based educational tools are mushrooming as the Internet is becoming more pervasive. This study shows that within this predominant Hispanic population, nearly one-quarter of patients with hypertension are using Internet-based, self-learning tools. This highlights a slow shift in medical education which providers have to be prepared for as patients will be using these tools as secondary information sources for medical decision-making more frequently going forward. Further studies need to be conducted to evaluate the current and longitudinal impact of these new information sources.

Insights Into Differences in Pulmonary Hemodynamics in Hispanic Patients With Pulmonary Arterial Hypertension.

Background: Emerging data suggest that Hispanic patients with pulmonary arterial hypertension (PAH) exhibit improved survival rates compared to individuals of other ethnicities with similar baseline hemodynamics. However, the underlying reasons for this survival advantage remain unclear. This study focused on comparing pulmonary hemodynamics in Hispanic and non-Hispanic PAH patients and how these differences may contribute to varied clinical outcomes. Methods: A retrospective analysis of right heart catheterization data was conducted on a treatment-naive PAH patient cohort from a single center. Results: Over a 10-year period, a total of 226 PAH patients were identified, of which 138 (61%) were Hispanic and 88 (39%) were non-Hispanic. Hispanic patients presented with lower pulmonary artery pressures, lower pulmonary vascular resistance, and exhibited significantly higher pulmonary arterial compliance (PAc). Hispanic patients had better 5-year survival rates. Conclusions: This study highlights the importance of exploring phenotypic differences in ethnically diverse PAH cohorts.

Evaluation of Four Validated Risk Scores to Predict Outcomes in Hispanic Patients With Acute Pulmonary Embolism.

Risk stratification plays an essential role in the management of acute pulmonary embolism (PE). Several risk scores have been studied to support risk stratification and management. While ethnic differences in acute PE risk factors exist, current risk scores lack validation for Hispanic patients. Therefore, the present study retrospectively investigated the performance of the pulmonary embolism severity index (PESI), simplified PESI (sPESI), the European Society of Cardiology risk assessment (ESC), and the Bova score, to predict 30-day mortality in Hispanic patients presenting with an acute PE. Among 437 patients admitted with acute PE, 30-day mortality was 10.8%; 30-day mortality in low-risk groups ranged from 0% (sPESI, ESC) to 0.2% (PESI, Bova), and 3.0% (Bova) to 5.7% (PESI) in the highest risk groups, respectively. All four scores produced statistically significant discrimination between different risk strata. However, no single scoring system was able to identify all patients with 30-day mortality. The findings of the present study suggest that PESI, sPESI, ESC, and Bova scores provide important information about 30-day mortality in Hispanic in-patients presenting with acute PE. However, additional clinical information could further improve predictability that is not provided by a single scoring system.

Inflammatory Myositis Following Statin Use in a Patient With Untreated Hypothyroidism.

Inflammatory myositis (IM) presents a diagnostic challenge due to its multifaceted etiology and varying clinical presentations. This case involves a 55-year-old male with asymptomatic hypothyroidism, recent statin use, and rapidly progressing proximal muscle weakness. He presented with profound weakness in the upper and lower extremities, severely impairing his daily activities. The patient's medical history included recent hospitalizations for idiopathic interstitial lung disease, myopericarditis, and pneumonia, adding complexity to his condition. Laboratory findings revealed elevated serum muscle enzymes, notably creatine kinase, indicating muscle damage and rhabdomyolysis. Serological testing confirmed the absence of myositis-specific antibodies and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies. The patient was eventually diagnosed with IM and rhabdomyolysis, likely secondary to statin use or hypothyroidism. Treatment with methylprednisolone, levothyroxine, and discontinuation of atorvastatin led to rapid improvements in AST levels and overall muscle strength. This case highlights the challenges of managing IM and emphasizes the importance of assessing thyroid function before initiating lipid-lowering therapy.

Superior Mesenteric Artery Syndrome in Systemic Lupus Erythematosus.

Although the gastrointestinal (GI) manifestations of systemic lupus erythematosus (SLE) are relatively less reported, they are common and occur in approximately half of individuals with SLE. These symptoms vary and include, but are not limited to, oral ulceration, dysphagia, nausea, vomiting, diarrhea, abdominal pain, and intestinal perforation. Gastrointestinal manifestations are often triggered by an inciting event, such as an infection or the side effects of medication. This case report presents a rare GI-related SLE complication, namely superior mesenteric artery syndrome.

Prevalence and clinical significance of deep vein thrombosis in Hispanic patients with acute pulmonary embolism.

The prevalence of concomitant deep vein thrombosis (DVT) and its impact on 30-day outcomes in Hispanic patients with acute pulmonary embolism (PE) is unknown. We retrospectively studied a cohort of Hispanic patients admitted for acute PE to determine the relationship of concomitant DVT to clot burden on chest computer tomography (CT), right heart strain, and 30-day mortality. We identified 391 patients admitted with acute PE; 168 (42.9%) had concomitant DVTs on admission; 39 patients (9.9%) died during the 30-day follow-up: 12 patients without concomitant DVT and 27 with concomitant DVT, respectively (p < .001). The presence of a proximal DVT independently predicted 30-day mortality even after adjusting for age, gender and admission PE severity index scores (PESI) (hazard ratio [HR] 2.0; 95% confidence interval [CI]: 1.4-3.0, p = .001). Proximal DVTs remained a significant predictor of 30-day mortality in patients with low and intermediate PESI scores (HR 2.5; 95% CI: 1.1-6.0, p = .035). The prevalence of concomitant DVT in Hispanic patients presenting with acute DVT is relatively lower than other ethnic groups. However, a proximal location of a DVT is of significant prognostic relevance. Hispanic patients with acute PE should routinely undergo compression doppler ultrasonography (CDUS) of the lower extremities.

Coccidioides-Induced Pyopneumothorax in an Immunocompetent Patient.

Coccidioidomycosis is a rare infection caused by the dimorphic fungi Coccidiodes immitus or Coccidioides posadasii. This fungal infection is very common in the American Southwest as well as northern Mexico. Though the fungus is ubiquitous, symptomatic coccidioidomycosis usually occurs in the elderly or immunocompromised. This case report discusses a unique instance of an immunocompetent 29-year-old male without any notable past medical history who was found to have a coccidioidal cavitary lung lesion with concomitant pyopneumothorax.

Homeless Patient With Community-Acquired Methicillin-Resistant Staphylococcus aureus Brain Abscesses.

Brain abscess secondary to community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infection is a rare, yet highly fatal disease. This article presents the case of a 45-year-old homeless female with a medical history of bipolar disorder, seizure disorder, and substance use disorder who was admitted with altered mental status. Laboratory tests on admission revealed neutrophil-predominant leukocytosis, elevated inflammatory markers (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP]), and lactic acid. MRI brain demonstrated multiple cerebral abscesses with surrounding edema and sagittal vein thrombosis. The patient was initiated on broad-spectrum antibiotics and underwent a right-sided minimally invasive needle biopsy of the abscess and left frontal craniotomy for abscess evacuation, the culture of which confirmed the diagnosis of MRSA infection. As the patient did not have any hospitalization or procedure in the recent past, a diagnosis of CA-MRSA was made. The patient's clinical status improved following the procedure and antibiotic administration, but she left against medical advice before completing treatment. This case highlights the importance of early recognition and aggressive management of CA-MRSA infections, especially in vulnerable populations such as the homeless.

Terbinafine-Induced Liver Injury: A Case Report.

Hepatic injuries attributable to terbinafine usage are a well-documented yet infrequent phenomenon. This case study details the clinical presentation and management of a 70-year-old Hispanic female, with no previous medical history, subsequently hospitalized for progressive jaundice, right upper quadrant abdominal discomfort, and worsening pruritus. A comprehensive review of her prior records revealed a recent terbinafine prescription for onychomycosis, which she took consistently for five weeks and then self-discontinued four weeks before her current admission. Laboratory tests on admission revealed a cholestatic pattern of liver injury, evident by transaminitis and conjugated hyperbilirubinemia. The R factor used to determine whether a liver injury is hepatocellular or cholestatic was 0.9. Further diagnostic imaging, including abdominal ultrasound, CT of the abdomen, and magnetic resonance cholangiopancreatography, failed to disclose an obstructive pathology, revealing only cholelithiasis and chronic cholecystitis. Therapeutically, the patient was initiated on hydroxyzine to address symptoms of pruritus, and then subsequently underwent a liver biopsy. Histopathologic findings from the biopsy revealed benign hepatic parenchyma demonstrating focal canalicular cholestasis, mild chronic inflammation involving select portal tracts, and chronic lobular inflammation, suggesting terbinafine-induced hepatotoxicity. This case highlights the challenges of diagnosing terbinafine-induced liver injury, emphasizing the need for a high index of clinical suspicion and recognizing the potential for prolonged symptomatic manifestation after drug discontinuation. This article provides valuable insights into the complexities inherent in such diagnoses and significantly enriches a medical provider's approach to diagnosing and treating unexplained liver injuries.

A direct capture method for purification and detection of viral nucleic acid enables epidemiological surveillance of SARS-CoV-2.

Studies have demonstrated that SARS-CoV-2 RNA can be detected in the feces of infected individuals. This finding spurred investigation into using wastewater-based epidemiology (WBE) to monitor SARS-CoV-2 RNA and track the appearance and spread of COVID-19 in communities. SARS-CoV-2 is present at low levels in wastewater, making sample concentration a prerequisite for sensitive detection and utility in WBE. Whereas common methods for isolating viral genetic material are biased toward intact virus isolation, it is likely that a relatively low percentage of the total SARS-CoV-2 RNA genome in wastewater is contained within intact virions. Therefore, we hypothesized that a direct unbiased total nucleic acid(TNA) extraction method could overcome the cumbersome protocols, variability and low recovery rates associated with the former methods. This led to development of a simple, rapid, and modular alternative to existing purification methods. In an initial concentration step, chaotropic agents are added to raw sewage allowing binding of nucleic acid from free nucleoprotein complexes, partially intact, and intact virions to a silica matrix. The eluted nucleic acid is then purified using manual or semi-automated methods. RT-qPCR enzyme mixes were formulated that demonstrate substantial inhibitor resistance. In addition, multiplexed probe-based RT-qPCR assays detecting the N1, N2 (nucleocapsid) and E (envelope) gene fragments of SARS-CoV-2 were developed. The RT-qPCR assays also contain primers and probes to detect Pepper Mild Mottle Virus (PMMoV), a fecal indicator RNA virus present in wastewater, and an exogenous control RNA to measure effects of RT-qPCR inhibitors. Using this workflow, we monitored wastewater samples from three wastewater treatment plants (WWTP) in Dane County, Wisconsin. We also successfully sequenced a subset of samples to ensure compatibility with a SARS-CoV-2 amplicon panel and demonstrated the potential for SARS-CoV-2 variant detection. Data obtained here underscore the potential for wastewater surveillance of SARS-CoV-2 and other infectious agents in communities.
