RESUMEN

Statins are the first line of treatment for both primary and secondary prevention of atherosclerotic cardiovascular disease. Despite the positive effects of statins on cardiovascular events, not all patients can use them at an optimized dose. The reason for this is the skeletal muscle side effects, termed statin-associated muscle symptoms (SAMS). Despite extensive research, the precise pathophysiology of SAMS remains unclear and multiple mechanisms may contribute to this phenomenon. Various therapeutic options are available for the management of SAMS, ranging from rechallenging with the same or a different statin to utilizing non-statin therapeutic alternatives in patients intolerant to statins. However, the lack of consensus on the definition of SAMS, the absence of a definitive diagnostic test, and lack of a universally accepted management algorithm pose a great challenge in dealing with this entity. This review aims to explore the various pathophysiological mechanisms involved in SAMS and understand the difference between self-limited toxic myopathy and immune-mediated myopathy requiring immunomodulatory therapy. The conundrum of statin withdrawal, tapering, and rechallenge in SAMS will also be explored in detail along with the newer non-statin therapies that are available.

RESUMEN

Background Inflammatory bowel disease (IBD), comprising ulcerative colitis and Crohn's disease gives rise to chronic intestinal inflammation. Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by joint and systemic inflammation. IBD is often linked with various autoimmune diseases, with RA being one of the most common. The coexistence of IBD and RA results in an increased inflammatory state, significantly compromising quality of life. Understanding the epidemiological and clinical characteristics of IBD patients with RA is essential for optimizing their management and improving outcomes. Methodology This retrospective observational study utilized data from the National Inpatient Sample (NIS) database from 2016 to 2020. Patients aged 18 years and older with a primary discharge diagnosis of IBD were included. This population was subdivided into two groups based on the presence and absence of RA. The primary objective was to compare outcomes between hospitalized IBD patients with and without RA. Key outcomes assessed included mortality rates, hospital length of stay (LOS), and total hospital charges. Secondary outcomes included the prevalence of comorbidities and IBD-related complications. Results From 2016 to 2020, a total of 455,655 hospitalized IBD patients were identified, among whom 10,590 (2.32%) had an underlying diagnosis of RA. Patients with both IBD and RA were significantly older than those without RA (mean age 52.21 vs. 45.72 years, p < 0.001) and had a higher proportion of females (72.51% vs. 53.27%, p < 0.01). RA patients exhibited a greater risk of cardiovascular risk factors compared to non-RA patients, including diabetes [adjusted odd ratio (aOR ) 1.12 (1.09-1.16)], hypertension [aOR 1.19 (1.07-1.33)], hyperlipidemia [aOR 1.61 (1.60-1.63)], chronic kidney disease stage 1-4 [aOR 1.35 (1.29-1.41)], coronary artery disease [aOR 1.67 (1.65-1.69)], and heart failure [aOR 1.45 (1.43-1.48)]. However, there were no significant differences in the rates of IBD-related complications or in-hospital mortality between the two groups. The mean hospital LOS was 5.15 days for RA patients and 4.95 days for non-RA patients (p = 0.08), with similar total hospital charges ($48,442.7 vs. $48,720.3, p = 0.88). Conclusion This study shows hospitalized IBD patients with and without RA have similar hospitalization outcomes, however, patients with RA have a higher cardiovascular risk. The findings emphasize the importance of integrated, multidisciplinary management approaches for these patients, addressing not only their gastrointestinal and rheumatologic conditions but also their associated comorbidities.

RESUMEN

Background Enterocolitis due to Clostridium difficile infection (CDI) is one of the most common infectious causes of healthcare-associated diarrhea and a significant cause of morbidity and mortality among hospitalized patients. Gastroesophageal reflux disease (GERD) is notable for its high prevalence, variety of clinical presentations, and underrecognized morbidity. It is widely treated with acid suppression, both with over-the-counter and prescription medications. There are no studies evaluating the impact of GERD on CDI hospitalization. In this study, we aimed to analyze the influence of concomitant GERD on patients hospitalized for CDI enterocolitis. Methodology This was a retrospective, observational study where we extracted data from 2016 to 2020 from the National Inpatient Sample database. We included all patients hospitalized with a primary discharge diagnosis of CDI with or without a secondary diagnosis of GERD. We compared the demographics, comorbidities, and in-hospital outcomes between these two groups. Results This study identified 239,603 hospitalizations with a discharge diagnosis of CDI. Of these, 67,000 (28%) had a concurrent diagnosis of GERD. Patients with GERD had a higher prevalence of hypertension (41% vs. 35.5%, p < 0.01), hyperlipidemia (50% vs. 36.5%, p < 0.01), obesity (13.7% vs. 10.5%, p < 0.01), coronary artery disease (24.4% vs. 19.6%, p < 0.01), and chronic kidney disease (20.7% vs. 19.2%, p < 0.01). Notably, inpatient mortality was lower in CDI hospitalizations with GERD (0.66% vs. 1.46%, p < 0.01). The total hospital charge was reduced in the CDI with GERD group in comparison to the CDI without GERD group (39,599 vs. 43,589, p < 0.01). The length of hospital stay was similar between the two groups (5.3 vs. 5.4 days, p = 0.07). Regarding complications, CDI hospitalizations with GERD demonstrated lower rates of hypovolemic shock (0.5% vs. 0.73%, p = 0.06), septic shock (0.6% vs. 1.05%, p < 0.01), acute kidney injury (1.48% vs. 2.04%, p < 0.01), intestinal perforation (0.008% vs. 0.16%, p = 0.03), and lactic acidosis (0.008% vs. 0.16%, p = 0.03). Conversely, CDI patients with GERD had a higher rate of ileus (2.66% vs. 2.16%, p < 0.01). Conclusions Patients with CDI and concurrent GERD exhibited favorable in-hospital outcomes in terms of complication rates, mortality, and total hospital charges. Further research is required to comprehensively explore and validate these findings.

RESUMEN

Refeeding syndrome is the potentially fatal shift in fluids and electrolytes that may occur in malnourished patients after receiving artificial refeeding. Its hallmark feature is hypophosphatemia, although other electrolytes might also be affected. Fanconi syndrome is a generalized dysfunction of the proximal tubule characterized by proximal renal tubular acidosis (RTA), phosphaturia, glycosuria, aminoaciduria, and proteinuria. The etiology of Fanconi syndrome can be either acquired or inherited, and drugs, among them tenofovir, are a common acquired cause of this disease. We present the case of a patient with AIDS and polysubstance abuse who was admitted due to pneumonia, completed treatment, was then started on antiretroviral medication (ART) that included tenofovir alafenamide (TAF) and began presenting severe episodes of hypophosphatemia along with other electrolyte imbalances, leading the workup denoted in the case, severe complications and finally to the patient's demise. Most cases of tenofovir-related Fanconi syndrome are related to tenofovir disoproxil fumarate, but very few cases have been reported with TAF. Our case highlights this rare complication of therapy with TAF and how artificial feeding can contribute to severe electrolyte abnormalities and worsen outcomes.

RESUMEN

A 33-year-old female presented with a history of high-grade fever, cough, dyspnea, joint pain and myalgia. On examination, the patient was febrile with tachycardia, hypotension and decreased oxygen saturation. Chest auscultation revealed bilateral decreased air entry with crepitation supported by bilateral pulmonary infiltrates on chest X-ray. The laboratory investigations showed leukocytosis, thrombocytopenia, transaminitis and renal impairment. The patient was treated with intravenous fluids, ceftriaxone and levofloxacin; however, there was no clinical improvement till 48 h. She was then diagnosed with scrub typhus and dengue co-infection via serologies. Doxycycline was started following which the patient improved in 24 h. Scrub typhus can present with septic shock but does not respond to the usual antibiotics and the addition of doxycycline will result in rapid clinical improvement. Co-infection with other tropical diseases such as dengue is also common, hence it is important to test based on local endemicity.

RESUMEN

INTRODUCTION: The corona virus disease 2019 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 belonging to corona viruses which are enveloped positive stranded RNA viruses. Non-critical coronavirus disease 2019 patients often lack follow up visits which has led to incomplete understanding of disease process. The aim of this study was to find out the prevalence of persistent symptoms in such patients during two months follow-up to a district hospital. METHODS: This descriptive cross-sectional study was conducted in a district hospital from September 2020 to February 2021 among non-critical corona virus disease 2019 patients admitted to the isolation center of Nepal. Ethical approval was taken from the ethical review board of Nepal Health Research Council (reference number: 1707). Convenience sampling was done. Data was collected using a structured questionnaire. Data analysis was done using Statistical Package for the Social Sciences version 26. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 132 patients, 66 (50%) (41.5-58.5 at 95% Confidence Interval) patients had persistent symptoms at two-month follow-up. Forty-eight (36.4%) patients showed one symptom, 15 (11%) had two symptoms, and 3 (2%) had two or more symptoms. The most frequent symptom reported was fatigue in 17 (13%), cough in 15 (11%), myalgia in 9 (7%), and headache in 9 (7%). CONCLUSIONS: The prevalence of persistent symptoms at two months follow up in our study was lower than findings from other international studies.

RESUMEN

BACKGROUND: Resuscitation of a critically-ill child requires an accurate weight for fluids and medication dosing; however, weighing children on a scale while critically ill is not always practical. The objective of this study is to determine the accuracy of three different weight estimation methods (Broselow, PAWPER XL and Mercy tape) of children presenting to Patan Hospital, Nepal. METHODS: This was a prospective, cross-sectional study that included children presenting to the emergency department and under-fourteen outpatient clinic at Patan Hospital. Measured weight was compared to estimated weight of Broselow, PAWPER XL, and Mercy tapes. The mean percentage error and percentage of estimated weights that were within 10% (PW10) and 20% (PW20) of actual weight were calculated. Acceptable accuracy was determined as a PW10>70% and PW20>95%. A Bland-Altman analysis was done to determine agreement between each weight estimation method and actual weight. RESULTS: The study included 813 children. The mean age was 4.2 years (ranging from 4 days to 14 years) with 60% male. The mean percentage error (MPE) for Broselow, PAWPER XL and Mercy were -1.0% (SD 11.8), 0.7% (10.5) and 4.2% (11.9) respectively. The predicted weight within 10% was highest for the PAWPER XL (71.5%) followed by Broselow (63.2%) and Mercy (58.1%). The predicted weight within 20% of actual weight was 95.2%, 91.5% and 91.3% for PAWPER XL, Broselow and Mercy respectively. CONCLUSION: The PAWPER XL tape was the only method found to be accurate in estimating the weight of Nepalese children.

RESUMEN

BACKGROUND: Medical education can play important role in cultivating the willingness among the medical students to work in underprivileged areas after their graduation. Experiential learning through early exposure to primary health care centers could help students better understand the opportunities and challenges of such settings. However, the information on the real experiences and reflections of medical students on the rural primary health care settings from low-income countries like Nepal are still limited. The aim of this study is to demonstrate the learning process of the medical students through their reflective writings based on Kolb's theory of experiential learning. METHODS: The students wrote their experiences, observations and reflections on the experiential learning from the primary health care centers on individual logbook as part of their community posting assignments. We analyzed the data of 50 logbooks through content analysis using Kolb's experiential learning cycle as a theoretical framework. RESULTS: The students' reflections are structured around the four main learning stages of Kolb's experiential learning theory. Each learning stage consisted of different categories. The first stage consisted of concrete experiences on rural health and learning by doing. The second stage included their reflective observations on primary versus tertiary care, application of theoretical knowledge and role of supervisors. In the third stage, the students developed and refined their concepts on self-development, understanding reality, compassion and sense of responsibility. The final stage, active experimentation, included their immediate future plans, suggestions to improve curriculum, plans after becoming a doctor and suggestions to improve policies. CONCLUSION: This study provided important insights on different stages of experiential learning of medical students on primary health care in low resource rural settings. Reflective writing of experiential learning could be an important step to address the gaps in medical education for resource constraint settings like that of Nepal and other low-income countries.
