Safety and Efficacy of Metformin for Idiopathic Intracranial Hypertension. A U.S-Based Real-World Data Retrospective Multicenter Cohort Study.

Introduction: Idiopathic intracranial hypertension (IIH) remains a challenging condition to manage, with limited therapeutic options. This study investigated the potential of metformin as a novel treatment for IIH, exploring its effects on disease outcomes and safety profile. Methods: We conducted a retrospective cohort study using the TriNetX database, analyzing data from 2009 to August 2024. Patients diagnosed with IIH were included, with exclusions for other causes of elevated intracranial pressure and pre-existing diabetes. Propensity score matching was employed to balance cohorts according to age, sex, race, ethnicity, Hemoglobin A1C, and baseline body mass index (BMI) at the time of metformin initiation. Outcomes were assessed at various follow-up points up to 24 months. Results: Our study initially comprised 1,268 patients in the metformin group and 49,262 in the control group, with notable disparities in several parameters. Post-matching, both cohorts were refined to 1,267 patients each after matching with metformin group. Metformin-treated patients showed significantly lower risks of papilledema, headache, and refractory IIH status at all follow-up points (p<0.0001). The metformin group also had reduced rates of therapeutic spinal punctures and acetazolamide continuation. BMI reductions were more pronounced in the metformin group, with significant differences observed from 6 months onward (p<0.0001). Notably, metformin's beneficial effects persisted independently of BMI changes. The safety profile of metformin was favorable, with no significant differences in adverse events compared to the control group which did not receive metformin during the study timeframe. Conclusions: Our study provides evidence for metformin's potential as a disease-modifying therapeutic approach in IIH, demonstrating improvements across multiple outcomes. The benefits appear to extend beyond weight loss, suggesting complex mechanisms of action. These findings warrant further investigation through prospective clinical trials to establish metformin's role in IIH management and explore its underlying therapeutic mechanisms.

Decreased risk of recurrent acute pancreatitis with semaglutide and tirzepatide in people with type 2 diabetes or obesity with a history of acute pancreatitis: A propensity matched global federated TriNetX database-based retrospective cohort study.

BACKGROUND: Acute pancreatitis (AP) is a significant health concern with potential for recurrent episodes and serious complications. The risk of recurrence in type 2 diabetes (T2D) or obesity can be influenced by various factors and treatments, including GLP-1 receptor agonists (GLP-1RAs). This study evaluates the risk of recurrent AP among patients with a history of the condition, focusing on the effects of different GLP-1RA treatments. OBJECTIVES: Our objective is to compare the recurrence risks of AP between patients treated with different GLP-1RAs. METHODS: We conducted a retrospective cohort study using the TriNetX platform, encompassing 258,238 individuals with T2D or obesity who have a history of AP. We assessed the recurrence of AP over a five-year period, analyzing data on treatment regimens, with a focus on the use of Semaglutide, Tirzepatide, and other GLP-1RAs. RESULTS: GLP-1RA users experienced significantly lower recurrence rates of AP, with those without risk factors showing GLP-1RA users had a recurrence rate of 13.8 % compared to 40.9 % for non-users. Semaglutide and Tirzepatide showed the most favorable outcomes; Semaglutide users had lower recurrence rates than Exenatide (10.1 % vs. 27 %) and slightly lower than Dulaglutide (13.6 % vs. 15.4 %), though not statistically significant with Dulaglutide. Tirzepatide users displayed the lowest recurrence risk at 6.2 %, significantly lower than those on Semaglutide (11.7 %). CONCLUSIONS: GLP-1RAs, particularly Semaglutide and Tirzepatide, are associated with a reduced risk of recurrent AP in people with T2D or obesity. The differential risk profile between these drugs highlights the need for further studies and personalized treatment plans.

Small Intestine Ectopic Varices as a Cause of Obscure Gastrointestinal Bleeding in a Cirrhotic Patient.

Portal hypertension is a major complication of liver cirrhosis, leading to various life-threatening conditions. The most common of these is the formation and bleeding of varices at the portosystemic anastomosis. Varices are most commonly esophageal or gastric and less commonly ectopic. Although ectopic varices are rare, they should be considered as a cause of obscure gastrointestinal bleeding in cirrhotic patients. We present a case of ruptured ectopic varices in the small intestine of a known cirrhotic patient who presented with anemia and melena, alternated with hematochezia. The case was managed with Histoacryl® injection using push enteroscopy, resulting in adequate hemostasis.

Comparative outcomes of systemic diseases in people with type 2 diabetes, or obesity alone treated with and without GLP-1 receptor agonists: a retrospective cohort study from the Global Collaborative Network : Author list.

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are increasingly used to manage type 2 diabetes (T2D) and obesity. Despite their recognized benefits in glycemic control and weight management, their impact on broader systemic has been less explored. OBJECTIVE: This study aimed to evaluate the impact of GLP-1RAs on a variety of systemic diseases in people with T2D or obesity. METHODS: We conducted a retrospective cohort study using data from the Global Collaborative Network, accessed through the TriNetX analytics platform. The study comprised two primary groups: individuals with T2D and those with obesity. Each group was further divided into subgroups based on whether they received GLP-1RA treatment or not. Data were analyzed over more than a 5-year follow-up period, comparing incidences of systemic diseases; systemic lupus erythematosus (SLE), systemic sclerosis (SS), rheumatoid arthritis (RA), ulcerative colitis (UC), crohn's disease (CD), alzheimer's disease (AD), parkinson's disease (PD), dementia, bronchial asthma (BA), osteoporosis, and several cancers. RESULTS: In the T2D cohorts, GLP-1RA treatment was associated with significantly lower incidences of several systemic and metabolic conditions as compared to those without GLP-1RA, specifically, dementia (Risk Difference (RD): -0.010, p < 0.001), AD (RD: -0.003, p < 0.001), PD (RD: -0.002, p < 0.001), and pancreatic cancer (RD: -0.003, p < 0.001). SLE and SS also saw statistically significant reductions, though the differences were minor in magnitude (RD: -0.001 and - 0.000 respectively, p < 0.001 for both). Conversely, BA a showed a slight increase in risk (RD: 0.002, p < 0.001). CONCLUSIONS: GLP-1RAs demonstrate potential benefits in reducing the risk of several systemic conditions in people with T2D or obesity. Further prospective studies are needed to confirm these effects fully and understand the mechanisms.

Small Bowel Ischemia and Ischemic Colitis Secondary to Thrombotic Thrombocytopenic Purpura in a Patient With Systemic Lupus Erythematous: A Rare Clinical Entity.

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening hematologic disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ dysfunction. This report highlights a rare case of small bowel ischemia and ischemic colitis caused by TTP in a 35-year-old woman with systemic lupus erythematosus (SLE), hypertension, and end-stage renal disease on hemodialysis. She presented with severe abdominal pain, diarrhea, vomiting, and bloody bowel movements. Diagnosed through CT, EGD, and colonoscopy and confirmed by ADAMTS13 levels, she was treated with plasma exchange, steroids, and rituximab. After standard therapies failed, resection anastomosis surgery led to clinical improvement. This case underscores the importance of early recognition and treatment of TTP in SLE patients to improve prognosis and reduce morbidity and mortality.

The Egyptian journey from having the highest prevalence of hepatitis C virus to being the first to achieve "gold tier" in conquering the disease.

Hepatitis C virus (HCV) is a major global health concern, particularly in Egypt, due to historic schistosomiasis control efforts that inadvertently led to widespread HCV transmission. This study aimed to evaluate the efficacy of Egypt's national strategies in controlling and reducing the prevalence of HCV, including introducing sofosbuvir and implementing the "100 Million Healthy Lives" campaign. The approach includes a review of epidemiological data, an analysis of the national HCV control strategies implemented, and an assessment of their outcomes, focusing on the period from 2006 to 2022. Significant milestones were achieved, including a drastic reduction in new HCV infections from 300 per 100,000 in 2014 to 9 per 100,000 in 2022 and successful treatment of over 4 million people. Egypt has become the first country in the world to achieve the "gold tier" status based on World Health Organization criteria on the path to eradication of HCV. Egypt's comprehensive approach can serve as a model for similar endemic regions. Other nations with high HCV prevalence might benefit from adopting similar multidimensional strategies, emphasizing prevention and treatment.

Evaluating the effectiveness of combined T4 and T3 therapy or desiccated thyroid versus T4 monotherapy in hypothyroidism: a systematic review and meta-analysis.

BACKGROUND: Persistent symptoms in hypothyroid patients despite normalized TSH levels suggest the need for alternative treatments. This study aims to evaluate the effectiveness of combined T4 and T3 therapy or desiccated thyroid (DTE) compared to T4 monotherapy, with a focus on thyroid profile, lipid profile, and quality of life metrics. METHODS: We conducted a systematic review in Embase, Medline/PubMed, and Web of Science up to 11/23/2023. We used the following keywords: "Armour Thyroid," OR "Thyroid extract," OR "Natural desiccated thyroid," OR "Nature-Throid," "desiccated thyroid," OR "np thyroid," OR "Synthroid," OR "levothyroxine," OR "Liothyronine," "Cytomel," OR "Thyroid USP," OR "Unithroid." AND "hypothyroidism. " We only included RCTs and excluded non-RCT, case-control studies, and non-English articles. RESULTS: From 6,394 identified records, 16 studies qualified after screening and eligibility checks. We included two studies on desiccated thyroid and 15 studies on combined therapy. In this meta-analysis, combination therapy with T4 + T3 revealed significantly lower Free T4 levels (mean difference (MD): -0.34; 95% CI: -0.47, -0.20), Total T4 levels (mean difference: -2.20; 95% CI: -3.03, -1.37), and GHQ-28 scores (MD: -2.89; 95% CI: -3.16, -2.63), compared to T4 monotherapy. Total T3 levels were significantly higher in combined therapy (MD: 29.82; 95% CI: 22.40, 37.25). The analyses demonstrated moderate to high heterogeneity. There was no significant difference in Heart Rate, SHBG, TSH, Lipid profile, TSQ-36, and BDI Score. Subjects on DTE had significantly higher serum Total T3 levels (MD: 50.90; 95% CI: 42.39, 59.42) and significantly lower serum Total T4 (MD: -3.11; 95% CI: -3.64, -2.58) and Free T4 levels (MD: -0.50; 95% CI: -0.57, -0.43) compared to T4 monotherapy. Moreover, DTE treatment showed modestly higher TSH levels (MD: 0.49; 95% CI: 0.17, 0.80). The analyses indicated low heterogeneity. There was no significant difference in Heart Rate, SHBG, Lipid profile, TSQ-36, GHQ-28, and BDI Score. CONCLUSIONS: Our study revealed that combined therapy and DTE lead to higher T3 and lower T4 levels, compared to T4 monotherapy in hypothyroidism. However, no significant effects on heart rate, lipid profile, or quality of life were noted. Given the heterogeneity of results, personalized treatment approaches are recommended.

Electrolyte disturbances in patients hospitalized for COVID-19 infection: An observational study.

There are multiple mechanisms by which The Coronavirus-19 (COVID-19) infection can cause electrolyte abnormalities, which may not be the case for bacterial causes of pneumonia. This study aimed to assess the differences in electrolyte levels between patients suffering from COVID-19 and bacterial pneumonia. This is an original, retrospective study. Two cohorts of hospitalized patients were included, 1 suffering from COVID-19 and the other from bacterial pneumonia. Their day 1 and day 3 levels of sodium, potassium, magnesium, and phosphorus, as well as their outcomes, were extracted from the charts. Statistical analysis was subsequently performed. Mean admission levels of sodium, potassium, phosphorus, and magnesium were 135.64 ±â€…6.13, 4.38 ±â€…0.69, 3.53 ±â€…0.69, and 2.03 ±â€…0.51, respectively. The mean day 3 levels of these electrolytes were 138.3 ±â€…5.06, 4.18 ±â€…0.59, 3.578 ±â€…0.59, and 2.11 ±â€…0.64, respectively. Patients suffering from bacterial pneumonia were significantly older (N = 219, mean = 64.88 ±â€…15.99) than patients with COVID-19 pneumonia (N = 240, mean = 57.63 ±â€…17.87). Bacterial pneumonia group had significantly higher serum potassium (N = 211, mean = 4.51 ±â€…0.76), and magnesium (N = 115, mean = 2.12 ±â€…0.60) levels compared to COVID-19 group (N = 227, mean = 4.254 ±â€…0.60 for potassium and N = 118, mean = 1.933 ±â€…0.38 for magnesium). Only magnesium was significantly higher among day 3 electrolytes in the bacterial pneumonia group. No significant association between electrolyte levels and outcomes was seen. We found that COVID-19 patients had lower potassium and magnesium levels on admission, possibly due to the effect of COVID-19 on the renin-angiotensin-aldosterone system as well as patient characteristics and management. We did not find enough evidence to recommend using electrolyte levels as a determinator of prognosis, but more research is needed.

The Royal College of Paediatrics and Child Health Retinopathy of Prematurity Screening Guidelines (2022): a series of treated infants falling outside the updated criteria.

BACKGROUND/OBJECTIVES: Screening for retinopathy of prematurity (ROP) is a core healthcare intervention in premature babies to avoid preventable sight loss. A variety of screening criteria are in place globally for this purpose. The Royal College of Paediatrics and Child Health recently updated the United Kingdom ROP screening guidelines (March 2022). A key change was the reduction in the gestational age (GA) to warrant retinal screening (from 32 to 31 weeks). SUBJECTS/METHODS: In the course of informal national surveillance during guideline development (2017-2022) and soon after, babies under our care falling outside the updated screening criteria who underwent treatment for ROP were identified. A retrospective case review was carried out. RESULTS: Six babies were identified as having undergone screening and treatment, prior to implementation of the new guidance. Screening and treatment would have been forfeited as per the March 2022 guidelines. All six had numerous systemic risk factors for developing ROP. Specifically, all had documented poor postnatal weight gain. CONCLUSIONS: We present this case series to bring forth an urgent discussion amongst key stakeholders as to whether the new guidance, as it stands, is safe and fit for purpose.

Relation between non-alcoholic fatty liver disease and carotid artery intimal media thickness as a surrogate for atherosclerosis: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD), characterized by hepatic steatosis without heavy alcohol consumption or other chronic conditions, encompasses a spectrum from non-alcoholic fatty liver to non-alcoholic steatohepatitis leading to cirrhosis. This analysis aimed to investigate the correlation between NAFLD and carotid intimal media thickness (C-IMT), a non-invasive surrogate for atherosclerosis. METHODOLOGY: Database searches, including PubMed, EMBASE and Cochrane Library, yielded studies up to April 2023. Included were studies exploring the NAFLD-C-IMT relationship in populations aged >18 years. Exclusions comprised non-English papers, those involving animals or pediatric populations and studies lacking control groups. RESULTS: No statistical significance was noted between mild and moderate NAFLD compared to the control group regarding C-IMT [95% confidence intervals (CI): -0.03, 0.12] and (95% CI: -0.03, 0.21), respectively. There was a statistically significant difference only in the Severe NAFLD group ( P value 0.03). NAFLD with and without metabolic syndrome showed statistically significant differences compared to control regarding C-IMT (95% CI: 0.04, 0.12) and (95% CI: 0.01, 0.07), respectively. Fifty-nine studies were mentioned without classification of NAFLD severity and revealed a high statistically significant difference between NAFLD and controls regarding C-IMT with (95% CI: 0.09, 0.12, P < 0.00001). Stratified analysis according to sex was done in two studies and revealed statistical differences between NAFLD and control regarding C-IMT in both groups. CONCLUSION: This meta-analysis underscores a significant association between NAFLD and increased C-IMT, emphasizing the importance of assessing C-IMT in NAFLD patients to identify cardiovascular risk and tailor therapeutic interventions for improved patient outcomes.

Glucagon-like peptide-1 receptor agonists as a possible intervention to delay the onset of type 1 diabetes: A new horizon.

Type 1 diabetes (T1D) is a chronic autoimmune condition that destroys insulin-producing beta cells in the pancreas, leading to insulin deficiency and hyper-glycemia. The management of T1D primarily focuses on exogenous insulin replacement to control blood glucose levels. However, this approach does not address the underlying autoimmune process or prevent the progressive loss of beta cells. Recent research has explored the potential of glucagon-like peptide-1 receptor agonists (GLP-1RAs) as a novel intervention to modify the disease course and delay the onset of T1D. GLP-1RAs are medications initially developed for treating type 2 diabetes. They exert their effects by enhancing glucose-dependent insulin secretion, suppressing glucagon secretion, and slowing gastric emptying. Emerging evidence suggests that GLP-1RAs may also benefit the treatment of newly diagnosed patients with T1D. This article aims to highlight the potential of GLP-1RAs as an intervention to delay the onset of T1D, possibly through their potential immunomodulatory and anti-inflammatory effects and preservation of beta-cells. This article aims to explore the potential of shifting the paradigm of T1D management from reactive insulin replacement to proactive disease modification, which should open new avenues for preventing and treating T1D, improving the quality of life and long-term outcomes for individuals at risk of T1D.

Impact of treatment with GLP-1RAs on suicide attempts in adults persons with type 2 diabetes: A retrospective comparative effectiveness study based on a global TriNetX health research database.

OBJECTIVE: To assess the association between glucagon-like peptide-1 receptor agonists (GLP-1RA) treatment and the risk of suicide attempts in people with type 2 diabetes (T2D), with a focus on subgroups with and without a history of depression or suicide attempts. METHODS: This retrospective cohort study utilized TriNetX, a federated network of real-world data. Using the Global Collaborative Network data, we collected electronic medical records from 113 health care organizations with 135 million patient records with 8 million with T2D, 83% from the United States. The four cohorts were identified based on age, medication, diagnosis, and presence of depression or suicide attempts. Analytic methods included measures of association and number of Instances, with propensity score matching employed to mitigate potential confounders. The primary outcome was the incidence of suicide attempts among people with T2D with GLP-1RA treatment in comparison with dipeptidyl peptidase-4 inhibitor (DPP-4i) treatment. RESULTS: People with T2D treated with GLP-1RA consistently exhibited a lower risk of suicide attempts compared to those treated with DPP-4i. This was particularly significant in people with a history of depression or suicide attempts. The risk and odds ratios were significantly lower in the GLP-1RA-treated cohorts than in DPP-4i across all analyses. CONCLUSION: As compared with DPP-4i, our analysis shows a protective effect associated with GLP-1RA treatment on the risk of suicide attempts among people with T2D. However, further research, particularly prospective and randomized studies, is necessary to confirm these observations and understand the underlying mechanisms.

Assessing and improving radiation safety in cardiac catheterization: a study from Cairo University Hospital.

BACKGROUND: Catheter laboratories are high-radiation exposure environments, especially during X-ray procedures like percutaneous transluminal coronary angioplasty and electrophysiological studies. Radiation exposure poses risks of stochastic (e.g., cancer) and deterministic (e.g., skin changes) effects. This study assessed radiation safety and health practices in a cardiac catheterization unit to optimize radiation safety. A cross-sectional study in Cairo University Hospital (March-September 2019) evaluated 700 patients and healthcare workers. Real-time radiation measurements, educational lectures, and radiation protection measures were implemented in three phases. Data on radiation exposure, procedures, and compliance were collected and analyzed. RESULTS: The total procedure time and fluoroscopy time per cardiologist did not significantly differ between phases, but there was a statistically significant reduction in the mean total cumulative radiation doses between Phase I and Phase III for cardiologists (P = 0.013). Among nurses and technicians, there was no significant difference in radiation doses between the two phases. Significant correlations were found between operators' radiation doses, procedure time, and fluoroscopy time. Patients' radiation doses decreased significantly from Phase I to Phase III, with correlations between dose, procedure time, and gender. Compliance with radiation protection measures was suboptimal. CONCLUSIONS: Compliance with radiation safety standards in the cardiac catheterization unit at the Cairo University Hospital needs improvement. The study highlights the importance of adhering to radiation safety principles and optimizing protective measures to reduce radiation exposure for both patients and healthcare personnel. Despite low compliance, significant reductions in radiation doses were achieved with increased awareness and adherence to specific protection measures. Future efforts should focus on enhancing radiation safety protocols and organ-specific radiation impact assessments.

Neuroprotective potential of Erigeron bonariensis ethanolic extract against ovariectomized/D-galactose-induced memory impairments in female rats in relation to its metabolite fingerprint as revealed using UPLC/MS.

Erigeron bonariensis is widely distributed throughout the world's tropics and subtropics. In folk medicine, E. bonariensis has historically been used to treat head and brain diseases. Alzheimer's disease (AD) is the most widespread form of dementia initiated via disturbances in brain function. Herein, the neuroprotective effect of the chemically characterized E. bonariensis ethanolic extract is reported for the first time in an AD animal model. Chemical profiling was conducted using UPLC-ESI-MS analysis. Female rats underwent ovariectomy (OVX) followed by 42 days of D-galactose (D-Gal) administration (150 mg/kg/day, i.p) to induce AD. The OVX/D-Gal-subjected rats received either donepezil (5 mg/kg/day) or E. bonariensis at 50, 100, and 200 mg/kg/day, given 1 h prior to D-Gal. UPLC-ESI-MS analysis identified 42 chemicals, including flavonoids, phenolic acids, terpenes, and nitrogenous constituents. Several metabolites, such as isoschaftoside, casticin, velutin, pantothenic acid, xanthurenic acid, C18-sphingosine, linoleamide, and erucamide, were reported herein for the first time in Erigeron genus. Treatment with E. bonariensis extract mitigated the cognitive decline in the Morris Water Maze test and the histopathological alterations in cortical and hippocampal tissues of OVX/D-Gal-subjected rats. Moreover, E. bonariensis extract mitigated OVX/D-Gal-induced Aß aggregation, Tau hyperphosphorylation, AChE activity, neuroinflammation (NF-κBp65, TNF-α, IL-1ß), and apoptosis (Cytc, BAX). Additionally, E. bonariensis extract ameliorated AD by increasing α7-nAChRs expression, down-regulating GSK-3ß and FOXO3a expression, and modulating Jak2/STAT3/NF-ĸB p65 and PI3K/AKT signaling cascades. These findings demonstrate the neuroprotective and memory-enhancing effects of E. bonariensis extract in the OVX/D-Gal rat model, highlighting its potential as a promising candidate for AD management.

Association between non-alcoholic fatty liver disease and coronary artery disease outcomes: A systematic review and meta-analysis.

OBJECTIVES: To evaluate the association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular outcomes, including angina, coronary artery disease (CAD), coronary artery calcification (CAC), myocardial infarction (MI), and calcified coronary plaques. METHODS: A comprehensive search of databases, including PubMed, EMBASE, and Cochrane Library, was conducted up to January 2023. Studies were included investigating the relationship between NAFLD and cardiovascular outcomes in adult populations. Exclusion criteria were studies on animals, pediatric populations, and those not published in English. Two reviewers assessed the risk of bias in the included studies using the Newcastle-Ottawa Scale. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS: The meta-analysis included 32 studies with a total of 5,610,990 participants. NAFLD demonstrated significant associations with increased risks of angina (Relative Risk (RR): 1.45, 95% CI: 1.17, 1.79), CAD (RR: 1.21, 95% CI: 1.07, 1.38), CAC >0 (RR: 1.39, 95% CI: 1.15, 1.69), and calcified coronary plaques (RR: 1.55, 95% CI: 1.05, 2.27). However, no significant association was found between NAFLD and CAC >100 (RR: 1.16, 95% CI: 0.97, 1.38) or MI (RR: 1.70, 95% CI: 0.16, 18.32). CONCLUSION: The meta-analysis demonstrated a significant association between NAFLD and cardiovascular outcomes independent of conventional cardiovascular disease (CVD) risk factors. These findings emphasize the importance of prevention, early detection, and proper management of NAFLD.

From Emergence to Endemicity: A Comprehensive Review of COVID-19.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), later renamed coronavirus disease 2019 (COVID-19), was first identified in Wuhan, China, in early December 2019. Initially, the China office of the World Health Organization was informed of numerous cases of pneumonia of unidentified etiology in Wuhan, Hubei Province at the end of 2019. This would subsequently result in a global pandemic with millions of confirmed cases of COVID-19 and millions of deaths reported to the WHO. We have analyzed most of the data published since the beginning of the pandemic to compile this comprehensive review of SARS-CoV-2. We looked at the core ideas, such as the etiology, epidemiology, pathogenesis, clinical symptoms, diagnostics, histopathologic findings, consequences, therapies, and vaccines. We have also included the long-term effects and myths associated with some therapeutics of COVID-19. This study presents a comprehensive assessment of the SARS-CoV-2 virology, vaccines, medicines, and significant variants identified during the course of the pandemic. Our review article is intended to provide medical practitioners with a better understanding of the fundamental sciences, clinical treatment, and prevention of COVID-19. As of May 2023, this paper contains the most recent data made accessible.

Emerging therapeutic options for non-alcoholic fatty liver disease: A systematic review.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a prevalent cause of chronic liver disease and ranks third among the causes of transplantation. In the United States alone, annual medical costs are approximately 100 billion dollars. Unfortunately, there is no Federal Drug Administration (FDA)-approved medication for its treatment. However, various clinical trials are investigating several therapeutic classes that could potentially treat NAFLD. It is valuable to have a compilation of the data available on their efficacy. AIM: To assess the efficacy of cyclophilin inhibitors, fibroblast growth factor 21 analogs (FGF21), and dual and pan peroxisome proliferator-activated receptor (PPAR) agonists for treating NAFLD. METHODS: A comprehensive literature search using keywords including cyclophilin inhibitor, FGF agonist, pan-PPAR agonists, dual-PPAR agonist, NAFLD, non-alcoholic steatohepatitis, and fatty liver was conducted on October 29, 2022, in PubMed, EMBASE, Cochrane Library, Scopus and Web of Science. Animal and human research, case reports, and published articles in English from all countries with patients aged 18 and above were included. Only articles with a National Institutes of Health (NIH) Quality Assessment score of five or higher out of eight points were included. Articles that were narrative or systematic reviews, abstracts, not in English, focused on patients under 18 years old, did not measure outcomes of interest, were inaccessible, or had a low NIH Quality Assessment score were excluded. Each article was screened by two independent researchers evaluating relevance and quality. Resources were scored based on the NIH Quality Assessment Score; then, pertinent data was extracted in a spreadsheet and descriptively analyzed. RESULTS: Of the 681 records screened, 29 met the necessary criteria and were included in this review. These records included 12 human studies and 17 animal studies. Specifically, there were four studies on cyclophilin inhibitors, four on FGF agonists/analogs, eleven on pan-PPAR agonists, and ten on dual-PPAR agonists. Different investigational products were assessed: The most common cyclophilin inhibitor was NV556; FGF agonists and analogs was Efruxifermin; pan-PPAR agonists was Lanifibranor; and dual-PPAR agonists was Saroglitazar. All classes were found to be statistically efficacious for the treatment of NAFLD, with animal studies demonstrating improvement in steatosis and/or fibrosis on biopsy and human studies evidencing improvement in different metabolic parameters and/or steatosis and fibrosis on FibroScan (P < 0.05). CONCLUSION: The data analyzed in this review showed clinically significant improvement in individual histological features of NAFLD in both animal and human trials for all four classes, as well as good safety profiles (P < 0.05). We believe this compilation of information will have positive clinical implications in obtaining an FDA-approved therapy for NAFLD.

Hypophosphatemia in Patients With Multiple Myeloma.

Hypophosphatemia is among the most common electrolyte abnormalities, especially among patients with underlying malignancies, and is frequently associated with adverse prognoses. Phosphorus levels are regulated through a number of mechanisms, including parathyroid hormone (PTH), fibroblast growth factor-23 (FGF-23), vitamin D, and other electrolyte levels themselves. Clinically, the findings are nonspecific, and the diagnosis is frequently delayed. This article is a narrative literature review. The PubMed database was searched for relevant articles pertaining to hypophosphatemia causes and consequences in patients suffering from multiple myeloma. We found a variety of causes of hypophosphatemia in patients with multiple myeloma. Tumor-induced osteopenia, although more common among patients with small squamous cell carcinomas, can occur with multiple myeloma as well. Additionally, both light chains themselves and medications can trigger Fanconi syndrome, which leads to phosphorus wasting by the kidney. Bisphosphonates, in addition to being a possible cause of Fanconi syndrome, lead to a decrease in calcium levels, which then stimulates parathyroid hormone (PTH) release, predisposing the patient to significant hypophosphatemia. Additionally, many of the more modern medications used to manage multiple myeloma have been associated with hypophosphatemia. A better understanding of those mechanisms may give clinicians a clearer idea of which patients may need more frequent screening as well as what the potential triggers in the individual patient may be.

Impact of erythropoietin therapy on cardiorenal syndrome: A systematic review with meta-analysis.

BACKGROUND: Heart and kidney dysfunction frequently coexist in patients with acute heart failure due to the overlap between these two organ systems. Cardiorenal syndrome (CRS) results from pathology occurring in the heart and kidneys along with the consequences of dysfunction in one organ contributing to dysfunction in the other and vice versa. AIM: To evaluate the use of erythropoietin (EPO) in patients with CRS and its effects on hemoglobin (Hb), major cardiovascular (CV) events, and hospitalization rates. METHODS: On February 24, 2022, searches were conducted using PubMed, MEDLINE, and EMBASE, and 148 articles were identified. A total of nine studies were considered in this systematic review. We assessed the included articles based on the National Heart, Lung, and Blood Institute quality assessment tools for controlled intervention and observational cohort or cross-sectional studies. An assessment of bias risk was conducted on the chosen studies, and data relevant to our review was extracted. RESULTS: The systematic review of these studies concluded that most existing literature indicates that EPO improves baseline Hb levels and decreases myocardial remodeling and left ventricular dysfunction without reducing CV mortality. In addition, the effect of EPO on the hospitalization rate of patients with CRS needs to be further studied since this relationship is unknown. Future studies, such as randomized controlled clinical trials and prospective cohort studies, should be conducted to enhance the literature on the potential of EPO therapy in patients with CRS. CONCLUSION: Our systematic review suggests that EPO therapy may have a significant role in managing CRS. The review highlights the potential benefits of EPO in improving baseline Hb levels, reducing the risk of major CV events, improving cardiac remodeling, myocardial function, New York Heart Association class, and B-type natriuretic peptide levels. However, the effect of EPO treatment on hospitalization remains unclear and needs further exploration.

A Case of Diabetic Ketoacidosis Presented With Severe Rhabdomyolysis-Induced Acute Kidney Injury.

We present a patient who presented with diabetic ketoacidosis and severe rhabdomyolysis-induced acute kidney injury. The patient developed generalized edema, nausea, and vomiting, and his kidney function deteriorated, necessitating renal replacement therapy, despite the successful treatment of his initial conditions. A comprehensive evaluation was conducted to determine the underlying cause of the severe rhabdomyolysis, including autoimmune myopathies, viral infections, and metabolic disorders. A muscle biopsy revealed necrosis and myophagocytosis but no significant inflammation or myositis. The patient's clinical and laboratory results improved with appropriate treatment, including temporary dialysis and erythropoietin therapy, and he was discharged to continue his rehabilitation with home health care.
