After applying exclusion criteria, 175 COVID-19 hospitalized patients admitted to the Tishreen Hospital from January 1 to July 31, 2021 were retrospectively enrolled in this study. Baseline characteristics and in-hospital mortality rate were assessed between hypertensive (N = 91, 52%) and non-hypertensive (N = 84, 48%) patients, as well as between patients taking ACEis/ARBs and non-ACEis/ARBs within the hypertensive group. A lower mortality rate (51.2 versus 31.9%, p = 0.009) was observed in the hypertensive group (mean age 64.6 years, 64.8% males) compared to the non-hypertensive (mean age 62.6 years, 66.7% males). Patients' mortality in the non-hypertensive group was associated with lower blood oxygen saturation (SPO2 = 75 versus 86%, p = 0.002), increased levels of inflammatory (CRP, white blood cell and neutrophils count), and tissue/renal injury markers (LDH, urea, and creatinine). In the hypertensive group, a lower mortality rate was noted in the ACEis/ARBs group compared to the non-ACEis/ARBs (24.1 versus 45.5%, p = 0.036), and this was associated with a decrease in D-DIMER levels, although not significant (1723 versus 2683 ng/mL, p > 0.05). Death in the non-ACEis/ARBs group was associated with decreased SPO2 and tissue/renal injury markers (LDH, CK, AST, urea, and creatinine). We concluded that hypertension is not a direct cause of poor prognosis in COVID-19 patients and that multi-organ damage is a significant indicator of death from COVID-19. RAS inhibitors could improve the survival of hypertensive COVID-19 patients.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"863-875"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141792671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied the association between GLP-1a therapy and changes in weight and HbA1c in a real-world patient population. In this retrospective cohort study of patients seen in a primary care clinic between 2012 and 2021, we examined the change in weight and HbA1c over 12 months in a cohort of patients with at least one prescription for a GLP-1a. Within this cohort, treatment was defined as having ≥2 GLP-1a prescriptions at a therapeutic dosage separated by ≥10 months. The cohort included 693 patients of whom 393 (57%) were treated with GLP-1a therapy.

One hundred five participants completed the survey, of whom 61% were infectious disease physicians, with 68.6% having more than 10 years of experience. That the TPE procedure could significantly affect plasma concentrations of antimicrobial agents was reported by 74.3% of the respondents. Among the physicians, 42.9% suggest antimicrobial dose adjustment, and 38.1% recommend temporarily discontinuing antimicrobial drug administration during TPE. Therapeutic drug monitoring was recommended by 33.3% of the respondents for certain antimicrobials, mainly glycopeptides and aminoglycosides, in patients undergoing concurrent TPE. Furthermore, 59.3% of physicians sometimes consult with another healthcare professional for treatment management, most commonly a pharmacist or a clinical pharmacist and an infectious diseases specialist. The core questions regarding potential drug-, procedure-, and patient-related antimicrobial elimination factors via TPE were responded to accurately by less than half of the physicians. It was clear that they had a lack of clinical practices and knowledge regarding antimicrobial management during TPE. To ensure the therapeutic efficacy of antimicrobials and avoid treatment failure, physicians should improve their practice strategies and consider antimicrobial elimination factors with TPE in this data-poor setting.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"920-929"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141792666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the effect of VDR Bsml (rs1544410) and TLR2 23bp indel variants on the clinical status of Turkish patients with COVID-19 disease. A total of 312 people, including 106 intensive care unit (ICU) patients, 103 symptomatic hospitalized patients, and 103 healthy controls, were included in the study. The VDR BsmI and TLR2 23bp indel were genotyped using polymerase chain reaction and/or restriction fragment length fraction methods. The VDR BsmI b/b genotype and b allele were higher in symptomatic patients compared to the healthy control group (p = 0.035). The VDR BsmI B/B and B/b genotype distribution did not differ between ICU patients and both symptomatic patients and controls (p > 0.05). We found that B/B:B/b+b/b and B/B+B/b:b/b were significantly different in symptomatic patients compared to controls (p = 0.033 and p = 0.041, respectively). The VDR BsmI b/b genotype distribution was found to be lower in deceased patients than in living patients (p = 0.023). There was no significant difference between the groups in terms of TLR2 23bp indel genotype and allele distribution (p > 0.05).

It plays a significant role in various cardiovascular functions, including bioenergetics, electrical activity, and programmed cell death. Minor deficiencies of iron have been found to have negative impact on cardiovascular function in patients with heart failure (HF). The contractility of human cardiomyocytes is impaired by iron deficiency (ID), which results in reduced mitochondrial function and lower energy production, ultimately leading to cardiac function impairment, contributing to significant morbidity and mortality in patients with HF. This review discusses iron homeostasis within the human body, as well as ID pathophysiology and its role in HF. Focusing on therapeutic approaches including iron supplementation and/or repletion in patients with ID and HF, comparing results from recent clinical trials. Intravenous (IV) iron therapy has shown promising results in treating ID in HF patients. Large, randomized trials and meta-analysis, like Ferinject Assessment in patients with ID and chronic HF, AFFIRM-AHF, IRONMAN, and HEART-FID have demonstrated the efficacy of IV iron supplementation with IV ferric carboxymaltose or IV ferric derisomaltose in reducing hospitalizations and improving quality of life in patients with Heart Failure with reduced ejection fraction (HFrEF), New York Heart Association (NYHA) II-III. However, survival and mortality have demonstrated no improvement during acute exacerbations of HF or in outpatient management. The potential benefits of IV iron across the entire HF spectrum and its interaction with other HF therapies remain areas of interest for further research.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"787-797"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141792669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kidney diseases cause morbidity and mortality in patients living with HIV (PLWH), though cART has permitted kidney transplants with acceptable post-transplant graft and patient survival. Risk of allograft rejection remains high, which may be related to interactions between cART, specifically protease inhibitors (PI), and immunosuppressants prescribed post-transplant. This systematic review evaluates renal transplant outcomes in PLWH treated with PI- vs non-PI-based cART. A search strategy was generated with terms related to renal transplant, HIV, and cART and run on PubMed, Embase, Scopus, and Cochrane. Studies were evaluated using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on Covidence by two reviewers and then evaluated for bias. Of 803 studies, 9 were included. Included papers were prospective or retrospective cohort studies or chart reviews of adult patients. Outcome measures included acute graft rejection, graft survival, and patient survival. One study had significant results demonstrating that PI-based therapy was correlated with increased graft rejection rates. Two studies demonstrated significant graft survival benefit to non-PI-based therapy, while one demonstrated significant benefit to PI-based therapy. Two studies found significant patient survival benefit to non-PI-based therapy. For each outcome measure, remaining data suggested improved outcomes with non-PI-based therapies without achieving statistical significance. The results demonstrate superior outcomes in PLWH taking non-PI-based cART, though the paucity of significant results suggests that PLWH who require PI-based cART for virological control may continue their regimen safely post-kidney transplant.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"776-783"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140859375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these tools have not been investigated extensively in the Latina population. Given that the highest rate of NAFLD in Latinos and the most severe presentation of non-alcoholic fatty liver disease (NAFLD) is more common in women, we hypothesize that ethnicity may play a role in predicting liver fibrosis, particularly in women. We determined whether ethnicity alone or in association with other parameters can predict the severity of fibrosis in women with NAFLD when included in four tools. We retrospectively included 562 Latina and 133 White Caucasian women with a history of NAFLD. Associations between ethnicity and liver fibrosis severity using the four fibrosis predictor models were studied using backward selection multinomial logistic regression. Latina women compared to White showed lower body mass index (p < 0.001), higher HbA1c (p < 0.001), lower prevalence of bariatric surgery (p < 0.001), lower likelihood to smoke (p = 0.003), and higher prevalence of chronic kidney disease stages 3-5 (p = 0.01). Some clinical variables were associated with fibrosis but not univocally in each tool. We did not find differences in the outcome of the four models when holding all other factors and examining ethnicity alone between Latina and White women. Although we did not include data on liver histology, this is the first study examining the role of ethnicity in predicting the severity of fibrosis using established noninvasive scores and documenting no association between Latina ethnicity and the severity of fibrosis in women with NAFLD.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"697-704"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141310889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
