Twelve-month effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide in people with HIV: Real-world insights from BICSTaR cohorts.

BACKGROUND: Real-world evidence is an essential component of evidence-based medicine. The aim of the BICSTaR (BICtegravir Single Tablet Regimen) study is to assess effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in antiretroviral treatment-naïve (TN) and treatment-experienced (TE) people with HIV. METHODS: BICSTaR is a prospective, observational cohort study. Participants (≥18 years) are being followed for 24 months. A pooled analysis is presented at 12 months, with the primary endpoint of effectiveness (HIV-1 RNA <50 copies/mL) and secondary endpoints of safety and tolerability (as per protocol). An exploration of patient-reported outcome measures using standardized questionnaires is included. RESULTS: Between June 2018 and May 2021, 1552 people with HIV were enrolled across 12 countries. The analysed population comprised 1509 individuals (279 TN, 1230 TE); most were white (76%), male (84%) and had one or more comorbid conditions (68%). Median age was 47 years. After 12 months of B/F/TAF treatment, HIV-1 RNA was <50 copies/mL in 94% (221/236) of TN participants and 97% (977/1008) of TE participants. Median CD4 cell count increased by 214 cells/µL (p < 0.001) in TN participants and 13 cells/µL (p = 0.014) in TE participants; median CD4/CD8 ratios increased by 0.30 and 0.03, respectively (both p < 0.001). Persistence was high at 12 months (TN, 97%; TE, 95%). No resistance to B/F/TAF emerged. Study drug-related adverse events occurred in 13% of participants through 12 months, leading to B/F/TAF discontinuation in 6%. CONCLUSIONS: The findings of this study provide robust real-world evidence to support the broad use of B/F/TAF in both TN and TE people with HIV.

Clinicopathological profile of peritoneal tuberculosis and a new scoring model for predicting mortality: an international ID-IRI study.

Existing literature about peritoneal tuberculosis (TBP) is relatively insufficient. The majority of reports are from a single center and do not assess predictive factors for mortality. In this international study, we investigated the clinicopathological characteristics of a large series of patients with TBP and determined the key features associated with mortality. TBP patients detected between 2010 and 2022 in 38 medical centers in 13 countries were included in this retrospective cohort. Participating physicians filled out an online questionnaire to report study data. In this study, 208 patients with TBP were included. Mean age of TBP cases was 41.4 ± 17.5 years. One hundred six patients (50.9%) were females. Nineteen patients (9.1%) had HIV infection, 45 (21.6%) had diabetes mellitus, 30 (14.4%) had chronic renal failure, 12 (5.7%) had cirrhosis, 7 (3.3%) had malignancy, and 21 (10.1%) had a history of immunosuppressive medication use. A total of 34 (16.3%) patients died and death was attributable to TBP in all cases. A pioneer mortality predicting model was established and HIV positivity, cirrhosis, abdominal pain, weakness, nausea and vomiting, ascites, isolation of Mycobacterium tuberculosis in peritoneal biopsy samples, TB relapse, advanced age, high serum creatinine and ALT levels, and decreased duration of isoniazid use were significantly related with mortality (p < 0.05). This is the first international study on TBP and is the largest case series to date. We suggest that using the mortality predicting model will allow early identification of high-risk patients likely to die of TBP.

Safety of Surgery Among Asymptomatic SARS-CoV-2 PCR-Positive Patients: A Single-Center Retrospective Cohort Study.

BACKGROUND: Screening with SARS-CoV-2 PCR tests is recommended for all patients undergoing surgery under general anesthesia, and elective surgery is deferred for positive patients. This study evaluated the outcomes of asymptomatic PCR-positive patients who underwent general anesthesia and surgery. METHODS: Patient data were collected from the hospital records of patients who underwent surgery between January 2021 and May 2022. Asymptomatic patients with a positive PCR test between 7 days before and 5 days after surgery were compared with controls. The cases were propensity score-matched with a 1:2 ratio to the controls. All-cause in-hospital mortality was the primary outcome of the study. RESULTS: A total of 217 asymptomatic PCR-positive patients were matched to 434 controls. In multivariate analysis, PCR-positive test results were not associated with mortality (log(OR) (95%CIs), p; 0.86 (- 0.13, 1.9), 0.09). Age and ASA score (>3) were the most significant risk factors associated with mortality. CONCLUSION: This study found that surgery among asymptomatic PCR-positive patients was not associated with increased mortality.

Effects of essential oil mixtures on expression of genes involved in lipogenesis and fatty acid oxidation in geese (Anser anser).

The use of essential oils has recently increased in the poultry sector. The aim of this study was to investigate the effects of essential oil mixture (juniper, mint, oregano and rosemary oil) on fatty acid oxidation and lipogenic gene expression in geese. Research groups were formed as C (control; no additives), EK1 (0.4 ml/l essential oil mixture supplemented) and EK2 (0.8 ml/l essential oil mixture supplemented). Relative expression levels of genes included in lipogenesis (ACCα, ChREBP, FASN, LXRα and SREBP-1) expression levels of genes included in fatty acid oxidation (ACOX1, CPT1, CPT1A, PPARα and PPARγ) were measured using RT-qPCR. Group EK1 upregulates the mRNA expression levels of genes involved in lipogenesis such as ACCα, ChREBP and SREBP-1, while it downregulates the mRNA expression in levels of all genes involved in fatty acid oxidation. Group EK2 increases the mRNA expression levels of genes involved in lipogenesis such as ACCα, FASN and SREBP-1, while it decreased mRNA expression at the levels of all genes involved in fatty acid oxidation, as in the other group. In the study, adding an essential oil mixture to drinking water is predicted to increase fatty liver because it upregulates genes related to fat synthesis (lipogenesis) and downregulates genes related to fat degradation (fatty acid oxidation).

Anxiety and Depression among People Living with HIV During the COVID-19 Pandemic: A Face-to-Face Survey from Turkey.

BACKGROUND: During the COVID-19 pandemic, there have been some difficulties in the routine care of people living with HIV (PLWH). SUBJECTS AND METHODS: We aimed to evaluate the impact of COVID-19 on mental health of PLWH and their use of health services. This study was conducted using the face-to-face interview method in the outpatient clinic of a university hospital, between 01.09.2020 and 30.11.2020. Hospital Anxiety and Depression Scale and survey instrument designed by the researchers investigating socio-demographic data and access to health services were used. RESULTS: The study included 217 patients, 91.7% (n=199) of whom were male. All of the patients were postponed their hospital appointments, 60.8% were concerned about not being able to contact their physician and 53% had concerned about being stigmatized if they went to the hospital. Of the participants, 27.6% had depression, 12.9% had anxiety and 8.3% had both depression and anxiety. Low income, job loss, and fear of being stigmatized were associated with depression and anxiety. Lower level of education, discontinuation of medications and lack of opportunity to work remotely were associated with depression, while history of psychiatric illness, worry about not being able to contact their physician and cessation of antiretroviral therapy were associated with higher anxiety levels. CONCLUSION: It is important to develop strategies ensuring the continuity of care for PWLH and identify and support those with a higher mental health impact.

Tocilizumab treatment in severe COVID-19: a multicenter retrospective study with matched controls.

Coronavirus disease-2019 (COVID-19) associated pneumonia may progress into acute respiratory distress syndrome (ARDS). Some patients develop features of macrophage activation syndrome (MAS). Elevated levels of IL-6 were reported to be associated with severe disease, and anti-IL-6R tocilizumab has been shown to be effective in some patients. This retrospective multicenter case-control study aimed to evaluate the efficacy of tocilizumab in hospitalized COVID-19 patients, who received standard of care with or without tocilizumab. Primary outcome was the progression to intubation or death. PSMATCH (SAS) procedure was used to achieve exact propensity score (PS) matching. Data from 1289 patients were collected, and study population was reduced to 1073 based on inclusion-exclusion criteria. The composite outcome was observed more frequently in tocilizumab-users, but there was a significant imbalance between arms in all critical parameters. Primary analyses were carried out in 348 patients (174 in each arm) after exact PS matching according to gender, ferritin, and procalcitonin. Logistic regression models revealed that tocilizumab significantly reduced the intubation or death (OR 0.40, p = 0.0017). When intubation is considered alone, tocilizumab-users had > 60% reduction in odds of intubation. Multiple imputation approach, which increased the size of the matched patients up to 506, provided no significant difference between arms despite a similar trend for intubation alone group. Analysis of this retrospective cohort showed more frequent intubation or death in tocilizumab-users, but PS-matched analyses revealed significant results for supporting tocilizumab use overall in a subset of patients matched according to gender, ferritin and procalcitonin levels.

Foodborne streptococcal tonsillopharyngitis outbreak in a hospital.

OBJECTIVE: Group A beta-haemolytic streptococci (GAS), which are responsible for most cases of acute bacterial tonsillopharyngitis, are transmitted from person to person and may rarely cause foodborne outbreaks. This study aims to report the epidemic caused by GAS in our hospital and to draw attention to the explosive outbreaks of the bacteria. METHODS: Acute tonsillopharyngitis was seen in 201 of 450 hospital employees who ate in the hospital cafeteria on 4-5 June 2015. RESULTS: GAS was detected in 106 (68%) of 157 cases and in 40 (63.5%) of 62 throat culture samples. The attack rate was 44.7%. The most suspected source of the outbreak was a food handler who had been showing signs of streptococcal tonsillopharyngitis for six days, and perhaps the food prepared by these staff. CONCLUSION: It should not be forgotten that GAS can cause explosive outbreaks by infecting food through hand lesions or mouth secretions of food service personnel.

Rifampin-accompanied antibiotic regimens in the treatment of prosthetic joint infections: a frequentist and Bayesian meta-analysis of current evidence.

Prosthetic joint infections cause serious morbidity and mortality among joint arthroplasty patients. Rifampin-accompanied antibiotic regimens are recommended for gram-positive infections. This study aimed to combine current evidence supporting the rifampin supplement to an effective antibiotic in the treatment of prosthetic joint infections. We conducted a random-effects meta-analysis with frequentist and Bayesian approaches. A total of 13 studies, all observational, were included in the final analysis. The predominant bacteria in eight, two, and three studies were Staphylococcus spp., Propionibacterium spp., and Streptococcus spp., respectively. We pooled data from 568 patients in the staphylococcus subset (OR, 1.18; 95% CIs, [0.76; 1.82]; I2 = 23%) and data from 80 patients in the propionibacterium subset (REM OR, 1.61; 95% CIs [0.58; 4.47]; I2 = 0%). Both were insignificant with little heterogeneity. We pooled data from 483 patients in the streptococcus subset; the pooled estimate in this subset favored the use of rifampin supplemented regimens (1.84; [0.90; 3.76]) with moderate to high unaccounted heterogeneity (I2 = 57%). Bayesian random-effects models produced a posterior probability density indicating that future studies will not favor rifampin supplementation in Staphylococcus infections (µ, 0.074; τ, 0.570; 89% HPD, [- 0.48; 0.54]). Bayesian posterior distribution in the Streptococcus subset displayed a tendency toward rifampin supplementation. Studies had a substantial selection bias. Available evidence did not encourage rifampin-accompanied regimens for staphylococcal infections.

A novel approach to managing COVID-19 patients; results of lopinavir plus doxycycline cohort.

This manuscript aims to present a treatment algorithm we applied to manage COVID-19 patients admitted to our hospital. During the study period, 2043 patients with suspected COVID-19 were admitted to the emergency department. Molecular tests indicated that 475 of these patients tested positive for COVID-19. We administered hydroxychloroquine plus doxycycline to mild cases (isolated at home) for 3 days and lopinavir plus doxycycline to moderate and severe cases (hospitalized) for 5 days. The overall case fatality rate was 4.2% (20/475).

Clinicopathological profile of gastrointestinal tuberculosis: a multinational ID-IRI study.

Data are relatively scarce on gastro-intestinal tuberculosis (GITB). Most studies are old and from single centers, or did not include immunosuppressed patients. Thus, we aimed to determine the clinical, radiological, and laboratory profiles of GITB. We included adults with proven GITB treated between 2000 and 2018. Patients were enrolled from 21 referral centers in 8 countries (Belgium, Egypt, France, Italy, Kazakhstan, Saudi Arabia, UK, and Turkey). One hundred four patients were included. Terminal ileum (n = 46, 44.2%), small intestines except terminal ileum (n = 36, 34.6%), colon (n = 29, 27.8%), stomach (n = 6, 5.7%), and perianal (one patient) were the sites of GITB. One-third of all patients were immunosuppressed. Sixteen patients had diabetes, 8 had chronic renal failure, 5 were HIV positive, 4 had liver cirrhosis, and 3 had malignancies. Intestinal biopsy samples were cultured in 75 cases (78.1%) and TB was isolated in 65 patients (86.6%). PCR were performed to 37 (35.6%) biopsy samples and of these, 35 (94.6%) were positive. Ascites samples were cultured in 19 patients and M. tuberculosis was isolated in 11 (57.9%). Upper gastrointestinal endoscopy was performed to 40 patients (38.5%) and colonoscopy in 74 (71.1%). Surgical interventions were frequently the source of diagnostic samples (25 laparoscopy/20 laparotomy, n = 45, 43.3%). Patients were treated with standard and second-line anti-TB medications. Ultimately, 4 (3.8%) patients died and 2 (1.9%) cases relapsed. There was a high incidence of underlying immunosuppression in GITB patients. A high degree of clinical suspicion is necessary to initiate appropriate and timely diagnostic procedures; many patients are first diagnosed at surgery.

The clinical findings and outcomes of symptomatic pregnant women diagnosed with or suspected of having coronavirus disease 2019 in a tertiary pandemic hospital in Istanbul, Turkey.

AIM: To observe the clinical course of symptomatic pregnant women diagnosed with or suspected of having COVID-19. METHODS: This study analyzed the clinical and laboratory results of 27 patients with real-time polymerase chain reaction (RT-PCR)-confirmed COVID-19 and 25 patients with a suspected COVID-19 diagnosis based on their symptoms and chest computed tomography (CT) findings. The patients' coagulation parameters and acute-phase reactants were evaluated both before and after treatment. The maternal and neonatal outcomes were also reviewed. RESULTS: The mean duration of hospitalization was 6.1 ± 3 days. The gestational age of the patients ranged from 6w2d to 40w2d. Thirty-five patients' CT scan findings suggested viral pneumonia. Four patients delivered vaginally, and 10 patients underwent a cesarean section during the study period. Four of the cesarean deliveries were indicated due to COVID-19 hypoxemia-related fetal distress. Four patients were admitted to the intensive care unit (ICU) after the cesarean section. CONCLUSION: Early hospitalization and medical treatment can alleviate symptoms, improve the clinical course and reduce the need for ICU in symptomatic pregnant patients with suspected or confirmed COVID-19. Chest CT scans are a suitable option for suspected but unconfirmed COVID-19 infection.

Effect of prophylactic central neck dissection on the surgical outcomes in papillary thyroid cancer: experience in a single center.

PURPOSE: Morbidity due to papillary thyroid carcinoma (PTC) is increased mostly due to lymph node (LN) metastases, which lead to reoperations and complications associated with these operations. The aim is to compare the outcomes of PTC having total thyroidectomy and prophylactic central lymph node dissection (TT + PCND) with patients having total thyroidectomy (TT) alone. METHODS: This study is a retrospective cohort analysis of 358 PTC patients that were operated by a single surgeon in a single center. Data about the patients were extracted from the medical records. RESULTS: Of the patient cohort, 258 patients had TT + PCND (42.5 ± 11.3 years) and 100 patients (41.2 ± 11.9 years) had only TT. Total number of LN extracted in the TT + PCND group was 8.1 ± 6.9. The mean number of metastatic LN were 2.2 ± 1.9. Percentage of patients that had RAI were less in the TT + PCND group compared to the TT group. Seven patients (2.7%) in the TT + PCND group and 19 (19.0%) in TT group had recurrent disease (p < 0.0001). Of the complications, only transient hypoparathyroidism was increased in TT + PCND group compared to TT group (26.7% vs 10%, p < 0.0001). CONCLUSION: TT + PCND performed by an experienced surgeon seems to decrease the number of LN recurrences, and the need for reoperations.

Effects of bergamot (Citrus bergamia) peel oil-supplemented diets on growth performance, haematology and serum biochemical parameters of Nile tilapia (Oreochromis niloticus).

The present study investigated the effects of dietary Citrus bergamia peel oil (CBO) on growth performance, haematological and serum biochemical responses of Nile tilapia, Oreochromis niloticus. Volatile content of C. bergamia peel oil used in study was detected with GC/MS. The 99.47% of the analysed volatile components were identified in decreasing quantities as limonene, linalool and linalyl acetate. The experimental fish were divided into four groups stocked into triplicate tanks (20 fish/tank), and fed daily with an additive-free basal diet containing 0% (CBO0), 0.5% (CBO0.5), 1.0% (CBO1), 2.0% (CBO2) of bergamot peel oil for an 8-week period. Results showed that dietary bergamot peel oil especially at 0.5 g 100 g-1 significantly increased growth performance of fish (p < 0.05). The levels of haemoglobin and haematocrit significantly increased in fish fed with CBO0.5 and CBO1 compared with the CBO0-fed group (p < 0.05), despite no significant difference was observed in CBO2 group (p > 0.05). Highest haematocrit value was found in the CBO0.5 group compared with the control group. The serum glucose of the fish fed with CBO0.5 and CBO1 feeds decreased significantly compared with the control group (p < 0.05). The highest total protein, lowest cholesterol and triglyceride in serum were observed in fish fed with bergamot oil-supplemented groups. According to the results, it was revealed that 0.5% bergamot oil supplementation to Nile tilapia diets optimizes the growth performance, feed utilization and health status related with blood parameters of the fish.

Late presentation among patients with human immunodeficiency virus infection in Turkey.

OBJECTIVE: Late presentation of the patients with human immunodeficiency virus (HIV) infection is associated with less favourable treatment responses, more accelerated clinical progression, and a higher mortality risk. Although HIV prevalence is low in Turkey, it is steadily increasing and the information about late presentation among HIV-positives is limited. We aimed to analyze the status of late presentation among HIV-positive patients in Turkey. METHODS: All newly diagnosed HIV/AIDS patients from 2003 to 2016 were enrolled in this study by five dedicated centres in Istanbul, Turkey. Demographic data, CD4+ counts, and HIV RNA were collected from medical records and were transferred to a HIV database system. Late pre- sentation was defined as presentation for care with a CD4 count < 350 cells/mm3 or presentation with an AIDS-defining event, regardless of the CD4 cell count. A medical literature search was done for the analysis of late presentation in Turkey. RESULTS: The cohort included 1,673 patients (1,440 males, median age 35 years). Among them, 847 (50.6%) had an early diagnosis, with a CD count of more than 350 cells/mm3. The remaining 826 were late presenters. Among late presenters, 427 (25.5% of all, 51.7% of late presenters) presented with advanced HIV disease. Late presenters were more elderly and less educated. The gender seemed comparable between groups. Late presentation was more likely among married patients. Early presenters were more likely among homosexuals, those diagnosed in screening studies, and in lower HIV-RNA viral load category. There has been a decreasing trend among late presenters in 2011-2016 when compared to 2003-2011 period. CONCLUSION: Current data suggest that half of HIV-infected patients present late in Turkey. In our cohort, those presented late were more elderly, less educated, married and had heterosexual intercourse. On admission, late presenters had more HIV-related diseases and were more likely in higher HIV-RNA category. In the cohort, men having sex with men were less likely late presenters. Efforts to reduce the proportion of late presentation are essential for almost every country. The countries should identify the risk factors of late presentation and should improve early diagnosis and presentation for HIV care.

N-Acetyl Cysteine Has Both Gastro-Protective and Anti-Inflammatory Effects in Experimental Rat Models: Its Gastro-Protective Effect Is Related to Its In Vivo and In Vitro Antioxidant Properties.

N-acetyl cysteine (NAC), a metabolite of sulphur-containing amino acid cysteine, is used as an antioxidant and a mucolytic agent. Therefore, we aimed to investigate anti-inflammatory and anti-ulcerative effects of NAC. We also intended to determine the relation between antiulcer effect of NAC and its antioxidant properties by biochemical evaluation. In this study a total of 15 rat groups (n = 6 per group) were used for inflammation and ulcer experiments. Anti-inflammatory effects of NAC have been investigated on six rat groups with carrageenan (CAR)-induced paw oedema model. Antiulcer effects of NAC have been investigated on 24 h fasted nine rat groups with IND-induced ulcer model in the presence of positive (LAN, RAN, FAM, and OMEP), negative (untreated IND group) and intact control groups. In biochemical analyses of stomach tissues; glutathione S-transferase (GST), catalase (CAT), myeloperoxidase (MPO), and superoxide dismutase (SOD) enzyme activities and lipid peroxidation (LPO) and the glutathione (GSH) levels were determined. All doses of NAC exerted significant anti-inflammatory effect; even the effect of 900 mg/kg NAC was similar with that of DIC and IND. In gastric tissues NAC administration decreased the level of LPO and activity of CAT, which were increased by IND. Furthermore, NAC increased the GSH level and SOD and GST activities, which decreased in ulcerous stomach tissues. Only MPO activity increased in both IND and NAC groups when compared to healthy rat group. We determined that NAC has both anti-inflammatory and anti-ulcerative effects.

Infantile granular parakeratosis: cytologic examination of superficial scrapings as an aid to diagnosis.

Granular parakeratosis (GP) is a benign disorder of keratinization presenting with unilateral or bilateral red to brown hyperkeratotic plaques and papules at the intertriginous areas. The first pediatric case of GP was reported in 2002, and only a few cases have been reported since. Although the exact etiology of GP is unknown, it is thought that certain environmental factors compromise the epidermal barrier and lead to proliferation and altered maturation of the epidermis in predisposed individuals. The histopathology is diagnostic and reveals parakeratosis together with retention of keratohyalin granules within a disproportionately thickened stratum corneum and usually the preservation of stratum granulosum. Herein we report seven cases of infantile GP, six of which also had atopic dermatitis. Cytologic examination confirmed our clinical diagnosis by demonstrating the retention of keratohyalin granules and preservation of the nuclei from the superficial scrapings of the lesions, which we propose as a novel diagnostic technique. In all seven cases the lesions developed after the overuse of topical products and resolved with avoidance of their excessive use. We propose that atopic skin may be more prone to develop GP because the epidermal barrier is disrupted, resulting in the enhanced transepidermal penetration of topical products. In conclusion, GP should be included in the differential diagnosis of diaper area eruptions, especially in atopic children. Cytologic examination of superficial scrapings of the lesions can easily confirm the diagnosis of GP.
