The use of Saccharomyces cerevisiae (SC) feed additives to improve animal performance are on the increase; however, the results of the action of SC supplementation on goats performance indices are conflicting. Thus, the thrust of this meta-analysis was to examine the influence of dietary SC intervention on the growth performance, haemato-biochemical indices and ruminal fermentation characteristics of growing goats fed total mixed ration (TMR). The search conducted in Google Scholar, PubMed and Scopus databases using several keywords yielded 500 studies of which 16 full-text articles were utilised for study. Response variables were aggregated via a random-effects model. The results showed that goats fed SC experienced higher average daily gain (ADG) than the controls (as standardized mean difference, SMD = 2.14; 95% confidence interval, CI: 1.40 to 2.89). In converse, dietary SC intervention had a small impact on dry matter intake (DMI) and feed conversion ratio (FCR). Subgroup analysis demonstrated that SC type (active vs inactive) improved FCR and ADG in growing goats. Results suggested that SC preparation increased blood glucose, white blood cell (WBC), ruminal propionate and total volatile fatty acid levels. There is heterogeneity among the articles used in the study, and aspects of studied covariates explained the variation. In conclusion, this study indicated that dietary yeast can positively influence growth performance, haemato-biochemical indices, and rumen fermentation parameters of growing goats.

UNASSIGNED: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. Astrocyte swelling is a major component of hepatic encephalopathy. Thus, we hypothesised that glial fibrillary acidic protein (GFAP), the major intermediate filament of astrocytes, might facilitate early diagnosis and management. This study aimed to investigate the utility of serum GFAP (sGFAP) levels as a biomarker of CHE.
UNASSIGNED: In this bicentric study, 135 patients with cirrhosis, 21 patients with ongoing harmful alcohol use and cirrhosis, and 15 healthy controls were recruited. CHE was diagnosed using psychometric hepatic encephalopathy score. sGFAP levels were measured using a highly sensitive single-molecule array (SiMoA) immunoassay.
UNASSIGNED: In total, 50 (37%) people presented with CHE at study inclusion. Participants with CHE displayed significantly higher sGFAP levels than those without CHE (median sGFAP, 163 pg/ml [IQR 136; 268] vs. 106 pg/ml [IQR 75; 153]; p <0.001) or healthy controls (p <0.001). sGFAP correlated with results in psychometric hepatic encephalopathy score (Spearman\'s ρ = -0.326, p <0.001), model for end-stage liver disease score (Spearman\'s ρ = 0.253, p = 0.003), ammonia (Spearman\'s ρ = 0.453, p = 0.002), and IL-6 serum levels (Spearman\'s ρ = 0.323, p = 0.006). Additionally, sGFAP levels were independently associated with the presence of CHE in multivariable logistic regression analysis (odds ratio 1.009; 95% CI 1.004-1.015; p <0.001). sGFAP levels did not differ between patients with alcohol-related cirrhosis vs. patients with non-alcohol-related cirrhosis or between patients with ongoing alcohol use vs. patients with discontinued alcohol use.Conclusions: sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker.

UNASSIGNED: Bacterial infections affect survival of patients with cirrhosis. Hospital-acquired bacterial infections present a growing healthcare problem because of the increasing prevalence of multidrug-resistant organisms. This study aimed to investigate the impact of an infection prevention and control programme and coronavirus disease 2019 (COVID-19) measures on the incidence of hospital-acquired infections and a set of secondary outcomes, including the prevalence of multidrug-resistant organisms, empiric antibiotic treatment failure, and development of septic states in patients with cirrhosis.
UNASSIGNED: The infection prevention and control programme was a complex strategy based on antimicrobial stewardship and the reduction of patient\'s exposure to risk factors. The COVID-19 measures presented further behavioural and hygiene restrictions imposed by the Hospital and Health Italian Sanitary System recommendations. We performed a combined retrospective and prospective study in which we compared the impact of extra measures against the hospital standard.
UNASSIGNED: We analysed data from 941 patients. The infection prevention and control programme was associated with a reduction in the incidence of hospital-acquired infections (17 vs. 8.9%, p <0.01). No further reduction was present after the COVID-19 measures had been imposed. The impact of the infection prevention and control programme remained significant even after controlling for the effects of confounding variables (odds ratio 0.44, 95% CI 0.26-0.73, p = 0.002). Furthermore, the adoption of the programme reduced the prevalence of multidrug-resistant organisms and decreased rates of empiric antibiotic treatment failure and the development of septic states.
UNASSIGNED: The infection prevention and control programme decreased the incidence of hospital-acquired infections by nearly 50%. Furthermore, the programme also reduced the prevalence of most of the secondary outcomes. Based on the results of this study, we encourage other liver centres to adopt infection prevention and control programmes.
UNASSIGNED: Infections are a life-threatening problem for patients with liver cirrhosis. Moreover, hospital-acquired infections are even more alarming owing to the high prevalence of multidrug-resistant bacteria. This study analysed a large cohort of hospitalised patients with cirrhosis from three different periods. Unlike in the first period, an infection prevention programme was applied in the second period, reducing the number of hospital-acquired infections and containing multidrug-resistant bacteria. In the third period, we imposed even more stringent measures to minimise the impact of the COVID-19 outbreak. However, these measures did not result in a further reduction in hospital-acquired infections.

Urgent scrotal exploration is performed for segmental testicular infarction (STI) because malignant testicular tumors cannot be ruled out even when STI is suspected on color Doppler ultrasound (US). This report describes the case of a 14-year-old boy who was successfully diagnosed with STI associated with epididymitis using color Doppler US to avoid radical orchiectomy. To our knowledge, this is the first report of STI being diagnosed during puberty and managed using color Doppler US and contrast-enhanced magnetic resonance imaging-guided conservative treatment.

Adverse reaction to metal debris (ARMD) is a known complication of metal-on-metal hip arthroplasty. There has been one previously reported case of ARMD with concomitant gout in the setting of a hip arthroplasty. We report a case of ARMD with accompanying monosodium urate crystals as well as amyloid deposition in the hip of a patient who had undergone a metal-on-metal hip arthroplasty. This is the only published case to date of these 3 conditions co-existing, although it is possible that the incidence is higher since these require special diagnostic tests that are not routinely performed. It is postulated that these entities are biochemically associated with each other rather than being purely coincidental.

Delayed hemorrhage from the vaginal stump is a rare complication following hysterectomy. Most cases can be managed by vaginal packing with or without vaginal vault suturing. However, where such initial management fails, the condition is potentially life-threatening and requires immediate intervention. We report two cases successfully managed with transcatheter arterial embolization (TAE). First, a 38-year-old woman presented with lower abdominal pain 12 days after laparoscopic-assisted vaginal hysterectomy (LAVH) for a uterine myoma. Oral antibiotics were administered for pelvic infection. Two days later, she experienced increased bleeding. After failing to achieve hemostasis with vaginal vault suturing, computed tomographic angiography showed extravasation from a pseudoaneurysm in the peripheral branch of the left uterine artery. Hemostasis was achieved with TAE. Second, a 40-year-old woman presented with fever and increased abdominal pain 6 days after LAVH for severe dysplasia of the uterine cervix. Intravenous antibiotics were administered for pelvic infection. Twenty-one days after LAVH, she experienced increased bleeding. Computed tomographic angiography showed extravasation from a peripheral thin branch of the right uterine artery. Temporary hemostasis was achieved with vaginal vault suturing; however, bleeding recommenced 12 h later. Hemostasis was achieved with TAE. We conclude that endovascular management is a feasible option for intractable delayed hemorrhage after hysterectomy, when vaginal vault suturing fails to achieve hemostasis.

Measurement of the levels of serum immunoglobulin A antibody against glycopeptidolipid (GPL) core antigen, a cell surface antigen found in Mycobacterium avium complex (MAC), has been reported to be useful in the diagnosis and management of pulmonary MAC infection. However, evidence on its utility in hypersensitivity pneumonitis (HP) associated with MAC (i.e., \"hot-tub lung\") is limited. We herein report a case of HP associated with MAC in which the GPL core antibody levels were serially measured from diagnosis to treatment and thereafter. A 61-year-old man was suspected to have non-fibrotic HP based on the clinical course, laboratory findings, imaging pattern, bronchoalveolar lavage (BAL) lymphocytosis, and histopathological findings. Based on the history of whirlpool bath use, inhalation of aerosolized MAC was suspected as the cause of HP. The GPL core antibody level, measured using an enzyme-linked immunosorbent assay kit, was elevated, suggesting an immunological sensitization to MAC. A provocation test using the patient\'s whirlpool bath was positive. An identical MAC strain was isolated from the BAL fluid and bathtub. Accordingly, the patient was diagnosed with HP caused by the inhalation of aerosolized MAC from the whirlpool bath. The patient recovered after steroid treatment and discontinuation of the whirlpool bath. The GPL core antibody levels decreased with disease improvement. In conclusion, GPL core antibody levels could be elevated in HP associated with MAC and decrease with disease improvement. Thus, measurement of the GPL core antibody level may be useful for the diagnosis and management of HP associated with MAC.

UNASSIGNED: Scrub Typhus (ST) is an acute febrile illness caused by obligate intracellular bacteria of the family Rickettsia. It is often unrecognized and neglected but prevalent in tropical regions of endemic areas. The tragedy behind this diagnostic dilemma is non-specific clinical signs and symptoms, limited awareness, unavailability of diagnostic facilities, and low index of suspicion among the physicians. To address the knowledge gap, we tried to find out a proper panel of laboratory investigations to diagnose the disease and predict its progression because of the uncertainty of the course of the disease in a tertiary care hospital in western Nepal.
UNASSIGNED: This is a hospital laboratory-based prospective study conducted at Gandaki Medical College- Teaching Hospital (GMC-TH) for a period of two years. Among 988 cases of acute febrile illness, 40 seropositive cases of ST were enrolled in the study. We excluded those who did not give consent for the participation, those who were under 17 years of age, and those who had preexisting liver dysfunctions and other co-morbidities and dual seropositive with other infectious etiologies. We used descriptive statistics to analyze the data in terms of demography, clinical features, and laboratory parameters.
UNASSIGNED: Out of 988 febrile patients, we included 40 confirmed cases of ST aged between 17 and 70 years during the study-period. Maximum seropositive cases were from Tanahun district 14 (35%), with predominance among the women (70%). The cases were prevalent in the age group 30-60 years, 19 (47.5%), and in the month of October 15 (37.5%). The commonest complaints were fever in 40 (100%), headache in 20 (50%), eschar in 11 (27.5%). Laboratory parameters showed anemia in 22 (55%), hypoalbuminemia in 11 (27.5%), leukopenia in 5 (12.5%), leukocytosis in 9 (22.5%), thrombocytopenia in 13 (32.5%), raised transaminase levels, SGPT in 21 (52.5%) and SGOT in 14 (26%) ST patients.
UNASSIGNED: We found clinical and laboratory profiles in patients with ST were varied and nonspecific. However, knowledge of these findings may evoke the recognition of ST and give a clue to the progression of the disease.

Steady-calcium formula (SCF), a functional food mixture with potential of joint care, contains five major ingredients. However, the uncertain cross-reactivity among these included ingredients cannot be excluded. Hence, it is important to ensure the safety of this mixture. In this study, the safety of SCF was evaluated through in vitro genotoxicity assessment and 28-day oral toxicity study in rats. The bacterial reverse mutation test and mammalian chromosome aberration test displayed that SCF did not induce mutagenicity and clastogenicity. The 28-day repeated dose assessment of SCF in rats revealed no mortality and adverse effects in clinical signs, body weight, urinalysis, hematology, organ weight, and histopathology at all treated groups. Although some significant changes were observed in food intake and parameters of serum biochemistry at the highest dose in males, they were not dose-related and considered to be within normal range. These findings indicate that SCF does not possess genotoxic potential and no obvious evidence of subacute toxicity. These results demonstrate for the first time that the genotoxicity and subacute toxicity for SCF are negative under our experimental conditions and the no observed adverse effect level (NOAEL) of SCF may be defined as at least 5470 mg/kg/day.

The subchronic toxicity of oral L-tryptophan produced by fermentation with metabolically engineered Corynebacterium glutamicum was evaluated in Sprague-Dawley rats. Doses of 0, 500, 1000, and 2000 mg/kg/day were administered to groups of 10 male and 10 female rats for 90 days. For the groups administered 0 and 2000 mg/kg/day, an additional 5 male and 5 female rats were tested as a recovery group. No adverse effects associated with the test substance were observed in all rats during the 90-day administration of the product, irrespective of dose, and at 4 weeks of recovery at dosages of 0 and 2000 mg/kg/day. Furthermore, histochemical and immunohistochemical analyses for L-tryptophan-associated eosinophilia-myalgia syndrome (EMS) did not reveal significant changes in both sexes of groups administered 0 or 2000 mg/kg/day. Based on these results, it could be concluded that there were no significant adverse effects related to the test substance in all animals; therefore, dried L-tryptophan fermentation product can be used as feed additive material.
