Biofouling control in reverse osmosis membranes (ROMs) is challenging due to the high cost of treatments, and reduction in the life of ROMs. This study characterizes the biofouling in the ROMs from a desalination plant and reports its effective removal using the supernatant obtained from Alteromonas sp. strain Ni1-LEM. The characterization of the bacterial community revealed that the most abundant taxa in ROMs were the genera Fulvivirga and Pseudoalteromonas, and unclassified species of the families Flavobacteriaceae and Sphingomonadaceae. This bacterial community significantly decreased upon treatment with the supernatant from Alteromonas sp. Ni1-LEM, resulting in the prevalence of the genus Pseudoalteromonas. Furthermore, this bacterial supernatant significantly inhibited cell adhesion of seven benthic microalgae isolated from ROMs as well as promoting cell detachment of the existing microbial biofilms. The study showed that the extracellular supernatant modified the conformation of extracellular polymeric substances (EPS) in the biofouling of ROMs without any biocidal effects.Background The 2019 community-acquired pneumonia guidelines recommend using recent respiratory cultures and locally validated epidemiology plus risk factor assessment to determine empirical coverage of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. Objective To develop a methodology for evaluating local epidemiology and validating local risk factors for P aeruginosa and MRSA. Methods This multicenter, retrospective cohort evaluated adult patients admitted for pneumonia. Risk factors for MRSA and P aeruginosa were evaluated using multivariable logistic regression and reported as adjusted odds ratios (aORs). Results There were 10 723 cases evaluated. Lung abscess/empyema had the highest odds associated with MRSA (aOR = 4.24; P less then 0.0001), followed by influenza (aOR = 2.34; P = 0.01), end-stage renal disease (ESRD; aOR = 2.09; P = 0.006), illicit substance use (aOR = 1.7; P = 0.007), and chronic obstructive pulmonary disease (COPD; aOR = 1.26; P = 0.04). For P aeruginosa, the highest odds were in bronchiectasis (aOR = 6.13; P less then 0.0001), lung abscess/empyema (aOR = 3.36; P = 0.005), and COPD (aOR = 1.84; P less then 0.0001). Isolated COPD without other risk factors did not pose an increased risk of either organism. Conclusion and Relevance Influenza, ESRD, lung abscess/empyema, and illicit substance use were local risk factors for MRSA. Bronchiectasis and lung abscess/empyema were risk factors for Pseudomonas. COPD was associated with MRSA and Pseudomonas. However, isolated COPD had similar rates of MRSA and Pseudomonas pneumonia compared with the total population. This study established a feasible methodology for evaluating local risk factors.Nepal is at a high risk of increasing COVID-19 cases through people who recently returned to Nepal from other countries. The health care system of Nepal is fragile, and the country is not having the necessary infrastructure to cope with an increasing number of infections and pandemic situations.Case (description) A 74 years old Caucasian suffering from chronic kidney disease presented with progressive asthenia and diffuse myalgia. It was revealed that the patient used three different rosuvastatin-containing preparations in a total daily dose of 120 mg for 76 days. Laboratory investigations revealed a marked elevation of serum urea, creatinine, myoglobin, creatine kinase (CK) and transaminases. Two serious medication errors have been identified as possible major factors that synergistically contributed to the development of rosuvastatin-induced rhabdomyolysis. First, 40 mg of rosuvastatin dose was prescribed to the patient, although the estimation of glomerular filtration rate (eGFR) declined below 40 ml/min/1.73 m2. CPI-0610 cell line Moreover, the patient used 3 different rosuvastatin formulations simultaneously in a total dose of 120 mg/day. The heterozygous CYP2C9*1/*3 genotype and warfarin co-administration could further contribute to the development of rhabdomyolysis. A number of preventive measures, notably in drug policy, are suggested to overcome unintended intoxications. Conclusion Rosuvastatin-induced myopathy is a rare, but serious adverse effect. This case report highlights the need for a proper treatment and dose adjustment during chronic medical therapy, the need for adequate patient education and application of adequate drug policy measures in the era of fragmented health care delivery and polypragmasia.Lactobacilli use in treatment and prevention of the vaginal microflora disorders, such as bacterial vaginosis and vulvovaginal candidiasis, is highly promising. The objective of this study was is to develop formulation and technology of the extemporal Lactobacillus casei (L. casei) ІМВ В-7280-containing medicinal product in the form of vaginal pessaries. The quality control parameters were defined in accordance with the State Pharmacopeia of Ukraine (2nd edition) and included appearance, uniformity of texture, uniformity of mass and disintegration test. Lactobacilli assay was determined after preparation and within the storage period. Thus, feasible formulation and technology were selected for vaginal pessaries with an expected 6-month shelf life. The results of the hereby described research will be used for technological instruction development for extemporaneous vaginal pessaries with defined probiotic activity.Rotavirus is one of the most important causative agents of gastroenteritis in both infants and children worldwide, resulting in high mortality and morbidity, mainly in low-income, developing countries. Respective analysis of medical records of newborns hospitalized with acute gastroenteritis showed that the use of α2b-interferon in complex pharmacotherapy was characterized by faster reverse development of clinical manifestations of the disease than in patients who did not receive interferon. In our study, we also aimed to estimate the effectiveness of α2b-interferon supplementation in combination pharmacotherapy of newborns with suspected rotavirus infection. Achievement of this goal was possible with the construction of a decision tree model and determination of decision rules for inclusion of α2b-interferon supplementation into the complex pharmacotherapy. The input parameters of the model were hospitalization days of patients stratified by such signs as the presence or absence of rotavirus infection, as well as the additional inclusion of α2b-interferon supplementation in complex pharmacotherapy.
