Effects of Probiotics on Chemotherapy-induced Diarrhea.

Chemotherapy-induced diarrhea (CID) is a common adverse event in cancer patients, which, unless treated, may lead to drug discontinuation and treatment failure. Some probiotics such as Lactobacillus, Bifidobacterium, and Saccharomyces species have been gaining clinical attention in alleviating chemotherapy-induced adverse events including diarrhea. This comprehensive review provides an overview and discusses preventive approaches of probiotics with respect to CID in several types of cancers. The potential mechanisms of probiotics may comprise regulation of intestinal microbiota, modulation of immune functions, or reduction of proinflammatory cytokines. The efficacy and safety precautions of probiotics in immunocompromised cancer patients are discussed. The non-pharmacological strategy using probiotics could reduce the use of anti-diarrheal or antibiotic agents. Some individuals experienced shorter length of hospital stay, better gastrointestinal function, and reduced incidence of chemotherapy dose reduction after probiotic administration. Nonetheless, some studies failed to report the benefits of probiotics in certain patients. This review also highlights preventive protocols and therapeutic implications by considering the potential influencing factors, particularly types of probiotic strains, dosages of probiotics, duration of their administration, patients' tolerability, and variations in probiotic effects over the cancer stages.

Nutritional Support with Omega-3 Fatty Acids in Burn Patients: A Systematic Review with Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: In burn patients, the profound effect of nutritional support on improved wound healing and a reduced rate of hospitalization and mortality has been documented. Fish oil as a primary source of omega-3 fatty acids in nutritional support may attenuate the inflammatory response and enhance immune function; however, unclear effects on the improvement of clinical outcomes in burn patients remain. METHODS: The systematic literature review was conducted by searching the electronic databases: Cochrane Library, PubMed, ScienceDirect, and Scopus to assess the randomized controlled trials of nutritional support with omega-3 fatty acids compared to control diets in patients that presented with burns from any causes. RESULTS: Seven trials were included in this meta-analysis. We found no significant differences in length of stay (LOS) (p = 0.59), mortality (p = 0.86), ventilation days (p = 0.16), gastrointestinal complications-e.g., constipation and diarrhea (p = 0.73)-or infectious complications-e.g., pneumonia and sepsis (p = 0.22)-between the omega-3-fatty-acid-receiving group and the control/other diets group. CONCLUSIONS: We did not find a benefit of omega-3 support in reducing the various complications, mortality and LOS in burn patients. Further studies are necessary to find the effect of nutritional support with omega-3 fatty acids over low-fat diets in this population.

A systematic review of community pharmacist practices in complementary medicine

Background: The people who use complementary medicines (CMs) believe that these medicines are safe and harmless. They could easily access CMs like herbal or traditional medicines in community pharmacies. Therefore, community pharmacists are important professionals in advising the safe choices of CMs and providing evidence-based information for customers to decrease adverse effects of CMs. Objectives: To systematically review knowledge, attitude, and practices of community pharmacists about CMs, and the factors associated with CM practices of dispensing, recommending and counseling patients, and answering the patients’ queries. Method: An electronic search was performed with four databases: PubMed, Scopus, SpringerLink and ScienceDirect, from 1990 to 19th May 2022. The inclusion criteria were studies 1) about knowledge, attitude, and/or practices of community pharmacists about CMs, 2) written in English, 3) conducted with quantitative methods, and 4) able to retrieve full text.

Pharmacokinetic Outcomes of the Interactions of Antiretroviral Agents with Food and Supplements: A Systematic Review and Meta-Analysis.

Because pharmacokinetic changes in antiretroviral drugs (ARV), due to their concurrent administration with food or nutritional products, have become a clinical challenge, it is necessary to monitor the therapeutic efficacy of ARV in people living with the human immunodeficiency virus (PLWH). A systematic review and meta-analysis were conducted to clarify the pharmacokinetic outcomes of the interaction between supplements such as food, dietary supplements, and nutrients, and ARV. Twenty-four articles in both healthy subjects and PLWH were included in the qualitative analysis, of which five studies were included in the meta-analysis. Food−drug coadministration significantly increased the time to reach maximum concentration (tmax) (p < 0.00001) of ARV including abacavir, amprenavir, darunavir, emtricitabine, lamivudine, zidovudine, ritonavir, and tenofovir alafenamide. In addition, the increased maximum plasma concentration (Cmax) of ARV, such as darunavir, under fed conditions was observed. Area under the curve and terminal half-life were not significantly affected. Evaluating the pharmacokinetic aspects, it is vital to clinically investigate ARV and particular supplement interaction in PLWH. Educating patients about any potential interactions would be one of the effective recommendations during this HIV epidemic.

Deterioration of Nutritional Status and Its Negative Association with Depression Among Older HIV-Infected Asian Population: A Four-Year Longitudinal Study.

There is limited evidence about the long-term changes in nutritional status among the elderly people living with human immunodeficiency virus (PLWH). We aimed to investigate the changes in nutritional status and related factors over 4 years in the elderly PLWH. The longitudinal study was conducted prospectively among 250 PLWH, 50 years of age and older, receiving antiretroviral therapy (ART). The Mini Nutritional Assessment (MNA) and Thai Depression Scale (TDS) to assess nutritional status and depression, respectively, were performed at the outpatient clinic both at baseline and 4-year follow-up. Majority were male (60.8%) with median age of 58 years. The median CD4 was 612.5 cells/mm3 and 98% had HIV RNA <50 copies/mL. Median duration of ART was 20 years. Median body mass index was 23.1 kg/m2. The most common ART were rilpivirine (45.2%) and dolutegravir (18.8%). Fifty-one patients (20.4%) deteriorated in nutritional status and mean MNA scores declined (25.8 vs. 24.8, p < .001) at follow-up period. In multivariate analysis, high TDS scores (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.17-1.52), polypharmacy (OR, 1.35; 95% CI, 1.10-1.65), and high-density lipoprotein cholesterol (HDL-C) levels (OR, 1.04; 95% CI, 1.01-1.07) were associated factors of deterioration in nutritional status. In this 4-year longitudinal follow-up, 20% of the aging PLWH have deterioration of nutritional status. High TDS scores (depression), polypharmacy, and high HDL-C were significantly associated with declining nutritional status. Our findings highlight the importance of screening and monitoring nutritional and depression status in routine HIV treatment and care for geriatric HIV-infected population.

A systematic review of community pharmacist practices in complementary medicine.

Background: The people who use complementary medicines (CMs) believe that these medicines are safe and harmless. They could easily access CMs like herbal or traditional medicines in community pharmacies. Therefore, community pharmacists are important professionals in advising the safe choices of CMs and providing evidence-based information for customers to decrease adverse effects of CMs. Objectives: To systematically review knowledge, attitude, and practices of community pharmacists about CMs, and the factors associated with CM practices of dispensing, recommending and counseling patients, and answering the patients' queries. Method: An electronic search was performed with four databases: PubMed, Scopus, SpringerLink and ScienceDirect, from 1990 to 19th May 2022. The inclusion criteria were studies 1) about knowledge, attitude, and/or practices of community pharmacists about CMs, 2) written in English, 3) conducted with quantitative methods, and 4) able to retrieve full text. Results: Twenty-three studies were included in this systematic review. Some studies showed that less than half of the pharmacists asked or counselled about CMs to their patients and answered the patients' queries about CMs. Only 20% of the pharmacists did report CM side-effects. Training or education about CMs was a common factor associated with the CM practice of dispensing, recommending, counseling, and answering the patients' queries about CMs. CMs recommended most by community pharmacists were vitamins & minerals, food or dietary supplements, fish oil and probiotics. The most common dispensed CMs were vitamins & minerals, herbs, food or dietary supplements, fish oil and essential oils. Lacks of reliable information sources and scientific evidence were common barriers for the CM practices. Being less expensive than conventional medicines motivated the pharmacists to recommend and discuss about CMs. The community pharmacists that participated in included studies suggested strengthening CM trainings and highlight the pharmacist role in CM therapy. Conclusion: A high percentage of community pharmacists did dispense CMs to their patients, while a low percentage of the pharmacists did report CM side effects. Pharmacists were most comfortable recommending and responding the patients' CM queries. Training or education about CMs associated with CM dispensing, recommending, discussing, and answering the patients' queries about CMs was recommended.

Nutritional assessment in the HIV-infected older population receiving antiretroviral therapy.

Malnutrition is a pronounced public health issue which often seems underestimated in the older people living with HIV (PLWH) virus infection. PLWH are highly vulnerable to nutritional problems resulting from agingrelated deterioration, disease itself, and adverse effects of antiretroviral therapy (ART). The comprehensive nutritional assessments are necessary to perform routinely in this population to monitor and provide appropriate interventions to reduce comorbid conditions. In this review, we focus on the untoward impacts of malnutrition and nutritional assessments on the morbidity and mortality in the older PLWH. Some predictive factors of nutritional status in this group of patients are discussed. We propose the important components for nutrition assessment tool for older PLWH on ART. Highlighted issue is the need for developing uniform standardized tools for the early diagnosis of malnutrition in this population. Applications of the nutritional assessments, proper nutritional interventions, and regular monitoring of nutritional status in older PLWH liv-ing in every clinical setting may help the patients get better well-being.

Antiretroviral Therapy-Associated Metabolic Complications: Review of the Recent Studies.

The extensive utilization of antiretroviral therapy (ART) has successfully improved human immunodeficiency virus (HIV)-associated complications. The incidence of opportunistic infections is decreased by the viral load suppression and the CD4 count promotion. However, metabolic complications, commonly bone demineralization, lipodystrophy, and lactic acidosis, are arising following the adaptation of long-term ART. The events are not drug-specific, but the severity and incidence individually vary depending upon classes of drugs. Such concerning occurrences may lead to discontinuation of current therapy or switching to another regimen with fewer adverse effects. The purpose of this review is to demonstrate the common metabolic abnormalities associated with each class of widely used ART in people living with HIV (PLHIV). Electronic databases such as PubMed, ScienceDirect, Scopus, Google Scholar, SciFinder, and Web of Science were used for the literature search. A better understanding of ART-associated metabolic adverse effects is helpful in various clinical settings so that therapists may optimize treatments in this population.
