Giardia duodenalis is a major gastrointestinal parasite of humans and animals across the globe. It is also of interest from an evolutionary perspective as it possesses many features that are unique among the eukaryotes, including its distinctive binucleate cell structure. While genomic analysis of a small number of isolates has provided valuable insights, efforts to understand the epidemiology of the disease and the population biology of the parasite have been limited by the molecular tools currently available. We review these tools and assess the impact of affordable and rapid genome sequencing systems increasingly being deployed in diagnostic settings. While these technologies have direct implications for public and veterinary health, they will also improve our understanding of the unique biology of this fascinating parasite.
To evaluate the efficacy of daily consumption of fortified yogurt with beta-Hydroxy beta-Methyl Butyrate (HMB) and vitamins D and C on measures of sarcopenia, inflammation, and quality of life in sarcopenic older adults.
In this 12-week randomized double-blind controlled trial, participants received either yogurt fortified with 3g HMB, 1000 IU vitamin D, and 500mg vitamin C in the intervention group (n=33) or plain yogurt in the control group (n=33).
A total of 66 older adults with sarcopenia recruited from the community in Shiraz, Iran.
Body composition, muscle strength, and functionality were measured using Dual-energy-X-ray Absorptiometry (DXA), hydraulic handgrip dynamometer, and usual gait speed, respectively. Serum concentrations of vitamin D, insulin-like growth factor-1 (IGF-1), C-reactive protein (hs-CRP), malondialdehyde, and insulin were measured at baseline and after 12weeks. Health-related quality of life (HRQoL) was also evaluated using SF-12 questionnaire.
Consumption of fortified yogat specific nutritional interventions alone could be beneficial, especially for those who are unable to exercise.
A novel dairy product fortified with HMB, vitamin D, and vitamin C not only could enhance muscle strength and functionality, but also modulate anabolic and inflammatory conditions as well as quality of life. This study suggested that specific nutritional interventions alone could be beneficial, especially for those who are unable to exercise.
Globally, mistreatment during childbirth remains a powerful deterrent to skilled birth utilization.
We determined the perpetrated and witnessed experiences of mistreatment and Respectful Maternity Care (RMC) among maternal health providers in a tertiary hospital in Nigeria.
A cross-sectional study was conducted among 156 maternal health providers in a tertiary hospital in Nigeria. Information was collected using semi-structured, self-administered questionnaires, and 3 focus group discussions. Quantitative and qualitative data analyses were performed using SPSS version 20 and thematic analysis respectively.
Most respondents were males (64.1%) and doctors (74.4%) with mean age of 31.97±6.82. Two-fifths (39.1%) and 73.1% of the respondents had ever meted out or witnessed disrespectful and abusive care to women during childbirth respectively. Verbal abuse and denial of companionship in labour were major mistreatments reported qualitatively and quantitatively. About a third of the respondents mistreated wooviders. We recommend intensification of provider capacity building on RMC with special focus on older practitioners and the provision of supportive work environments that encourage respectful maternal care practices.
There occurs huge heterogeneity in clinical outcomes for patients with epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC) treated with EGFR tyrosine kinase inhibitors (EGFR-TKIs). The purpose of this study was to indicate genetic biomarkers predicting primary resistance of EGFR-TKIs in these patients.
Using a next-generation sequencing panel with 168 cancer-related genes, matched tumor biopsy and plasma samples before treatments from patients with NSCLC were analyzed. Patients taking EGFR-TKIs were followed-up with imaging examination. Correlation of co-alterative genes with progression-free survival (PFS) was analyzed.
Of the 48 patients treated with EGFR-TKIs, 46 (95.83%) had at least 1 genetic co-variant beyond EGFR mutation. Multivariate analysis indicated that RB1, PIK3CA, and ERBB2 co-alterations, rather than number of co-alterative genes, were independently associated with poorer PFS. Grouping patients by specific gene status showed best likelihood ratio χ
, Akaike information criterion, and Harrell concordance index. The median PFS for patients in group A (less genetic co-variations and wild specific genes), group B (more genetic co-variations and wild specific genes), group C (less genetic co-variations and altered specific genes), and group D (more genetic co-variations and altered specific genes) were 10.4, 9.13 (vs. group A; P= .3112), 6.33 (vs. group B; P= .0465), and 3.90 (vs. group C; P= .0309) months, respectively.
This study revealed a high concomitant genetic alteration rate in patients with EGFR-mutated NSCLC. Colforsin manufacturer Specific gene variants were more important than number of altered genes in predicting poor PFS, and may help select patients needing new treatment strategies.

Antiangiogenic agents combined with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are considered potentially effective biologically synergistic drug combinations for EGFR-mutant advanced non-small-cell lung cancer (NSCLC), although some controversy remains. The European Commission has approved the use of bevacizumab plus erlotinib as first-line treatment of EGFR-mutated NSCLC; however, it has not yet been approved by the U.S. Food and Drug Administration. Recently, several phase III, randomized controlled trials of combinations of antiangiogenic agents and EGFR-TKIs have been reported. These studies have not yet been included in any previous meta-analysis.
We performed a meta-analysis to compare antiangiogenic agents plus EGFR-TKIs versus EGFR-TKIs alone for treatment of EGFR-mutant NSCLC. The main outcomes were progression-free survival (PFS), overall survival (OS), the objective response rate (ORR), and adverse events (AEs).
We identified 9 previous reports of 6 randomized controlled trials and 1 prospective cohort study, involving 1295 patients.
