Chloroacetamide herbicides are widely used to control weeds globally. In this study, three acetochlor-degrading mixed cultures using nitrate, sulfate, and ferric iron as electron acceptors were isolated and determined for their degradation under anaerobic conditions. The degradation rates of all mixed pure cultures in a mineral medium were not much different at 1 µM, while the rates at 50 µM were in the order: mixed culture using nitrate > sulfate > ferric iron as electron acceptors, giving 6.

Article Synopsis
  • - The study evaluated surface water quality in Dong Thap province from 2013 to 2023, utilizing methods like water quality index, PCA, and cluster analysis to analyze various water parameters.
  • - Findings revealed high levels of Escherichia coli in 95.5% of samples and significant exceedances in other pollutants, though the presence of heavy metals like As, Cu, and Pb decreased by 2022-2023.
  • - Overall, the water quality showed improvement trends, with 70% of monitoring sites considered good quality by 2023, highlighting the need for effective policymaking to address pollution sources related to human activities and hydrological changes.

Background: Approximately 20% of adults in Vietnam have hypertension, and management of this chronic condition remains challenging. This study aimed to assess the effectiveness of a multicomponent intervention in reducing blood pressure (BP) in adults with uncontrolled hypertension.

Methods: This cluster randomised controlled trial was conducted in sixteen communities (8 intervention and 8 comparison) in a rural setting in Vietnam (2017-2022).

Background: Vietnam is experiencing an increasing prevalence of hypertension in its adult population. In addition to medical therapy, modifying adverse lifestyle practices is important for effective blood pressure control. There are limited data on unhealthy lifestyle practices in patients with chronic diseases, however, particularly among hypertensive patients living in rural Vietnam.

Between 2010 and 2011, stakeholders implemented a multi-faceted community-based intervention in response to the escalating issue of uncontrolled hypertension in Hung Yen province, Vietnam. This initiative integrated expanded community health worker services, home blood pressure self-monitoring, and a unique "storytelling intervention" into routine clinical care. From the limited societal perspective, our study evaluates the cost-effectiveness of this intervention using a Markov model with a one-year cycle over a lifetime horizon.

Pretilachlor and safener fenclorim are the main components of herbicides widely applied to control weeds. Although some pure cultures of bacteria and fungi which degraded these compounds under aerobic conditions were isolated, no isolated pretilachlor- and fenclorim-degrading bacterial strains under anaerobic condition had been available. In this study, the degradation of these compounds and the effects of them on bacterial community structures were investigated under anaerobic conditions.

Article Synopsis
  • Orbital ischemic syndrome is a rare condition characterized by symptoms like acute loss of vision, eye swelling, and paralysis, often following issues with blood flow to the eye.
  • A case study details a 57-year-old man who experienced this syndrome after a mechanical thrombectomy for an occluded internal carotid artery following a stroke.
  • Despite treatment with steroids and hyperosmolar agents, the patient recovered but continued to suffer from permanent vision loss in the affected eye.

Cardiovascular diseases are the leading causes of morbidity and mortality worldwide, but implementation of evidence-based interventions for risk factors such as hypertension is lacking, particularly in low and middle income countries (LMICs). Building implementation research capacity in LMICs is required to overcome this gap. Members of the Global Research on Implementation and Translation Science (GRIT) Consortium have been collaborating in recent years to establish a research and training infrastructure in dissemination and implementation to improve hypertension care.

Purpose: Following curative-intent therapy of lung cancer, many survivors experience dyspnea and physical inactivity. We investigated the feasibility, acceptability, safety, and potential efficacy of inspiratory muscle training (IMT) and walking promotion to disrupt a postulated "dyspnea-inactivity" spiral.

Methods: Between January and December 2022, we recruited lung cancer survivors from Kaiser Permanente Colorado who completed curative-intent therapy within 1-6 months into a phase-IIb, parallel-group, pilot randomized trial (1:1 allocation).

Objectives: To inform personalised home-based rehabilitation interventions, we sought to gain in-depth understanding of lung cancer survivors' (1) attitudes and perceived self-efficacy towards telemedicine; (2) knowledge of the benefits of rehabilitation and exercise training; (3) perceived facilitators and preferences for telerehabilitation; and (4) health goals following curative intent therapy.

Design: We conducted semi-structured interviews guided by Bandura's Social Cognitive Theory and used directed content analysis to identify salient themes.

Setting: One USA Veterans Affairs Medical Center.

Fatigue is the most common symptom among cancer survivors. Cancer-related fatigue (CRF) may occur at any point in the cancer care continuum. Multiple factors contribute to CRF development and severity, including cancer type, treatments, presence of other symptoms, comorbidities, and medication side effects.

The human monkeypox virus is a zoonotic orthopoxvirus initially discovered in Africa that causes a disease similar to smallpox with less severe symptoms. Since May 2022, the virus is being transmitted from human to human at an increasing rate outside of Africa. Although monkeypox infection was endemic in Africa, it had sporadic surges in recent years.

In this study, the biomass of Phragmites australis was chemically modified using NaOH and subsequently citric acid to produce an effective adsorbent named SA-RPB. The absorbent was characterized using XRD, SEM, BET, and FT-IR methods. The study's findings indicated that the adsorbent existed mainly as cellulose crystals, contained micropores with an average diameter of 15.

The herbicide diuron is extensively used in the agriculture sector and is detected widely in the environment. Although several studies on the degradation of diuron by aerobic microorganisms have been reported, the degradation of diuron by anaerobic microorganisms has not been received much attention. Also, no pure culture that can degrade diuron under anaerobic conditions has yet been reported.

Introduction: Contemporary data on the epidemiology of acute myocardial infarction (AMI) in Vietnam are extremely limited.

Methods: We established population-based registries of residents from 2 provinces in a northern urban (Hai Phong), and a central rural (Thanh Hoa), province of Vietnam hospitalized with a validated first AMI in 2018. We described patient characteristics, in-hospital management and clinical complications, and estimated incidence rates of AMI in these two registries.

Background: Physical activity and exercise improve function, symptom control, and health-related quality of life (QoL) for many cancer survivors; however, the evidence is limited and inconsistent in lung cancer. We examined the relationship between leisure-time physical activity (LTPA) and health-related QoL in a national sample of US lung cancer survivors.

Methods: We conducted a cross-sectional study using the Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System.

Thiobencarb is a herbicide globally used in the agricultural sector, and its extensive application leads to severe environmental pollution. In this study, the thiobencarb supplementation caused a significant shift in the bacterial community in the sediment slurry. An analysis of the degradation metabolites of microorganisms from the sediment indicated that deschlorothiobencarb, S-4-chlorobenzyl ethylthiocarbamate, 4-chlorobenzyl mercaptan, 4-chlorobenzyl alcohol, 4-chlorobenzoic acid and chlorobenzene were the main intermediates.
