Quality systems regulations

Aims: Vincristine (VCR), an antineoplastic drug, induces peripheral neuropathy characterized by nerve damage, limiting its use and reducing the quality of life of patients. VCR causes myenteric neuron damage, inhibits gastrointestinal motility, and results in constipation or paralytic ileus in patients. Oxytocin (OT) is an endogenous neuropeptide produced by the enteric nerve system, which regulates gastrointestinal motility and exerts neuroprotective effects. This study aimed to investigate whether OT can improve VCR-induced gastrointestinal dysmotility and evaluate the underlying mechanism...

Despite global recommendations that surveillance systems should capture malaria case data from both private and public sectors, the integration of private sector data into national systems remains a challenge for national malaria programs in high-burden settings. The WHO's Malaria Surveillance, Monitoring & Evaluation: A Reference Manual suggests eight general guidelines for conducting private sector surveillance. Practical operational guidance is needed to implement private sector surveillance and service delivery interventions...

OBJECTIVE: Fibromyalgia syndrome (FMs) is a chronic, musculoskeletal pain disorder characterized by sleep disturbances, fatigue, and cognitive dysfunction. Heart rate variability biofeedback (HRV-BF) aiming to improve self-regulation and strengthen the parasympathetic nervous system has been shown to be effective in several pain syndromes, but its efficacy in FMs has not been adequately investigated. This Phase II trial aimed to assess the feasibility and preliminary measurement of the improvement induced by HRV-BF in FMs...

Patient reported outcomes (PROs) are measures of patients' health that are conveyed directly by individual patients. These measures serve as instruments to evaluate the impact of interventions on any aspect of patients' health, from specific symptoms to broader quality-of-life indicators. However, their effectiveness relies on capturing relevant factors accurately. While commonly utilized in clinical trials, PROs extend their influence across healthcare settings, informing clinicians, healthcare payers, regulators, and administrators to guide quality improvement and reimbursement decisions...

GLP test facility management refers to the proper management and organization of a facility that conducts studies according to GLP regulations. Compliance with GLP regulations is necessary for data generated in such facilities to be accepted by regulatory authorities. According to GLP Principles, Test facility management (TFM) is responsible for a wide range of tasks and responsibilities to ensure the smooth and efficient operation of the facility. The framework in which the TFM operates within the Test Facility is certainly much more complex than in the early days of the GLP, and moreover it is unlikely that anything will change from a scientific and technological point of view in the years to come...

The aggregation of α-synuclein (αS) plays a key role in Parkinson's disease (PD) etiology. While the onset of PD is age-related, the cellular quality control system appears to regulate αS aggregation throughout most human life. Intriguingly, the protein 14-3-3τ has been demonstrated to delay αS aggregation and the onset of PD in various models. However, the molecular mechanisms behind this delay remain elusive. Our study confirms the delay in αS aggregation by 14-3-3τ, unveiling a concentration-dependent relation...

BACKGROUND: Professional licensing bodies are valuable sources for tracking the health workforce, as many skilled health-care providers require formal training, registration, and licensure. Regulatory activities in Ethiopia were not effectively implemented due to poor follow-up and gaps in skilled human resources, budget, and information technology infrastructure. OBJECTIVE: The aim of this study was to explore and describe the lived experiences and challenges faced by health care managers in health professionals' licensure practices in Ethiopia...

In the context of aging, the susceptibility to infectious diseases increases, leading to heightened morbidity and mortality. This phenomenon, termed immunosenescence, is characterized by dysregulation in the aging immune system, including abnormal alterations in lymphocyte composition, elevated basal inflammation, and the accumulation of senescent T cells. Such changes contribute to increased autoimmune diseases, enhanced infection severity, and reduced responsiveness to vaccines. Utilizing aging animal models becomes imperative for a comprehensive understanding of immunosenescence, given the complexity of aging as a physiological process in living organisms...

As for other mammals, the digestive system of dogs (facultative carnivores) and cats (obligate carnivores) includes the mouth, teeth, tongue, pharynx, esophagus, stomach, small intestine, large intestine, and accessory digestive organs (salivary glands, pancreas, liver, and gallbladder). These carnivores have a relatively shorter digestive tract but longer canine teeth, a tighter digitation of molars, and a greater stomach volume than omnivorous mammals such as humans and pigs. Both dogs and cats have no detectable or a very low activity of salivary α-amylase but dogs, unlike cats, possess a relatively high activity of pancreatic α-amylase...
