Equestrian-Related Musculoskeletal Injuries Presenting to a Chiropractic Practice: A Retrospective Chart Review of 19 Patients.

Objective: The purpose of this study was to describe the types of equestrian-related musculoskeletal injuries and their management. Methods: We retrospectively reviewed the charts of 19 patients who presented with injuries from equestrian activities at a chiropractic practice from December 2000 to December 2020. Deidentified data were extracted from the charts and summarized. Results: Of the 19 patients, 42.3% presented with acute trauma, 38.5% had overuse injuries, and 19.2% had chronic injuries as a result of previous trauma. We found that 90% of overuse injuries and 18.2% of acute injuries led to chronic conditions that needed ongoing management. Conclusion: From this sample of patients, there was a high percentage of overuse and chronic injuries for patients who participated in equestrian activities.

The psychometric properties of the Vietnamese Version of the Five Facet Mindfulness Questionnaire.

BACKGROUND: Although recent decades have witnessed a growing interest in mindfulness with the development of many mindfulness scales and their adaptation to different cultures, there has been no attempt at developing or adapting a mindfulness scale for Vietnamese people. To fill this gap and encourage the study of mindfulness in Vietnam, we adapted a 20-item short-form of the Five Facet Mindfulness Questionnaire (FFMQ-20) into Vietnamese, which we called the FFMQ-V, and examined its psychometric properties in a series of three independent studies. METHODS: In Study 1, using a college sample (N = 412) we conducted several exploratory factor analyses to elucidate the factor structure of the FFMQ-V. In Study 2, using an independent college sample (N = 344) we performed a confirmatory factor analysis (CFA) to test the goodness-of-fit for all obtained factor models from Study 1. In this study, we also examined the discriminant validities of the FFMQ-V by correlating mindfulness and other related psychological constructs, including acceptance, nonattachment, depression, anxiety, and stress. In Study 3, we replicated all data analyses in Study 2 using a community sample of young adults (N = 574). RESULTS: Across all Studies, our results indicated that the hierarchical five-factor model with method factors best captured the latent structure of the FFMQ-V. Our results also showed that the mindfulness facets met our expectations as they correlated positively with the acceptance and nonattachment and negatively with the depression, anxiety, and stress. CONCLUSIONS: In aggregate, our EFA and CFA results provided strong evidence for the hierarchical five-factor model with method factors in both community and college samples, suggesting that the FFMQ-V can be used to measure trait mindfulness of the Vietnamese young adults.

Semisynthesis and biological evaluation of a focused library of unguinol derivatives as next-generation antibiotics.

In this study, we report the semisynthesis and in vitro biological evaluation of thirty-four derivatives of the fungal depsidone antibiotic, unguinol. Initially, the semisynthetic modifications were focused on the two free hydroxy groups (3-OH and 8-OH), the three free aromatic positions (C-2, C-4 and C-7), the butenyl side chain and the depsidone ester linkage. Fifteen first-generation unguinol analogues were synthesised and screened against a panel of bacteria, fungi and mammalian cells to formulate a basic structure activity relationship (SAR) for the unguinol pharmacophore. Based on the SAR studies, we synthesised a further nineteen second-generation analogues, specifically aimed at improving the antibacterial potency of the pharmacophore. In vitro antibacterial activity testing of these compounds revealed that 3-O-(2-fluorobenzyl)unguinol and 3-O-(2,4-difluorobenzyl)unguinol showed potent activity against both methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MIC 0.25-1 µg mL-1) and are promising candidates for further development in vivo.

Provider Perspectives on Integration of Substance Use Disorder and HIV Care in Vietnam: A Qualitative Study.

UNAIDS recommends integration of medications for substance use disorders (SUD) with HIV care to improve HIV outcomes. Yet, integration of HIV and SUD services remains limited in many countries. The objective of this study was to assess provider perceptions of care integration in Vietnam. Qualitative interviews were conducted with 43 providers (nurses, physicians, counselors, pharmacists, and clinic managers) in 8 HIV clinics in northern Vietnam, 2013-2015. Providers identified five themes informing HIV and SUD treatment integration: (1) treatment for alcohol use disorder is often neglected compared to other SUD treatment; (2) structural challenges must be addressed to increase integration feasibility; (3) workforce limitations; (4) societal and healthcare stigmatization of SUD; and (5) providers' conflicting views regarding integration challenges. The experience of providers in Vietnam may be useful to other countries attempting to integrate HIV and SUD services.

First rib fracture of unknown etiology: a case report.

OBJECTIVE: The purpose of this study is to describe the case of a patient with a first rib fracture discovered with advanced imaging once the patient did not respond to an initial course of care. CLINICAL FEATURES: A 24-year-old otherwise healthy male electrician had medial scapular, upper thoracic, and sternal pain while using a power drill in the overhead position. INTERVENTION AND OUTCOME: An initial trial of treatments consisting of spinal manipulation and modalities failed to alleviate the patient's symptoms. Chiropractic treatment was discontinued and further diagnostic testing with advanced imaging was performed. Once the pathology was identified, the patient was placed on light duty at work with restrictions limiting overhead activities. No other treatment was rendered. The patient was symptom-free approximately 10 months after the onset of pain. CONCLUSIONS: Patients with complaints of spine and scapular pain may commonly present to a chiropractor for care. When these types of symptoms do not respond to conservative therapy, other causes should be investigated. In this case, the patient's symptoms resulted from a nontraumatic fracture of the first rib. First rib fractures should be considered in the differential diagnosis of patients with upper quadrant pain that is not responsive to conservative care.

Preclinical pharmacokinetics and metabolism of 6-(4-(2,5-difluorophenyl)oxazol-5-yl)-3-isopropyl-[1,2,4]-triazolo[4,3-a]pyridine, a novel and selective p38alpha inhibitor: identification of an active metabolite in preclinical species and human liver microsomes.

The disposition of 6-(4-(2,5-difluorophenyl)oxazol-5-yl)-3-isopropyl-[1,2,4]-triazolo[4,3-a]pyridine (1), a potent and selective inhibitor of mitogen activated protein (MAP) kinase p38alpha, was characterized in several animal species in support of its selection for preclinical safety studies and potential clinical development. 1 demonstrated generally favorable pharmacokinetic properties in all species examined. Following intravenous (i.v.) administration, 1 exhibited low volumes of distribution at steady state (Vd(ss)) ranging from 0.4-1.3 l/kg (2.4-26 l/m(2)) in the rat, dog and monkey. Systemic plasma clearance was low in cynomolgus monkeys (6.00 ml/min/kg, 72.0 ml/min/m(2)) and Sprague-Dawley rats (7.65+/-1.08 ml/min/kg, 45.9+/-6.48 ml/min/m(2) in male rats and 3.15+/-0.27 ml/min/kg, 18.9+/-1.62 ml/min/m(2) in female rats) and moderate in beagle dogs (12.3+/-5.1 ml/min/kg, 246+/-102 ml/min/m(2)) resulting in plasma half-lives ranging from 1 to 5 h in preclinical species. Moderate to high bioavailability of 1 was observed in rats (30-65%), dogs (87%) and monkeys (40%) after oral (p.o.) dosing consistent with the in vitro absorption profile of 1 in the Caco-2 permeability assay. In rats, the oral pharmacokinetics were dose dependent over the dose range studied (5, 50 and 100 mg/kg). The principal route of clearance of 1 in rat, dog, monkey and human liver microsomes and in vivo in preclinical species involved oxidative metabolism mediated by cytochrome P450 enzymes. The major metabolic fate of 1 in preclinical species and humans involved hydroxylation on the isopropyl group to yield the tertiary alcohol metabolite 2. In human liver microsomes, this transformation was catalysed by CYP3A4 as judged from reaction phenotyping analysis using isozyme-specific inhibitors and recombinant CYP enzymes. Metabolite 2 was also shown to possess inhibitory potency against p38alpha in a variety of in vitro assays. 1 as well as the active metabolite 2 were moderately to highly bound to plasma proteins (f(u) approximately 0.1-0.33) in rat, mouse, dog, monkey and human. 1 as well as the active metabolite 2 did not exhibit competitive inhibition of the five major cytochrome P450 enzymes namely CYP1A2, 2C9, 2C19, 2D6 and 3A4 (IC(50)>50 microM). Overall, these results indicate that the absorption, distribution, metabolism and excretion (ADME) profile of 1 is relatively consistent across preclinical species and predict potentially favorable pharmacokinetic properties in humans, supporting its selection for toxicity/safety assessment studies and possible investigations in humans as an anti-inflammatory agent.
