Core muscle activity during TRX suspension exercises with and without kinesiology taping in adults with chronic low back pain: Implications for rehabilitation

This study aimed to examine the effects of kinesiology taping (KT) and different TRX suspension workouts on the amplitude of electromyographic (EMG) activity in the core muscles among people with chronic low back pain (LBP). Each participant (total n=21) was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1) hamstring curl, (2) hip abduction in plank, (3) chest press, and (4) 45-degree row. Right transversus abdominis/internal oblique (TrAIO), rectus abdominis (RA), external oblique (EO), and superficial lumbar multifidus (LMF) activity was recorded with surface EMG and expressed as a percentage of the EMG amplitude recorded during a maximal voluntary isometric contraction of the respective muscles. Hip abduction in plank increased TrAIO, RA, and LMF EMG amplitude compared with other TRX positions (P0.05). Hip abduction in plank most effectively activated abdominal muscles, whereas the hamstring curl most effectively activated the paraspinal muscles. Applying KT conferred no immediate benefits in improving the core muscle activation during TRX training in adults with chronic LBP.published_or_final_versio

Homeobox b5(Hoxb5) regulates the expression of Forkhead box D3 gene (Foxd3) in neural crest

Patterning of neural crest (NC) for the formation of specific structures along the anterio-posterior (A-P) body axis is governed by a combinatorial action of Hox genes, which are expressed in the neuroepithelium at the time of NC induction. Hoxb5 was expressed in NC at both induction and migratory stages, and our previous data suggested that Hoxb5 played a role in the NC development. However, the underlying mechanisms by which Hoxb5 regulates the early NC development are largely unknown. Current study showed that both the human and mouse Foxd3 promoters were bound and trans-activated by Hoxb5 in NC-derived neuroblastoma cells. The binding of Hoxb5 to Foxd3 promoter in vivo was further confirmed in the brain and neural tube of mouse embryos. Moreover, Wnt1-Cre mediated perturbation of Hoxb5 signaling at the dorsal neural tube in mouse embryos resulted in Foxd3 down-regulation. In ovo, Foxd3 alleviated the apoptosis of neural cells induced by perturbed Hoxb5 signaling, and Hoxb5 induced ectopic Foxd3 expression in the chick neural tube. This study demonstrated that Hoxb5 (an A-P patterning gene) regulated the NC development by directly inducing Foxd3 (a NC specifier and survival gene).postprin

Plasma cholesterol levels and brain development in preterm newborns.

BackgroundTo assess whether postnatal plasma cholesterol levels are associated with microstructural and macrostructural regional brain development in preterm newborns.MethodsSixty preterm newborns (born 24-32 weeks gestational age) were assessed using MRI studies soon after birth and again at term-equivalent age. Blood samples were obtained within 7 days of each MRI scan to analyze for plasma cholesterol and lathosterol (a marker of endogenous cholesterol synthesis) levels. Outcomes were assessed at 3 years using the Bayley Scales of Infant Development, Third Edition.ResultsEarly plasma lathosterol levels were associated with increased axial and radial diffusivities and increased volume of the subcortical white matter. Early plasma cholesterol levels were associated with increased volume of the cerebellum. Early plasma lathosterol levels were associated with a 2-point decrease in motor scores at 3 years.ConclusionsHigher early endogenous cholesterol synthesis is associated with worse microstructural measures and larger volumes in the subcortical white matter that may signify regional edema and worse motor outcomes. Higher early cholesterol is associated with improved cerebellar volumes. Further work is needed to better understand how the balance of cholesterol supply and endogenous synthesis impacts preterm brain development, especially if these may be modifiable factors to improve outcomes

Prescribing trends and indications of antipsychotic medication in Hong Kong from 2004 to 2014: General and vulnerable patient groups

PURPOSE: Antipsychotic-prescribing patterns remain unclear in Asia. The aims of our study were to investigate prescribing trends of antipsychotic medication in the general population, children, and older patients by drug generation (first or second), the prescribing trend in pregnant women, the probable indication for antipsychotic prescription, and the prescribing trend by dosage form. METHODS: This descriptive study identified and included all patients prescribed with antipsychotic in Hong Kong from 2004 to 2014 using the Clinical Data Analysis and Report System. This study calculated and reported the prevalence of antipsychotic prescribing in patient groups of interest, the percentage with diagnoses of mental disorders were derived, and the prevalence of antipsychotic by dosage forms. RESULTS: The study included 10 109 206 prescriptions of any antipsychotics to 256 903 patients. Over the study period, the prevalence of antipsychotic prescribing increased from 1.06% to 1.54% in the general population, from 0.10% to 0.23% in children (3-17 years old), and from 2.61% to 3.26% in older patients (≥65 years old). The prevalence of second-generation antipsychotics increased, but the prevalence of first-generation antipsychotics did not. Prevalence of antipsychotic prescribing in prepregnancy, pregnancy, and postpartum timeframes varied from 0.18% to 0.38%. The percentage of incident prescriptions with a diagnosis of psychosis decreased from 54.1% to 47.5%. CONCLUSIONS: Antipsychotics have been increasingly prescribed in the general population, children, and older patients. There is an increase in second-generation antipsychotic prescribing. Over half of incident users had a recent diagnosis of a nonpsychotic mental disorder in 2014, suggesting that off-label prescribing of antipsychotics might be common.

Nutrition and management of glycemia in neonates with neonatal encephalopathy treated with hypothermia.

Adequate nutrition and glycemic homeostasis are increasingly recognized as potentially neuroprotective for the developing brain. In the context of hypoxia-ischemia, evidence is scarce regarding optimal nutritional support and administration route, as well as the short- and long-term consequences of such interventions. In this review, we summarize current knowledge on disturbances of brain metabolism of glucose and substrates by hypoxia-ischemia, and compound effects of these mechanisms on brain injury characterized by specific patterns on EEG and MRI. Risks and benefits of nutrition delivery via parenteral or enteral routes are examined. Nutrition could mitigate adverse neurodevelopmental outcomes, and the impact of nutritional strategies and specific nutritional interventions are reviewed. Limited literature highlights the need for further studies to understand the changes in energy metabolism during and after hypoxic-ischemic injury, to optimize nutritional regimens and glucose management, and to inform the neuroprotective role of nutrition

Population-based estimates of the burden of pneumonia hospitalizations in Hong Kong, 2011–2015

Up-to-date data on the burden of disease are important to identify patients with unmet needs and to optimize healthcare resources. We aimed to characterize the burden of pneumonia hospitalizations in Hong Kong and inform targeted healthcare policies for pneumonia control in the era of global aging. This was a population-based study using a territory-wide administrative electronic health record system that covers all public hospitals of Hong Kong. Patients admitted to public hospitals, from 2011 to 2015, with a diagnosis of pneumonia at discharge were identified based on the International Classification of Diseases-Ninth Revision-Clinical Modification Codes (480–486 and 487.0). Incidence, inpatient case-fatality, all-cause fatality, 28-day readmission, hospital length of stay, and healthcare costs were assessed for seven age strata. We identified 323,992 patients (median age 80 years, 44.4% female) with hospitalized pneumonia (organism unspecified 84.2%; bacterial pneumonia 12.3%; viral pneumonia 2.5%; others 1.0%). Annual incidence was 955.1 per 100,000 population, with a 10.6% decrease from 2011 to 2015. Case-fatality, all-cause fatality, and 28-days readmission risks were 13.8, 21.6, and 19.5%, respectively. The average hospital length of stay was 14.1 days with corresponding direct costs of $9348 USD per episode in the monetary value of 2015. Individuals aged ≥ 65 years accounted for over 75% of pneumonia-related hospitalizations, 90% of deaths, and the majority of healthcare costs. Hospitalized pneumonia represents a considerable health and economic burden in Hong Kong, especially in older adults. The study provides a population-level baseline estimate for further cost-effective evaluation of targeted strategies for pneumonia control
