Applying interpretable machine learning in computational biology-pitfalls, recommendations and opportunities for new developments.

Recent advances in machine learning have enabled the development of next-generation predictive models for complex computational biology problems, thereby spurring the use of interpretable machine learning (IML) to unveil biological insights. However, guidelines for using IML in computational biology are generally underdeveloped. We provide an overview of IML methods and evaluation techniques and discuss common pitfalls encountered when applying IML methods to computational biology problems.

Joint association of aerobic physical activity and muscle-strengthening activities with metabolic syndrome : the Korean National Health and Nutrition Examination Survey 2014-2015.

Objectives: The study aimed to examine whether simultaneously meeting the combined guidelines of accelerometer-assessed moderate to vigorous physical activity (MVPA) and self-reported muscle-strengthening activity (MSA) was associated with lower odds of metabolic syndrome (MetS) than meeting neither or 1 of the guidelines among the Koreans.

Methods: This cross-sectional analysis included 1,355 participants from the Korea National Health and Nutrition Examination Survey (2014-2015). Logistic regression was used to analyze the associations across groups of MVPA-MSA guideline adherence (meeting neither [reference]; meeting MVPA only; meeting MSA only; meeting both MVPS and MSA) with MetS components (abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol [HDL-C], hypertension, and hyperglycemia).

Characteristic Magnetic Resonance Image Features of Acute Network Injury in Young Patients.

Cerebral infarction is known to cause secondary degeneration of the areas connected to the primarily damaged regions. This has been named as acute network injury and is usually recognized in newborns or babies by high signal intensity on diffusion-weighted imaging (DWI). In this article, we present 2 cases demonstrating several characteristics of network injury.

Accelerometer-measured stepping cadence patterns in Korean adults: an analysis of data from the 2014-2015 Korea National Health and Nutrition Examination Survey.

Objectives: The aim of this study was to identify the stepping cadence patterns in Korean adults by using objectively measured accelerometer data to analyze the time spent in each cadence category by sex and age.

Methods: During the 2014-2015 Korean National Health and Nutrition Examination Survey, 1,703 males and females aged 19-64 years provided at least 1 valid day of data (wearing an accelerometer ≥ 10 hr/d). The mean cumulative time and percentage per day in 8 cadence categories (0, 1-19, 20-29, 30-59, 60-79, 80-99, 100-119, and ≥ 120 steps/min) by sex and age group were calculated.

Relationship of Physical Activity and Sedentary Time with Metabolic Health in Children and Adolescents Measured by Accelerometer: A Narrative Review.

The purpose of this study was to summarize the associations of physical activity (PA) and sedentary time (SED) with metabolic health and examine the effects of time reallocation on metabolic health in adolescents using accelerometer data. A literature search was conducted using PubMed, ScienceDirect, Web of Science, Cochran Library, and Google Scholar, and 27 articles were reviewed. Recent research generally confirms the associations of PA and SED with metabolic health.

Fine-scale mapping of an evidence-based heat health risk index for high-density cities: Hong Kong as a case study.

The most recent extreme heat recorded in Europe re-alerts the world to the threat of heat stress. Future extreme heat events are reported to be more frequent, long-lasting, and intense. The intense exposure to hot temperatures can cause an excess of heat-related deaths, leading to an increasing risk of heat-related health.

Combined exercise improves gastrointestinal motility in psychiatric in patients.

Aim: To examine the effect of combined exercise on colonic transit time (CTT) in admitted psychiatric patients.

Methods: Over a 6-mo period, consecutive in patients with mental illness were recruited from the Somang Hospital Psychiatry Unit. A combined exercise program that included 60 min per day of exercise 3 d per week for 12 wk was performed.

Effect of acute intradialytic aerobic and resistance exercise on one-day blood pressure in patients undergoing hemodialysis: a pilot study.

Background: Hypertension and intradialytic hypotension are independent risk factors for mortality in hemodialysis patients. We hypothesized that intradialytic exercise would increase blood pressure (BP) during dialysis and decrease it during the postdialytic period. The present study aimed to investigate the effect of acute intradialytic exercise on BP both during dialysis and for 20 hours postdialysis, and to detect any differences in effects of aerobic exercise (AE), resistance exercise (RE), and usual care (UC-the control condition).

Purpose: The aim of this study was to evaluate the diagnostic accuracy of urinary biomarkers, such as neutrophil gelatinase-associated lipocalin (uNGAL) and β-2 microglobulin (uB2MG), in early detection of urinary tract infection (UTI) in infants aged <3 months with fever.

Methods: A total of 422 infants aged <3 months (male:female=267:155; mean age, 56.4 days), who were admitted for fever, were retrospectively included in this study.

A multicenter trial of oxcarbazepine oral suspension monotherapy in children newly diagnosed with partial seizures: a clinical and cognitive evaluation.

Purpose: We conducted a prospective, multicenter, open label trial to evaluate the effectiveness of oxcarbazepine (OXC) oral suspension as monotherapy for children newly diagnosed with partial seizures.

Methods: This trial included a two- to eight-week titration and stabilization period to achieve effective target doses and a 24-week maintenance phase. The primary outcome measure was the seizure-free rate over six months, while a secondary measure was the change in cognition and behavior from screening to the end of the maintenance phase.

B-type natriuretic Peptide assay for the diagnosis and prognosis of patent ductus arteriosus in preterm infants.

Background And Objectives: Patent ductus arteriosus (PDA) is a significant cause of morbidity and mortality in preterm infants. Measurement of plasma B-type natriuretic peptide (BNP) has been reported to be a useful bedside screening tool for the presence of hemodynamically significant PDA (hsPDA) in neonates. This study was conducted to investigate the usefulness of a BNP assay as a biochemical marker for the diagnosis of hsPDA and predictive biomarker of the response to indomethacin in preterm infants.

Excessive crying: behavioral and emotional regulation disorder in infancy.

In the pediatric literature, excessive crying has been reported solely in association with 3-month colic and is described, if at all, as unexplained crying and fussing during the first 3 months of life. The bouts of crying are generally thought to be triggered by abdominal colic (over-inflation of the still immature gastrointestinal tract), and treatment is prescribed accordingly. According to this line of reasoning, excessive crying is harmless and resolves by the end of the third month without long-term consequences.

Intermediate and long-term results of transcatheter closure of patent foramen ovale using the amplatzer patent foramen ovale occluder: one case of pulmonary embolism irrespective of patent foramen ovale closure.

Background And Objectives: Patent foramen ovale (PFO) has been implicated in the pathogenesis of cryptogenic stroke or transient ischemic attack (TIA) due to paradoxical embolism, and in the pathogenesis of migraine. This paper reports the intermediate and long-term results of transcatheter closure of PFO associated with cerebrovascular accidents (CVAs), TIAs and migraine, using the Amplatzer PFO occluder. This paper also reports a case of pulmonary embolism which developed in one patient after PFO closure.

The effect of ephedrine on intraoperative hypothermia.

Background: Prevention of intraoperative hypothermia has become a standard of operative care. Since ephedrine has a thermogenic effect and it is frequently used to treat hypotension during anesthesia, this study was designed to determine the effect of ephedrine on intraoperative hypothermia of patients who are undergoing spine surgery.

Methods: Twenty-four patients were randomly divided to receive an ephedrine (the ephedrine group, n = 12) or normal saline (the control group, n = 12) infusion for 2 h.

Comparative trial of low- and high-dose zonisamide as monotherapy for childhood epilepsy.

Purpose: To evaluate the effectiveness of zonisamide (ZNS) as monotherapy in children with newly diagnosed epilepsy.

Methods: This randomized, multicenter trial included a 2-4-week titration and a 24-week maintenance phase after randomization to low-(3-4 mg/kg/day) or high-(6-8 mg/kg/day) dose groups as target maintenance dosages. The primary outcome measure was the seizure-free rate over 6 months, while a secondary measure was the change in cognition and behavior from screening to the end of the maintenance phase.

Caudal analgesia reduces the sevoflurane requirement for LMA removal in anesthetized children.

Background: An anesthetic state can reduce adverse airway reaction during laryngeal mask airway (LMA) removal in children. However, the anesthetic state has risks of upper airway obstruction or delayed emergence; so possibly less anesthetic depth is advisable. Caudal analgesia reduces the requirement of anesthetic agents for sedation or anesthesia; it is expected to reduce the sevoflurane requirement for LMA removal.

Estimating lumbar epidural space depth in infants and children of Korea.

Background: Lumbar epidural block is now a popular technique for anesthesia and post operative analgesia. It may be helpful for prevention of complication during this procedure to know the depth from the skin to the lumbar epidural space before the procedure. This study was undertaken to evaluate the depth from the skin to the lumbar epidural space and to determine any potential relationship between a patient's data (age, weight, and height) and the measured depth in Korean children.

[A case of partial trisomy 15q25.3-qter].

A 15q25-qter partial trisomy characterized by pre or postnatal overgrowth, tall stature, macrocephaly and craniosynostosis has rarely been reported. The cause of overgrowth has been thought to be the triplication of the insulin-like growth factor 1 receptor (IGF1R) gene located on the 15q26.3.

Lateral segregation of anionic phospholipids in model membranes induced by cytochrome P450 2B1: bi-directional coupling between CYP2B1 and anionic phospholipid.

The lateral segregation of anionic phospholipids phosphatidic acid (PA), phosphatidylinositol (PI), and phosphatidylserine (PS) was detected after addition of cytochrome P450 2B1 (CYP2B1). The tendency of lipid clustering was highly dependent on the type of anionic phospholipids examined. PA was the most highly clustered while PI and PS clustered to a lesser degree.
