Compact Vital-Sensing Band with Uninterrupted Power Supply for Core Body Temperature and Pulse Rate Monitoring.

Although wearable devices for continuous monitoring of vital signs have undergone significant advancements, their need for frequent recharging precludes continuous operation, potentially leading to adverse outcomes being overlooked. Additionally, the scattered locations of the sensors hamper wearability. Herein, we present a compact vital-sensing band with uninterrupted power supply designed for continuous monitoring of core body temperature (CBT) and pulse rate.

Long-term weight patterns and physical activity in gallstones.

While obesity, rapid weight loss, and sedentary lifestyles contribute to gallstones, the impacts of long-term weight patterns and physical activity on gallstone risk have not been extensively studied at the population level. Using Korea's population-based health database, we created a cohort of 5,062,154 subjects who received over five consecutive biannual health check-ups from 2002 to 2018. Gallstone risk was calculated using hazard ratios (HRs) based on weight patterns (gain, loss, and cycling) and physical activity.

Incidence and risk of pancreatic cancer in patients with acute or chronic pancreatitis: a population-based cohort study.

We aimed to evaluate the incidence and risk of pancreatic cancer (PC) in pancreatitis. We identified patients with acute pancreatitis (AP) (n = 225,811, 50.0%) and chronic pancreatitis (CP) (n = 225,685, 50.

The Association of Body Mass Index and Waist Circumference with the Risk of Achilles Tendon Problems: A Nationwide Population-Based Longitudinal Cohort Study.

Background: The purpose of this study was to evaluate the association of body mass index (BMI) and waist circumference (WC) with the risk of Achilles tendinopathy (AT) or Achilles tendon rupture (ATR), using data from a nationwide population-based cohort. We hypothesized that higher BMI and WC would be independently associated with the increased risk of AT or ATR. In addition, a higher WC may potentiate the association between BMI and the risk of Achilles tendon problems.

Cholecystectomy reduces the risk of myocardial and cerebral infarction in patients with gallstone-related infection.

We compared the risk of myocardial infarction (MI) or cerebral infarction (CI) in patients with or without-gallstone-related infection (GSI) and change in the risk following cholecystectomy. GSI (n = 84,467) and non-GSI (n = 406,800) patients with age- and sex-matched controls (n = 4,912,670) were identified from Korean population based data. The adjusted hazard ratios (aHRs) of MI or CI were analyzed in both groups treated with or without cholecystectomy.

Cholecystectomy reduces the risk of cholangiocarcinoma in patients with complicated gallstones, but has negligible effect on hepatocellular carcinoma.

Background And Aim: Gallstones have been reported to be positively associated with hepatobiliary cancers. However, risks of these cancers by cholecystectomy or in patients with complicated gallstones are controversial. We studied the effect of cholecystectomy on the risk of cholangiocarcinoma (CCA) or hepatocellular carcinoma (HCC) in patients with gallstones and subgroup of complicated gallstones.

Dyslipidemia Is Associated With Increased Risk of Achilles Tendon Disorders in Underweight Individuals to a Greater Extent Than Obese Individuals: A Nationwide, Population-Based, Longitudinal Cohort Study.

Background: The association between dyslipidemia and Achilles tendinopathy (AT) or Achilles tendon rupture (ATR) remains controversial, although some studies have examined this topic.

Purpose: To evaluate the correlation of dyslipidemia and the risk of AT or ATR, and its association with body mass index (BMI), by assessing data from a nationwide population-based cohort.

Study Design: Cohort study; Level of evidence, 3.

Incidence, mortality, and cardiovascular diseases in pituitary adenoma in Korea: a nationwide population-based study.

Purpose: Few nationally representative studies have evaluated the epidemiology of PA (pituitary adenoma). This South Korean study evaluated the incidence of different PA subtypes, cardiovascular disease (CVD), and related mortality.

Methods: This population-based study evaluated 31,898 patients with PA during 2005-2015.

Anger-Related Characteristics According to Chronotypes in Bipolar or Depressive Disorders.

Objective: Though anger was highly associated with eveningness in general population, there is no study on the relationship between chronotype and anger-related characteristics in bipolar or depressive disorders. This study aimed to investigate the difference of anger-related characteristics according to chronotypes in bipolar or depressive disorders.

Methods: Patients with bipolar or depressive disorders (n=238) were included in this study.

Incidence, Long-Term Visual Outcomes, and Mortality in Retinopathy of Prematurity in Korea: A Nationwide Population-Based Study.

Purpose: To evaluate the incidence, visual prognosis, and mortality in retinopathy of prematurity (ROP) in Korea.

Methods: We used the National Health Insurance and the Korean Disability Registry database, which covers the entire newborn population in 2006 to 2014 and includes information on all newborns diagnosed with ROP until 2016. Using these databases, we evaluated the incidence, rate of visual impairment (VI), and mortality in patients with ROP according to the birth weight categories and treatment modalities.

Similarities and Differences of Strategies between Bipolar and Depressive Disorders on Stress Coping.

Objective: As coping strategies can influence the illness course of mood disorder, they could be potential targets for psychological intervention. The current study investigated the similarities and differences in stress coping styles between bipolar disorder (BD) and depressive disorder (DD).

Methods: Subjects with BD (n=135) and DD (n=100) who met the DSM-IV diagnostic criteria were included in this analysis.

Which growth parameters can affect mortality in cerebral palsy?

Background: The objective of this study was to identify growth parameters that can affect mortality of cerebral palsy (CP).

Method: This was a birth cohort study based on the National Health Screening Program for Infants and Children database along with the National Health Insurance Service, which were linked using a personal identifier number. The birth cohort consisted of 2 191 956 subjects, representing 93.

Incidence and Mortality Rates of Second Pancreatic Cancer Among Survivors of Digestive Cancers: A Nationwide Population-Based Study.

Objectives: We analyzed the incidence and mortality rates of second pancreatic ductal adenocarcinoma (PDAC) among survivors of digestive cancers in South Korea.

Methods: We evaluated data from the Korea National Health Insurance to identify individuals with digestive cancers in 2005 to 2015. The standardized incidence ratios (SIRs) of second PDACs and survival rates were evaluated.

Association of hyperuricemia and pulmonary hypertension: A systematic review and meta-analysis.

To investigate the association of hyperuricemia with pulmonary hypertension (PH) in term of subsequent development, severity, and prognosis of PH. The authors systematically reviewed articles from databases and conducted meta-analyses as follows: (1) association of serum uric acid (UA) levels with the presence of PH; (2) association between serum UA levels and subsequent development of PH, in terms of odds ratio of the development of PH; and (3) association of serum UA levels with severity and prognosis of PH, in terms of pulmonary arterial pressure and hazard ratio of death. Twenty-six studies published between 1999 and 2017 were included.

Incidence and Prognosis of Subsequent Cholangiocarcinoma in Patients with Hepatic Resection for Bile Duct Stones.

Background And Aim: Cholangiocarcinoma (CCA) often develops after the hepatic resection for hepatolithiasis as well as indwelling it. We studied the incidence and prognosis of subsequent CCA in patients with hepatolithiasis in South Korea.

Methods: We identified individuals with diagnosed CCA at the time of or after surgery, during 2002-2016, from the Korean National Health Insurance.

Can Residual Symptoms During Inter-Episode Period after Partial Remission in Bipolar I Disorder Have Cyclic Patterns with Specific Frequencies?

This case report aimed to describe cyclic patterns of residual mood symptoms in partially remitted bipolar I patient. In a 24-year-old woman with bipolar I disorder, residual mood symptoms measured by self-rated daily mood chart for 18 months were analyzed using wavelet analysis. A 146-day periodicity was prominent for the first 100 days after discharge.
