BACKGROUND: Increasing evidence has suggested a strong association of Q223R (rs1137101) and K109R (rs1137100) polymorphisms in leptin receptor (LEPR) gene with susceptibility of breast cancer (BC), but inconsistent results were obtained. To provide a quantitative assessment of this association, a systematic review and meta-analysis was performed. METHODS: A literature search of PubMed, EMBASE, Google Scholar and the Chinese Nationlal Knowledge Infrastructure was collected...

BACKGROUND: The etiology of autism spectrum disorder (ASD) includes oxidative stress and brain inflammation. We investigated the relationship among oxidative stress markers, in vivo inflammatory substances, and antioxidants that can be easily measured in the clinic and compared them between children with ASD and those with typical development (TD). METHODS: Sixty-one children with TD and 199 with untreated ASD were investigated. They were Japanese children aged 2-15 years and were divided into those aged <7 and ≥7 years...

BACKGROUND: Patients undergoing transcatheter aortic valve replacement surgery (TAVR) are typically older adults with multiple chronic diseases and therefore have a high surgical risk. The N-terminal of brain natriuretic peptide (BNP) and pro-BNP, referred to as NT-pro-BNP, is an easily measurable biomarker of heart failure. Studies on correlation between higher NT-pro-BNP levels and adverse prognoses after TAVR have yielded inconsistent results. Here, we investigated whether preoperative NT-pro-BNP levels are correlated with outcomes among older adults undergoing TAVR...

BACKGROUND: To investigate the characteristics and clinical correlates of transient visual disturbances (TVDs) in patients with migraine without aura (MO). Patients with MO frequently report TVDs, which differ from typical visual aura, but the clinical significance of these TVDs has not been determined. METHODS: Patients with MO who attended our headache clinics were enrolled. Structured questionnaires were used to acquire data on participants' headache profiles, disability, comorbidities, and lifetime suicidal ideation and suicide attempts...

BACKGROUND: Pneumatic tourniquet is widely used in lower limb surgery to provide a bloodless operating field. Previous studies on total knee arthroplasty (TKA) in which tourniquets have been applied during surgery have reported some vascular and soft tissue complications. Nevertheless, it is still not well known exactly how use of tourniquets contributes to hemodynamics of the lower limb and its clinical relevance following TKA. In this prospective study, we wished to determine whether tourniquet affects the hemodynamics and postoperative healing of the lower limb in the first few weeks and its clinical relevancies following TKA...

BACKGROUND: The management of urolithiasis in the kidney has been drastically changed in the era of endourology, mainly consisting of three surgical procedures: extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), and retrograde intrarenal surgery (RIRS). Since ESWL is usually less invasive via ambulatory clinic routes, this study aimed to examine the stone-free rate (SFR) between PCNL and RIRS. METHODS: We retrospectively reviewed patients who had renal stones and were treated with either PCNL or RIRS from June 2016 to June 2018...

BACKGROUND: Chronic exposure to nicotine may change pain perception and promote opioid intake. This study aimed to evaluate the putative effect of cigarette smoking on opioid requirements and pain intensity after surgery. METHODS: Patients who underwent major surgery and received intravenous patient-controlled analgesia (IV-PCA) at a medical center between January 2020 and March 2022 were enrolled. Patients' preoperative smoking status was assessed using a questionnaire by certified nurse anesthetists...

BACKGROUND: This present study investigated the incidence rates of cardiotoxicity among cancer patients treated with immune checkpoint inhibitors (ICIs) plus other anticancer drugs. CONCLUSION: The incidence rate of ICI-related cardiotoxicity is low. Combination of ICI with either chemotherapy or targeted therapy might not significantly increase the risk of cardiotoxicities among cancer patients. Nevertheless, it is recommend being careful in patients treated high-risk cardiotoxicity medications to avoid drug-related cardiotoxicity with a combination of ICI therapy...

BACKGROUND: Both inflammation and oxidative stress contribute to the pathogenesis of sepsis and its associated organ damage. Angiotensin-(1-7), acting through the Mas receptor and angiotensin II-type 2 receptors (AT2R), could attenuate organ dysfunction and improve survival in rats with sepsis. However, the role of AT2R in inflammation and oxidative stress in rats with sepsis is unclear. Therefore, this study examined the modulatory effects and molecular mechanism of AT2R stimulation in rats with polymicrobial sepsis...

BACKGROUND: This study aimed to evaluate the anatomic and clinical outcomes of robot-assisted sacrohysteropexy (RASH) against robot-assisted sacrocolpopexy (RASC) for the treatment of primary advanced apical prolapse. METHODS: We conducted a retrospective cohort study of all robot-assisted pelvic organ prolapse surgeries for primary advanced apical prolapse (stage ≥II) between January 2011 and May 2021 at an academic tertiary hospital. Surgical outcomes and pelvic organ function were evaluated using the Pelvic Organ Prolapse Quantitative (POP-Q) stage and validated questionnaires (POPDI-6) during preoperative and postoperative 12-month follow-up evaluations...

BACKGROUND: Exoscope has been used in otoneurologic surgery in several reports. However, most ear surgeries are performed using either microscope or endoscopy today. The purpose of this study is to present our subjective and objective experience of using this instrument in our institution. METHODS: 16 ears with different severity and condition in 15 consecutive patients were enrolled. A questionnaire with 12 questions was sent to different participants, including surgeons, residents, medical students, and scrub nurses in the operation room...

BACKGROUND: To evaluate the clinical feasibility of interstitial brachytherapy by intraoperative free-hand catheter implantation in the treatment of early breast cancer after breast-conserving surgery. METHODS: Between January 2018 and December 2019, 44 patients with early breast cancer after breast-conserving surgery (BCS) who met the inclusion criteria ≥ 45 years old, invasive carcinoma ≤ 3cm or ductal carcinoma in situ (DCIS) <2.5cm, estrogen receptor (ER) positive, lymph node negative, surgical margin negative, no distant metastasis, and an ECOG performance score ≤ 1 were enrolled in this phase II single arm study...

BACKGROUND: Circulating tumor cells (CTCs) have been investigated as potential biomarker for predicting prognosis and monitoring therapeutic responses in colorectal cancer. However, the sensitivity of CTCs detection is low, thus limiting clinical utility of CTCs. We aim to examine the clinicopathological parameters that improve prognosis prediction for colorectal cancer using CTCs as a biomarker. METHODS: We enumerated CTCs in 186 CRC patients and associated the number of CTCs with the clinicopathological features and overall survival using univaritate and multivariate Cox regression model and Kaplan-Meier survival analysis...

BACKGROUND: Propafenone is a class IC antiarrhythmic agent that is commonly used as the first-line therapy for patients with paroxysmal atrial fibrillation (AF) in Taiwan. This study compared the efficacy and safety of generic (Rhynorm) and brand name (Rytmonorm) propafenone for rhythm control of paroxysmal AF in Taiwan. METHODS: This was an open-label randomized multicenter noninferior study conducted in Taiwan. We enrolled 76 patients with AF. To investigate the efficacy of propafenone, we used a wearable ECG event recorder to evaluate the daily burden of AF episodes in patients for 24 weeks...

Lead poisoning can damage human bodies silently, without specific symptoms or conspicuous warning signs. To provide safe and user-friendly tools for detecting heavy metals at low concentrations, scientists have developed and optimized versatile biosensors. To practically employ the developed biosensors specific for lead (e.g., the optimized Met-lead 1.44 M1), smartphone applications designed for user convenience and are easily operable for the on-site detection of Pb in environmental water, drinking water, food, and blood/urine, are urgently needed...
