Comparative evaluation of radiographic morphologic parameters for predicting subsequent contralateral fragility hip fracture.

Purpose: Subsequent contralateral fragility hip fracture (SCHF) is one of the most serious conditions in osteoporotic patients due to high morbidity and mortality. This study aimed to investigate the predictive ability of radiographic morphologic parameters for SCHF in patients diagnosed with unilateral fragility hip fractures.

Methods: We conducted a retrospective observational study of unilateral fragility hip fracture patients between April 2016 and December 2021.

Microcystic Stromal Tumor with Predominant Bizarre Nuclei of Ovary in a Pregnant Woman.

Microcystic stromal tumor (MST) is a rare type of pure stromal tumor in the category of ovarian sex cord-stromal tumors. It is characterized by a distinctive microcystic appearance with bland tumor cells. Although the pathological diagnosis can be straightforward based on the typical histomorphology in most MSTs, the cases with morphologic variation can pose a diagnostic challenge due to unfamiliarity of pathologists with the histologic spectrum of MST and its negativity for inhibin and calretinin, the commonly used sex cord-stromal markers.

Genetic basis of sudden death after COVID-19 vaccination in Thailand.

Background: Severe acute respiratory syndrome coronavirus 2 vaccination reduces morbidity and mortality associated with coronavirus disease 2019 (COVID-19); unfortunately, it is associated with serious adverse events, including sudden unexplained death (SUD).

Objective: We aimed to study the genetic basis of SUD after COVID-19 vaccination in Thailand.

Methods: From April to December 2021, cases with natural but unexplained death within 7 days of COVID-19 vaccination were enrolled for whole exome sequencing.

Prevalence of High-Risk Human Papillomavirus Infections before and after Cervical Lesion Treatment, among Women Living with HIV.

Even when receiving combination antiretroviral therapy, women living with HIV are at high risk of human papillomavirus (HPV) infection and/or cervical lesions, including cancer. Using data from the PapilloV prospective cohort, we evaluated the prevalence of high-risk HPV (HR-HPV) infections after cervical lesion treatment and investigated factors associated with their carriage. Women were followed up for three years with annual Pap smear and HPV genotyping.

Platinum-based chemotherapy and bevacizumab instigate the destruction of human ovarian cancers via different signaling pathways.

The standard chemotherapy regimens of ovarian cancer are platinum-based chemotherapy (carboplatin and paclitaxel) and bevacizumab (BEV). However, the effects of BEV alone or combined with carboplatin and paclitaxel on mitochondrial dynamics, mitochondrial function, mitophagy, apoptosis, inflammation and vascular endothelial growth factor (VEGF) in human ovarian cancer mitochondria and cells have not yet been investigated. Therefore, we aimed to test the hypothesis that 1) platinum-based chemotherapy and BEV equally damage isolated mitochondria from human ovarian cancers, and ovarian cancer cells through inducing mitochondrial dynamics dysregulation, mitochondrial dysfunction, increased mitophagy and apoptosis, as well as altered inflammation and VEGF; and 2) combined therapies exert greater damage than monotherapy.

Scale Development and Validation to Measure Occupational Health Literacy Among Thai Informal Workers.

Background: The high incidence of work-related diseases and injuries among day-laborers and workers with no legal contracts (informal workers) has received the attention of the Thai authorities. Workers' low occupational health literacy (OHL) has been reasoned as one contributing factor. Absence of a valid tool has prevented assessment of informal workers' OHL.

Mitochondrial Fusion Promoter Alleviates Brain Damage in Rats with Cardiac Ischemia/Reperfusion Injury.

Background: Cardiac ischemia/reperfusion (I/R) injury induces brain damage through increased blood-brain barrier (BBB) breakdown, microglial hyperactivity, pro-inflammatory cytokines, amyloid-β deposition, loss of dendritic spines, brain mitochondrial dysfunction, and imbalanced mitochondrial dynamics. Previous studies demonstrated that mitochondrial fusion promoter reduced cardiac damage from cardiac I/R injury; however, following cardiac I/R injury, the roles of mitochondrial dynamics on the brain have not been investigated.

Objective: To investigate the effects of pharmacological modulation using mitochondrial fusion promoter (M1) in the brain of rats following cardiac I/R injury.

Deep learning versus human graders for classifying diabetic retinopathy severity in a nationwide screening program.

Deep learning algorithms have been used to detect diabetic retinopathy (DR) with specialist-level accuracy. This study aims to validate one such algorithm on a large-scale clinical population, and compare the algorithm performance with that of human graders. A total of 25,326 gradable retinal images of patients with diabetes from the community-based, nationwide screening program of DR in Thailand were analyzed for DR severity and referable diabetic macular edema (DME).

Possible Roles of Mitochondrial Dynamics and the Effects of Pharmacological Interventions in Chemoresistant Ovarian Cancer.

Ovarian cancer is the major cause of death out of all the gynecologic cancers. The prognosis of this cancer is quite poor since patients only seek treatment when it is at an advanced stage. Any early biomarkers for this cancer are still unknown.

Role of microglia under cardiac and cerebral ischemia/reperfusion (I/R) injury.

Both cerebral and cardiac ischemia causes loss of cerebral blood flow, which may lead to neuronal cell damage, neurocognitive impairment, learning and memory difficulties, neurological deficits, and brain death. Although reperfusion is required immediately to restore the blood supply to the brain, it could lead to several detrimental effects on the brain. Several studies demonstrate that microglia activity increases following cerebral and cardiac ischemic/reperfusion (I/R) injury.

Tenofovir versus Placebo to Prevent Perinatal Transmission of Hepatitis B.

Background: Pregnant women with an elevated viral load of hepatitis B virus (HBV) have a risk of transmitting infection to their infants, despite the infants' receiving hepatitis B immune globulin.

Methods: In this multicenter, double-blind clinical trial performed in Thailand, we randomly assigned hepatitis B e antigen (HBeAg)-positive pregnant women with an alanine aminotransferase level of 60 IU or less per liter to receive tenofovir disoproxil fumarate (TDF) or placebo from 28 weeks of gestation to 2 months post partum. Infants received hepatitis B immune globulin at birth and hepatitis B vaccine at birth and at 1, 2, 4, and 6 months.

Thus, the main objective of this study was to compare the appropriateness of prescribing carbapenem before and after using an antimicrobial restriction system without infectious diseases consultation.

Materials And Methods: A retrospective cross-sectional before and after study was conducted in Lamphun Hospital to limit the prescription of carbapenems.

Brief Report: AIDS-Defining Events and Deaths in HIV-Infected Children and Adolescents on Antiretrovirals: A 14-Year Study in Thailand.

Background: Data are scarce on the long-term clinical outcomes of perinatally HIV-infected children and adolescents receiving antiretroviral therapy (ART) in low/middle-income countries. We assessed the incidence of mortality before (early) and after (late) 6 months of ART and of the composite outcome of new/recurrent AIDS-defining event or death >6 months after ART start (late AIDS/death) and their associated factors.

Methods: Study population was perinatally HIV-infected children (≤18 years) initiating ART within the Program for HIV Prevention and Treatment observational cohort (NCT00433030).

Human Papillomavirus infection and cervical lesions in HIV infected women on antiretroviral treatment in Thailand.

Objectives: To estimate the prevalence and factors associated with Human Papillomavirus (HPV) infection, HPV genotypes and cytological/histological high-grade (HSIL+/CIN2+) lesions.

Methods: We conducted a cross-sectional study within a prospective cohort of HIV-infected women on combination antiretroviral therapy (cART). Cervical specimens were collected for cytology and HPV genotyping (Papillocheck).

Hematological and Molecular Characterization of Hb J-Buda [α61(E10)Lys → Asn, AAG > AAT].

Hemoglobin (Hb) J-Buda [α61(E10)Lys → Asn, AAG > AAT] is a very rare α-chain variant found in South-East Asia. We analyzed hematological parameters and provided a rapid molecular analysis method for detection of this hemoglobinopathy in two Thai women who had severe microcytic anemia with Hb and MCV <70 g/L and 80 fL, respectively. The HPLC revealed an abnormal Hb peak eluted ahead of HbA at retention time of 1.

Purpose: This study evaluated and compared interradicular distances and cortical bone thickness in Thai patients with Class I and Class II skeletal patterns, using cone-beam computed tomography (CBCT).

Materials And Methods: Pretreatment CBCT images of 24 Thai orthodontic patients with Class I and Class II skeletal patterns were included in the study. Three measurements were chosen for investigation: the mesiodistal distance between the roots, the width of the buccolingual alveolar process, and buccal cortical bone thickness.

Underrecognized Peripheral Arterial Disease in Patients With Diabetes Mellitus in Thailand: We Must Consider Neuroischemic Foot Ulcers From This Fallout.

A range of prevalence of peripheral artery disease in diabetic patients has been estimated using the measurement of ankle brachial pressure index and clinical features in Asian countries. These data may be underestimates and hence underrecognized, raising questions about the numbers of patients with neuroischemic feet who are also at risk of diabetic foot ulcers. Underrecognition of these lesions may well increase the high levels of chronic wound burden resulting from peripheral artery disease as well as neuroischemic foot lesions.
