Decoding Chirality Transfer Strengths and Structure-Property Relationships in Bismuth-Containing Chiral Hybrid Organic-Inorganic Semiconductors.

Chiral hybrid organic-inorganic semiconductors (CHOIS), which integrate chiral organic cations by hydrogen-bonding interactions with anionic metal halide subunits, have recently emerged as cutting-edge materials with the potential to revolutionize energy-efficient information processing, particularly in the realms of spintronics. By harnessing the inherent chirality of organic cations, CHOIS can effectively manipulate spin dynamics, a crucial factor for enhancing the device performance in next-generation electronics. However, the challenge lies in the limited understanding of structure-property relationships, which hinders the ability to control and fine-tune the chirality within these materials.

High-Speed and Hysteresis-Free Near-Infrared Optical Hydrogen Sensor Based on Ti/Pd Bilayer Thin Films.

Palladium (Pd) and titanium (Ti) exhibit opposite dielectric responses upon hydrogenation, with stronger effects observed in the near-infrared (NIR) region. Leveraging this contrast, we investigated Ti/Pd bilayer thin films as a platform for NIR hydrogen sensing-particularly at telecommunication-relevant wavelengths, where such devices have remained largely unexplored. Ti/Pd bilayers coated with Teflon AF (TAF) and fabricated via sequential electron-beam and thermal evaporation were characterized using optical transmission measurements under repeated hydrogenation cycles.

Radiofrequency ablation (RFA) plays a crucial role in the treatment of benign thyroid nodules by offering a minimally invasive alternative to surgical interventions. Nodule rupture is an uncommon complication of RFA. We present a case of nodule rupture and hyperthyroidism after RFA 41 days in a 45-year-old male patient.

Radiofrequency Ablation for Recurrent Papillary Thyroid Carcinoma at the Central Compartment Node: A Case Report.

Papillary thyroid carcinoma is the most common thyroid cancer with a good prognosis. However, local recurrence or cervical lymph node metastasis is frequent. Reoperation is a standard treatment but may be challenging due to the formation of fibrosis, cervical anatomy distortion, and the small size of recurrent lesions.

Within-household SARS-CoV-2 transmission and vaccine effectiveness in the first three COVID-19 school outbreaks in northern Viet Nam, September-December 2021.

Objective: The risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from schoolchildren to their household and the protective effects of vaccination in these settings remain poorly understood. We assessed the transmission dynamics of schoolchildren with SARS-CoV-2 within their households and the protective effects of coronavirus disease (COVID-19) vaccination among household members in Viet Nam.

Methods: We estimated the attack rate, vaccine effectiveness and adjusted risk ratio (aRR) of factors associated with SARS-CoV-2 transmission to household contacts of children confirmed to have COVID-19 who attended three schools in Ha Nam, Phu Tho and Thanh Hoa provinces between September and December 2021 using multivariable regression with household-level random effects.

Retinomorphic Color Perception Based on Opponent Process Enabled by Perovskite Bipolar Photodetectors.

The ability to perceive color by the retina can be attributed to both its trichromatic photoreceptors and the antagonistic neural wiring known as the opponent process. While neuromorphic sensors have been shown to demonstrate memory and adaptation capabilities, color perception is still challenging due to the intrinsic lack of spectral selectivity in narrow bandgap semiconductors. Furthermore, research on emulating neural wiring is severely lacking.

Hyperparathyroidism with acute pancreatitis in elderly patient treated by radiofrequency ablation: A case report.

Acute pancreatitis as an initial manifestation of primary hyperparathyroidism (PHPT) has been rarely reported. We report a case of acute pancreatitis from a hyperfunctioning parathyroid tumor in an 87-year-old woman with drowsy state. Laboratory tests showed high lipase, calcium, and intact parathyroid hormone level, and abdominal computed tomography scan revealed acute pancreatitis.

Integrating data analytics, peer support, and whole health coaching to improve the health outcomes of homeless veterans: Study protocol for an effectiveness-implementation trial.

Background: Homelessness is a strong determinant of acute care service utilization (inpatient hospitalization, emergency department visits) among US adults. Data analytics, peer support, and patient-centered approaches can collectively offer high-quality care for homeless patients who frequently utilize acute care ("super utilizers"). However, few outpatient programs have integrated these components and tested their effectiveness for this patient population.

Self-reported pain among Cambodian Americans with depression: patient-provider communication as an overlooked social determinant.

Objectives: Pain is common among torture survivors and refugees. Clear communication about one's pain is vital to timely and precise diagnosis and treatment but is rarely recognized as a social determinant of health. We examined whether self-reported difficulty communicating with their health care provider, along with standard social determinants, is associated with self-reported pain in Cambodian American refugees.

The objective of this study is to evaluate health-related quality of life (HRQoL) and activities of daily living (ADL) among postoperative surgery patients with complete cervical SCI in Vietnam and to explore the factors associated with these indices. A cross-sectional study was conducted on 88 adults in Vietnam from June 2018 to June 2019.

Burden of Influenza-Associated Respiratory Hospitalizations, Vietnam, 2014-2016.

Influenza burden estimates are essential to informing prevention and control policies. To complement recent influenza vaccine production capacity in Vietnam, we used acute respiratory infection (ARI) hospitalization data, severe acute respiratory infection (SARI) surveillance data, and provincial population data from 4 provinces representing Vietnam's major regions during 2014-2016 to calculate provincial and national influenza-associated ARI and SARI hospitalization rates. We determined the proportion of ARI admissions meeting the World Health Organization SARI case definition through medical record review.

The acceptability and feasibility of screening, brief intervention, and referral to treatment for pain management among new England veterans with chronic pain: A pilot study.

Objectives: Musculoskeletal disorders often lead to chronic pain in Veterans. Chronic pain puts sufferers at risk for substance misuse, and early intervention is needed for both conditions. This pilot study tested the feasibility and acceptability of a Screening, Brief Intervention, and Referral to Treatment for Pain Management intervention (SBIRT-PM) to help engage Veterans seeking disability compensation for painful musculoskeletal disorders in multimodal pain treatment and to reduce risky substance use, when indicated.

Screening, Brief Intervention, and Referral to Treatment for Pain Management for Veterans Seeking Service-Connection Payments for Musculoskeletal Disorders: SBIRT-PM Study Protocol.

Background: Veterans with significant chronic pain from musculoskeletal disorders are at risk of substance misuse. Veterans whose condition is the result of military service may be eligible for a disability pension. Department of Veterans Affairs compensation examinations, which determine the degree of disability and whether it was connected to military service, represent an opportunity to engage Veterans in pain management and substance use treatments.

Screening for Gambling Disorder in VA Primary Care Behavioral Health: A Pilot Study.
