Article Abstract
Malaysia is currently facing an outbreak of COVID-19. We aim to present the first study in Malaysia to report the reproduction numbers and develop a mathematical model forecasting COVID-19 transmission by including isolation, quarantine, and movement control measures. We utilized a susceptible, exposed, infectious, and recovered (SEIR) model by incorporating isolation, quarantine, and movement control order (MCO) taken in Malaysia. The simulations were fitted into the Malaysian COVID-19 active case numbers, allowing approximation of parameters consisting of probability of transmission per contact (), average number of contacts per day per case (), and proportion of close-contact traced per day (). The effective reproduction number (R) was also determined through this model. Our model calibration estimated that (), (), and () were 0.052, 25 persons, and 0.23, respectively. The (R) was estimated to be 1.68. MCO measures reduce the peak number of active COVID-19 cases by 99.1% and reduce () from 25 (pre-MCO) to 7 (during MCO). The flattening of the epidemic curve was also observed with the implementation of these control measures. We conclude that isolation, quarantine, and MCO measures are essential to break the transmission of COVID-19 in Malaysia.

Accurate determination of the parameters of each high purity germanium, HPGe detectors ensure the precision of quantitative results obtained from spectrum analysis. This study presents a comprehensive performance evaluation and long-term quality control assessment of a high-purity germanium (HPGe) gamma spectrometry system that has been operational for over 15 years. Key spectrometric measures were recorded, including energy resolution, peak shape ratios, asymmetry, peak-to-Compton ratio, relative efficiency, electronic noise, minimum detectable activity (MDA), and repeatability and reproducibility of the system.

Objective: We previously documented that exposure to a spectrum of elements is associated with autism spectrum disorder (ASD). However, there is a lack of mechanistic understanding as to how elemental mixtures contribute to the ASD development.
Materials And Methods: Serum and urinary concentrations of 26 elements and six biomarkers of ASD-relevant pathophysiologic pathways including serum HIPK 2, serum p53 protein, urine malondialdehyde (MDA), urine 8-OHdG, serum melatonin, and urine carnitine, were measured in 21 ASD cases and 21 age-matched healthy controls of children aged 6-12 years.
Strong Families Start at Home/Familias Fuertes Comienzan en Casa-Improving Child Diet Quality and Parental Feeding Practices: Protocol for a Randomized Controlled Trial.

Background: Children in the United States have poor diet quality, increasing their risk for chronic disease burden later in life. Caregivers' feeding behaviors are a critical factor in shaping lifelong dietary habits. The Strong Families Start at Home/Familias Fuertes Comienzan en Casa (SFSH) was a 6-month, home-based, pilot randomized-controlled feasibility trial that aimed to improve the diet quality of 2-5-year-old children and promote positive parental feeding practices among a predominantly Hispanic/Latine sample.

To examine how one's community connectedness may act as a source of resilience and promote HIV prevention and care behaviors among transgender women of color. We analyzed survey data from 313 transgender women of color living in New York City collected from August 2020 to November 2022. The Community Connectedness Scale asks participants about their baseline feelings of connection, feelings of inclusion, feelings of belonging, feelings of isolation, and feelings of being unlike in relation to the transgender community.

Rationale: There are insufficient data to inform the management of central sleep apnea (CSA) in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Nocturnal oxygen therapy (NOT) has been postulated to benefit CSA patients with HFrEF, but has not been rigorously studied.
