The impact of the door-to-antivenom time on the resolution of coagulopathy caused by green pit viper bite-a retrospective cohort study.

Trimeresurus albolabris (green pit viper) accounts for 95% of human venomous snakebites in Hong Kong and the Green Pit Viper antivenin has become the only antivenom available. Little is known about the impact of early antivenom administration on the duration of venom-induced coagulopathy. This retrospective study aimed to evaluate the impact of the door-to-antivenom time (DTAT) on the duration of such coagulopathy.

Perioral Paresthesia, Generalize Muscle Cramps, and Rhabdomyolysis After a Socotra Island Blue Baboon Tarantula (Monocentropus Balfouri) Bite.

Background: Literature on systemic envenomation caused by tarantula bites, particularly from the Theraphosidae family, is relatively scarce. This case report provides a formal description of the first known instance of systemic envenomation caused by the Socotra Island Blue Baboon Tarantula (Monocentropus balfouri).

Case Report: In this case, a 23-year-old employee of an exotic pet shop suffered from perioral paresthesia, generalized muscle cramps, and rhabdomyolysis because of a Monocentropus balfouri bite.

Meaning in Life, Social Axioms, and Emotional Outcomes during the First Outbreak of COVID-19 in Hong Kong.

Social unrest, coupled with the outbreak of COVID-19, was a double-hit for Hong Kong in early 2020. Those stressful societal situations not only trigger negative emotions, such as anxiety and/or depression, but also consolidate a person's belief towards oneself (i.e.

Cholinergic Mushroom Poisoning With a Detection of Muscarine Toxin in Urine.

We report an uncommon case of cholinergic poisoning following an ingestion of wild mushrooms. Two middle-aged patients presented to the emergency unit with acute gastrointestinal symptoms including epigastric pain, vomiting and diarrhea, followed by miosis, palpitations and diaphoresis which were compatible with a cholinergic toxidrome. The patients volunteered a history of taking two tablespoons of cooked wild mushrooms collected in a country park.

Derivation and internal validation of a clinical prediction score to predict major effect or death in acute metamfetamine toxicity.

Objective: Metamfetamine use can cause serious complications or death. We aimed to derive and internally validate a clinical prediction score to predict major effect or death in acute metamfetamine toxicity.

Methods: We performed secondary analysis of 1,225 consecutive cases reported from all local public emergency departments to the Hong Kong Poison Information Centre between 1 January 2010 and 31 December 2019.

Awareness of meaning and quest for meaning: The mechanisms between future orientation and prosociality among youth during pandemic.

Introduction: The positive relationship between future orientation and prosocial tendency has been consistently reported. However, the possible mechanism has not been examined yet. Previous research revealed the positive relationship between future orientation and meaning in life, as well as between meaning in life and prosocial tendency.

Factors associated with seizure in tramadol overdose: a 12-year retrospective study in Hong Kong.

Background: Early identification of patients at risk of seizure after acute tramadol overdose is crucial. Yet, current evidence has been inconclusive regarding the factors associated with the seizure. There is a lack of study on the Chinese population and the value of electrocardiogram (ECG) in risk prognostication has not been fully evaluated.

Establishment and characterization of new tumor xenografts and cancer cell lines from EBV-positive nasopharyngeal carcinoma.

The lack of representative nasopharyngeal carcinoma (NPC) models has seriously hampered research on EBV carcinogenesis and preclinical studies in NPC. Here we report the successful growth of five NPC patient-derived xenografts (PDXs) from fifty-eight attempts of transplantation of NPC specimens into NOD/SCID mice. The take rates for primary and recurrent NPC are 4.

Will Victims Become Aggressors or Vice Versa? A Cross-Lagged Analysis of School Aggression.

Peer aggression and victimization are ubiquitous phenomena in schools which warrant the attention of educators and researchers. The high connection between aggression and victimization behooves researchers to look into how the comorbidity of them develops over time. The present study investigated the associations between aggression and victimization over 3 years in early adolescence and whether these associations are moderated by gender and teacher support.

Predictors for compliance of standard precautions among nursing students.

Background: We aimed to investigate the frequency of standard precautions (SPs) compliance and the factors affecting the compliance among nursing students (NSs).

Methods: A cross-sectional survey study guided by the health belief model was conducted in 2009. The study questionnaire is valid (content validity index, 0.

Development and validation of a Clostridium difficile risk assessment tool.

The incidence of Clostridium difficile infection has increased rapidly during the past decade, increasing lengths of stays in the hospital, costs, and mortality rates. To address this increased incidence, we performed a retrospective case-control study using known risk factors to develop a tool to determine which patients are at risk for infection. Multivariate analysis generated a combination of risk factors associated with development of infection including prior admission, endoscopy within 30 days, cephalosporin/fluoroquinolone use, length of stay 7 days or longer, age 65 years or older, body mass index less than 25, and albumin level less than 2.

A latent class growth analysis of school bullying and its social context: the self-determination theory perspective.

The contribution of social context to school bullying was examined from the self-determination theory perspective in this longitudinal study of 536 adolescents from 3 secondary schools in Hong Kong. Latent class growth analysis of the student-reported data at 5 time points from grade 7 to grade 9 identified 4 groups of students: bullies (9.8%), victims (3.

Intrinsic fluctuations of cell migration under different cellular densities.

The motility of the Dictyostelium discoideum (DD) cell is studied by video microscopy when the cells are plated on top of an agar plate at different densities, n. It is found that the fluctuating kinetics of the cells can be divided into two normal directions: the cell's forward-moving direction and its normal direction. Along the forward-moving direction, the slope of the amplitude of fluctuation vs.

Academic achievement trajectories of homeless and highly mobile students: resilience in the context of chronic and acute risk.

Analyses examined academic achievement data across third through eighth grades (N = 26,474), comparing students identified as homeless or highly mobile (HHM) with other students in the federal free meal program (FM), reduced price meals (RM), or neither (General). Achievement was lower as a function of rising risk status (General > RM > FM > HHM). Achievement gaps appeared stable or widened between HHM students and lower risk groups.

Dextrose 50% as a better substitute for saturated salt solution in mothball float test.

We describe the use of dextrose 50% solution to differentiate naphthalene and paradichlorobenzene in the mothball float test. Its advantages over saturated salt solution are discussed.

Academic achievement of homeless and highly mobile children in an urban school district: longitudinal evidence on risk, growth, and resilience.

Longitudinal growth trajectories of reading and math achievement were studied in four primary school grade cohorts (GCs) of a large urban district to examine academic risk and resilience in homeless and highly mobile (H/HM) students. Initial achievement was assessed when student cohorts were in the second, third, fourth, and fifth grades, and again 12 and 18 months later. Achievement trajectories of H/HM students were compared to low-income but nonmobile students and all other tested students in the district, controlling for four well-established covariates of achievement: sex, ethnicity, attendance, and English language skills.

Electronic excited states of [Au(2)(dmpm)(3)](ClO(4))(2) (dmpm= bis(dimethylphosphine)methane).

We present studies of the resonance Raman and electronic luminescence spectra of the [Au(2)(dmpm)(3)](ClO(4))(2) (dmpm = bis(dimethylphosphine)methane) complex, including excitation into an intense band at 256 nm and into a weaker absorption system centered about approximately 300 nm. The resonance Raman spectra confirm the assignment of the 256 nm absorption band to a (1)(dsigma --> psigma) transition, a metal-metal-localized transition, in that nu(Au-Au) and overtones of it are strongly enhanced. A resonance Raman intensity analysis of the spectra associated with the 256 nm absorption band gives the ground-state and excited-state nu(Au-Au) stretching frequencies to be 79 and 165 cm(-1), respectively, and the excited-state Au-Au distance is calculated to decrease by about 0.
