Military Service Roles and ALS Among Veterans: A Matched Case–Control Study
ABSTRACT While military service is an established risk factor for amyotrophic lateral sclerosis (ALS), it remains unclear whether this association is linked to combat. We conducted a matched case–control study comparing 191 ALS patients who were veterans of the Israeli Defense Forces (IDF) with known military service type and 1910 matched controls. The

An Overview on Estimation of Postmortem Interval
Throughout the history of forensic medicine, the postmortem interval (PMI) has been one of the commonly and thoroughly investigated problems. Despite many decades of research, accuracy in estimation of the time of death has not significantly improved and no single method can be reliably used to accurately estimate the time of death.

Phenotyping Healthcare Use 2–3 Decades Before the First Multiple Sclerosis Demyelinating Event
ABSTRACT Objective Phenotype hospital, physician, and emergency department (ED) visits by diagnoses and specialty up to 29 years pre‐multiple sclerosis (MS) onset versus a matched population without MS. Methods We identified people with MS (PwMS) using population‐based administrative data from Ontario, Canada (1991–2020).

Asymptotic optimality in sequential interval estimation [PDF]
Let \(X_ 1\), \(X_ 2,..\). be i.i.d. normal random variables with unknown mean \(\mu\) and unknown variance \(\sigma^ 2\). Let \(\bar X{}_ n\) and \(\bar S{}^ 2_ n\) denote the sample means and variances. For h \((>0)\) let \(I_ n=[\bar X_ n-h\), \(\bar X+h]\) be the confidence intervals with confidence coefficient being at least larger than a ...

Amyotrophic Lateral Sclerosis as a Multistep Process in the United States: A Population‐Based Study
ABSTRACT Background Amyotrophic lateral sclerosis (ALS) is a fatal, progressive neurodegenerative disease that typically results in death within 3–5 years from symptom onset. However, little is known about the environmental exposures, clinical aspects, or social determinants of health factors that may be associated with the disease.

Influence of Dystrophin Isoform Deficiency on Motor Development in Duchenne Muscular Dystrophy
ABSTRACT Objective In Duchenne muscular dystrophy (DMD), lack of the shorter dystrophin isoforms Dp140 and Dp71 is associated with increased central nervous system (CNS) involvement. We aimed to investigate how CNS involvement affects motor development in young DMD boys.

Improved reference-interval estimation.
Abstract We used two standard methods (the common percentile and the log-power gaussian transformation) and two novel methods (weighted percentile and smoothed spline interpolation) to estimate the 2.5th and 97.5th percentiles of 1000 sets of data from eight diverse distributional forms, generated by Monte Carlo simulation.
