There is some evidence for a decreasing age of menarche in many populations. This study examined the secular trend of age at menarche among Iranian women. Age at menarche based on recall information was recorded for 770 pairs of mother and daughters. Between 1930 and 1990 mean menarcheal age of this cohort of women decreased from 13.88 to 12.98 years (-0.15 years per decade) and mean height of ...

OBJECTIVE To determine severe sepsis (SS) incidence, hospital mortality, 1-year mortality, and costs associated with care in a sample of enrollees in a nationally representative individual practice association (IPA)-network managed care organization (MCO). METHODS This was a retrospective analysis of administrative claims data for commercial (not managed Medicare) members. We identified MCO m...

INTRODUCTION Children under five years of age are highly vulnerable to malaria infection and often face dire consequences such as severe malaria if they are not promptly and adequately treated with effective anti-malarial medications. We set out to evaluate malaria and associated co-morbidity among children admitted with febrile illness in Sekondi-Takoradi, Ghana. METHODOLOGY This retrospecti...

Background: There is limited data about the short-term stroke mortality rates for patients in treatment settings. Objectives: This study aimed to estimate the short-term stroke (in hospital, one month, one year) mortality rates in Iran through a systematic review and meta-analysis. Materials & Methods: We searched electronic databases, including three national (IranDoc, Megiran, SID) and f...

 Background & Objective:  Low birth weight is considered as one the causes of infant mortality across the world. Accordingly, paying attention to neonatal growth leads to mortality rate decrement and consequently prevents future physical and mental disabilities in this age group.  Materials & Methods:  This historic (retrospective) cohort study was conducted on 280 one-year-old male and female...

BACKGROUND Dialysis in elderly patients (>80-years-old) carries a poor prognosis, but little is known about the most effective vascular access method in this age group. An arteriovenous fistula (AVF) is both time-consuming and initially expensive, requiring surgical insertion. A central venous catheter (CVC) is initially a cheaper alternative, but carries a higher risk of infection. We examined...

The magnetization transfer ratio reflects the integrity of tissue structure, including myelination and axonal density. Mean magnetization transfer ratio fell in 18 untreated patients with multiple sclerosis both in normal appearing grey (-0.25 pu/year, p < 0.001) and white matter (-0.12 pu/year, p = 0.004). Conversely, mean magnetization transfer ratio was stable in 20 alemtuzumab-treated patie...

The age of 116 males of the yellow weasel, Musteh sibirica corema, was de termined by the cementum-layer of the canine tooth, and the characters of the baculum. Six age classes (from the yearling to the five-year age class) were distinguished by the dental annuli. The one-year age class involved many individuals, and was followed by the two-year age class and then the yearling one in the number...
