Acute alcohol intoxication across different age groups in 2014-2018: Prehospital care and biochemical correlates at a large University Hospital in southern Italy.

BACKGROUND: Risky alcohol consumption can occur from a young age and affects people of all age groups, sometimes requiring the intervention of the emergency medical services. OBJECTIVES: Determining the timing and characteristics of emergency calls (to the "118" emergency number) relating to subjects in all age groups, in which alcohol was a contributing factor, along with the biochemical correlates, in a great metropolitan area. On the basis of these, future interventions would target specific training for nurses and paramedics working in emergency medical services. METHOD: An observational single-centre retrospective study carried out from 1 January 2014 to 31 December 2018 involving patients requiring emergency care and attending the Emergency Department of an University Hospital. RESULTS: Out of a total of 47,252 emergency calls, 2.22% were for alcohol-related conditions and mainly involved male patients (78.4%). A high incidence of alcoholic coma was found in patients aged 11 to 17 years. Emergency medical assistance was required mainly at night on weekdays by patients aged 11-17, 25-44 years and during the weekend and on weekdays by patients aged 18-24 years. A blood alcohol concentration higher than 50 mg/dL was found in more than 67% of patients aged 11-17 and 18-24 years at weekends. CONCLUSIONS: The most alarming finding from our data is that, despite prevention policies, young people requiring emergency medical assistance showed similar alcohol levels as adults and a high incidence of alcoholic coma.

Infliximab therapy restores adiponectin expression in perivascular adipose tissue and improves endothelial nitric oxide-mediated vasodilation in mice with type 1 diabetes.

Increased TNFα-mediated JNK signaling in the perivascular adipose tissue (PVAT) may contribute to the pathogenesis of vascular complications in T1DM by reducing adiponectin (Ad) synthesis and therefore impairing Ad-mediated activity in the contiguous blood vessel system. We evaluated whether in vivo treatment with the TNFα blocking antibody infliximab normalized expression of Ad and Ad receptors in various fat depots, and whether this effect correlated with improved endothelial activity and vasodilator function in streptozotocin (STZ)-induced diabetic mice. STZ mice were studied at 1 and 2weeks after diabetes onset, and compared to age-matched infliximab-treated diabetic (I-STZ) and control animals (CTRL) (n=10 each group). In STZ mice, activation of pro-inflammatory JNK signaling was faster in PVAT (P<0.01) than in visceral (VAT), epididymal (EAT) and subcutaneous (SAT) adipose depots, and associated with decreased Ad synthesis and dysregulated AdipoR1/R2 levels. In parallel, activation of JNK in aortic endothelial cells and mesenteric arteries was associated with decreased expression/phosphorylation of eNOS and impaired ACh-mediated vasodilation (P<0.05 vs. CTRL). Treatment with infliximab abrogated JNK activation, ameliorated Ad protein expression, and normalized expression of both AdipoR1 and AdipoR2 in PVAT, concomitantly improving eNOS expression and vessel relaxation in mesenteric arteries from I-STZ mice (P<0.01 vs. STZ). These observations underline the early susceptibility of PVAT to activation of pro-inflammatory JNK signaling, and highlight its potential importance in early vascular changes of T1DM. Further elucidation of the role of PVAT in cardiovascular complications may allow for the design of novel therapeutic strategies directly addressing PVAT pathophysiology.

Males with low serum levels of vitamin D have lower pregnancy rates when ovulation induction and timed intercourse are used as a treatment for infertile couples: results from a pilot study.

BACKGROUND: Vitamin D (Vit D) is important for the regulation of reproductive physiology. In humans, maternal Vit D deficiency has been implicated in several reproductive- and pregnancy-related disorders. Very few data are available regarding the Vit D status in male partners of couples attempting pregnancy. This observational study (IRB Prot. N. 078/13) aimed to evaluate whether low Vit D serum levels in males might decrease the rate of successful conception in couples attempting pregnancy. METHODS: Male and female partners of infertile couples (n = 102) were classified into 2 GROUPS according to normal (≥30 ng/ml) or low (below 30 ng/ml) serum Vit D levels in male partners. Semen analysis was performed in each male participant based on the WHO reference criteria. The female partners of both groups were subjected to 3 consecutive cycles of gonadotropin-induced mono-ovulation. The main outcome measures included the clinical pregnancy rate, delivery per patient and per cycle, and miscarriage rate between the 2 groups evaluated at the end of the three-month period of the study. RESULTS: In male partners of both groups, standard semen analysis did not highlight substantial differences in sperm concentration, sperm progressive motility, or typical form. The pregnancy rates per patient and per cycle and delivery rates per patient and per cycle were all significantly higher (p< 0.05) in couples with normal Vit D levels. CONCLUSIONS: These results suggest the existence of a relationship between male Vit D serum levels and semen ability to begin a pregnancy during cycles of timed vaginal intercourse.

Intermittent low-dose finasteride administration is effective for treatment of hirsutism in adolescent girls: a pilot study.

STUDY OBJECTIVE: Hirsutism has negative impact on adolescent psychosocial development for both cosmetic and endocrine reasons. This study evaluated the effectiveness of a new intermittent, low-dose finasteride regimen consisting of 2.5 mg of drug given every 3 days (1 day of treatment, 2 days of drug withdrawal) for 6 months in girls with hirsutism by polycystic ovarian syndrome (PCOS) or idiopathic hirsutism (IH). DESIGN AND PARTICIPANTS: Twenty-eight girls (15-19 y old) with hirsutism were randomly assigned to 2 treatment groups and treated for 6 months. Fourteen patients (7 with IH, 7 with PCOS) received finasteride; fourteen patients (7 with IH, 7 with PCOS) received placebo. Hirsutism score (HS), clinical, and hormonal effects were compared between the 2 groups. RESULTS: In patients treated with finasteride, the HS value at 6 months was 52.9% lower than that observed at baseline in girls with IH, and 52.8% lower in girls with PCOS (P < .0001 for both). Similarly, the 3α-17 ß-androstenediol glucuronide serum levels were decreased by 34.8% in patients with IH, and by 47.5% in patients with PCOS (P < .0001, respectively). Finasteride treatment was well tolerated and did not alter values of BMI, serum levels of sexual hormones, metabolic parameters related to liver and kidney function as well as glycemic and lipidic asset. CONCLUSIONS: A low-dose of finasteride, given every 3 days, reduces the HS in young patients affected by PCOS or IH. Compared with conventional continuous finasteride administration, the intermittent low-dose regimen has similar efficacy with the advantage to be safer and less expensive.
