Clinical TrialDiuretic use, RAAS blockade and morbidity in elderly patients presenting to the Emergency Department with non-specific complaints.
Up to 20% of elderly patients present to the emergency department (ED) with non-specific complaints (NSC), such as "generalised weakness", the majority suffering from serious conditions requiring timely intervention. Little is known about the use and influence of diuretics and renin-angiotensin-aldosterone (RAAS) blockade on morbidity in those patients. The hypothesis was tested that the use of diuretics and RAAS blockade could be associated with an increased incidence of serious conditions in those patients. ⋯ Treatment with two or more diuretics, loop diuretics, or a combination therapy with RAAS blockade and diuretics are independently associated with serious condition and therefore should be recognized as "red flags" in elderly patients presenting to the ED with NSC.

The GC, CYP2R1 and DHCR7 genes are associated with vitamin D levels in northeastern Han Chinese children.
Vitamin D deficiency is associated with risk in several diseases. Vitamin D status has high heritability, yet the genetic epidemiology of vitamin D or its metabolites has not been well studied. Our objective was to identify the relationship among three vitamin D-related genes (GC, CYP2R1 and DHCR7/NADSYN1) and the levels of 25(OH)D in northeastern Han Chinese children. ⋯ The two SNPs in GC (rs222020, rs2298849), four SNPs in CYP2R1 (rs10741657, rs10766197, rs12794714 and rs1562902) and two SNPs in DHCR7/NADSYN1 (rs3829251, rs12785878) were significantly associated with plasma 25(OH)D concentrations under both additive and recessive models (P <0.05). The genotypes of the CYP2R1 rs2060793 polymorphism showed positive association with serum 25(OH)D status under all of the three genetic models even after correction for multiple comparison. This population-based study was the first to confirm the strong effects of the GC, CYP2R1 and DHCR7/NADSYN1 loci on circulating 25(OH)D concentrations in northeastern Han Chinese children.

Comparative StudyTENS - an alternative to antiviral drugs for acute herpes zoster treatment and postherpetic neuralgia prevention.
To evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) in treatment of Herpes zoster (HZ), and prevention of postherpetic neuralgia (PHN) compared with antiviral drugs. PHN is frequent complication of HZ and may last for months, its treatment isn't very successful. Nonpharmacological regimens for treatment of HZ and prevention of PHN haven't been evaluated. ⋯ Study suggests TENS may be safe adjunct or even alternative to antiviral drugs for treatment of acute HZ. It looks that TENS may be at least as good as antiviral drugs for treatment of HZ, and it may be better in reducing and preventing PHN - such conclusion would necessitate controlled, prospective study. Use of TENS provided pain relief and resolution of skin lesions with no higher rate of other HZ complications compared to antiviral therapy.

Comparative StudyPrevalence of multimorbidity in medical inpatients.
To validate the estimates of the prevalence of multimorbidity based on administrative hospital discharge data, with medical records and chart reviews as benchmarks. ⋯ Estimates of the prevalence of multimorbidity in medical inpatients based on administrative data, chart reviews and medical records were very high and congruent for the different definitions of multimorbidity. Agreement for rating multimorbidity based on the different data sources was moderate to good. Administrative hospital discharge data are a valid source for exploring the burden of multimorbidity in hospital settings.

Comparative StudySun protective behaviour of primary and secondary school students in North-Western Switzerland.
The skin cancer incidence in Switzerland is one of the highest in Europe and still on the rise. Sun protection is the main preventive measure and of utmost importance during childhood and adolescence, since sunburns within these early phases of life increase the risk of developing skin cancer in adulthood. ⋯ In order to reduce the incidence of skin cancer in Switzerland, it is essential to improve children's and adolescents' sun protective behaviour. Future skin cancer prevention campaigns should teach proper use of sunscreen, and emphasise the value of wearing clothing and seeking shade as the most effective sun protection. Furthermore, major efforts are needed to change adolescents' attitude towards a suntan.
