Objectives Lipoatrophy is a long-term adverse effect of some antiretrovirals that affects quality of life, compromises adherence and may limit the clinical impact of HIV treatments. This paper explores the effect of tenofovir/emtricitabine ( TDF/ FTC) on the amount of limb fat in patients with virological suppression. Methods A randomized, prospective clinical trial was performed to compare continuation on a zidovudine/lamivudine ( ZDV/3TC)-based regimen with switching to a TDF/ FTC-based regimen in terms of the effect on limb fat mass as assessed by DEXA over a 72-week period. Results Eighty patients were included (39 in the TDF/ FTC arm and 41 in the ZDV/3 TC arm) and 73 completed the study (37 and 36, respectively). In the switch arm, limb fat increased by a median of 540 g from baseline ( P = 0.022), while in the ZDV/3TC arm it decreased by a median of 379 g ( P = 0.112; p between groups = 0.007). Subjects with baseline limb fat ≤ 7200 g, previous time on ZDV > 5 years or a body mass index > 25 kg/m2 experienced higher limb fat gains than other subjects, and these differences were statistically significant. Haemoglobin increased by a median of 1.0 g/d L in the TDF/ FTC arm ( P < 0.001) and remained unchanged in the ZDV/3TC arm (p between groups = 0.0002). There were no significant differences between groups in other secondary endpoints (body weight, total body and trunk fat content, total body bone mineral density, laboratory parameters, CD4 cell count and viral load). Conclusions Switching from a ZDV/3TC-based to a TDF/ FTC-based regimen led to a statistically significant improvement in limb fat, in contrast to the progressive loss of limb fat in subjects continuing ZDV/3TC.

Aims To update the existing scientific evidence on the efficacy of local antimicrobials as adjuncts to subgingival debridement in the treatment of chronic periodontitis. Material and Methods Fifty-six papers were selected, reporting data from 52 different investigations. All the studies reported changes in probing pocket depth ( PPD) and clinical attachment level ( CAL) and most in plaque index (PlI) and/or bleeding on probing ( BOP). Meta-analyses were performed with the data retrieved from the studies fulfilling the inclusion criteria. Results The overall effect of the subgingival application of antimicrobials was statistically significant ( p = 0.000) for both changes in PPD and CAL with a weighted mean difference ( WMD) of −0.407 and −0.310 mm respectively. No significant differences occurred for changes in BOP and PlI. Subgingival application of tetracycline fibres, sustained released doxycycline and minocycline demonstrated a significant benefit in PPD reduction ( WMD between 0.5 and 0.7 mm). The rest of the tested outcomes demonstrated a high heterogeneity. The local application of chlorhexidine and metronidazole showed a minimal effect when compared with placebo ( WMD between 0.1 and 0.4 mm). Conclusions The scientific evidence supports the adjunctive use of local antimicrobials to debridement in deep or recurrent periodontal sites, mostly when using vehicles with proven sustained release of the antimicrobial.

Abstract: Objective: The aim of this paper is to explore the prevalence of psychiatric morbidity in different immigrant groups in Spain. In keeping with prior studies carried out in Europe, it is expected that the immigrant population will have elevated levels of psychopathology, with some variation across immigrant groups. Method: Design: Multicenter, observational, cross-sectional study. Setting: Primary care settings of two Spanish regions. Sample: N=1.503 immigrants paired with the same number of Spanish controls, adjusted by gender and age. Variables: Demographic variables, MINI International Neuropsychiatric Interview and Standardized Polyvalent Psychiatric Interview, somatic symptoms section. Student''s t tests, ORs and logistic regressions were used to analyze the data. Results: No differences in psychiatric morbidity were found (native born 30.9%, population vs. immigrants 29.6%, OR=.942, CI=.806–1.100) when comparing immigrants to native born Spaniards. Relative to Spaniards (30.9%), Latin American immigrants had significantly higher levels of psychopathology (36.8%), Sub-Saharan Africans (24.4%) and Asians (16%) had significantly lower levels, and Eastern Europeans (31.4%) and North Africans (26.8%) showed no significant difference. Conclusions: The hypotheses were only partially supported. Although overall immigrants did not differ from the native born population, when analyzed by geographic origin, only Latin Americans had higher levels of psychopathology. It is concluded that multiple factors need to be taken into consideration when studying the mental health of immigrants given that different immigrant groups have different levels of psychopathology.

Background: This study assesses the impact on safety of a system designed to enhance sleep in car passengers. The system holds the head posteriorly and limits its rotation in the sagittal and frontal planes, modifying the occupant's head position. This device may have an influence on the interaction between the occupant and the vehicle restraint systems. Methods: It was a randomised, prospective, single-blind, cross-over controlled study in which 41 volunteers were exposed to using the system while riding as car passengers. Whether the device influenced the posture of the occupants and prevented them from adopting out-of-position (OOP) configurations was also analysed. Occupants were videotaped while they were using both the innovative system (cases) and their normal sleeping device (controls), if any. Results: Controls were exposed to OOP situations in 825 occasions (18.4%; 95% CI 17.3% to 19.6%), while cases were exposed in 416 occasions (9.3%; 95% CI 8.4% to 10.2%). The paper also analysed how many cases and controls were exposed at least once to a particular event and how frequent a single participant incurred in an OOP situation. In both cases, the innovative device showed a reduction in exposition. When OOP situations were grouped into severe, moderate and minor events, the innovative device produced a statistically significant reduction in the occurrence of severe and moderate events. Conclusions: A device originally designed to improve comfort and rest in car passengers has been found to reduce the exposure of the occupants to being OOP while resting in the car.

The article focuses on a study with regards to the use of reporting guidelines such as CONSORT and STROBE for the improvement of manuscript quality in biomedical journals. It says that the subject of the study were the research manuscripts acquired by the journal "Medicina Clínica" from May 2008 to April 2009. Results show that 34 papers were rejected from the 126 papers for conventional peer review, wherein the additional review shows an improvement in the quality of the manuscripts.
