Risks and Benefits of Ultrasound, Nerve Stimulation, and Their Combination for Guiding Peripheral Nerve Blocks: A Retrospective Registry Analysis.

Ultrasound, nerve stimulation, and their combination are all considered acceptable ways to guide peripheral nerve blocks. Which approach is most effective and associated with the fewest complications is unknown. We therefore used a large registry to analyze whether there are differences in vascular punctures, multiple skin punctures, and unintended paresthesia.

Solarium Use and Risk for Malignant Melanoma: Meta-analysis and Evidence-based Medicine Systematic Review.

There is an ongoing debate whether solarium use (indoor tanning/artificial UV) may increase the risk for primary cutaneous malignant melanoma.

The Impact of UV-dose, Body Surface Area Exposed and Other Factors on Cutaneous Vitamin D Synthesis Measured as Serum 25(OH)D Concentration: Systematic Review and Meta-analysis.

To optimize public health campaigns concerning UV exposure, it is important to characterize factors that influence UV-induced cutaneous vitamin D production. This systematic review and meta-analysis investigated the impact of different individual and environmental factors including exposed body surface area (BSA), UVB dose and vitamin D status, on serum 25(OH)D concentration.

Echocardiographic criteria to detect unicuspid aortic valve morphology.

Unicuspid aortic valve (UAV) is a rare congenital malformation associated with severe aortic stenosis or regurgitation. This study aimed to systematically determine echocardiographic criteria to identify UAV.

The association between different features of sleep-disordered breathing and blood pressure: A cross-sectional study.

Sleep disordered breathing (SDB) is highly prevalent in patients with high blood pressure (BP). Severity of SDB can be evaluated by the number of apneas and hypopneas per hour (AHI) or by measures of hypoxia. The objective of this study was to assess the association between different measures of SDB and BP. In 134 consecutive patients, polygraphy was performed to determine the AHI. Pulse oximetry was used to determine hypoxemic burden (time below 90% oxygen saturation [T90] and hypoxia load [HL], representing the integrated area above the curve of desaturation). AHI did not correlate with systolic and diastolic BP or pulse pressure. In contrast, HL correlated with pulse pressure during the day (P = .01) and night (P = .0034) before and after adjustment for body mass index. The correlation between systolic BP and HL at night disappeared following adjustment for body mass index. This study generates the hypothesis that nocturnal hypoxemic burden may represent a suitable marker of BP pattern and a potential treatment target in hypertensive patients.

Longitudinal magnetic resonance imaging in progressive supranuclear palsy: A new combined score for clinical trials.

Two recent, randomized, placebo-controlled phase II/III trials ( NCT01110720, NCT01049399) of davunetide and tideglusib in progressive supranuclear palsy (PSP) generated prospective, 1-year longitudinal datasets of high-resolution T1-weighted three-dimensional MRI.

Biomarkers and Functional Decline in Prodromal Alzheimer's Disease.

Little is known of possible associations between Alzheimer's disease (AD) biomarkers and instrumental activities of daily living (IADL) change over time.

Elective neck dissection in unilateral carcinomas of the tongue: Unilateral versus bilateral approach.

Elective neck dissection (END) is a common primary treatment strategy for oral tongue squamous cell carcinoma (OTSCC), although uncertainty remains regarding the necessary extent of END for strictly unilateral early stage OTSCC. The authors evaluated two END variations, unilateral and bilateral, to determine the optimal extent.

Two decades of experience with root remodeling and valve repair for bicuspid aortic valves.

Bicuspid aortic valve anatomy is associated with ascending aortic aneurysm in approximately 50% of individuals and may lead to severe aortic regurgitation with aortic dilatation. Both entities may be treated by valve repair and root remodeling. The objective was to review the cumulative experience of 20 years.

Photobiomodulation therapy in breast cancer-related lymphedema: a randomized placebo-controlled trial.

The aim of our study was to examine the effects of photobiomodulation therapy (PBMT) in the treatment of breast cancer-related lymphedema using a compactly designed treatment regime consisting of eight therapy sessions in combination with a cluster laser device covering a total area size of 78.54 cm² over the axillary.

Clinical practice audit concerning antimicrobial prophylaxis in paediatric neurosurgery: results from a German paediatric oncology unit.

Perioperative antimicrobial prophylaxis (PAP) has been identified as an important target for internal audits, concerning the judicious use of antibiotics. Paediatric oncology patients with brain tumours face an increased risk of surgical site infection (SSI) after neurosurgery and receive routine PAP in this setting.

Less pain after transvaginal cholecystectomy: single-center pooled analysis.

We previously reported outcome after transvaginal cholecystectomy (TVC) from two cohort studies and a randomized controlled trial. We now present a pooled analysis of postoperative pain scores.

Long-term outcomes in radically treated synchronous vs. metachronous oligometastatic non-small-cell lung cancer.

Radical treatment for oligometastatic non-small-cell lung cancer (NSCLC) has a curative potential for selected patients. The present retrospective study was designed to examine the relevance of synchronous vs. metachronous manifestations as a potential prognostic factor when ablative treatments are performed in oligometastatic disease.

Power calculations and placebo effect for future clinical trials in progressive supranuclear palsy.

Two recent randomized, placebo-controlled trials of putative disease-modifying agents (davunetide, tideglusib) in progressive supranuclear palsy (PSP) failed to show efficacy, but generated data relevant for future trials.

Amyloid-β Protein Precursor Cleavage Products in Postmortem Ventricular Cerebrospinal Fluid of Alzheimer's Disease Patients.

Accumulation and aggregation of amyloid-β (Aβ) are considered etiologic processes in Alzheimer's disease (AD). However, the roles of other AβPP cleavage products in disease pathology remain elusive. Here, we measured levels of the major secreted AβPP processing products sAβPPα, sAβPPβ, and Aβ species in postmortem collected ventricular CSF of 196 AD patients and 74 controls. In AD we identified Aβ₄₂ to decrease continuously with progressing Braak stages, whereas Aβ₄₀ was upregulated in early stages of the disease (Braak stage 4) and down-regulated with progressing pathology. Interestingly, both sAβPPα and sAβPPβ were upregulated in AD as compared to controls (sAβPPα, p = 0.02; sAβPPβ, p = 0.01). Moreover, we observed a strong positive correlation of both alternative AβPP processing products, sAβPPα and sAβPPβ (r²= 0.781; p <  0.0001). Together, our results argue for generally enhanced AβPP processing in AD patients and emphasize the necessity of analyzing the roles of all AβPP processing products in AD pathology.

Predictors of Societal Costs in Dementia Patients and Their Informal Caregivers: A Two-Year Prospective Cohort Study.

Dementia poses a substantial economic burden on society. Knowing which factors predict high costs in dementia may help to better target interventions and optimize resource allocation. This study aimed to identify predictors of the total societal costs in dementia patients and their informal caregivers.
