ABSTRACT

ABSTRACT: There is lack of empirical findings on a direct link between suicidality and dependency in youth. This is particularly relevant for children and adolescents with a trauma history, since traumatization is a well-established risk factor for suicidality in this population. Research on dependency predominantly uses self-report assessments, which may be susceptible to biases. In this study, performance-based interpersonal dependency scores in inpatient children and adolescents with trauma history were compared with patients' suicidal behavior (suicidal ideation and suicidal attempts) as derived from chart records. The results showed a gender effect. High dependency scores were associated with higher suicidal ideation for girls and with lower suicidal attempts for boys. These findings demonstrate that a relationship between dependency and suicidality for hospitalized traumatized youth is impacted by gender.

ABSTRACT

The standard procedure for blood glucose measurements is enzymatic testing. This method is cheap, but requires small samples of open blood with direct contact to the test medium. In principle, NMR provides non-contact analysis of body fluids, but high-field spectrometers are expensive and cannot be easily utilized under clinical conditions. Low-field NMR systems with permanent magnets are becoming increasingly smaller and more affordable. The studies presented here aim at exploring the capabilities of low-field NMR for measuring glucose concentrations in whole blood. For this purpose, a modern 1 T benchtop NMR spectrometer was used. Challenges arise from broad spectral lines, the glucose peak locations close to the water signal, low SNR and the interference with signals from other blood components. Whole blood as a sample comprises even more boundary conditions: crucial for reliable results are avoiding the separation of plasma and cells by gravitation and reliable reference values. First, the accuracy of glucose levels measured by NMR was tested using aqueous glucose solutions and commercially available bovine plasma. Then, 117 blood samples from oral glucose tolerance testing were measured with minimal preparation by simple pulse-acquire NMR experiments. The analysis itself is the key to achieve high precision, so several approaches were investigated: peak integration, orthogonal projection to latent structure analysis and support vector machine regression. Correlations between results from the NMR spectra and the routine laboratory automated analyzer revealed an RMSE of 7.90 mg/dL for the best model. 91.5% of the model output lies within the limits of the German Medical Association guidelines, which require the glucose measurement to be within 11% of the reference method. It is concluded that spectral quantification of glucose in whole blood samples by high-quality NMR spectrometers operating at 1 T is feasible with sufficient accuracy.

ABSTRACT

Published research findings are the basis for health care decisions or further medical research. However, reporting of research methods and findings is often incomplete and of insufficient quality. Poor reporting hampers the assessment of reliability and validity of study results. Strengths and weaknesses of the investigation cannot be completely evaluated and subsequently it can mislead decision making in health care or in further clinical research. Transparent reporting can help minimize misinterpretation of publications. Several guidelines were developed to provide advice for reporting research methods and findings. These reporting guidelines facilitate critical appraisal and interpretation of the studies. The guidelines specify in form of checklists a minimum set of items required for clear and transparent reporting. The checklists focus on design, conduct and analysis of studies in particular issues that might introduce bias into the research. The application of these reporting guidelines is required by many international journals. In this CME article we present guidelines for reporting of randomized controlled trials (CONSORT), observational studies (STROBE) and systematic reviews and meta-analyses (PRISMA, MOOSE).

ABSTRACT

BACKGROUND: This pilot study compared a monophasic hyaluronic acid dermal filler with a biphasic filler for the correction of nasolabial folds. METHODS: Participant- and assessor-blinded, randomized clinical trial involving participants with moderate to severe nasolabial folds. Split-face design comparing a monophase hyaluronic acid (HA) filler (mono-HA) with a biphasic HA filler (bi-HA). Injection with touch-up after 1 month. Wrinkle improvement was measured before and after injection and after 1, 2, 4, and 7 months, using the Wrinkle Severity Rating Scale and the Global Aesthetic Improvement Scale as outcome criteria. An optional treatment was offered at the end of the study, with participants allowed to choose one of the products. OBJECTIVE: Evaluation of efficacy and safety of both products. RESULTS: Both products showed immediate, good results after injection and touch-up and demonstrated good durability over time. Participant preference for optional treatment at the end of the study favoured mono-HA. Both products were well tolerated, without serious adverse events. CONCLUSION: The effect after injection of mono-HA and bi-HA is generally comparable, although there was a trend in favor of mono-HA. Materials and funding for this study were provided by Teoxane, Geneva, Switzerland.

ABSTRACT

BACKGROUND: Adverse reactions to injectable filler may be challenging to treat. The spectrum of treatment options ranges from immunomodulatory drugs (e.g., glucocorticosteroids) to antibiotics to laser therapy and surgery. OBJECTIVES: To assess how adverse reactions were treated and how they processed over time. MATERIALS AND METHODS: Participants from the Injectable Filler Safety (IFS) Study were reinterviewed to obtain data on the course of adverse reactions and the therapy. RESULTS: Forty-one participants from the IFS Study were reinterviewed; 35 (85%) received treatment, 17 (41%) with a combination of drug therapy and surgery, 14 (34%) with drug therapy only, and four (10%) with a surgical intervention. Six (15%) did not receive any treatment. Fifty-one percent of all of the treated participants reported treatment-related adverse reactions. Participants with more severe adverse reactions were more likely to be treated with a combination of drugs and surgery. In all participants, adverse reactions improved. CONCLUSION: We certainly need more evidence. Reporting positive and negative treatment outcomes is important to improve our knowledge regarding these reactions. Therefore, registries focusing on adverse reactions to injectable fillers and their treatment should be encouraged. The authors have indicated no significant interest with commercial supporters.

ABSTRACT

Volume augmentation of the back of the hand is a new technique which is not yet often employed. We describe the treatment of two patients who received hyaluronic acid products produced by Q-Med (Macrolane VRF20, Restylane Vital and Vital Light). The injections of Macrolane VRF 20 were done by feathering technique using a long and blunt 18 gauge canula while Restylane was injected by tunneling or tenting technique with a 30 gauge needle. Significant adverse events did not occur. After injection of the hyaluronic acid fillers, the appearance of the back of the hands was improved. Both patients were very satisfied with the result.

ABSTRACT

BACKGROUND: For the glabellar region, severe partly vascular adverse events have been reported after treatment with injectable fillers. METHODS AND MATERIALS: For this study, data from the Injectable Filler Safety Study, a German-based registry for those reactions, was analyzed to characterize adverse events seen in the glabellar region. Patients were analyzed descriptively. RESULTS: Forty of 139 registered patients reported adverse events in the glabellar region. All patients were female, with an average age of 52.3. Nineteen patients with adverse reactions to hydroxyethylmethacrylate (HEMA) and ethylmethacrylate (EMA) in a fixed combination with hyaluronic acid (HA) and 10 patients with adverse reactions to different hyaluronic acid products were reported; five patients reacted to poly-L-lactic acid (PLA). The most common adverse reactions to HEMA/EMA in HA and PLA were nodules and hardening. In HA-treated patients, erythema and inflammation, swelling, and pain were most frequent. The adverse reactions to HEMA/EMA in HA were severe in 50% of the patients. Severe adverse reactions were found to a lesser extent in patients treated with HA and PLA. Potential vascular complications were documented in only two patients. CONCLUSION: Adverse reactions seen in the glabella are overwhelmingly product associated and to a lesser extent location associated. Vascular complications with necrosis and ulceration were rare.

ABSTRACT

BACKGROUND: Injectable fillers are widely used in aesthetic medicine. Polylactic acid (PLA) is a semipermanent filler that needs to be diluted with sterile water before injection. PLA has been associated with an increased risk of adverse reactions, specifically nodule formation. OBJECTIVE: To describe adverse reactions to PLA and potential risk factors based on a partly population-based registry over an 8-year period. METHODS: The Berlin registry is a partially population-based registry where dermatologists, plastic surgeons, and other specialists are contacted regularly and asked to report patients with adverse events to injectable fillers substances. Additional patients were derived from private practices outside of Berlin. The patients were assessed with a standardized questionnaire. The results were mainly analyzed by descriptive measures. RESULTS: Twenty-two patients (age, 47.82 +/- 12.65 years) with adverse reactions to PLA were included. The most frequent adverse reaction was nodule formation found in all patients. In 13 (59.1%) of the cases, nodule formation was considered to be severe. Nodules appeared after a mean latency period of 6.00 +/- 5.84 months. The duration of the adverse reactions until the interview was 14.32 +/- 10.13 months. The frequency of patients with adverse events to PLA was found to decrease after new recommendations concerning the dilution of the product were launched. CONCLUSION: PLA is an injectable filler substance that may cause subcutaneous nodules in treated patients. Our data support a decreased risk of adverse reactions with an increased dilution. However, nodule formation still appears to be a characteristic feature of PLA.
