OBJECTIVE: To evaluate the impact of manual vibrocompression and nasotracheal suctioning on heart (hr) and respiratory (rr) rates, peripheral oxygen saturation (SpO2), pain and respiratory distress in infants in the postoperative period of a cardiac surgery. METHODS: Randomized controlled trial, in which the assessments were performed by the same physiotherapist in two moments: before and after the procedure. The infants were randomly divided into two groups: Intervention (IG), with manual chest vibrocompression, nasotracheal suctioning and resting; and Control CG), with 30 minutes of rest. Cardiorespiratory data (SpO2; hr; rr) were monitored and the following scales were used: Neonatal Infant Pain Scale (NIPS), for pain evaluation, and Bulletin of Silverman-Andersen (BSA), for respiratory distress assessment. The data were verified by analysis of variance (ANOVA) for repeated measures, being significant p<0.05. RESULTS: 20 infants with heart disease, ten in each group (seven acyanotic and three cyanotic) were enrolled, with ages ranging from zero to 12 months. In the analysis of the interaction between group and time, there was a significant difference in the variation of SpO2 (p=0.016), without changes in the other variables. Considering the main effect on time, only rr showed a significant difference (p=0.001). As for the group main effect, there were no statistical differences (SpO2 - p=0.77, hr - p=0.14, rr - p=0.17, NIPS - p=0.49 and BSA - p=0.51 ). CONCLUSIONS: The manual vibrocompression and the nasotracheal suctioning applied to infants in postoperative of cardiac surgery did not altered SpO2 and rr, and did not trigger pain and respiratory distress.

BACKGROUND Depression and anxiety are growing issues for college students, with both aerobic-resistance training and mindfulness-yoga exercises known to be effective in reducing symptoms and severity. However, no known research is available comparing these two depression and anxiety interventions simultaneously and in a virtual environment. OBJECTIVE This study aimed to determine the effects of a virtual aerobic-resistance exercise intervention (WeActive) and a virtual yoga-mindfulness mindfulness exercise intervention (WeMindful) on depression and anxiety symptoms in college students METHODS The participants were 78 college students who anonymously completed a Qualtrics survey including the Generalized Anxiety Disorder Scale (GAD-7) and the Major Depression Inventory (MDI) at baseline and the post-test. Participants were randomly assigned to either the WeActive or WeMindful group and underwent two 30-minute virtual aerobic-resistance exercise lessons or yoga-mindfulness lessons per week for eight weeks. RESULTS The results of ANCOVA with repeated measures indicated that, while not statistically significant, both groups showed a notable decrease in anxiety with a marginal significant main effect of time (F = 3.485, p = 0.066, η2 = 0.047) but no significant main effect of group and no significant interaction effect of time with group. The two intervention groups experienced a significant decrease in depression with the main effect of time (F = 3.892, p = 0.052, η2 = 0.052). There was no significant main effect of group or interaction effect of time with group for depression. CONCLUSIONS College students in both WeActive and WeMindful groups experienced a significant decrease in depression symptoms and a decrease, though not significant, in anxiety as well. The study suggests that virtual WeActive and WeMindful interventions are effective approaches to managing US college student depression and anxiety during a pandemic.

AimsRecent conclusive evidence has suggested that, contrary to previous limited evidence, there is no benefit to the use of 3% hypertonic saline (3% HS) in the treatment of bronchiolitis in infants.1,2 This led to a change in the clinical guideline during the 2015/2016 bronchiolitis season. We hypothesised that the use of hypertonic saline was preventing the use of other un-necessary treatments and that inappropriate prescribing would increase following the advice not to give hypertonic saline.The primary aim of the study was to determine if the removal of 3% hypertonic saline from the institutional clinical guideline would result in reduced prescribing patterns. A secondary aim was to evaluate the overall prescribing compliance with the guideline including in the prescribing of antibiotics and bronchodilators, and identify if the change in the clinical guideline impacted the prescribing of other agents in children admitted with a diagnosis of bronchiolitis.MethodsData on medical treatments and hospital outcomes were prospectively collected on all infants in the 2015/2016 season both before and after the change in guideline. Details of all medicines prescribed on the patients Medication Record particularly bronchodilators, antimicrobials and inhaled agents were collected. Patient demographics were collected from medical notes. Results were analysed using chi square and Mann Whitney in Excel and Stata.Results128 children (86 before, 42 after the change in guideline) were recruited to the study. Baseline demographics were similar except for a higher proportion of children with RSV in the pre-group. Overall guideline compliance was achieved by 2 infants pre, and 3 infants post guideline change (4%). The use of hypertonic saline decreased significantly after the change in guideline but did not cease (90% pre, 71% post p<0.01). Bronchodilators were used in one in 4 infants and antibiotics in one in 3 infants, and there was no significant difference in these rates before or after the change in guidelines.ConclusionThe change to the guideline reduced the use of 3%HS, however overall guideline compliance in children with bronchiolitis is poor. Hypertonic saline use decreased when the guideline changed but a significant portion of children before and after the guideline change received medications not indicated in the treatment of bronchiolitis, including bronchodilators and antibiotics. It appears that it remains difficult to ‘do nothing’ for bronchiolitis. Poor clinical practice remains and education of clinical staff is necessary in this regard.ReferencesGuidance: Bronchiolitis in children: diagnosis and management, NICE (NG9) Published date: June 2015.Silver AH, Esteban-Cruciani N, Azzarone G, et al. 3% hypertonic saline versus normal saline in inpatient bronchiolitis: A randomised controlled trial.

Background: The prevalence of diabetes have increased globally to epidemic proportions; glycemic control and treatment remains a challenge. Concurrent aerobic and resistance training programs (CART) have been widely recommended as an important strategy to improve physiologic and functional performance. Objective: The impact of CART programs on metabolic profile, glycemic control and exercise capacity status in patients with diabetes requires additional study, which is the primary aim of the current study. Materials and Methods: We evaluated 41 patients (15 female and 19 male, 50.8±7 years) with a confirmed diagnosis of diabetes. The subjects were randomized in two groups: sedentary group (SG) and CART group (CART-G). CART was performed 12 weeks, 3 times a week for approximately 1 hour per session (30 minutes aerobic and 30 minutes resistance). Body habitus was assessed by body mass index, waist circumference, and skinfolds. Peripheral muscular strength was evaluated by an isokinetic dynamometer and pulmonary gas exchange was measured breath-by-breath, using a portable telemetric system during maximal incremental exercise testing on a cycle ergometer. Statistical analysis included Shapiro-Wilk test follow by ANOVA two way repeated measures. Results: We observed a decrease in HbA1c (8.1±1.6 to 7.3±1.2%), cholesterol (198.38.1±50.3 to 186.8±35.1 mg/dL) and HOMA IR (6.4±6.8 to 5.0±1.4) in the CART-G compared to the SG. There was no significant difference in fasting plasma glucose. Although body weight did not significantly change after training, skinfold measurements indicated decreased body fat in the CART-G only. CART significantly enhanced muscle strength (p<0.05) (peak torque: 135.5±4 to 159.7±47.7 N.m) compared to the SG (Peak torque: 145.3±47.9 to 143±42.2 N.m). CART was also associated with a significant increase in peak oxygen consumption, from 22.9±6.1 to 27.2±4.7 ml•kg –1 •min –1 compared to the SG, from 21.7±4.5 to 21±3.3 ml•kg –1 •min –1 as well as the maximal workload (124.6±29.1 to 149.9±29 watts) compared to the SG (123.6±36.9 to 122.1±32.9 watts). Conclusion: We concluded that CART is an important intervention strategy, producing both physiologic and functional improvements, in patients with diabetes.

Introduction: Exposure to noxious stimuli can cause pain in infants. This study was conducted to evaluate the effects of the lavender oil inhalation on the pain resulting from the pentavalent vaccination. Methods: This clinical trial consisted of two groups: the lavender oil group with 42 infants and the placebo group with 57 infants. The healthy infants without congenital abnormalities in need of pentavalent vaccine also participated in our study. The infants started the lavender oil or placebo aromatherapy one minute before injection. The pain was assessed three times, using the Neonatal Infant pain Scale (NIPS): before vaccination, 15 s, and 5 min after vaccination. Also, the duration of crying was measured in both groups. Results: At baseline, the two groups were similar in relation to the NIPS scores. While, after 5 minutes, the NIPS score was significantly lower in the lavender group. Based on the repeated measures analysis, the NIPS score changed over time totally. However, the two groups were significantly different in relation to the NIPS score over time. The duration of crying was 75.47 (60.675) second in the lavender group and 105.22 (75.739) s in the control group. The statistical test showed a significant difference between the two groups. Conclusion: A low concentration of the lavender oil inhalation can reduce the pain and improve soothing in the infants with the pentavalent vaccine injection.

D Dimer

A low intake of selenium is associated with increased cardiovascular mortality. This could be reduced by supplementation with selenium and coenzyme Q10. D-dimer, a fragment of fibrin mirroring fibrinolysis, is a biomarker of thromboembolism, increased inflammation, endothelial dysfunction and is associated with cardiovascular mortality in ischemic heart disease. The objective was to examine the impact of selenium and coenzyme Q10 on the level of D-dimer, and its relationship to cardiovascular mortality. D-dimer was measured in 213 individuals at the start and after 48 months of a randomised double-blind placebo-controlled trial with selenium yeast (200 µg/day) and coenzyme Q10 (200 mg/day) (n = 106) or placebo (n = 107). The follow-up time was 4.9 years. All included individuals were low in selenium (mean 67 μg/L, SD 16.8). The differences in D-dimer concentration were evaluated by the use of T-tests, repeated measures of variance and ANCOVA analyses. At the end, a significantly lower D-dimer concentration was observed in the active treatment group in comparison with those on placebo (p = 0.006). Although D-dimer values at baseline were weakly associated with high-sensitive CRP, while being more strongly associated with soluble tumour necrosis factor receptor 1 and sP-selectin, controlling for these in the analysis there was an independent effect on D-dimer. In participants with a D-dimer level above median at baseline, the supplementation resulted in significantly lower cardiovascular mortality compared to those on placebo (p = 0.014). All results were validated with a persisting significant difference between the two groups. Therefore, supplementation with selenium and coenzyme Q10 in a group of elderly low in selenium and coenzyme Q10 prevented an increase in D-dimer and reduced the risk of cardiovascular mortality in comparison with the placebo group. The obtained results also illustrate important associations between inflammation, endothelial function and cardiovascular risk.

The Impact

Objective In an effort to reduce the primary cesarean delivery (CD) rate, the American College of Obstetricians and Gynecologists (ACOG) recommended new labor guidelines in 2014 that allow longer duration of labor times. There are little data on the impact of these guidelines on CD rates and pregnancy outcomes in a predominantly Hispanic population. This study aimed to compare the primary CD rates and maternal and neonatal outcomes in patients undergoing primary CD for arrest of labor before and after implementation of the 2014 guidelines. Study Design This was a retrospective cohort study of term patients who underwent a CD for an arrest disorder between January 2011 and April 2017 at a county teaching hospital. Our primary outcome was the composite maternal and neonatal morbidities (CMM and CNM, respectively). Differences in the demographic and clinical characteristics, CMM, and CNM stratified by time period (pre- vs. postimplementation) were examined. Results There were 4,976 deliveries in the study period: 525 (11%) underwent primary CD for arrest disorder; 298 (6%) prior to 2014, and 227 (5%) after 2014 (p = 0.62). There was no significant difference in the rate of CD between the two periods (13.4 vs. 13.3%, p = 0.81). In patients undergoing CD for arrest of dilation (n = 389), the CMM and CNM did not significantly change between both groups (63.3 vs. 56%, p = 0.15). In patients who had a CD for arrest of descent (n = 136), the rate of CMM significantly increased from 50 to 75% (p = 0.02) with no significant change in the CNM (13.2 vs. 20%, p = 0.3). Conclusion Despite significant changes in labor management after the publication of the 2014 guidelines, our primary CD rate was not reduced, and we noticed an increase in CMM in patients who had CD for arrest of descent. A randomized controlled trial is needed to further evaluate the effect of these guidelines nationally. Key Points

The Impact

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Abstract Background Neuropathic pain is characterized by spontaneous painful symptoms. Medical therapies include the use of a capsaicin 8% patch (Qutenza®, Grünenthal Gmbh, Germany), and patients may experience a sharp burning sensation at application and removal of the patch. This study aimed to evaluate the impact of playing a standardized hypnosis recording during application, on the pain and anxiety induced by capsaicin treatment. Methods In a randomized, controlled trial, we assessed the benefits of the intervention firstly on pain and secondly on anxiety, as measured using numerical rating scales. All patients had application of the capsaicin patch, including the possibility for the patient to apply a cold patch. Participants were randomly assigned to one of 3 groups, namely the “Standard group” (no intervention), “Hypnosis group”, in which a standardized hypnotic message was played during application, or the “Music group” in which relaxing music was played during application of the patch. Results Sixty-nine patients were included. Overall, there was no significant difference in pain scores between groups (p = 0.355). Compared to standard application, anxiety was significantly lower in the hypnosis group after application (p = 0.007), with no significant difference between the standard and music arms (p = 0.271), or between the hypnosis and music arms (p = 0.423). Conclusions Listening to a standardized hypnotic message during application of a capsaicin patch was found to significantly lower anxiety. These findings indicate that the use of a hypnotic message can reduce discomfort and warrant its evaluation in other indications of pain or anxiety during treatment procedures.

Abstract Background The incidence of Candida bloodstream infections has risen over the last several decades. Complications of candidemia include endogenous fungal endophthalmitis which can result in devastating outcomes including vision loss. In 2015, the IDSA guidelines were updated to recommend echinocandins as initial therapy for candidemia. Given the poor ocular penetration of echinocandins there has been some concern this change may portend an increased incidence of ocular complications in candidemic patients. We sought to examine whether patients who received empiric echinocandin therapy developed higher rates of ophthalmic complications of candidemia. Methods We identified patients in our healthcare system who had blood cultures positive for Candida species and a completed ophthalmology consult between January 1, 2014 and April 30, 2019. Chi-squared analysis was used to compare antifungal prescribing patterns before and after release of the updated IDSA guidelines. We assessed whether the switch to empiric echinocandin therapy as directed by the guidelines was associated with higher rates of abnormal eye exams. Results 47 patients treated before the guideline change were compared to 57 patients treated after the guideline change. There was no significant difference in age, gender, or comorbid diabetes and hypertension between the groups. Before the guideline change, 24/47 (51%) of patients received eye-penetrating antifungals. This decreased to 21/57 after the updated guideline (37%, p=0.21). The percentage of patients with positive eye exams was nearly equal before and after the updated guidelines, 10/47 (21%) before vs 13/57 (22%) after (p=1). After the guideline change, 7/21 (33%) of the patients treated with penetrating antifungals had positive eye exams vs 6/36 (16%) who received echinocandins (p=0.19). Conclusion Echinocandins are known to have poor ocular penetration yet our data demonstrate no change in the incidence of ophthalmic complications of candidemia after the 2016 guideline endorsed echinocandins as empiric therapy. The prevalence of positive eye exams throughout our study period was 22%, suggesting ongoing utility for these exams. Ongoing investigation is necessary to confirm and further study these findings.

SUMMARY The aim of this in vitro study was to quantitatively evaluate the internal gap of resin composites of high-and low-viscosity used in single- and incremental-fill techniques in Class I cavities exposed to thermal cycling (TC) using optical coherence tomography (OCT). Cavities of 4-mm depth and 3-mm diameter were prepared in 36 third molars randomly distributed into four groups, according to viscosity of restorative resin-based composite (high or low viscosity, all from 3M Oral Care) and technique application (bulk or incremental fill) used (n=9): RC, high-viscosity, incremental-fill, resin-based composite (Filtek Z350 XT Universal Restorative); BF, high-viscosity, bulk-fill, resin-based composite (Filtek One Bulk Fill); LRC, low-viscosity, incremental-fill, resin-based composite (Filtek Z350 XT Flowable Universal Restorative); and LBF, low-viscosity, bulk-fill, resin-based composite (Filtek Flowable Restorative). Single Bond Universal Adhesive system (3M Oral Care) was used in all the experimental groups. The incremental-fill technique was used for RC and LRC groups (2-mm increments), and a single-layer technique was used for BF and LBF groups, as recommended by the manufacturer. The internal adaptation of the resin at all dentin walls was evaluated before and after TC (5000 cycles between 5°C and 55°C) using OCT images. Five images of each restored tooth were obtained. Images were analyzed using ImageJ software that measured the entire length of the gaps at the dentin–restoration interface. The length of gaps (μm) was analyzed using two-way repeated measures ANOVA and the Tukey tests (α=0.05). There was a significant interaction between material types and TC (p=0.006), and a significant difference among all material types (p&lt;0.0001), before and after TC (p&lt;0.0001). Increased internal gaps at the dentin–restoration interface were noticed after TC for all groups. RC presented the lowest value of internal gap before and after TC, while LBF showed the highest values of internal gap after TC. In conclusion, TC negatively affected the integrity of internal gap, whereas high-viscosity, incremental-fill, resin-based composite presented better performance in terms of internal adaptation than low-viscosity, bulk-fill materials in Class I cavities.
