EFFECT OF HIGH AND LOW FLEXIBILITY ON AGILITY, ACCELERATION SPEED AND VERTICAL JUMP PERFORMANCE OF VOLLEYBALL PLAYERS

This study aimed to assess the effect of high and low levels of flexibility on key performance indicators of volleyball performance. Eighty-four volleyball players (n=84; mean±SD; decimal age: 16.57±1.51; height (cm): 176.23±8.77; body mass (kg): 66.14±11.79) were selected for the study. The design of the study was cross-sectional and to measure selected variables i.e. agility, lower body muscular power, and acceleration speed; 6×10 m shuttle run, countermovement jump (with arm swing) test and 20 m sprint test (standing start) were used. To measure the flexibility level of the players, sit and reach test was used. Shapiro-Wilk normality test was conducted to check the distribution of data and the Levine test was applied to check homogeneity of the variance in data. Participants were divided into two groups i.e. High Flexibility Group (HFG) and Low Flexibility Group (LFG) using k-means cluster analysis and independent t-test was applied to find the differences between HFG and LFG. The level of significance was set at p < 0.05. Results showed statistically significant difference between HFG and LFG in agility, acceleration speed and lower body muscular power and, based on the results, it was concluded coaches should include flexibility training in the regular training programme. The results obtained supported the rationale that baseline flexibility may influence the performance of volleyball players. Article visualizations

Impact of Pressure Control Ventilation and Volume Control Ventilation on oxygenation, pulmonary mechanics and haemodynamics during One Lung Ventilation in patients undergoing thoracic surgery: Arandomised controlled crossover study

Backgroud: Anaesthesia for thoracic surgery is nowadays performed with one lung ventilation (OLV) using volume control ventilation (VCV). Mechanical characteristics of pressure control ventilation (PCV) are thought to allow more homogenous distribution and improve oxygenation and reduce airway pressure so decrease chances of airway trauma and acute lung injury (ALI). This study was aimed to evaluate impact of two lung ventilation strategy (PCV/VCV) on oxygenation, pulmonary mechanics and haemodynamics during one lung ventilation in patient undergoing thoracic surgery.Method: After institutional ethical committee clearance this randomised single blind crossover study includes 30 patients of ASA I,II,III for elective thoracic surgery, using OLV and minimum duration of surgery of one hour were included in this study. Divided in two groups A and B using VCV first then PCV and vice versa. Haemodynamic parameters, ABG analysis and respiratory parameters were recorded, data collected and analysed by IBM SPSS statistics version 20.Results: Demographic, haemodynamic and ABG parameters were comparable in both groups higher Ppeak during VCV than PCV (p=0.004). Ppeak during OLV with VCV was significantly higher than during two lung ventilation (TLV) before starting OLV and end of the study (p&lt;0.05). Higher dynamic compliance in OLV – PCV group than OLV – VCV group (p&lt;0.001). Conclusion: PCV s a better ventilation mode than VCV in OLV with respect to reducing the incidence of barotrauma and ALI in patient undergoing elective thoracic surgery. Both modes are equivalent with respect to arterial oxygenation

Health-Related Social Needs Among Emergency Department Patients with HIV.

Little research has examined the health-related social needs of emergency department (ED) patients who have HIV. We surveyed a random sample of public hospital ED patients and compared the social needs of patients with and without HIV. Social needs were high among all ED patients, but patients with HIV reported significantly higher levels of food insecurity (65.0% vs. 50.3%, p = 0.01) and homelessness or living doubled up (33.8% vs. 21.0%, p &lt; 0.01) than other patients. Our findings suggest the importance of assessing social needs in ED-based interventions for patients with HIV

Risk Stratification of COVID-19 Patients Using Ambulatory Oxygen Saturation in the Emergency Department

Introduction: It is difficult to determine illness severity for coronavirus disease 2019 (COVID-19) patients, especially among stable-appearing emergency department (ED) patients. We evaluated patient outcomes among ED patients with a documented ambulatory oxygen saturation measurement.Methods: This was a retrospective chart review of ED patients seen at New York University Langone Health during the peak of the COVID-19 pandemic in New York City. We identified ED patients who had a documented ambulatory oxygen saturation. We studied the outcomes of high oxygen requirement (defined as &gt;4 liters per minute) and mechanical ventilation among admitted patients and bounceback admissions among discharged patients. We also performed logistic regression and compared the performance of different ambulatory oxygen saturation cutoffs in predicting these outcomes.Results: Between March 15–April 14, 2020, 6194 patients presented with fever, cough, or shortness of breath at our EDs. Of these patients, 648 (11%) had a documented ambulatory oxygen saturation, of which 165 (24%) were admitted. Notably, admitted and discharged patients had similar initial vital signs. However, the average ambulatory oxygen saturation among admitted patients was significantly lower at 89% compared to 96% among discharged patients (p&lt;0.01). Among admitted patients with an ambulatory oxygen saturation, 30% had high oxygen requirements and 8% required mechanical ventilation. These rates were predicted by low ambulatory oxygen saturation (p&lt;0.01). Among discharged patients, 50 (10%) had a subsequent ED visit resulting in admission. Although bounceback admissions were predicted by ambulatory oxygen saturation at the first ED visit (p&lt;0.01), our analysis of cutoffs suggested that this association may not be clinically useful.Conclusion: Measuring ambulatory oxygen saturation can help ED clinicians identify patients who may require high levels of oxygen or mechanical ventilation during admission. However, it is less useful for identifying which patients may deteriorate clinically in the days after ED discharge and require subsequent hospitalization.
