The result which was gained from this study is as follows. From the conclusion of this study it was confirmed that resistant motion at high level strength brings about rise in density of lactate in blood at the same time decline of muscular power and generates acute fatigue of nerve-muscle accompanied by decline in electrical activity of muscle. On the other hand explosive loading produced fatigue at body center and decline in nervine-muscular activity particularly for men, In case of women explosive load did not produce fatigue in the same level as men and they were also quicker in recovery after exercise. Based on 2 types of loading method used in this study there was clearly difference in the process of restoration from resistant motion. For greater decline in muscular power and electromyogram activity more longer period of recovery was require.

Awake intubation is indicated in difficult airways if attempts at securing the airway after induction of general anesthesia may lead to harm due to potential difficulties or failure in those attempts. Conventional awake flexible bronchoscopic intubation is performed via the nasal, or less commonly, oral route. Awake oral flexible bronchoscopic intubation (FBI) via a supraglottic airway device (SAD) is a less common technique; we refer to this as ‘supraglottic airway guided’ FBI (SAGFBI). We describe ten cases with anticipated difficult airways in which awake SAGFBI was performed. After sedation and adequate airway topicalization, an Ambu AuragainTM SAD was inserted. A flexible bronchoscope, preloaded with a tracheal tube, was then inserted through the SAD. Finally, the tracheal tube was railroaded over the bronchoscope, through the SAD and into the trachea. The bronchoscope and the SAD were carefully removed, whilst keeping the tracheal tube in-situ. The technique was successful and well tolerated by all patients, and associated complications were rare. It also offered the advantages of performing an ‘awake test insertion’ of the SAD, an ‘awake look’ at the periglottic region, and an ‘awake test ventilation.’ In certain patients, awake SAGFBI offers advantages over conventional awake FBI or awake videolaryngoscopy. More research is required to evaluate its success and failure rates, and identify associated complications. Its place in difficult airway algorithms may then be further established.

Primary cardiac lymphoma (PCL) comprises of 1%–2% of primary cardiac tumors. This case report describes a rare case of PCL with rapid disease progression. A 51-year-old female presented with 6 months of dyspnea. Her transthoracic echocardiogram showed a large exudative circumferential pericardial effusion and bi-atrial masses. An endovascular tissue biopsy using intra-cardiac echocardiography guidance enabled the diagnosis of diffuse large B-cell lymphoma. Staging computed tomography staged the disease at Ann Arbor stage IV E. She achieved a complete response to rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisolone chemoimmunotherapy.
Anesthesia guidelines for COVID-19 patients: a narrative review and appraisal
Ong Sharon,Lim Wan Yen,Ong John,Kam Peter 대한마취통증의학회 2020 Korean Journal of Anesthesiology Vol.73 No.6
The coronavirus disease 2019 (COVID-19) pandemic has challenged health systems globally and prompted the publication of several guidelines. The experiences of our international colleagues should be utilized to protect patients and healthcare workers. The primary aim of this article is to appraise national guidelines for the perioperative anesthetic management of patients with COVID-19 so that they can be enhanced for the management of any resurgence of the epidemic. PubMed and EMBASE databases were systematically searched for guidelines related to SARS-CoV and SARS-CoV-2. Additionally, the World Federation Society of Anesthesiologists COVID-19 resource webpage was searched for national guidelines; the search was expanded to include countries with a high incidence of SARS-CoV. The guidelines were evaluated using the Appraisal of Guidelines for Research and Evaluation II tool. Guidelines from Australia, Canada, China, India, Italy, South Africa, South Korea, Taiwan, the United Kingdom, and the United States of America were evaluated. All the guidelines focused predominantly on intubation and infection control. The scope and purpose of guidelines from China were the most comprehensive. The UK and South Africa provided the best clarity. Editorial independence, the rigor of development, and applicability scored poorly. Heterogeneity and gaps pertaining to preoperative screening, anesthesia technique, subspecialty anesthesia, and the lack of auditing of guidelines were identified. Evidence supporting the recommendations was weak. Early guidelines for the anesthetic management of COVID-19 patients lacked quality and a robust reporting framework. As new evidence emerges, national guidelines should be updated to enhance rigor, clarity, and applicability.

Background: Approximately 45-50% of Hepatitis C virus (HCV) infections in South Korea and Taiwan are genotype (GT) 1b. Previous phase 3 studies demonstrated that the direct-acting antiviral (DAA) regimen of ombitasvir (OBV), ritonavir-boosted paritaprevir (PTV/r; identified by Abbvie and Enanta) and dasabuvir (DSV) was well tolerated and achieved sustained virologic response at post-treatment week 12 (SVR12) in 99% of treatment-naive and 100% of treatment- experienced patients with HCV GT1b. ONYX-I (NCT02517515) was designed to evaluate efficacy and safety in Asian patients with HCV GT1b infection without cirrhosis. Methods: Treatment-naive and IFN-based therapy-experienced patients with HCV GT1b infection in South Korea, Taiwan, and China were randomized 1:1 to receive either OBV/PTV/r (25 mg/150 mg/100 mg once daily) and DSV (250 mg twice daily) or placebo for 12 weeks during the double-blind (DB) period. Patients in the placebo arm subsequently received OBV/PTV/r + DSV for 12 weeks during the open-label period. Patients will be followed for 48 weeks after last dose of study drugs. The primary objectives are to compare the SVR12 rates for the treatment-naive and -experienced patients to corresponding historical SVR rates of telaprevir + peg-interferon and ribavirin therapy, and assess the safety of the OBV/PTV/r + DSV regimen. Presented are results from the South Korean and Taiwanese populations. Results: In both South Korea and Taiwan, 120 patients were randomized and treated. Of South Korean patients, 45% were male, 33% were treatment-experienced and 89% had F0-F1 fibrosis. Of Taiwanese patients, 39% were male, 33% were treatment-experienced, and 87% had F0-F1 fibrosis. Safety data and SVR at post-treatment week 4 will be presented. Conclusions: The ONYX-I study is evaluating the safety and efficacy of DAA regimen, OBV/PTV/r + DSV, in Southeast Asian patients without cirrhosis infected with HCV GT1b. Resultant data may help inform treatment guidelines for HCV GT1b in this population.
Female Breast Cancer Incidence Among Asian and Western Populations: More Similar Than Expected
Sung, Hyuna,Rosenberg, Philip S.,Chen, Wan-Qing,Hartman, Mikael,Lim, Wei-yen,Chia, Kee Seng,Wai-Kong Mang, Oscar,Chiang, Chun-Ju,Kang, Daehee,Ngan, Roger Kai-Cheong,Tse, Lap Ah,Anderson, William F.,Ya U.S. Dept. of Health, Education, and Welfare, Publ 2015 Journal of the National Cancer Institute Vol.107 No.7
<P><B>Background:</B></P><P>Previous reports suggested that female breast cancer is associated with earlier ages at onset among Asian than Western populations. However, most studies utilized cross-sectional analyses that may be confounded by calendar-period and/or birth cohort effects. We, therefore, considered a longitudinal (forward-looking) approach adjusted for calendar-period changes and conditioned upon birth cohort.</P><P><B>Methods:</B></P><P>Invasive female breast cancer data (1988–2009) were obtained from cancer registries in China, Hong Kong, South Korea, Taiwan, Singapore, and the United States. Age-period-cohort models were used to extrapolate longitudinal age-specific incidence rates for the 1920, 1944, and 1970 birth cohorts.</P><P><B>Results:</B></P><P>Cross-sectional age-specific incidence rates rose continuously until age 80 years among US white women, but plateaued or decreased after age 50 years among Asian women. In contrast, longitudinal age-specific rates were proportional (similar) among all Asian countries and the United States with incidence rates rising continuously until age 80 years. The extrapolated estimates for the most recent cohorts in some Asian countries actually showed later ages at onset than in the United States. Additionally, over successive birth cohorts, the incidence rate ratios (IRRs) for the longitudinal curves converged (narrowed) between Asian and US white women.</P><P><B>Conclusions:</B></P><P>Similar longitudinal age-specific incidence rates along with converging IRRs indicate that the age effects for invasive breast cancer are more similar among Asian and Western populations than might be expected from a solely cross-sectional analysis. Indeed, the Asian breast cancer rates in recent generations are even surpassing the historically high rates in the United States, highlighting an urgent need for efficient prevention and treatment strategies among Asian populations.</P>
