In attempts to improve patient safety, the World Health Organization (WHO) developed a checklist to be used at critical perioperative moments. This meta-analysis examines the impact of the WHO surgical safety checklist (SSC) on various patient outcomes. Methods: A comprehensive search of all published studies assessing the use of the WHO SSC in patients undergoing surgery was conducted. Studies using the WHO SSC in any surgical setting, with pre-implementation and post-implementation outcome data were included. The incidence of patient outcomes (total complications, surgical site infections, unplanned return to the operating room (OR) within 30 days, and overall mortality) and adherence to safety measures were analyzed. Results: 10 studies involving 51,125 patients (27,490 prior to implementation and 23,635 after implementation of the WHO SSC) were analyzed. The implementation of the WHO SSC significantly reduced the risk of total complications by 37.9%, surgical site infections by 45.5%, unplanned return to OR by 32.1%, and mortality by 15.3%. Increased adherence to safety measures including airway evaluation, use of pulse oximetry, prophylactic antibiotics when necessary, confirmation of patient name and surgical site, and sponge count was also observed. Conclusions: The use of the WHO SSC is associated with a significant reduction in post-operative complication rates and mortality. The WHO SSC is a valuable tool that should be universally implemented in all surgical centers and utilized in all surgical patients.展开更多

Semen analysis results （volume, sperm count, motility, and morphology） were the primary outcomes. An electronic search to collect the data was conducted using the Medline/PubMed, SJU discover, and Google Scholar databases. We searched articles published from 2010 to August 2015, i.e., after the publication of the 2010 WHO manual. We included only those studies that reported the actual semen parameters of adult infertile men diagnosed with clinical varicocele and contained a control group of either fertile men or normozoospermic men who were not diagnosed with varicocele. Ten studies were included in the meta-analysis, involving 1232 men. Varicocele was associated with reduced sperm count （mean difference： -44.48 x 106 ml-1; 95% Ch -61.45, -27.51 x 106 ml-1; P〈 0.001）, motility （mean difference： -26.67%; 95% Ch -34.27, -19.08; P 〈 0.001）, and morphology （mean difference： -19.68%; 95% Ch -29.28, -10.07; P 〈 0.001） but not semen volume （mean difference： -0.23 ml; 95% CI： -0.64, 0.17）. Subgroup analyses indicated that the magnitude of effect was influenced by control subtype but not WHO laboratory manual edition used for semen assessment. We conclude that varicocele is a significant risk factor that negatively affects semen quality, but the observed pooled effect size on semen parameters does not seem to be affected by the WHO laboratory manual edition. Given most of the studies published after 2010 still utilized the 1999 manual for semen analysis, further research is required to fully understand the clinical implication of the 2010 WHO laboratory manual on the association between varicocele and semen parameters.展开更多

The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality. RESULTS The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions(0.64 vs 0.80, respectively). Among six continents, Oceania had the lowest(0.60) and Africa had the highest(0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs(P = 0.001 and P = 0.001, respectively).CONCLUSION The MIR variation for gastric cancer would predict regional health disparities.展开更多

In considering the needs and demands of male reproductive health research in Asia and the Pacific, the followingsix research topics are recommended as the priority research areas: male contraceptive technology; male reproductivehealth behaviour and male adolescent reproductive health; male reproductive aging including male menopause and otherdiseases; male RTIs, STDs, HIV/AIDS; prevalence, management and prevention of male infertility; environment andsemen quality and other male reproductive problems. One of the major challenges now facing us is the elaboration of a comprehensive, yet realistic male reproductivehealth research agenda that reflect the needs and demands of Asian developing countries. To this end, to make use of aninterdisciplinary approach is of strategic importance. The most creative insights and productive leads are likely toemerge from a research team that is interdisciplinary especially in the field of reproductive health.展开更多

Hepatitis B vaccines became commercially available in the 1980 s. The World Health Organization recommended the integration of the HB vaccine into the national immunisation programs in all countries. HBV prevention strategies are classified into three groups:(1) universal vaccination alone;(2) universal vaccination with screening of pregnant women plus HB immune globulin(HBIG) at birth; and(3) selective vaccination with screening of pregnant women plus HBIG at birth. Most low-income countries have adopted universal vaccine programs without screening of pregnant women. However, HB vaccines are not widely used in low-income countries. The Global Alliance for Vaccine and Immunization was launched in 2000, and by 2012, the global coverage of a three-dose HB vaccine had increased to 79%. The next challenges are to further increase the coverage rate, close the gap between recommendations and routine practices, approach highrisk individuals, screen and treat chronically infected individuals, and prevent breakthrough infections. To eradicate HBV infections, strenuous efforts are required to overcome socioeconomic barriers to the HB vaccine; this task is expected to take several decades to complete.展开更多

Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTSIll defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors (P < 0.001); this feature had high specificity in the identification of G2-3 and stage III-IV tumors (90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage III-IV lesions compared to well differentiated and low-stage tumors (1.09 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.45 × 10<sup>-3</sup> mm<sup>2</sup>/s and 1.10 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.53 × 10<sup>-3</sup> mm<sup>2</sup>/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cut-offs of 1.21 and 1.28 × 10<sup>-3</sup> mm<sup>2</sup>/s for the identification of G2-3 and stage III-IV tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64% (95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSIONMR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.展开更多

Many studies have investigated the correlation between the pathohistological characteristics in gastric cancer and patient characteristics, disease specific criteria and overall outcome. It is still controversial as to which classification system imparts the most reliable information, and therefore, the choice of system may vary in clinical routine. In addition to the most common classification systems, such as the Laurén and the World Health Organization (WHO) classifications, other authors have tried to characterize and classify gastric cancer based on the microscopic morphology and in reference to the clinical outcome of the patients. In more than 50 years of systematic classification of the pathohistological characteristics of gastric cancer, there is no sole classification system that is consistently used worldwide in diagnostics and research. However, several national guidelines for the treatment of gastric cancer refer to the Laurén or the WHO classifications regarding therapeutic decision-making, which underlines the importance of a reliable classification system for gastric cancer. The latest results from gastric cancer studies indicate that it might be useful to integrate DNA- and RNA-based features of gastric cancer into the classification systems to establish prognostic relevance. This article reviews the diagnostic relevance and the prognostic value of different pathohistological classification systems in gastric cancer.展开更多

HRQOL in HCC patients is multifaceted and affected by medical factor which encompasses HCC and its complications, oncological and palliative treatment for HCC, underlying liver disease, as well as the psychological, social or spiritual reaction to the disease. Many patients presented late with advanced disease and limited survival, plagued with multiple symptoms, rendering QOL a very important aspect in their general well being. Various instruments have been developed and validated to measure and report HRQOL in HCC patients, these included general HRQOL instruments, e.g., Short form(SF)-36, SF-12, Euro Qo L-5D, World Health Organization Quality of Life Assessment 100(WHOQOL-100), World Health Organization Quality of Life Assessment abbreviated version; general cancer HRQOL instruments, e.g., the European Organisation for Research and Treatment of Cancer(EORTC) QLQ-C30, Functional Assessment of Cancer Therapy(FACT)-General, Spitzer Quality of Life Index; and liver-cancer specific HRQOL instruments, e.g., EORTC QLQ-HCC18, FACT-Hepatobiliary(FACT-Hep), FACT-Hep Symptom Index, Trial Outcome Index. Important utilization of HRQOL in HCC patients included description of symptomatology and HRQOL of patients, treatment endpoint in clinical trial, prognostication of survival, benchmarking of palliative care service and health care valuation. In this review, difficulties regarding the use of HRQOL data in research and clinical practice, including choosing a suitable instrument, problems of missing data, data interpretation, analysis and presentation are examined. Potential solutions are also discussed.展开更多

A survey requesting information about methods of semen analysis was distributed to employees of 55 laboratories. Respondents who had participated in external seminological workshops （31%） were termed certified respondents （CR）, the remaining （69%）--non-certified respondents （NCR）. Only one laboratory （6%） in the CR group and none in the NCR were compliant with WHO guidelines for methods and equipment used to evaluate seminal volume, sperm motility, concentration, vitality and morphology. Most problems were of volume measurement （weighing method was reported by 17% of CR and 10% of NCR） and staining method for sperm morphology （Papanicolau or Diff-Quik were found in 33% of CR and 23% of NCR）. A three- or four-point grading of sperm motility was used by the majority of respondents; however, 17% of CR and 37% of NCR did not use a laboratory counter to tally spermatozoa. Although a haemocytometer method was used by 80% of laboratories in each group, the improved Neubauer chamber was used only by 42% of CR and 19% of NCR. In each group, 24% of laboratories did not perform a vitality test. Procedural errors and the interchangeable utilization of two or even three methods to analyse a given parameter was observed in both groups. The results indicate a need for standardisation of the methods and continuous, unified training in semen analysis in Polish laboratories.展开更多

They also underwent verum acupuncture or electroacupuncture at Baihui （GV20） and Yintang （GV29）. The World Health Organization Quality of Life Scale Brief Version showed a significant increase in the total scores of patients who underwent verum acupuncture and electroacupuncture for 6 weeks compared with those who were given paroxetine only; significantly increased physical domain and social relationship scores in verum acupuncture patients compared with paroxetine only; and significantly elevated psychological domain scores with electroacupuncture compared with paroxetine only. These results indicate that both verum acupuncture and electroacupuncture can improve quality of life in depressed patients undergoing paroxetine treatment,展开更多

文摘AIM To evaluate the association between mortality-to-incidence ratios(MIRs) and health disparities.METHODS In this study, we used the GLOBOCAN 2012 database to obtain the cancer incidence and mortality data for 57 countries, and combined this information with the World Health Organization(WHO) rankings and total expenditures on health/gross domestic product(e/GDP). The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality. RESULTS The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions(0.64 vs 0.80, respectively). Among six continents, Oceania had the lowest(0.60) and Africa had the highest(0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs(P = 0.001 and P = 0.001, respectively).CONCLUSION The MIR variation for gastric cancer would predict regional health disparities.
文摘Research that addresses male reproductive health should assist in the development of reproductive healthprogrammes and policy; identify and test new leads in male contraceptive technology; establish effective maleinvolvement initiatives which are likely to have a positive impact on the reproductive health of men and women; guidethe allocation of health care resources to ensure cost-effectiveness of interventions; generate new knowledge, developdiagnostic technology in reproductive health and offer optimal treatment/care regimens. In considering the needs and demands of male reproductive health research in Asia and the Pacific, the followingsix research topics are recommended as the priority research areas: male contraceptive technology; male reproductivehealth behaviour and male adolescent reproductive health; male reproductive aging including male menopause and otherdiseases; male RTIs, STDs, HIV/AIDS; prevalence, management and prevention of male infertility; environment andsemen quality and other male reproductive problems. One of the major challenges now facing us is the elaboration of a comprehensive, yet realistic male reproductivehealth research agenda that reflect the needs and demands of Asian developing countries. To this end, to make use of aninterdisciplinary approach is of strategic importance. The most creative insights and productive leads are likely toemerge from a research team that is interdisciplinary especially in the field of reproductive health.
文摘In December,2019,pneumonia triggered by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)surfaced in Wuhan,China.An acute respiratory illness named coronavirus disease 2019(COVID-19)is caused by a new coronavirus designated as SARS-CoV-2.COVID-19 has surfaced as a major pandemic in the 21st century as yet.The entire world has been affected by this virus.World Health Organization proclaimed COVID-19 pandemic as a public health emergency of international concern on January 30,2020.SARS-CoV-2 shares the same genome as coronavirus seen in bats.Therefore,bats might be its natural host of this virus.It primarily disseminates by means of the respiratory passage.Evidence revealed human-to-human transmission.Fever,cough,tiredness,and gastrointestinal illness are the manifestations in COVID-19-infected persons.Senior citizens are more vulnerable to infections which can lead to dangerous consequences.Various treatment strategies including antiviral therapies are accessible for the handling of this disease.In this review,we organized the most recent findings on COVID-19 history,origin,transmission,genome structure,replication,epidemiology,pathogenesis,clinical features,diagnosis,and treatment strategies.

文摘Hepatitis B(HB) virus(HBV) infection, which causes liver cirrhosis and hepatocellular carcinoma, is endemic worldwide. Hepatitis B vaccines became commercially available in the 1980 s. The World Health Organization recommended the integration of the HB vaccine into the national immunisation programs in all countries. HBV prevention strategies are classified into three groups:(1) universal vaccination alone;(2) universal vaccination with screening of pregnant women plus HB immune globulin(HBIG) at birth; and(3) selective vaccination with screening of pregnant women plus HBIG at birth. Most low-income countries have adopted universal vaccine programs without screening of pregnant women. However, HB vaccines are not widely used in low-income countries. The Global Alliance for Vaccine and Immunization was launched in 2000, and by 2012, the global coverage of a three-dose HB vaccine had increased to 79%. The next challenges are to further increase the coverage rate, close the gap between recommendations and routine practices, approach highrisk individuals, screen and treat chronically infected individuals, and prevent breakthrough infections. To eradicate HBV infections, strenuous efforts are required to overcome socioeconomic barriers to the HB vaccine; this task is expected to take several decades to complete.
文摘AIMTo describe magnetic resonance (MR) imaging features of pancreatic neuroendocrine neoplasms (PanNENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and to determine the accuracy of MR imaging features in predicting their biological behavior.METHODSThis study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTSIll defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors (P < 0.001); this feature had high specificity in the identification of G2-3 and stage III-IV tumors (90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage III-IV lesions compared to well differentiated and low-stage tumors (1.09 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.45 × 10<sup>-3</sup> mm<sup>2</sup>/s and 1.10 × 10<sup>-3</sup> mm<sup>2</sup>/s vs 1.53 × 10<sup>-3</sup> mm<sup>2</sup>/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cut-offs of 1.21 and 1.28 × 10<sup>-3</sup> mm<sup>2</sup>/s for the identification of G2-3 and stage III-IV tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64% (95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSIONMR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.
文摘Several pathohistological classification systems exist for the diagnosis of gastric cancer. Many studies have investigated the correlation between the pathohistological characteristics in gastric cancer and patient characteristics, disease specific criteria and overall outcome. It is still controversial as to which classification system imparts the most reliable information, and therefore, the choice of system may vary in clinical routine. In addition to the most common classification systems, such as the Laurén and the World Health Organization (WHO) classifications, other authors have tried to characterize and classify gastric cancer based on the microscopic morphology and in reference to the clinical outcome of the patients. In more than 50 years of systematic classification of the pathohistological characteristics of gastric cancer, there is no sole classification system that is consistently used worldwide in diagnostics and research. However, several national guidelines for the treatment of gastric cancer refer to the Laurén or the WHO classifications regarding therapeutic decision-making, which underlines the importance of a reliable classification system for gastric cancer. The latest results from gastric cancer studies indicate that it might be useful to integrate DNA- and RNA-based features of gastric cancer into the classification systems to establish prognostic relevance. This article reviews the diagnostic relevance and the prognostic value of different pathohistological classification systems in gastric cancer.
文摘Health related quality of life(HRQOL) is increasingly recognized as an important clinical parameter and research endpoint in patients with hepatocellular carcinoma(HCC). HRQOL in HCC patients is multifaceted and affected by medical factor which encompasses HCC and its complications, oncological and palliative treatment for HCC, underlying liver disease, as well as the psychological, social or spiritual reaction to the disease. Many patients presented late with advanced disease and limited survival, plagued with multiple symptoms, rendering QOL a very important aspect in their general well being. Various instruments have been developed and validated to measure and report HRQOL in HCC patients, these included general HRQOL instruments, e.g., Short form(SF)-36, SF-12, Euro Qo L-5D, World Health Organization Quality of Life Assessment 100(WHOQOL-100), World Health Organization Quality of Life Assessment abbreviated version; general cancer HRQOL instruments, e.g., the European Organisation for Research and Treatment of Cancer(EORTC) QLQ-C30, Functional Assessment of Cancer Therapy(FACT)-General, Spitzer Quality of Life Index; and liver-cancer specific HRQOL instruments, e.g., EORTC QLQ-HCC18, FACT-Hepatobiliary(FACT-Hep), FACT-Hep Symptom Index, Trial Outcome Index. Important utilization of HRQOL in HCC patients included description of symptomatology and HRQOL of patients, treatment endpoint in clinical trial, prognostication of survival, benchmarking of palliative care service and health care valuation. In this review, difficulties regarding the use of HRQOL data in research and clinical practice, including choosing a suitable instrument, problems of missing data, data interpretation, analysis and presentation are examined. Potential solutions are also discussed.

文摘Colorectal neuroendocrine tumors (NETs) originate from neuroendocrine cells in the intestinal tract, and represent a small area within oncology, but one which has provided increasing new data during the past years. Although the World Health Organization has determined clinical and histological features to predict prognosis for such tumors, they may not be valid on an individual basis. We aim to give an overview of the recent findings with regard to pathology, molecular genetics and diagnosis of NETs.
文摘The aim of the study was to determine the degree of compliance of Polish laboratories with World Health Organization （WHO） recommendations, with regard to semen analysis methodology. A survey requesting information about methods of semen analysis was distributed to employees of 55 laboratories. Respondents who had participated in external seminological workshops （31%） were termed certified respondents （CR）, the remaining （69%）--non-certified respondents （NCR）. Only one laboratory （6%） in the CR group and none in the NCR were compliant with WHO guidelines for methods and equipment used to evaluate seminal volume, sperm motility, concentration, vitality and morphology. Most problems were of volume measurement （weighing method was reported by 17% of CR and 10% of NCR） and staining method for sperm morphology （Papanicolau or Diff-Quik were found in 33% of CR and 23% of NCR）. A three- or four-point grading of sperm motility was used by the majority of respondents; however, 17% of CR and 37% of NCR did not use a laboratory counter to tally spermatozoa. Although a haemocytometer method was used by 80% of laboratories in each group, the improved Neubauer chamber was used only by 42% of CR and 19% of NCR. In each group, 24% of laboratories did not perform a vitality test. Procedural errors and the interchangeable utilization of two or even three methods to analyse a given parameter was observed in both groups. The results indicate a need for standardisation of the methods and continuous, unified training in semen analysis in Polish laboratories.
文摘With the increasing clinical use of cytostatic and novel biologic targeted agents,conventional morphologic tumor burden assessments,including World Health Organization criteria and Response Evaluation Criteria in Solid Tumors,are confronting limitations because of their difficulties in distinguishing viable tumor from necrotic or fibrotic tissue.Therefore,the investigation for reliable quantitative biomarkers of therapeutic response such as metabolic imaging or functional imaging has been desired.In this review,we will discuss the conventional and new approaches to assess tumor burden.Since targeted therapy or locoregional therapies can induce biological changes much earlier than morphological changes,these functional tumor burden analyses are very promising.However,some of them have not gone thorough all steps for standardization and validation.Nevertheless,these new techniques and criteria will play an important role in the cancer management,and provide each patient more tailored therapy.

文摘Depressed patients with scores of 17 or more on the 17 items of the Hamilton Depression Rating Scale were treated with the antidepressant drug paroxetine. They also underwent verum acupuncture or electroacupuncture at Baihui （GV20） and Yintang （GV29）. The World Health Organization Quality of Life Scale Brief Version showed a significant increase in the total scores of patients who underwent verum acupuncture and electroacupuncture for 6 weeks compared with those who were given paroxetine only; significantly increased physical domain and social relationship scores in verum acupuncture patients compared with paroxetine only; and significantly elevated psychological domain scores with electroacupuncture compared with paroxetine only. These results indicate that both verum acupuncture and electroacupuncture can improve quality of life in depressed patients undergoing paroxetine treatment,
文摘Gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs)are rare epithelial neoplasms derived from pluripotent endocrine cells along the gastrointestinal tract and pancreas.GEP-NENs are classified into well-differentiated neuroendocrine tumors and poorly differentiated neuroendocrine carcinomas.Despite overlapping morphological features,GEP-NENs vary in molecular biology,epigenetic,clinical behavior,treatment response,and prognosis features and remain an unmet clinical challenge.In this review,we introduce recent updates on the histopathologic classification,including the tumor grading and staging system,molecular genetics,and systemic evaluation of the diagnosis and treatment of GEP-NENs at different anatomic sites,together with some insights into the diagnosis of challenging and unusual cases.We also discuss the application of novel therapeutic approaches for GEP-NENs,including peptide receptor radionuclide therapy,targeted therapy,and immunotherapy with immune checkpoint inhibitors.These findings will help improve patient care with precise diagnosis and individualized treatment of patients with GEP-NENs.
