Reference ranges of handgrip strength from 125,462 healthy adults in 21 countries: a prospective urban rural epidemiologic (PURE) study.

Abstract: Background The measurement of handgrip strength (HGS) has prognostic value with respect to all-cause mortality, cardiovascular mortality and cardiovascular disease, and is an important part of the evaluation of frailty. Published reference ranges for HGS are mostly derived from Caucasian populations in high-income countries. There is a paucity of information on normative HGS values in non-Caucasian populations from low- or middle-income countries. The objective of this study was to develop reference HGS ranges for healthy adults from a broad range of ethnicities and socioeconomically diverse geographic regions. Methods HGS was measured using a Jamar dynamometer in 125,462 healthy adults aged 35-70 years from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study. Results HGS values differed among individuals from different geographic regions. HGS values were highest among those from Europe/North America, lowest among those from South Asia, South East Asia and Africa, and intermediate among those from China, South America, and the Middle East. Reference ranges stratified by geographic region, age, and sex are presented. These ranges varied from a median (25th–75th percentile) 50 kg (43–56 kg) in men 60 years from South East Asia. Reference ranges by ethnicity and body-mass index are also reported. Conclusions Individual HGS measurements should be interpreted using region/ethnic-specific reference ranges.

Causes of Cervical Cancer in the Philippines: a Case-Control Study

Abstract: Background Among the numerous human papillomavirus (HPV) types, only types 16 and 18 have been formally classified as human carcinogens. To evaluate the associations of 33 HPV types and other risk factors with squamous cell carcinoma and adenocarcinoma of the cervix, we performed a hospital-based, case-control study in the Philippines. Methods The study included 356 case subjects who had histologically confirmed cervical cancer (323 incident cases of squamous cell carcinoma and 33 incident cases of adenocarcinoma/adenosquamous carcinoma) and 381 control subjects. Information on risk factors was obtained by personal interview. HPV DNA was detected in exfoliated cervical cells and biopsy specimens by use of a polymerase chain reaction assay. Results HPV DNA was detected in 93.8% of case subjects with squamous cell carcinoma and in 90.9% of case subjects with adenocarcinoma/adenosquamous carcinoma compared with 9.2% of control subjects, giving age-adjusted odds ratios of 156 (95% confidence interval [CI] = 87-280) for squamous cell carcinoma and 111 (95% CI = 31-392) for adenocarcinoma/adenosquamous carcinoma. Fifteen different HPV types were detected in squamous cell carcinoma, and six different HPV types were detected in adenocarcinoma/adenosquamous carcinoma. Among HPV types other than types 16 and 18, the associations of HPV with risk of squamous cell carcinoma were strongest for HPV45. In addition to HPV, high parity, low socioeconomic status, and smoking were also associated with both types of cervical cancer. Conclusions As has been shown for squamous cell carcinoma, HPV is the central cause of adenocarcinoma/adenosquamous carcinoma of the uterine cervix. The observed associations of less prevalent HPV types with cervical cancer have important implications for cervical cancer prevention strategies.

The Global State of the Genetic Counseling Profession.

Abstract: The profession of genetic counseling (also called genetic counselling in many countries) began nearly 50 years ago in the United States, and has grown internationally in the past 30 years. While there have been many papers describing the profession of genetic counseling in individual countries or regions, data remains incomplete and has been published in diverse journals with limited access. As a result of the 2016 Transnational Alliance of Genetic Counseling (TAGC) conference in Barcelona, Spain, and the 2017 World Congress of Genetic Counselling in the UK, we endeavor to describe as fully as possible the global state of genetic counseling as a profession. We estimate that in 2018 there are nearly 7000 genetic counselors with the profession established or developing in no less than 28 countries.

Outcome of screening by clinical examination of the breast in a trial in the Philippines

Abstract: The value of screening by Clinical Examination of the Breast (CBE) as a means of reducing mortality from breast cancer (BC) is not established. The issue is relevant, as CBE may be a suitable option for countries in economic transition, where incidence rates are on the increase but limited resources do not permit screening by mammography. Our aims were to assess whether mass screening by CBE carried out by trained para-medical personnel is feasible in an urban population of a low-income country, and its efficacy in reducing BC mortality. Our study was designed as a randomised controlled trial of the effect on BC mortality of 5 annual CBE carried out by trained nurses. The target population was women aged 35-64 years, resident in 12 municipalities of the National Capital Region of Manila, Philippines. The units of randomization were the 202 health centres (HC) within the selected municipalities. During 1995 nurses and midwives were recruited and trained in performing CBE. The first round of screening took place in 1996-1997. The intervention however showed a refractory attitude of the population with respect to clinical follow-up and was discontinued after the completion of the first screening round. Cases of breast cancer occurring in the study population during 1996-1999 were identified by the 2 local population-based registries. In the single screening round 151,168 women were interviewed and offered CBE, 92% accepted (138,392), 3,479 were detected positive for a lump and referred for diagnosis. Of these only 1220 women (35%) completed diagnostic follow-up, whereas 42.4% actively refused further investigation even with home visits, and 22.5% were not traced. Of 53 cases that occurred among screen-positive women in the 2 years after CBE only 34 were diagnosed through the intervention. Eighty cases occurred among screen-negative women. The test sensitivity for CBE repeated annually was 53.2%. The actual sensitivity of the programme was 25.6% and positive predictive value 1%. Screen-detected cases were non-significantly less advanced than the others. Previous studies have shown that most breast cancer cases in the Philippines present at advanced stages and have an unfavourable outcome. Although CBE undertaken by health workers seems to offer a cost-effective approach to reducing mortality, the sensitivity of the screening programme in the real context was low. Moreover, in this relatively well-educated population, cultural and logistic barriers to seeking diagnosis and treatment persist and need to be addressed before any screening programme is introduced.
