BACKGROUND |
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia and associated with long term macrovascular and microvascular complications. Platelet parameters such as mean platelet volume and platelet count are indicators of thrombotic potential. These parameters have been reported to be increased in... |
METHODS |
A hospital based cross-sectional observational study was conducted at KIST Medical College Teaching Hospital from February to May 2018. A total of 300 participants were included in the study which were grouped into Group 1,2 and 3 based on fasting blood glucose level as non -diabetic controls, impaired fasting glucose ... |
RESULTS |
Mean platelet volume was significantly higher in diabetic and impaired fasting glucose group (7.40 ± 0.77 fl and 6.62 ± 0.58 fl), respectively as compared to non diabetic group (6.06 ± 0.41 fl) (p<0.001). There was no significant difference in the platelet count between the three groups (p=0.869). Significant correlati... |
CONCLUSIONS |
Mean platelet volume is increased in patients with type 2 diabetes mellitus and impaired fasting glucose. This is a simple and cost effective test to predict vascular complications in type 2 diabetes mellitus.Nongeneric J-holomorphic curves in symplectic 4-manifolds |
This note discusses the structure of J-holomorphic curves in symplectic 4-manifolds (M,\om) when J\in \Jj(\Ss), the set of \om-tame J for which a fixed chain \Ss of transversally intersecting embedded spheres of self-intersection \le -2 is J-holomorphic. Extending work by Biran (in Invent. Math. (1999)), it shows that ... |

OBJECTIVE |
The Health Resources and Services Administration's Bureau of Health Professions developed a demographic utilization-based model of physician specialty requirements to explore the consequences of a broad range of scenarios pertaining to the nation's health care delivery system on need for physicians. |
DATA SOURCE/STUDY SETTING |
The model uses selected data primarily from the National Center for Health Statistics, the American Medical Association, and the U.S. Bureau of Census. Forecasts are national estimates. |
STUDY DESIGN |
Current (1989) utilization rates for ambulatory and inpatient medical specialty services were obtained for the population according to age, gender, race/ethnicity, and insurance status. These rates are used to estimate specialty-specific total service utilization expressed in patient care minutes for future populations... |
DATA COLLECTION/EXTRACTION METHODS |
Secondary data were analyzed and put into matrixes for use in the mainframe computer-based model. Several missing data points, e.g., for HMO-enrolled populations, were extrapolated from available data by the project's contractor. |
PRINCIPAL FINDINGS |
The authors contend that the Bureau's demographic utilization model represents improvements over other data-driven methodologies that rely on staffing ratios and similar supply-determined bases for estimating requirements. The model's distinct utility rests in offering national-level physician specialty requirements fo... |

BACKGROUND |
In the absence of a vaccine or effective treatment for COVID-19, countries have adopted nonpharmaceutical interventions (NPIs) such as social distancing and full lockdown. An objective and quantitative means of passively monitoring the impact and response of these interventions at a local level is needed. |
OBJECTIVE |
We aim to explore the utility of the recently developed open-source mobile health platform Remote Assessment of Disease and Relapse (RADAR)–base as a toolbox to rapidly test the effect and response to NPIs intended to limit the spread of COVID-19. |
METHODS |
We analyzed data extracted from smartphone and wearable devices, and managed by the RADAR-base from 1062 participants recruited in Italy, Spain, Denmark, the United Kingdom, and the Netherlands. We derived nine features on a daily basis including time spent at home, maximum distance travelled from home, the maximum nu... |
RESULTS |
We were able to quantify expected changes in time spent at home, distance travelled, and the number of nearby Bluetooth-enabled devices between prelockdown and during lockdown periods (P<.001 for all five countries). We saw reduced sociality as measured through mobility features and increased virtual sociality through... |
CONCLUSIONS |
RADAR-base, a freely deployable data collection platform leveraging data from wearables and mobile technologies, can be used to rapidly quantify and provide a holistic view of behavioral changes in response to public health interventions as a result of infectious outbreaks such as COVID-19. RADAR-base may be a viable ... |

A 45-year-old woman with a local recurrence on her left chest wall discharged massive exudates. At every gauze exchange, blood was still oozing out. After using Mohs paste twice, the surface had been fixed chemically and dried up, so she did not have to exchange gauze, and there was no more bleeding. A 55-year-old woma... |
Most experts in public health have condemned the NHS reforms, saying they could make it harder to reduce health inequalities and to respond to emergencies. |
A survey of almost 1000 public health specialist members of the UK Faculty of Public Health—the standard setting body for these clinicians—found little support for the reforms. |
The faculty surveyed its members on the reforms contained in the Health and Social Care Bill, which is currently being scrutinised by the House of Lords as it progresses through parliament on its way to becoming law next year. |
