An interactive course to enhance self-efficacy of family practitioners to treat obesity

Background  

Physicians' awareness of their important role in defusing the obesity epidemic has increased. However, the number of family practitioners who treat obesity problems continues to be low. Self-efficacy refers to the belief in one's ability to organize and execute the courses of action required to produce given attainments. Thus, practitioners who judge themselves incapable of managing obesity do not even try. We hypothesized that practitioners' self-efficacy and motivation would be enhanced as a result of participating in an interactive course designed to enrich their knowledge of obesity management.     

Obstructive Sleep Apnea and Cardiovascular Comorbidities: A Large Epidemiologic Study

Obstructive sleep apnea (OSA) is a common disorder, characterized by cyclic cessation of airflow for 10 seconds or more. There is growing awareness that OSA is related to the development and progression of cardiovascular disease. However, only a few studies have associated OSA directly to major cardiovascular events. The aim of this study was to evaluate the relationship between OSA and cardiovascular morbidity in a well defined population of patients.The electronic database of the central district of a major health management organization was searched for all patients diagnosed with OSA in 2002–2010. For each patient identified, an age- and sex-matched patient was randomly selected from the members of the same health management organization who did not have OSA. Data on demographics, socioeconomic status, and relevant medical parameters were collected as well.The study population included 2797 patients, average age 58.1, in which 76.6% were males. There was a significant correlation between OSA and the presence of ischemic heart disease (P < 0.001), pulmonary hypertension (P < 0.001), congestive heart failure (P < 0.001), cardiomyopathy (P = 0.003), and arrhythmia (P < 0.001). OSA was also significantly correlated with low socioeconomic status (P < 0.001).OSA and cardiovascular disease were strongly correlated. As such, early diagnosis and treatment of OSA may change the course of both diseases. We suggest that sleep disordered breathing should be routinely assessed in patients with cardiovascular problems. An ear–nose–throat evaluation may also be important to rule out anatomic disorders that cause upper airway obstruction.     

Patient and family physician preferences for care and communication in the eventuality of anthrax terrorism

BACKGROUND: The threat of bioterrorism consequent to the September 11, 2001 attack in the USA generated suggestions for improved medical response mainly through hospital preparedness. OBJECTIVES: The aim of the present study was to investigate the impact of this period of tension on patients' first choice for care and for receiving relevant information, and on primary care doctors' feelings of responsibility in the eventuality of an anthrax attack. METHODS: During October 11-31, 2001, 500 patients from 30 clinics throughout Israel were asked to complete a questionnaire on their awareness of the anthrax threat, measures taken to prepare for it, and preferred sources of care and information. Their 30 physicians, and an additional 20, completed a questionnaire on knowledge about anthrax and anthrax-related patient behaviours and clinic visits. RESULTS: The outstanding finding was the low rate (30%) of patients who chose the hospital emergency department as their first choice for care or information if they were worried about an anthrax attack or the media communicated that an attack was in progress. The other two-thirds preferred their family doctor or the health authorities. Most of the physicians (89%) felt it was their responsibility to treat anthrax-infected patients and that they should therefore be supplied with appropriate guidelines. CONCLUSION: This study suggests that in Israel, a country with a high degree of awareness of civil defence aspects, both patients and primary care doctors believe that family physicians should have a major role in the case of bioterrorist attacks. This must be seriously considered during formulation of relevant health services programmes.     

Dry eye in diabetic patients

PURPOSE: To compare the prevalence of keratoconjunctivitis sicca (KCS) in a prospective cohort of 22,382 diabetic patients with that in the general population. DESIGN: Prospective, observational, cohort study. METHODS: Setting: A district of israel's largest health maintenance organization. STUDY POPULATION: We followed the electronic medical records of all patients in the district older than 50 years (159,634 patients) between January 1 and December 31, 2003. Of those, 22,382 (14.0%) had diabetes. OBSERVATION PROCEDURE: The proportion of ocular lubrication consumers was compared among diabetic and nondiabetic patients. All HbA1c laboratory tests performed by the diabetic patients were documented (41,910 tests), and glycemic control was correlated with the consumption of ocular lubrication. MAIN OUTCOME MEASURES: Ocular lubrication use by diabetic patients compared with the general population and the relationship between glycemic control and ocular lubrication use. RESULTS: After age and gender adjustment, a significantly higher percentage of diabetic patients (20.6%) received ocular lubrication, compared with nondiabetic patients (13.8%, P < .001). The difference was significant for all age groups and for both sexes (P < .001). A similar significant difference was prominent between diabetic and nondiabetic patients aged 60 to 89 years who were frequent users of ocular lubrication. Ocular lubrication consumption increased with poorer glycemic control (mean annual HbA1c levels). Multivariate analysis revealed this effect to be independent of age, sex, place of birth, or place of residence. CONCLUSIONS: KCS is significantly more common among diabetic patients. Poor glycemic control correlates with increased artificial tear use in diabetic patients.     

The association of keratoconus with blepharitis

Background

Identifying potentially treatable risk factors for the progression of keratoconus is of great importance. The purpose of this study was to determine the association between blepharitis and keratoconus.

Methods

In this prospective, comparative, observational study, 50 keratoconus participants from the central district of the Clalit Health Services Health Maintenance Organization in Israel underwent comprehensive eye examination. Seventy‐two healthy medical personnel of similar ages were randomly chosen as a control group. The signs and symptoms of blepharitis in each participant were assessed. A thorough survey of the eyelids (scales and foam on the eyelashes, missing eyelashes and expression of meibomian gland contents) was performed. All participants were required to complete two questionnaires: the Ocular Surface Disease Index questionnaire and a questionnaire regarding symptoms, signs and risk factors for blepharitis.

Results

Blepharitis was more common in keratoconus participants than in the control group (24 per cent versus 2.8 per cent, p < 0.001). A higher proportion of keratoconus participants reported rubbing their eyes more than once a day (36 per cent versus 11.1 per cent, p = 0.002) as well as red and tired eyes (12 per cent versus zero per cent, p = 0.009). On external eye examination, signs of blepharitis and meibomian gland dysfunction were found more frequently in the keratoconus group (p < 0.05).

Conclusions

Signs and symptoms of blepharitis occur more often in keratoconus participants than in healthy individuals. Blepharitis‐related inflammation and associated eye rubbing may contribute to disease progression.

     

The advanced-DiaRem score improves prediction of diabetes remission 1 year post-Roux-en-Y gastric bypass

Aims/hypothesis

Not all people with type 2 diabetes who undergo bariatric surgery achieve diabetes remission. Thus it is critical to develop methods for predicting outcomes that are applicable for clinical practice. The DiaRem score is relevant for predicting diabetes remission post-Roux-en-Y gastric bypass (RYGB), but it is not accurate for all individuals across the entire spectrum of scores. We aimed to develop an improved scoring system for predicting diabetes remission following RYGB (the Advanced-DiaRem [Ad-DiaRem]).

Methods

We used a retrospective French cohort (n = 1866) that included 352 individuals with type 2 diabetes followed for 1 year post-RYGB. We developed the Ad-DiaRem in a test cohort (n = 213) and examined its accuracy in independent cohorts from France (n = 134) and Israel (n = 99).

Results

Adding two clinical variables (diabetes duration and number of glucose-lowering agents) to the original DiaRem and modifying the penalties for each category led to improved predictive performance for Ad-DiaRem. Ad-DiaRem displayed improved area under the receiver operating characteristic curve and predictive accuracy compared with DiaRem (0.911 vs 0.856 and 0.841 vs 0.789, respectively; p = 0.03); thus correcting classification for 8% of those initially misclassified with DiaRem. With Ad-DiaRem, there were also fewer misclassifications of individuals with mid-range scores. This improved predictive performance was confirmed in independent cohorts.

Conclusions/interpretation

We propose the Ad-DiaRem, which includes two additional clinical variables, as an optimised tool with improved accuracy to predict diabetes remission 1 year post-RYGB. This tool might be helpful for personalised management of individuals with diabetes when considering bariatric surgery in routine care, ultimately contributing to precision medicine.
