Digital intervention increases influenza vaccination rates for people with diabetes in a decentralized randomized trial.

People with diabetes (PWD) have an increased risk of developing influenza-related complications, including pneumonia, abnormal glycemic events, and hospitalization. Annual influenza vaccination is recommended for PWD, but vaccination rates are suboptimal. The study aimed to increase influenza vaccination rate in people with self-reported diabetes. This study was a prospective, 1:1 randomized controlled trial of a 6-month Digital Diabetes Intervention in U.S. adults with diabetes. The intervention group received monthly messages through an online health platform. The control group received no intervention. Difference in self-reported vaccination rates was tested using multivariable logistic regression controlling for demographics and comorbidities. The study was registered at clinicaltrials.gov: NCT03870997. A total of 10,429 participants reported influenza vaccination status (5158 intervention, mean age (±SD) = 46.8 (11.1), 78.5% female; 5271 control, Mean age (±SD) = 46.7 (11.2), 79.4% female). After a 6-month intervention, 64.2% of the intervention arm reported influenza vaccination, vers us 61.1% in the control arm (diff = 3.1, RR = 1.05, 95% CI [1.02, 1.08], p = 0.0013, number needed to treat = 33 to obtain 1 additional vaccination). Completion of one or more intervention messages was associated with up to an 8% increase in vaccination rate (OR 1.27, 95% CI [1.17, 1.38], p < 0.0001). The intervention improved influenza vaccination rates in PWD, suggesting that leveraging new technology to deliver knowledge and information can improve influenza vaccination rates in high-risk populations to reduce public health burden of influenza. Rapid cycle innovation could maximize the effects of these digital interventions in the future with other populations and vaccines.

Combination antihypertensive drugs: recommendations for use.

The recommendation for first-line therapy for hypertension remains a beta blocker or diuretic given in a low dosage. A target blood pressure of less than 140/90 mm Hg is achieved in about 50 percent of patients treated with monotherapy; two or more agents from different pharmacologic classes are often needed to achieve adequate blood pressure control. Single-dose combination antihypertension therapy is an important option that combines efficacy of blood pressure reduction and a low side effect profile with convenient once-daily dosing to enhance compliance. Combination antihypertensives include combined agents from the following pharmacologic classes: diuretics and potassium-sparing diuretics, beta blockers and diuretics, angiotensin-converting enzyme (ACE) inhibitors and diuretics, angiotensin-II antagonists and diuretics, and calcium channel blockers and ACE inhibitors.

Patterns and correlates of tobacco use among suburban Philadelphia 6th- through 12th-grade students.

BACKGROUND AND OBJECTIVES: Tobacco use among teenagers is increasing, even in the face of an understanding of its harmful effects. Data suggest that tobacco use often begins before entrance to eighth grade. This study examined the prevalence of tobacco use among students in 6th grade and compared it to the prevalence of tobacco use among 8th, 10th, and 12th graders in a northeastern suburban community and to national data. METHODS: We used a survey that measured selected tobacco and smokeless tobacco use, demographic variables, school-related factors, and social influences on the use of tobacco products. RESULTS: Sixth-grade tobacco use existed but was minimal compared to the rates seen in 8th, 10th, and 12th graders. Only 1% of 6th graders reported they were current smokers, compared with 41% of 12th graders. Risk factors for becoming a smoker were smoking habits of parents, siblings, and friends. CONCLUSIONS: Cigarette experimentation and use begins as early as sixth grade and increases substantially by eighth grade. Our data suggest that efforts toward primary prevention of smoking should be pursued between sixth and eighth grade.

Screening for Chlamydia trachomatis infection.

Infection with Chlamydia trachomatis can be either symptomatic or asymptomatic. In adults, complications include infertility, chronic pelvic pain and ectopic pregnancy. Complications in newborns include conjunctivitis and pneumonia. Screening of asymptomatic women at high risk for the disease can identify candidates for antibiotic therapy. Until recently, chlamydia cell culture was the only diagnostic test and it was not widely available. Because the specificity of cell culture is 100 percent, it remains the standard against which other tests are measured. The recent development of nonculture tests makes it feasible for most laboratories and physicians' offices to offer testing. The main disadvantage of nonculture tests is low specificity. A positive screening test in a woman at low risk should be confirmed by a second test. Routine screening and treatment of patients who are at high risk can decrease the incidence, complications and transmission of chlamydial infection.

Professional satisfaction and dissatisfaction of family physicians.

BACKGROUND: Physicians' satisfaction with their professional life influences the quality of patient care they provide and helps to determine the number and type of students attracted to the various fields of medicine. In this study, we sought to delineate areas of satisfaction and dissatisfaction among family physicians. METHODS: A self-administered questionnaire was sent to all physicians in the state of Pennsylvania who were included in the 1990 directory of the American Board of Family Practice (N = 1944). RESULTS: Completed questionnaires were received from 1066 family physicians in full-time practice. Sixty-five percent were satisfied with their professional lives. Patient relationships, a sense of clinical competence, and their relationships with their partners were among the most satisfying aspects of practice for all family physicians. Problems identified included regulations by third-party payers and government agencies and the large amount of paperwork encountered in practice. There were significant (P < .001) differences in satisfaction between physicians in different practice arrangements. Significant differences between practice types were also found in the degree of dissatisfaction with third-party payers and government agencies, paperwork, isolation from other physicians, and the threat of a malpractice suit. CONCLUSIONS: Almost two thirds of family physicians are satisfied with their general professional lives. Conversely, one third are not. Clear areas of satisfaction and dissatisfaction have been defined for family physicians in general as well as for family physicians in various practice environments. This information may be useful in the development of policy to structure a medical system that meets the needs of both patients and physicians.

Croup.

Viral croup is the most common form of upper airway obstruction in children 6 months to 6 years of age. It typically presents in the late fall or early winter, is often preceded by an upper respiratory infection, and is characterized by a low-grade fever, barking cough, and inspiratory stridor. Diagnosis is made on clinical grounds with no specific confirmatory test. The differential diagnosis of croup, including epiglottitis and retropharyngeal abscess, must always be considered in evaluating children with inspiratory stridor. Three therapeutic modalities are available for the treatment of croup: humidified air, racemic epinephrine, and adrenal corticosteroids. Maintaining at least 50% relative humidity in the child's room is recommended. If there is evidence of hypoxemia, a mist tent with supplemental oxygen may be helpful. Racemic epinephrine administered by nebulizer can quickly reverse airway obstruction in children with croup. The patient needs to be monitored for rebound airway obstruction for at least 2 hours after administration. The mainstay of treatment for severe croup is dexamethasone, administered 0.6 mg/kg, intramuscularly (IM). Dexamethasone is effective at decreasing the obstructive symptoms of croup, but its onset of action is approximately 6 hours after administration. Therefore, administration of racemic epinephrine is often helpful until the steroids begin to take effect. The correct dosage of dexamethasone is important, as lower steroid dosages have proven to be ineffective in treating croup. Dexamethasone IM, or an equivalent dose of oral prednisone, may be considered in children with moderately severe croup who do not require hospitalization.

Treatment of croup. A critical review.

Although viral croup is the most common form of airway obstruction in children 6 months to 6 years of age, there is debate regarding medical care for the hospitalized patient. A complete review of the English-language literature from 1960 to 1988 was performed, using both manual and Medline searches. Critical review shows that laryngotracheitis and spasmodic croup, previously emphasized in the literature as having distinct etiologies, most likely are two ends of a broad spectrum in the clinical presentation of a single disease. Critical assessment of all prospective randomized double-blind placebo-controlled trials reported during the study period shows that there is little information on the use of humidified air or supplemental oxygen, that racemic epinephrine hydrochloride is of well-demonstrated efficacy, and that dexamethasone phosphate at a dose greater than 0.3 mg/kg is effective in decreasing the length and severity of respiratory symptoms associated with viral croup.
