Multicenter Study Comparative Study
Prediction of life expectancy in patients with primary pulmonary hypertension. A retrospective nationwide survey from 1980-1990.
Primary pulmonary hypertension (PPH) is a progressive disease of unknown etiology usually followed by death within 5 years after diagnosis. Although heart-lung or lung transplantation is now offered to patients with advanced PPH, adequate criteria assessing an accurate prediction of life expectancy in PPH has been difficult to establish. The aims of this study were to identify the characteristic features associated with a poor prognosis in patients with PPH, and to attempt to establish an individual prognostic index that predicts with great accuracy survival or death of PPH after one year, thereby helping to define criteria for patient selection for transplantation. ⋯ As the independent factors, PPA, PRA, SI, and PaCO2 were selected for the multiple logistic analysis. Using a 0.7 probability cut-point to separate Nonsurvivors from Survivors, 84.6% of Nonsurvivors and Survivors could be correctly predicted from this logistic regression equation. Predictive equations like the present preliminary one can be used in the future to better assess life expectancy in patients with PPH in whom transplantation will be considered.

Lessons learnt during the national introduction of human papillomavirus (HPV) vaccination programmes in 6 African countries: Stakeholders' perspectives.
Infection with human papillomavirus (HPV) significantly increases the risk of developing cervical cancer later in life. Therefore, globally, HPV vaccines targeted to pre-adolescent and adolescent girls have been on the rise since the licensure in 2006. However, the introduction of HPV vaccines has been relatively slow in Africa. At the end of 2016, only 8 of the 54 countries in Africa were reported to have introduced HPV vaccination at a national level. By 2019, the number of countries had grown marginally to 11. ⋯ Most African countries do not have established platforms to deliver vaccines to pre-adolescent and adolescent populations. The successful introduction of the HPV vaccine through school-based vaccination strategies in African countries may have created a platform to deliver other adolescent vaccines. The similarity of the study findings across the 6 participating countries further strengthens the need to document and disseminate the challenges and lessons learnt during HPV vaccine introduction in Africa. Documentation and dissemination of the challenges and lessons learnt are useful to other countries in Africa that plan to introduce an HPV vaccination programme, and possibly other adolescent vaccines.

Randomized Controlled Trial Multicenter Study
Duloxetine versus routine care in the long-term management of diabetic peripheral neuropathic pain.
Duloxetine hydrochloride is a dual reuptake inhibitor of both serotonin and norepinephrine. In the present open-label study, the safety of duloxetine at a fixed-dose of 60 mg twice daily (BID) for up to 52 weeks was evaluated and compared to routine care in the therapy of patients diagnosed with diabetic peripheral neuropathic pain (DPNP). ⋯ In this study, duloxetine was safe and well tolerated compared to routine care in the long-term management of patients with DPNP.

Multicenter StudyCardiopulmonary resuscitation in pediatric intensive care units.
To determine the effectiveness of cardiopulmonary resuscitation (CPR) in the pediatric intensive care unit (ICU). ⋯ Pediatric ICU cardiac arrest is an uncommon event. When it does occur, prehospital CPR, duration of resuscitation, traumatic etiology, and severity of illness are important factors associated with survival.

Randomized Controlled Trial Multicenter Study Comparative Study
CT angiography for safe discharge of patients with possible acute coronary syndromes.
Admission rates among patients presenting to emergency departments with possible acute coronary syndromes are high, although for most of these patients, the symptoms are ultimately found not to have a cardiac cause. Coronary computed tomographic angiography (CCTA) has a very high negative predictive value for the detection of coronary disease, but its usefulness in determining whether discharge of patients from the emergency department is safe is not well established. ⋯ A CCTA-based strategy for low-to-intermediate-risk patients presenting with a possible acute coronary syndrome appears to allow the safe, expedited discharge from the emergency department of many patients who would otherwise be admitted.
