Background: Guidelines recommend hepatitis B virus (HBV) vaccination of all adults positive for human immunodeficiency virus (HIV). Immune responses to single-antigen HBV vaccine among HIV-positive patients are low when compared with HIV-negative adults. Sci-B-Vac™ is a recombinant third-generation HBV that may be advantageous in this population.
Objectives: To examine the immune responses to Sci-B-Vac among HIV-positive adults.
Methods: We conducted a prospective cohort study involving HIV-positive adults who had negative HBV serology (HBSAg, HBSAb, HBcoreAb). Sci-B-Vac at 10 µg/dose was administered intramuscularly upon recruitment and after 1 and 6 months. HBSAb levels were checked 1 month after each dose; a level > 10 mlU/ml was considered protective. Data regarding age, gender, CD4 level, and viral load were collected.
Results: The study group comprised 31 patients. Average CD4 count was 503 ± 281 cells/ml, and average viral load was 44 copies/ml. Median interquartile range (IQR) HBVAb titers after the first, second and third immunizations were 0 (0, 3.5), 30 (6, 126) and 253 (81, 408) mlU/ml. Significant titer elevations were found between the second and third immunizations (P = 0.0003). The rate of patients considered protected was 16% after the first, 65% after the second (P < 0.0001), and 84% after the third dose (P = 0.045). No adverse events were reported. More patients under the age of 40 years responded to the first immunization (28% vs. 0%, P = 0.038). CD4 level had no influence on immunization rates.
Conclusions: Sci-B-Vac might achieve better immunization rates among HIV-positive adults compared to the single-antigen vaccine and thus deserves further evaluation in a randomized, double-blind study in this population.

Background: The optimal approach to the evaluation of asymptomatic bacteruria in stroke patients is uncertain.
Objectives: To compare elderly patients after an acute stroke with and without asymptomatic bacteriuria for the development of symptomatic urinary tract infections (UTI).
Methods: We prospectively monitored patients over 65 years of age admitted to our rehabilitation hospital after an acute stroke, with and without asymptomatic bacteriuria, for the development of symptomatic UTIs. The prevalence of bacteriuria was determined by urine cultures obtained 2 and 4 weeks after admission. Patients with and without persistent bacteriuria were compared to identify variables associated with bacteriuria.
Results: Fifty-five patients were included in the study. The prevalence of asymptomatic bacteriuria at baseline was 20%. Of all 55 stroke patients, 13 (23.6%) developed a symptomatic UTI during the 30 day follow-up. Patients with stroke and asymptomatic bacteriuria at baseline had an increased risk of developing a symptomatic UTI (54.5% with asymptomatic bacteriuria vs. 15.9% without, P = 0.011). To exclude the effects of several confounders, we performed multivariate Cox regression analysis, which showed that bacteruria remained a significant covariate for symptomatic UTI (hazard ratio 2.86, 95% confidence interval 0.71–10.46, P = 0.051). When subjects who experienced symptomatic urinary infection were included, the prevalence of bacteriuria in the study cohort declined to about 45.5% by 30 days.
Conclusion: Elderly patients with stroke and asymptomatic bacteriuria have an increased risk of developing a symptomatic UTI compared to those without asymptomatic bacteriuria during a 30 day post-stroke follow-up.

Background: Transcatheter tricuspid valve-in-valve implantation (TVIV) is an attractive yet under-explored alternative to redo valve surgery.
Objectives: To report the multicenter TVIV experience in Israel.
Methods: We approached multiple centers and collected data regarding seven TVIV cases.
Results: The study group comprised seven participants: five females and two males, with a mean age of 63 ± 12 years and EuroSCORE-II 13.6 ± 3.3%. Follow-up ranged from 3 to 21 months (mean 8 ± 6 months). All presented with advanced heart failure. The indication for valve intervention was a predominant tricuspid stenosis in three patients, significant tricuspid regurgitation in one and a mixture in three. Six procedures were conducted via a transfemoral approach and one by transatrial access. The Edwards SAPIENTM XT valve was used in four cases and the SAPIENTM 3 in three. Without pre-stenting/rapid pacing, all participants underwent successful valve implantation. Mean transvalvular gradient decreased from 11 ± 3 mmHg to 6 ± 3 mmHg (P = 0.003) and regurgitation decreased from moderate/severe (in four cases) to none/trace (in six of the seven cases). One patient remained severely symptomatic and died 3.5 months after the implantation. All others achieved a functional capacity improvement and amelioration of symptoms soon after the implantation, which persisted during follow-up.
Conclusions: TVIV may be a safe and effective strategy to treat carefully selected patients with degenerated bioprosthetic tricuspid valve at high operative risk.

Background: Arthritis and arthralgia are painful symptoms experienced by many elderly patients during hospitalization. Crystal-induced arthritis (CIA) is one of the most common causes of arthritis worldwide and represents the most common cause of acute arthritis in the elderly.
Objective: To determine the incidence of both acute new onset or acute exacerbation of CIA among elderly patients hospitalized due to an acute medical illness.
Method: This study comprised 85 patients. Patients aged 70 years and older who complained of any articular pain were included in the study. Exclusion criteria were signs of septic arthritis, chronic use of steroids or non-steroidal anti-inflammatory drugs, or admission to the hospital due to an acute attack of CIA.
Results: Synovial aspiration was performed in 76 patients (89%). Joint aspiration yielded a diagnosis in 67 of them (79%). The predominant type of crystal was calcium pyrophosphate dehydrate (68%) followed by monosodium urate (20%). The main causes of hospitalization were acute infectious disease (57%) followed by neurologic and cardiac diseases, 14% and 9% respectively, and orthopedic problems (6%). Among patients with acute infectious disease, the main causes were pulmonary (57%) and gastrointestinal (22%) infections. In 9 patients (12%) who underwent synovial aspiration, visible crystals were identified without a definite diagnosis.
Conclusion: Our study showed that hospitalization could be a risk factor for the development of CIA, and the time to diagnose CIA is during hospitalization for other acute illnesses.
