Aim of the study: Oral immunotherapy (OIT) is increasingly used for the treatment of childhood food allergies, with limited data available on cashew nut OIT. This real-life study investigated the safety and feasibility of cashew nut OIT, comparing it with peanut OIT, with a focus on the up-dosing process.

Methods: We analysed cashew nut (n = 24) and peanut (n = 38) OIT cases with treatment initiated between 2018 and 2022 at the University Children's Hospital Basel. All patients who commenced therapy within this time frame were enrolled without prior selection. Two different starting protocols were used. Within the up-dosing protocol, the nut intake was incrementally increased by 20-30% every 2 weeks until reaching a maintenance dose of 1 g of nut protein. After consuming the maintenance dose regularly for 18-24 months, a second oral food challenge was performed. Patients who passed this challenge were considered desensitised. The safety of the therapy was evaluated based on the severity of adverse reactions during the up-dosing phase. Symptom severity was evaluated using the validated ordinal food allergy severity scale (o-FASS-5).

Results: Over the study period, 33% of cashew nut-allergic and 63% of peanut-allergic patients experienced mild to moderate allergic reactions. Severe allergic reactions occurred in five peanut-allergic children with high baseline allergen-specific IgE levels. Six patients with peanut, and none with cashew nut OIT, discontinued the therapy due to adverse reactions. The mean duration to reach the maintenance phase was longer for children with asthma or another food allergy. Among children who already underwent the second oral food challenge, desensitisation was achieved in 91% (11 out of 12) of cashew nut- and 73% (11 out of 15) of peanut-allergic patients.

Conclusion: Cashew nut OIT had a low severity of adverse reactions and was generally well-tolerated. However, patient characteristics influenced side effect risk and treatment duration, emphasising the need for individualised OIT strategies.

Cardiac amyloidosis is a disease characterised by the accumulation of amyloid protein in the heart tissue. There are several types of amyloidosis, but the most common types affecting the heart are ATTR amyloidosis (caused by transthyretin protein) and AL amyloidosis (caused by abnormal immunoglobulin light chains). Cardiac amyloidosis causes typical signs and symptoms of heart failure. Diagnosis involves a combination of imaging tests such as echocardiography and cardiac magnetic resonance imaging, as well as nuclear imaging scans and tissue biopsies to confirm the presence of amyloid deposits in the heart. Treatment of cardiac amyloidosis depends on the type and severity of the disease and includes medications to manage symptoms as well as treatments targeting the underlying cause of amyloidosis. Importantly, cardiac amyloidosis is a serious condition requiring specialised care from a multidisciplinary team including cardiologists and haematologists as well as other specialists familiar with the management of this rare disease. This is crucial, as early diagnosis and treatment are important for improving outcomes.

Aims of the study: Arterial hypertension is a major global health risk. Global surveys indicate that only half of patients with arterial hypertension receive pharmacotherapy, and only a quarter achieve the primary blood pressure target recommended by guidelines. This study aimed to evaluate the achievement of the primary blood pressure target in Swiss general practice, provide insights into arterial hypertension treatment, and identify factors associated with achieving this goal.

Methods: This cross-sectional study utilised data from a large Swiss primary care database. Patients with arterial hypertension, aged ≥18 years, who underwent blood pressure monitoring in 2021 were included. The primary observation was blood pressure control, defined as the achievement of the primary blood pressure target of systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg. Demographic data from physicians and patients, blood pressure measurements, comorbidities, cardiovascular risk factors, and pharmacotherapy were collected, and arterial hypertension stages were calculated. Unadjusted and multivariable-adjusted mixed logistic regression models were used to identify factors associated with blood pressure control.

Results: A total of 49,290 patients were included, of whom 23,933 (48.6%) were female. The median patient age was 71 years (interquartile range 61-80). Blood pressure control was observed in 23,022 patients (46.7%), and 36,692 patients (74.4%) had an antihypertensive pharmacotherapy prescription. In multivariable analysis, blood pressure control was positively associated with arterial hypertension stage, antihypertensive pharmacotherapy, the intensity of blood pressure monitoring, and the number of blood pressure-increasing drugs, but negatively associated with a long-standing arterial hypertension, female sex, and old age.

Conclusions: While general practitioners appear to consider arterial hypertension stages in their treatment strategies, there is still room for improvement in arterial hypertension care by prescribing pharmacotherapy, especially in patients with long-standing arterial hypertension, female sex and old age.

Aim: To assess and compare the real-world management of catheters and catheter-associated urinary tract infections (CAUTI) among Swiss general practitioners and urologists, encompassing diagnosis, treatment and prophylaxis.

Methods: An anonymised online questionnaire was distributed among Swiss general practitioners and urologists between January and October 2023 via the networks of Sentinella and the Swiss Association of Urology. The questionnaire consisted of questions on catheter management, including diagnosis, treatment and prophylaxis of CAUTI. Analysis was performed by discipline. Fisher's exact test was applied for comparisons (statistical significance with p <0.05).

Results: Out of 175 participating physicians, the majority were involved in catheter management. Urologists exhibited significantly higher levels of competence as compared to general practitioners (67.1% vs 20.9%). Although no significant differences were observed regarding diagnostic approaches between disciplines, unrecommended diagnostic methods were frequently applied. general practitioners reported that they treated non-febrile CAUTI for longer durations, while urologists indicated that they treated febrile CAUTI longer. Additionally, the use of fluoroquinolones was more prevalent among general practitioners compared to urologists, while prophylactic measures were more frequently applied by urologists.

Conclusions: Catheter and CAUTI management entail significant uncertainty for general practitioners. CAUTI management varied notably between general practitioners and urologists in terms of treatment and prophylaxis. The use of non-recommended diagnostic approaches and drugs was common. This trend, along with inappropriate diagnostic methods and prophylaxis, may increase antimicrobial resistance and CAUTI morbidity. The study emphasises the necessity for diagnostic and antimicrobial stewardship interventions, and proper training in CAUTI management for general practitioners and urologists.

Electroconvulsive therapy is an effective and well-tolerated antidepressant treatment for the elderly population. The place of electroconvulsive therapy in the treatment sequence for depression in the elderly is currently not well established. This review aims to identify the factors that contribute to a positive response and remission in elderly patients with depression undergoing electroconvulsive therapy treatment. We searched five bibliographic databases (Medline ALL Ovid, Embase.com, APA PsycInfo Ovid, Cochrane Library Wiley and Web of Science Core Collection) for articles published between 1995 and June 2023. Of the 2149 articles screened, 19 were included in the review. No significant associations were found between remission and/or response and salivary cortisol, baseline hippocampal and white matter hyperintensities, total amyloid load or global cortical atrophy. The reviewed articles did not show a significant difference in remission between unilateral and bilateral electroconvulsive therapy treatment. Other interesting findings are that moderately elevated levels of CRP and S100B levels, lower retardation scores, poorer performance on the word reading task at baseline and longer post-ictal reorientation time may be associated with higher remission and/or response rates. Medial temporal atrophy can be associated with lower Montgomery-Åsberg Depression Rating Scale (MADRS) decrease after electroconvulsive therapy. Finally, elderly patients had higher rates of electroconvulsive therapy response; retardation and psychotic features may mediate this association. Incorporation of this data into clinical practice may facilitate a personalised approach to electroconvulsive therapy. However, research on this topic is scarce and there are few studies that focus specifically on older people.

Background and aims of the study: Congenital syphilis is a rare complication of syphilis in pregnant women. Vertical transmission may occur at any time during pregnancy. The incidence of congenital syphilis has been increasing worldwide. Congenital syphilis has been a notifiable disease for many years in Switzerland but reporting does not include maternal features associated with syphilis in pregnancy or infant's subsequent development. We described syphilis cases among pregnant women screened over a 10-year period in Switzerland and subsequent cases of congenital syphilis, in order to identify maternal risk profiles and to optimise prevention. Second, we compared the characteristics of pregnant women screened early (1st trimester) vs late in pregnancy (2nd or 3rd trimester). Finally, we assessed the risk factors for premature birth among these women with syphilis.

Methods: A multicentre retrospective study conducted in Swiss hospitals from 2012 to 2021, including pregnant women who screened positive for syphilis (Treponema pallidum haemagglutination assay [TPHA] / T. pallidum particle agglutination assay [TPPA ] ≥1:80) and newborns exposed to T. pallidum in utero and/or congenitally infected and with a positive syphilis serology at birth. Data were collected from medical records.

Results: A total of 147 syphilis-positive pregnant women and 102 infants were included. A history of treated syphilis was known for 44% (65/147) of the mothers corresponding to a serological scar and the remaining 56% (82/147) were newly identified syphilis cases. Syphilis screening was done during the first trimester in 54%, second trimester in 29% and third trimester in 13% of cases. Two babies were diagnosed with congenital syphilis (1.96%). Several potential factors that could contribute to women's risk of syphilis during pregnancy were identified such as a foreign origin (93% of mothers), lack of healthcare insurance (25%), no employment status (37%), drug use (5%), co-infection with other sexually transmitted infections (24%) and a late first antenatal consultation (42%). The number of pregnant women without insurance was higher in women diagnosed in the second or third trimester than in those diagnosed in the first trimester (odds ratio 0.41; 95% CI 0.19-0.89; p = 0.024). Syphilis diagnosed in the second or third trimester was associated with a late first antenatal consultation (odds ratio 77.82; 95% CI 9.81-617.21; p <0.001). A high rate of intrauterine growth retardation and of preterm birth was observed in newborns (18% versus 6% in Switzerland in 2022).

Conclusion: Congenital syphilis remains rare in Switzerland. However, we found potential maternal factors associated with a positive syphilis serology during pregnancy, which can help to improve future prevention measures. The study protocol was registered on ClinicalTrials.gov (ID NCT05975502).
