Background: In 2020, around 1.4 million new prostate cancer (PCa) cases were recorded worldwide. Early detection of PCa by prostate-specific antigen (PSA) screening remains debated, leading to different specialist-specific recommendations in PCa guidelines. This study aimed to assess attitudes toward and use of PSA testing among urologists in Germany and general practitioners (GPs) in Lower Saxony (Germany). Methods: A nationwide questionnaire was sent to urologists via the mailing lists of the Professional Association of German Urologists and the German Urological Society. A version of the questionnaire for GPs was sent to email addresses via the Association of Statutory Health Insurance Physicians Lower Saxony. The online questionnaires covered use of PSA testing, information communication, handling of test results, and handling of/knowledge about national and international guidelines and recommendations on early detection of PCa. Statistical analysis was performed at a descriptive level. Results: In total, 432 of 6,568 urologists (6.6%) and 96 of 1,579 GPs (6.1%) participated in this survey. Urologists and GPs differed in their attitudes and approaches toward PSA testing. Most urologists (86.8%, n=375) judged the test as "very meaningful" or "meaningful", compared with 52.1% (n=50) of GPs. Almost two-thirds of the urologists (64.4%, n=278) viewed the PCa mortality reduction by PSA testing as proven, compared with one-fifth of GPs (20.8%, n=20). Almost 80% of male urologists (79.9%, n=291) indicated that they would undergo a PSA test in the future (again), compared with 55.1% of male GPs (n=38). In addition, 56.3% (n=243) of urologists stated that "considerably more than half" or "almost all" men aged 45 years or older received a PSA test, compared with 19.8% (n=19) of GPs. Conclusions: Urologists are more convinced about the PSA test than GPs. PSA testing is therefore used more often in urological settings, although the preselected patient population must be considered. In accordance with specialist-specific recommendations, GPs show a more reserved approach toward PSA testing. Instead of focusing on different attitudes and recommendations on PSA testing, the exchange between specialist groups should be improved to achieve a consistent approach to PSA testing.

Background: Erythema migrans represents an early cutaneous and most common manifestation of Lyme borreliosis. Recommendations regarding pharmacological agents, dose and duration of treatment are subject of intense debate. This review aims to explore differences in efficacy and safety between pharmacological treatments and control treatment. Methods: To identify relevant studies, we will conduct a systematic literature search. We will include randomised controlled trials (RCTs) and non-RCTs. Eligible comparative studies need to (1) consider patients with a diagnosis of erythema migrans resulting from Lyme borreliosis and (2) compare different pharmacological agents against each other, against any other non-pharmacological treatment, placebo or no treatment. Two review authors will independently assess included studies for risk of bias according to the methods of the Cochrane Handbook for Systematic Reviews of Interventions and related to specific study designs. We will address patient-relevant outcomes including clinical remission of cutaneous symptoms, any treatment-related adverse events, quality of life and progressive symptoms such as neuroborreliosis or Lyme carditis and flu-like symptoms. Provided that the identified trials are comparable in terms of clinical issues, combined estimates will be provided. Estimations of treatment effects will be calculated based on a random effects model. Heterogeneity will be evaluated based on I² and chi-square test. In case of significant heterogeneity, a pooled estimate will not be provided, but heterogeneity will be investigated on the basis of methodological and clinical study aspects. We plan subgroup analysis to reveal potential differences in the effect estimates between patient populations and treatment specifications. We will consider risk of bias using sensitivity analyses to decide whether to rely on the pooled estimates. The quality of a body of evidence for individual outcomes will be assessed using the GRADE approach. Discussion: Benefits and harms of pharmacological treatment in erythema migrans have not yet been adequately assessed. This systematic review will evaluate and summarise available evidence addressing benefits and harms of different pharmacological treatments. In addition, this summary of clinical evidence will inform decision-making between clinicians and patients and will play an important part in patient care. [ABSTRACT FROM AUTHOR]

Background: Antibiotic resistance is a worldwide problem and inappropriate prescriptions are a cause. Especially among children, prescriptions tend to be high. It is unclear how they differ in bordering regions. This study therefore examined the antibiotic prescription prevalence among children in primary care between northern Netherlands and north-west of Germany. Methods: Two datasets were used: The Dutch (IADB) comprises representative data of pharmacists in North Netherland and the German (BARMER GEK) includes nationwide health insurance data. Both were filtered using postal codes to define two comparable bordering regions with patients under 18 years for 2010. Results: The proportion of primary care patients receiving at least one antibiotic was lower in northern Netherlands (29.8 %; 95 % confidence interval [95 % CI]: 29.3-30.3), compared to north-west Germany (38.9 %; 95 % CI: 38.2-39.6). Within the respective countries, there were variations ranging from 27.0 to 44.1 % between different areas. Most profound was the difference in second-generation cephalosporins: for German children 25 % of the total prescriptions, while for Dutch children it was less than 0.1 %. Conclusions: This study is the first to compare outpatient antibiotic prescriptions among children in primary care practices in bordering regions of two countries. Large differences were seen within and between the countries, with overall higher prescription prevalence in Germany. Considering increasing cross-border healthcare, these comparisons are highly valuable and help act upon antibiotic resistance in the first line of care in an international approach.

Objectives: While gout is a well-known entity, little research has been conducted on its pathophysiology. There is growing evidence that women with hyperuricemia are at higher cardiovascular risk than men with hyperuricemia. We aim to evaluate whether gender-specific cut-offs should be considered.Study Design: Cross-sectional study (the German Health Interview and Examination Survey for Adults; DEGS1).Main Outcome Measures: Self-reported gout or hyperuricemia and uric acid level.Results: Of 6,918 participants (mean age 47.2 years; 50.5% females), 9.7% had had a diagnosis of hyperuricemia or gout at least once in their lifetime. Men were nearly twice as often affected as women (12.9 vs. 6.5%). In women, the prevalence of cardiovascular and renal diseases increased with higher uric acid level to a much greater extent than in men. This association remained in multivariate analyses.Conclusions: No commonly accepted cut-off value for uric acid has been established. Overall, women were at lower risk of hyperuricemia. However, women were at higher risk of having cardiovascular and renal comorbidities, even at lower uric acid levels. Our results are in line with the accumulating evidence that we should consider gender in gout and hyperuricemia. [ABSTRACT FROM AUTHOR]

Background: Neuroborreliosis is a tick-borne infectious disease of the nervous system caused by Borrelia burgdorferi. Common clinical manifestations of neuroborreliosis are cranial nerve dysfunctions, polyradiculoneuritis, and meningitis. Diagnosis is usually based on clinical presentation, serologic testing, and analysis of cerebrospinal fluid. Many aspects of pharmacological treatment, such as choice of drug, dosage, and duration are subject of intense debate, leading to uncertainties in patients and healthcare providers alike. To approach the questions regarding pharmacological treatment of neuroborreliosis, we will perform a systematic review., Methods: We will perform a comprehensive systematic literature search for potentially eligible studies that report outcomes after pharmacological interventions. To adequately consider the wealth of research that has been conducted so far, this review will evaluate randomized controlled trials (RCTs) and non-randomized studies on treatment of neuroborreliosis. We will assess potential risk of bias for each RCT meeting our selection criteria using the Cochrane risk of bias tool for RCTs. For non-randomized studies, we will use the Newcastle-Ottawa Scale and the recently piloted Cochrane risk of bias tool for non-randomized studies. Our primary outcome of interest will be neurological symptoms and the secondary outcomes will be disability, patient-reported outcomes (quality of life, and, if reported separately from other neurological symptoms, pain, fatigue, depression, cognition, and sleep), adverse events, and cerebrospinal fluid pleocytosis. Pooling of data and meta-analysis will only be deemed justified between studies with similar design (e.g., RCTs are only combined with other RCTs), characteristics (e.g., similar populations), and of acceptable heterogeneity (I2 < 80%). Pooled estimates will be calculated using RevMan software. Prespecified subgroup analyses will evaluate groups of antibiotics, length of antibiotic treatment, and different doses of doxycycline. We will assess the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach., Discussion: This systematic review will summarize the available evidence from RCTs and non-randomized studies regarding pharmacological treatment of neuroborreliosis. The available evidence will be summarized and discussed to provide a basis for decision-making for patients and healthcare professionals., Systematic Review Registration: PROSPERO registration number: CRD42014008839.

Purpose of Review: Given the continuous relations of blood pressure to cardiovascular risk, any definition of high blood pressure is arbitrary, and based on thresholds at which there is clear evidence that treatment benefits outweigh potential risks. This review examines what constitutes optimal blood pressure., Recent Findings: A recent report raised the possibility of an age- and sex-dependent threshold for risk associated with systolic blood pressure, questioning the use of a single threshold (such as 140/90 mmHg) for defining hypertension. Several subsequent studies have questioned this notion and reemphasized that lower blood pressure levels are associated with less morbidity and mortality even within the nonhypertensive range. A recent meta-analysis confirmed that a blood pressure of 115/75 mmHg is associated with minimal vascular mortality and likely constitutes optimal blood pressure. Such blood pressure levels are infrequent in westernized societies. The target blood pressure goal for treated hypertensives is higher at 140/90 mmHg but is infrequently achieved. Select individuals at high absolute risk of cardiovascular disease events and/or with specific conditions (notably diabetes, renal insufficiency and prior vascular disease) may benefit from blood pressure lowering below this threshold., Summary: At a population level, a blood pressure of 115/75 mmHg seems optimal because it is associated with minimal vascular risk. Over half of all hypertensives do not have their blood pressure controlled underscoring the challenges facing health care providers. Efforts should be strengthened for the primary prevention of hypertension and the promotion of optimal blood pressure through lifestyle measures.

Increased brain natriuretic peptide (BNP) expression in the ventricles antedates elevated blood pressure (BP) in experimental studies. We hypothesized that higher plasma BNP levels in nonhypertensive individuals may be associated with a greater likelihood of future BP increase and/or hypertension. We evaluated the relations of plasma BNP to longitudinal BP tracking and incidence of hypertension in 1801 nonhypertensive Framingham Heart Study participants (mean age, 56 years; 57% women) by using gender-specific multivariable logistic regression. Progression of BP stage was defined as an increment of one or more BP categories, as classified by the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI). Hypertension was defined as a systolic BP > or =140 or diastolic BP > or =90 mm Hg or use of antihypertensive medications. On follow-up 4 years from baseline, progression of BP category was observed in 36.2% of men and 33.1% of women; hypertension developed in 16.4% of men and 15.5% of women. In multivariable models adjusting for known risk factors, elevated plasma BNP level was associated with increased risk of BP progression in men (odds ratio of 1.15 for trend across categories, P=0.046) but not in women (P=0.82). There were no significant trends of increasing incidence of hypertension across BNP categories in men or women. In our community-based sample, higher plasma BNP levels were associated with increased risk of BP progression in men but not women. Additional investigations are warranted to confirm these findings and elucidate the basis for these gender-related differences.

Congestive heart failure (CHF) is a disease condition that is increasing in prevalence and is associated with significant morbidity and mortality. Left ventricular systolic dysfunction (LVSD) is a treatable precursor of CHF, but remains asymptomatic in about half of the individuals afflicted. This observation has spurred interest in screening for LVSD. Plasma B-type natriuretic peptide (BNP) is a widely accepted test for the diagnosis of overt CHF. In this review, we examine the potential role for plasma BNP as a screening tool for asymptomatic LVSD. The performance of any screening test depends on its accuracy, the prevalence of the disease condition screened for, and the availability of resources for follow-up of individuals in whom the disease was detected. In the context of community-wide screening for LVSD, a test with high specificity would be important so as to minimize the costs of expensive definitive follow-up tests (i.e. echocardiography). The prevalence of significant LVSD (ejection fraction 20.40) is low, limiting the enthusiasm for a screening program targeting the general population. This is especially true for women, in whom the condition is rare, and the performance characteristics of plasma BNP are sub-optimal. In men, plasma BNP may be a useful screening test in high-risk individuals in whom there are no other clinical indications for echocardiography. The choice of the appropriate plasma BNP threshold that triggers further work-up in such high-risk individuals may vary according to the availability of resources, and with the healthcare priorities of a community.
