An effective patient handover is a core element of high-quality patient care. Communication during patient handover in the intensive care unit is particularly challenging due to the clinical complexity and rapid changes in patient trajectories, complex interdisciplinary and interprofessional interfaces, linguistic barriers, situational and structural disruptive factors, personnel stress factors as well as the communication and error culture of the teams. In addition to avoiding disruptive factors and creating optimal communication conditions and human resources, the use of standardized and structured handovers with the help of protocols and checklists, as recommended in the literature, plays a decisive role as part of a bundle of measures for effective and safe patient care.

While genetic kidney diseases were long regarded as a rare cause of kidney failure, it has been shown in recent years that they account for a relevant proportion of cases. In cohorts of kidney transplant recipients, a monogenic cause is found in up to 30% of cases. Identifying the genetic cause of kidney disease has become much easier thanks to technological advances in DNA sequencing. The focus has now shifted to understanding the significance of the findings and identifying diagnostic gaps. It is still not possible to clarify all CKD cases of unclear aetiology. Besides very effective generic treatments for monogenic kidney disease (e.g., ACE-inhibitor use in Alport Syndrome), increasing knowledge of the pathophysiology of genetic kidney diseases has led to a growing number of targeted therapies. These include the treatment of ADPKD with Tolvaptan, which has now been in use for 10 years. Recently, exciting, and completely new approaches have been added, such as the first siRNA therapies in nephrology for primary hyperoxaluria type 1, the targeted treatment of hyperphagia in Bardet-Biedl syndrome, the therapy of APOL1-associated kidney disease or the use of the HIF-2 antagonist Belzutifan for renal cell carcinoma associated with Von-Hippel-Lindau syndrome. The new possibilities in the treatment of patients with genetic kidney diseases have also clearly revealed deficits in current patient care. Centers of excellence with extensive experience in this area therefore play an important role in improving care. This also applies to the further training of colleagues in the field. In Germany, the National Action Alliance for People with Rare Diseases (NAMSE) and the nationwide establishment of - to date - 36 centers for rare diseases play an important role in this regard.

There is a legal entitlement to participate in outpatient exercise groups in accordance with the German Social Code (Book IX) which regulates and facilitates prescriptions for patients with chronic respiratory diseases. A medical examination with specific inclusion and exclusion criteria prior to admission to an exercise group ensures safe participation.Traditional outpatient exercise groups are conducted in face-to-face groups for 60 to 90 minutes, once a week, with structured warm-up, main and cool-down phases. In addition, since the coronavirus pandemic, the introduction of online exercise groups via videoconferencing has enabled flexible participation (even without a prescription). To date, more than 11,000 German patients have participated in online exercise groups since 2021.Scientific evidence confirms the significant benefits of regular exercise, such as improved physical performance and reduced breathlessness. The psychosocial benefits and the promotion of self-efficacy are additionally supported by the supervision of a specialized trainer. Regular exercise (e.g. in outpatient exercise groups) is an inexpensive and very effective form of therapy to improve the quality of life of people with chronic respiratory diseases.

Introduction:  Renal infarction is a rare cause for an acute renal failure. At the time being, there is no sufficient correlation to the consumption of cannabis described.

Case history:  A 40-year-old male patient presented to our emergency room because of pain in the right renal bed.

Examination and findings:  The duplex ultrasound showed no ectasia, but the computed tomography confirmed a renal infraction on the right side. The further diagnostics gave no indication of a classical pathogenesis, but there was a constant consumption of cannabis documented.

Therapy and course:  We decided for a conservative treatment with analgesia, diagnostic laboratory controls and anticoagulants because of the prolonged process. The complaints decreased.

Discussion:  The correlation between thrombo-embolic events and the consumption of cannabis has to be more explored because of its recent legalization in Germany. It should be considered as a cardiovascular risk factor. Until today there are no recommendations for the anticoagulants.

Rsv (respiratory syncytial virus): RSV is a common cause of respiratory tract infections, posing a risk of severe disease, particularly for newborns and infants, as well as in older individuals with pre-existing conditions. Two safe and effective RSV vaccines were approved in 2023. These vaccines elicit protective antibodies and offer robust protection with no additional benefit from annual boosters. Both vaccines have been approved for individuals aged 60 years and older, while one of the vaccines has also been approved in pregnant women to elicit maternal immunity for passive protection of the unborn child. In Germany, RSV vaccination is currently recommended for all individuals aged 75 years and older, as well as people aged 60-74 years of age with severe underlying conditions. PNEUMOCOCCAL INFECTION: Streptococcus pneumoniae is a primary cause of community-acquired pneumonia (CAP). Since early 2022, a 20-valent conjugate vaccine (PCV20) is approved and recommended for people over 60 years of age and individuals over 18 years of age with risk factors. PCV20 replaces the 23-valent polysaccharide vaccine (PPV23) previously recommended for those over 60 years of age.

Pertussis: Although viewed primarily as a childhood disease, the majority of infections affect adults. Patients with chronic respiratory diseases are at a higher risk for severe clinical course of pertussis infection. It has therefore been recommended that all adults should get a pertussis booster with their next scheduled tetanus vaccination, given as a combination vaccine (Tdap). For risk groups (healthcare personnel, community facilities) a booster vaccination every 10 years is recommended.

Herpes zoster: Herpes Zoster (shingles) is caused by the varicella-zoster virus, and reactivations can lead to painful skin lesions and potential complications such as herpes zoster oticus, meningitis, or postherpetic neuralgia. People with chronic lung diseases such as COPD or asthma are at increased risk of herpes zoster-related complications. A recombinant adjuvanted inactivated vaccine was approved in 2018 and offers robust protection against herpes zoster and its complications. The vaccine is recommended for all people over 60 years of age and for certain risk groups over 50 years of age.

Dietary recommendations for patients on dialysis are changing as our understanding of enteral microbiotal metabolism and bioavailability of nutrients from food improves.A diet low in phosphate and potassium is recommended for patients on hemodialysis. However, the absolute content does not reflect bioavailability: How much phosphate or potassium is taken up depends on food source (plant vs. animal) and to which grade it is processed. While both are nearly 100% bioavailable from industrially processed foods (additives such as dipotassium-phosphate and other salts), a much lower proportion is taken up from unprocessed plant foods high in fibre (ca. 20-40%). The DIET-HD study showed no significant association between dietary potassium and serum potassium in > 8 000 dialysis patients; and those with the highest low-processed, fresh plant-food consumption have the best survival. Dietary fibre improves colon transit time and thereby lessens symptoms of constipation. A diet low in sodium improves blood pressure and volume management in dialysis patients. The energy and protein requirements on dialysis are high: 25-35 kcal and 1-1,2 g protein per kg body weight per day (in relation to "ideal" body weight, if patient is overweight). Protein energy wasting is associated with higher stages of kidney disease, and malnutrition is associated with worse survival on dialysis. Nutritional status should be assessed on a regular basis using validated scores, and malnutrition should be addressed and treated.

Esophageal carcinomas comprise 2 entities, squamous cell carcinoma and adenocarcinoma, which differ in pathogenesis and treatment. Elimination of inflammatory influences and risk factors, such as obesity and gastroesophageal reflux that contribute to a rising incidence of adenocarcinoma, is crucial for tumor prevention. In Germany, general endoscopic screening for upper GI tumors is not recommended, whereas endoscopic surveillance is applied in the presence of Barrett's metaplasia. In the future, better prediction models will be needed to identify patients at risk who will benefit from endoscopic surveillance. Precancerous lesions and early tumor stages can be removed endoscopically using modern resection methods. In recent years, therapeutic strategies for advanced esophageal tumors have undergone significant changes. In the multimodal treatment of locally advanced stages, radiochemotherapy remains to play a key role for squamous cell carcinoma, whereas new evidence highlights the importance of perioperative chemotherapy for the optimal management of adenocarcinoma. Systemic treatment options for both tumor entities have been significantly expanded due to the successful use of immune checkpoint inhibitors in adjuvant and palliative treatment regimen. Determination of PD-L1 and MSI status has therefore become decisive for the choice of therapy. In metastatic stages of adenocarcinoma, chemotherapy can now be supplemented by multiple antibodies directed against Her2, PD1, or claudin 18.2, and the antibody-drug conjugate trastuzumab deruxtecan has become a Her2-targeted option in second line treatment.

Dizziness is one of the most common reasons for medical consultations. The interdisciplinary range of differential diagnoses often leads to difficulties in proper classification. Artificial Intelligence and machine learning can assist through data-driven algorithms and facilitate the collection of important clinical signs as digital biomarkers. The article will present and critically discuss the current evidence on the topic.
