Protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and associated clinical sequelae requires well-coordinated metabolic and immune responses that limit viral spread and promote recovery of damaged systems. However, the role of the gut microbiota in regulating these responses has not been thoroughly investigated. In order to identify mechanisms underpinning microbiota interactions with host immune and metabolic systems that influence coronavirus disease 2019 (COVID-19) outcomes, we performed a multi-omics analysis on hospitalized COVID-19 patients and compared those with the most severe outcome (i.e. death, n = 41) to those with severe non-fatal disease (n = 89), or mild/moderate disease (n = 42), that recovered. A distinct subset of 8 cytokines (e.g. TSLP) and 140 metabolites (e.g. quinolinate) in sera identified those with a fatal outcome to infection. In addition, elevated levels of multiple pathobionts and lower levels of protective or anti-inflammatory microbes were observed in the fecal microbiome of those with the poorest clinical outcomes. Weighted gene correlation network analysis (WGCNA) identified modules that associated severity-associated cytokines with tryptophan metabolism, coagulation-linked fibrinopeptides, and bile acids with multiple pathobionts, such as . In contrast, less severe clinical outcomes are associated with clusters of anti-inflammatory microbes such as or , short chain fatty acids (SCFAs) and IL-17A. Our study uncovered distinct mechanistic modules that link host and microbiome processes with fatal outcomes to SARS-CoV-2 infection. These features may be useful to identify at risk individuals, but also highlight a role for the microbiome in modifying hyperinflammatory responses to SARS-CoV-2 and other infectious agents.

The article presents the Choosing wisely (CHW) approach to selected problems of internal medicine, as developed by professional societies in the USA, Great Britain, Canada, Australia and the Federal Republic of Germany. It deals in more detail with issues and procedures in specialized fields of nephrology and rheumatology. There are negative, but also some positive recommendations on how the CHW approach views them.

Plantar dermatoses (PD) are common, occurring either spontaneously on healthy skin or developing secondarily from previously established foot disease. PD share similar symptoms and morphology, making them challenging to differentiate. A few of the most frequently encountered PD include tinea pedis, psoriasis, contact dermatitis, dyshidrotic dermatitis (or recurrent vesicular palmoplantar dermatitis), and juvenile plantar dermatosis. This review offers practical advice for diagnosing and treating the most common PD in the primary care office.

Chronic Intestinal Pseudo-obstruction (CIPO) is a rare but debilitating and severe form of gastrointestinal dysmotility. The diagnosis is often made very late in the disease course due to its rarity and complexity. Treatment is mainly supportive, as there is no definitive cure. Pharmacologic therapy comprises prokinetics, antibiotics for bacterial overgrowth and pain management. Pain can also be alleviated with intestinal decompression in selected cases. Beside the pharmacologic therapy, nutrition and fluid replacement play a key role. Rarely, intestinal transplantation is necessary in patients with CIPO and intestinal failure. In this review, we describe an advanced CIPO case and provide an update of the clinical and diagnostic features and current management strategies. The goal of our review is to raise awareness around CIPO and to give practical guidance for the clinician.

As generalized pruritus can be a symptom of a systemic disease, iron deficiency may be the underlying internal cause of its symptoms. Because data on the relationship between iron deficiency and generalized chronic pruritus are limited, more research is needed to ensure proper diagnosis and management.

Headache is common in the puerperium, with a wide variety of underlying aetiologies. We describe a unique case of postpartum headache after accidental dural puncture with a Tuohy needle in a previously healthy woman during a combined spinal-epidural for labour analgesia. Initially, a post-dural puncture headache was diagnosed. Eclampsia was subsequently suspected after the development of complex partial seizures and proteinuria 5 days postpartum. After neurological examination and neuroimaging, however, the diagnoses of reversible cerebral vasoconstriction syndrome and posterior reversible encephalopathy syndrome were confirmed. We hypothesise that accidental dural puncture which resulted in post-dural puncture headache may have delayed the diagnosis of other headache aetiologies and may have acted as a trigger for the development of cerebral vasospasm syndromes. This case demonstrates the importance of a careful assessment of postpartum headaches and the need for a high degree of diagnostic suspicion in cases of refractory post-dural puncture headache. In these cases, neurological referral and neuroimaging evaluation should be considered. We highlight the importance of multidisciplinary team including anaesthetists, obstetricians and other clinicians.

Chemotherapy-induced neuropathic pain (CINP) is intractable, and spinal cannabinoid receptors (CBRs) are potential therapeutic targets for CINP. Previous studies demonstrated that hyperbaric oxygen (HBO2) may contribute in alleviating specific peripheral neuropathic pain. However, neither CINP nor CBR have been clarified. We hypothesized that HBO2 is capable of alleviating CINP, and the effect could be explained by the activation of spinal CBRs.

Prinzmetal angina is one of the causes of acute coronary syndromes, the exact etiology of which is still unknown. Here we introduce a 27-year-old man with no history of cardiovascular disease, with a history of hospitalization due to acute pericarditis in the previous month, who was discharged with a good response to ibuprofen treatment but had clinical and electrocardiographically recurrence of pericarditis with compressive retrosternal chest pain and electrocardiogram (ECG) changes in favor of acute infero-postero-right ventricular (RV) myocardial infarction (MI). Treatment with vasodilator improved compressive retrosternal chest pain and reversed acute myocardial infarction changes completely and left pleuritic chest pain and pericarditis changes in the ECG. Due to the typical chest pain, he was admitted to the emergency room; ECG revealed generalized ST-segment elevation with acute pericarditis pattern again. Acute infero-posterior and right ventricular acute myocardial infarction pattern was also evident. After treatment with nitroglycerin in the Critical Cardiac Unit (CCU), all ECG ischemic changes returned to baseline, and pericarditis remained in all leads. The patient was discharged with non-steroidal anti-inflammatory drugs (NSAIDs), calcium channel blockers, and a good general condition.
