Background: Group B Streptococcus () is one of the colonizing bacteria in pregnant women which can be a causative agent of meningitis and neonatal sepsis. This organism has also been increasingly related to invasive infections in non-pregnant adults. Objective: In present study, we aimed to characterize the clonality of biofilm-producing isolates from various sources from two different clinical laboratories in Tehran, Iran.Materials and Methods: isolates were collected from community-acquired (CA) and hospital-acquired (HA) infections in pregnant and non-pregnant adults. The antimicrobial susceptibility patterns and biofilm formation ability were determined. In addition, pulse field gel electrophoresis (PFGE) was used to verify the clonal diversity of isolates.Results: Out of the 87 isolates, 15 (16.6%) formed biofilm. The antibiotic resistance rate was 98.85% for clindamycin, 98.85% for tetracycline, followed by 29.88% for erythromycin, 9.19% for moxifloxacin and 6.89% for levofloxacin. The PFGE patterns revealed a total of 16 different clusters consisting of 6 single types (STs). Conclusion: This study evaluated the biofilm formation of clinical , which may be a step towards understanding its role in pathological processes. Biofilm formation was significant only in the hypervirulent ST-17 clone. Intraclonal spread of isolates indicates that a local lineage of isolates is responsible for infection by these bacteria.

Background and objectives: , and are a group of ded-Spectrum Beta-Lactamase enzymes (ESBLs) which are able to hydrolyze Penicillins and some cephalosporin antibiotics. The present study evaluated the frequency of ESBL genes , and in strains isolated from nosocomial infections to outline the importance of these genes in antibiotic resistance.Methods: One hundred strains were isolated from different nosocomial infections. After antibiotic resistance evaluation with the Kirby-Bauer disc-diffusion method, the Minimum Inhibitory Concentration (MIC) of Ciprofloxacin was measured using the E-test method. Then, the ESBL producing strains were identified employing Combined Disk Methods. Finally, all isolates were evaluated with the Polymerase Chain Reaction (PCR) technique to detect the ESBL genes of interest.Results: Out of 100 isolates, 59% were ESBL positive according to the phenotypic method. The PCR assay could not detect the and genes in the studied isolates, but the presence of gene was demonstrated in 42% of the strains.Conclusion: The high resistance to most antibiotics, the high prevalence of ESBLs-producing strains and also a high prevalence of gene in strains found in the current study gives cause for major concern about nosocomial infections in Iran because of the treatment complexity of these strains. Our results highlight the need for infection control measures to prevent the spread of resistant isolates, especially in hospitals.

Anthelmintic resistance has reached alarming levels worldwide and already seriously threatens pasture-based small ruminant production in certain geographic regions. The situation in Europe has also dramatically deteriorated in the last decade. This review provides an overview of the occurrence of anthelmintic resistance in small ruminants with a particular focus on Germany and its neighbouring countries. It also covers mechanisms leading to the development and spread of anthelmintic resistance, and recommendations for a responsible use of anthelmintics in veterinary practice., Competing Interests: Die Autoren bestätigen, dass kein Interessenkonflikt besteht.Dieser Artikel ist dem Andenken an Dr. Heinz Strobel gewidmet, einem geschätzten Kollegen und Freund, dem die Schäferei und die Schafgesundheit eine Herzensangelegenheit waren., (Thieme.

Background: Because of the rise in primary implantations in elective knee and hip arthroplasty, the number of complications, particularly due to prosthetic infections has increased. Partly due to multimorbidities, an increase in geriatric patients and often unnecessary use of antibiotics, a change in the spectrum of bacteria with an increase in multi-drug resistant pathogens is to be expected. For physicians this creates not only new medical and economic but also sociopolitical challenges. Question: Has the spectrum of bacteria in prosthetic joint infections after total hip arthroplasty (THA) and total knee arthroplasty (TKA) changed during the 12-year period 2001-2012 in our hospital and what role do multi-drug resistant bacteria play? Investigation collective: A total of 320 patients with prosthetic joint infections (PJI) following TKA or THA could be identified and were included in this study. The sample consisted of 172 patients with an infection after THA (56 % females n = 96 and 44 % males n = 76) with a mean age of 70.9 years (range 39-92 years) and 148 patients with an infection after TKA (55 % females n = 82 and 45 % males n = 66) with a mean age of 70.7 years (range 15-87 years). The bacteria detected and the development over the course of time were evaluated. Results: An increase was found in the occurrence of coagulase negative staphylococci (CNS), in particular Staphylococcus epidermidis (2001-2003 n = 10 and 2010-2012 n = 27). The proportion of oxacillin and methicillin-resistant Staphylococcus epidermidis (MRSE) was also found to increase (0 % in 2001-2003 and 74 % in 2010-2012). A substantial increase in methicillin-resistant Staphylococcus aureus (MRSA) infections could not be found and there was a tendency towards reduction in the total number of Staphylococcus aureus infections. A total of five extended spectrum beta-lactamase (ESBL)-producing bacteria were isolated. Conclusion: The spectrum of bacteria has only slightly changed over the years from 2001 to 2012, whereby an increase was only found in the number of CNS infections. Multi-drug resistant bacteria, in particular MRSE have increased. The changes in MRSE found in this study do not appear to warrant a general rethinking of antibiotic prophylaxis.

Background: Serious infections resulting from seemingly harmless wounds are often difficult to predict. Objectives: We sought to identify often underestimated injuries of the hand and associated factors which may help to reliably predict the risk of infection. Materials and methods: A literature review was conducted to identify the risk of infections in small and superficial injuries of the hand as well as specific forms of injuries that are frequently underestimated. Reflecting the most recent literature, we discuss the risks of infection and seemingly harmless injury patterns that require prompt surgical intervention. Results: Early and adequate surgical debridement is highly recommended when minor signs of infection are present in susceptible patients or wounds, in case of foreign body injuries and bite injuries or in any high-pressure injection injury. Follow-up examinations at regular intervals are necessary to verify that immune response is strong enough to eliminate foreign invaders before their populations grow beyond control, mandating surgical intervention. Antibiotic treatment only is inadequate for encapsulated infections or foreign body injuries. However, it may dissimulate symptoms which would otherwise have led to consideration of surgical debridement and, therefore, delays appropriate treatment and may increase the risk of development of drug resistance. Conclusion: Surgical debridement should not be delayed when minor signs of infection are present in susceptible patients or in specific patterns of injury of the hand. [ABSTRACT FROM AUTHOR]

Organometallic ruthenium compounds that are effective anticancer and antimetastasis agents are currently under intensive investigation (see also the article by Peter Sadler in this issue). This article provides a personal account of the way in which we have exploited the different properties of the organoruthenium (and osmium and rhodium) compounds to rival traditional DNA-binding platinum drugs, culminating in the discovery of a non-classical molecule that is in an advanced stage of pre-clinical evaluation.

Background: Ibrutinib improves the treatment of relapsed or refractory mantle cell lymphoma, a mature B cell neoplasm. However, relapses following treatment with this Bruton tyrosine kinase inhibitor occur frequently, and the outcome of affected patients is poor., Objectives: Single-cell RNA sequencing (scRNA-seq) can track trends in gene expression of mantle cell lymphoma cells across ibrutinib treatment and new therapeutic targets can be defined based on the detected resistance mechanisms., Materials and Methods: The ibrutinib-sensitive mantle cell lymphoma cell line REC‑1 was treated with ibrutinib for 6 h and 48 h. Droplet-based scRNA-seq was performed to examine the transcriptomic alterations of surviving cells using the 10× Genomics platform. Extracellular flux analysis and flow cytometry were applied to further study the observed adaptations to ibrutinib treatment., Results: REC‑1 harbored a subpopulation with potential for crosstalk with microenvironment and therefore greater risk for aggressiveness and drug resistance. Following ibrutinib treatment, NF-κB signaling was turned off. In contrast, the cells upregulated B-cell receptor genes and surface antigens such as CD52, and switched their metabolism to increased dependence on oxidative phosphorylation., Conclusions: Targeting oxidative phosphorylation or CD52 in combination with or as follow-up to ibrutinib might overcome resistance and provide improved prognosis for mantle cell lymphoma patients., (© 2022.

Resistant hypertension is defined as blood pressure that remains above therapeutic goal despite the use of 3 antihypertensive drugs including a diuretic. After exclusion of secondary causes and medical incompliance, the estimated prevalence of resistant arterial hypertension ranges from 4% to 19% in hypertensive patients. Treatment requires a multimodal therapeutic approach. Hyperactivation of the sympathetic nervous system plays a key role in the genesis of hypertension. Targeting renal sympathetic nerves, percutaneous catheter-based renal denervation is a new therapeutic option for the treatment of resistant arterial hypertension in selected drug resistant patients.

New therapeutics for the treatment of chronic kidney disease and secondary hyperparathyroidism, such as calcium and aluminium-free phosphate binders, calcimimetic agents and active vitamin D metabolites may decrease the need for parathyroidectomy. The calcimimetic cinacalcet does not induce a longer lasting regression of renal hyperparathyroidism and autonomous growing of parathyroids and the therapeutic effect is limited to the period of treatment. The classical indications for surgery, hypercalcemia, vascular calcification, severe osteopathy, drug-resistant hyperphosphatemia and calciphylaxis are still valid if patients do not respond to medical therapy under the condition that adynamic bone disease is excluded. Individual operative risk factors and improvement of quality of life are important supplementary factors for the indication for parathyroidectomy. [ABSTRACT FROM AUTHOR]

Rational outpatient therapy restricts antibiotics to infections where they are beneficial and selects substances based on local resistance patterns. Respiratory tract infections typically caused by viruses should not be treated with antibiotics (e.g., rhinitis, bronchitis, sinusitis). Many respiratory infections likely caused by bacteria can be treated with aminopenicillin, sometimes combined with a beta-lactamase inhibitor. Quinolones should be used only as exception for respiratory tract infections, since resistance is rising. For this reason uncomplicated urinary tract infections (cystitis) should be treated with trimethoprim-sulfamethoxazole (TMP-SMX) instead of quinolones, even though -20% of Escherichia coli are resistant to TMP-SMX. Skin and soft tissue infections are best treated with beta-lactame antibiotics, as long as the community acquired methicillin-resistant strains of S. aureus frequently seen in certain countries remain uncommon here.

Neuropathic pain, caused by various central and peripheral nerve disorders, is especially problematic because of its severity, chronicity, and resistance to simple analgesics. Pathophysiologic changes responsible for generating pain following nerve lesions are usually independent of the etiology of the primary neuronal damage. Several fundamental mechanisms could be identified as principle conditions in the development of neuropathic pain; they include peripheral and central sensitization, disinhibition, sympathetically maintained pain, and cortical reorganization. Classifying neuropathic pain by these basic mechanisms is considered appropriate for basing new treatment approaches. In coming years, several advances are expected in the basic and clinical sciences of neuropathic pain which will provide new and improved therapies for patients continuing to experience this sometimes very disabling condition.
