Nephropathy with Atrasentan (SONAR), NCT01858532.

Atrasentan reduced the relative risk of the primary kidney outcome consistently across baseline UACR and eGFR subgroups. The absolute risk reduction was greater among patients in the lowest eGFR and highest albuminuria category who were at highest baseline risk. Conversely, the relative and absolute risks of heart failure hospitalization were similar across baseline UACR and eGFR subgroups.Clinical Trial registry name and registration number Study of Diabetic Nephropathy with Atrasentan (SONAR), NCT01858532.

Procedure-intense specialties, such as surgery or endoscopy, are a major contributor to the impact of the healthcare sector on the environment. We aimed to measure the amount of waste generated during endoscopic procedures and to understand the impact on waste of changing from reusable to single use endoscopes in the USA.

We conducted a 5-day audit (cross-sectional study) of all endoscopies performed at two US academic medical centres with low and a high endoscopy volume (2000 and 13 000 procedures annually, respectively). We calculated the average disposable waste (excluding waste from reprocessing) generated during one endoscopic procedure to estimate waste of all endoscopic procedures generated in the USA annually (18 million). We further estimated the impact of changing from reusable to single-use endoscopes taking reprocessing waste into account.

278 endoscopies were performed for 243 patients. Each endoscopy generated 2.1 kg of disposable waste (46 L volume). 64% of waste was going to the landfill endoscopes may reduce reprocessing waste but would increase net waste.

Tuft cells residing in the intestinal epithelium have diverse functions. In the small intestine, they provide protection against inflammation, combat against helminth and protist infections, and serve as entry portals for enteroviruses. In the colon, they had been implicated in tumourigenesis. Commitment of intestinal progenitor cells to the tuft cell lineage requires Rho GTPase Cell Division Cycle 42 (CDC42), a Rho GTPase that acts downstream of the epidermal growth factor receptor and wingless-related integration site signalling cascades, and the master transcription factor POU class 2 homeobox 3 (POU2F3). This study investigates how this pathway is regulated by the DEAD box containing RNA binding protein DDX5 in vivo.

We assessed the role of DDX5 in tuft cell specification and function in control and epithelial cell-specific

knockout mice (DDX5

) using transcriptomic approaches.

DDX5

mice harboured a loss of intestinal tuft cell populations, modified microbial repertoire, and altered susceptibilities to ileal inflammation and colonic tumourigenesis. Mechanistically, DDX5 promotes CDC42 protein synthesis through a post-transcriptional mechanism to license tuft cell specification. Importantly, the DDX5-CDC42 axis is parallel but distinct from the known interleukin-13 circuit implicated in tuft cell hyperplasia, and both pathways augment

expression in secretory lineage progenitors. In mature tuft cells, DDX5 not only promotes integrin signalling and microbial responses, it also represses gene programmes involved in membrane transport and lipid metabolism.

RNA binding protein DDX5 directs tuft cell specification and function to regulate microbial repertoire and disease susceptibility in the intestine.

Interventional radiology was unsuccessful initially in accessing the cisterna chyli with conventional methods, yet ethiodized oil was noted at the tip of his right chest tube. The chest tube and its tract were used as an avenue to access the thoracic duct and successfully facilitate its embolization.

Necrotizing enterocolitis remains a leading cause of morbidity and mortality in premature infants. The role of prophylactic probiotics in its prevention is unclear. This study evaluates the effect of routine probiotics on the incidence and severity of necrotizing enterocolitis in infants with very low birth weight in the neonatal intensive care unit.

This retrospective cohort study compared infants cared for at a single institution before and after implementation of routine probiotic administration (2014- 2018). Babies born after July 2016 received probiotics containing

and

daily until 35 weeks corrected gestational age. Baseline characteristics, necrotizing enterocolitis incidence and severity, infections, mortality, and length of stay were compared between groups.

Of the 665 infants included in the study, 310 received probiotics and 355 did not. The 2 groups did not differ with regard to gestational age, birth anthropometrics, mode of delivery, comorbidities, and type of enteral feed. The incidence of necrotizing enterocolitis (Bell's stage 2 of 3) was similar between groups (4% v. 5%,

= 0.35), as was its severity (

= 0.10). In addition, there were no significant differences in mortality and length of stay between the groups. VY-3-135 nmr Significantly fewer infants receiving probiotics developed infections (27% v. 34%,

= 0.046), with the rate of urinary tract infections having the largest reduction.

The routine use of

and

probiotics in infants with very low birth weight did not significantly affect the incidence and severity of necrotizing enterocolitis. However, the use of probiotics was associated with fewer overall infections.

The routine use of Bifidobacterium and Lactobacillus probiotics in infants with very low birth weight did not significantly affect the incidence and severity of necrotizing enterocolitis. However, the use of probiotics was associated with fewer overall infections.Hematuria is not uncommonly seen among children. We describe the case of a 13-year-old boy who was diagnosed with urothelial carcinoma after presenting with persistent gross hematuria for 2 weeks. We highlight the importance of adequate workup for gross hematuria as it is often associated with an underlying pathology that could lead to significant morbidity if left undiagnosed.We present the case of a female teenager who sustained nitrous oxide burns to the medial aspect of both thighs from contact with a nitrous oxide canister being used to fill balloons. There was a delay in presentation as the injury was not initially recognised. These burns were initially assessed as being superficial partial-thickness burns but took a prolonged time to heal despite regular wound care. This was complicated by a lack of adherence to recommended treatment for much of the patient care as well as the patient testing positive for COVID-19 during their management, which prevented surgery and significantly extended time to healing. While small numbers of similar cases have been previously described this is the first reported case outside of the Netherlands and in a child. Being aware of such cases ensures early referral to specialist burn care for appropriate management to give patients the best possible outcome.A 21-year-old woman arrived at the emergency department with dyspnoea, arterial hypotension and abdominal pain after 5 days with a influenza-like syndrome. SARS-CoV-2 was detected by reverse transcription PCR in a nasopharyngeal swab specimen. CT of the chest and abdomen with contrast demonstrated a minimal amount of free intraperitoneal fluid, gallbladder with wall oedema, multiple para-aortic lymph node and interlobular septal thickening with ground glass opacities on the lungs. No pleural effusion or thromboembolism. Early broad-spectrum antibiotics, high-flow nasal cannula and norepinephrine were started. She was successfully treated with intravenous immunoglobulin and pulse corticosteroid therapy with methylprednisolone. The patient was discharged home with complete resolution of her symptoms and returned to her previous health status.The formation of an intraperitoneal pseudocyst as a complication of ventriculoperitoneal shunts is well known. However, the formation of a pseudocyst at the subcutaneous extraperitoneal abdominal space is unusual and likely secondary to the migration of the peritoneal catheter. We present a 53-year-old male who had placement of a ventriculoperitoneal shunt for hydrocephalus secondary to a vestibular schwannoma. Five months later, he presented with an enormously distended abdomen. Investigations showed the peritoneal catheter in the extraperitoneal space within a large right lower quadrant abdominal wall pseudocyst. The patient was taken to the operating theatre, and the shunt was externalised at the original abdominal incision. Approximately 3 L of cerebrospinal fluid were aspirated from the distal peritoneal catheter. After negative cultures, a new peritoneal catheter was placed intraperitoneally at the contralateral lower abdominal quadrant. The contralateral quadrant was utilised to prevent fluid accumulation into the old extraperitoneal cavity.Mandibular fractures are rare in infants, and diagnosis can be easily missed due to the difficulty in obtaining an adequate history and the subtle signs. A high index of suspicion and detailed history taking from the caregiver are mandatory to pick up these cases.There are a plethora of management options that have been reported in dealing with such fractures. They range from conservative management to internal fixation by absorbable plates. While conservative management does not interfere with mandibular growth and teeth development, any surgical intervention can carry this risk. Nevertheless, a severely displaced fracture may need anatomical reduction and fixation to allow early nutrition.This study reports a 3-month-old male infant with a fracture in the mandibular symphysis who underwent reduction of the fracture and circummandibular fixation using immobilisation by an acrylic splint for 4 weeks. His long-term follow-up after 20 months showed adequate dentition with proper healing of the fracture site.We report a case of a generally fit and well 54-year-old man who presented with a 2-day history of worsening left-sided otorrhea, headache, neck stiffness, vomiting and fever on the background of a 7-week history of otitis externa (OE). His condition progressed dramatically as he developed symptoms consistent with acute complete cervical cord syndrome with radiological evidence of skull base osteomyelitis, parapharyngeal, retropharyngeal and paravertebral abscesses and sigmoid sinus thrombus. Ultimately, he made a significant, although not complete, recovery. This case is unique in demonstrating how OE can develop into a potentially life threatening condition. It emphasises the importance of early diagnosis and treatment of OE, the recognition of 'red flag' symptoms and highlights the importance of a multidisciplinary team approach when managing complex complications of OE.We describe the case of a 30-year-old man who presented to our institution with hypoxia and widespread pulmonary infiltrates managed initially as COVID-19 before receiving a new diagnosis of HIV-associated Kaposi sarcoma (KS) with widespread pulmonary and skeletal involvement. Initial differential diagnoses included Pneumocystis jirovecii pneumonia, disseminated mycobacterial infection and bacillary angiomatosis. A bone marrow biopsy showed heavy infiltration by spindle cells, staining strongly positive for human herpes virus-8 (HHV-8) and CD34, suggesting symptomatic, disseminated KS as the unifying diagnosis. The patient commenced cytotoxic therapy with weekly paclitaxel, with a clinical and radiological response. To our knowledge, this case is among the most severe described in the literature, which we discuss, along with how COVID-19 initially hindered developing a therapeutic allegiance with the patient.
