In single-cell RNA-sequencing, LGR5+ ISC-enriched cell cluster showed strong expression of TNFRSF1B (TNFR2) and Cox-PGE2 activation. In TNFα-treated CD patient-derived enteroids, exogenous PGE2 (10 nM) induced the expansion of the LGR5+ ISC population and improved organoid-forming efficiency, viability, and wound healing.

TNFα increases necroptosis of differentiated cells and induces the expansion of LGR5+ ISCs. In CD patient-derived enteroids, TNFα causes LGR5+ stem cell dysfunction (expansion failure) and exogenous PGE2 treatment restored the functions of LGR5+ stem cells. Therefore, PGE2 can be used to promote mucosal healing in patients with CD.

Dysuria, stranguria, pollakiuria and overflow incontinence developed 2 weeks prior to presentation, while vomiting, polydipsia and anorexia were seen a few days prior to admission. Physical examination revealed prostatomegaly. Biochemistry results were compatible with postrenal azotemia. Abdominal imaging confirmed prostatomegaly with consequent urethral obstruction, and ultrasound-guided fine needle aspiration cytology of the prostate gland was consistent with granulomatous inflammation. The dog was hospitalized, urethral patency was preserved and upon laparotomy a cystostomy tube was placed, and prostatic biopsy was obtained. Orchiectomy was also performed. Urine culture performed two days prior to the surgery was negative. Prostatic histopathology revealed mild to moderate lymphoplasmacytic prostatitis. Three months postoperatively, clinical signs had resolved completely and urinations remained normal while the dog is still in good health three years after diagnosis. This is the first case of canine lymphoplasmacytic prostatitis in which clinical signs, diagnostic evaluation, management and long-term follow up are available.Candidiasis is a fungal infection caused by Candida species which has been reported in most domestic and wild birds and mammals. In this study, 196 samples from different species of birds with suspected symptoms of candidiasis were examined. Pharyngeal swabs, cloacal swabs, and fecal samples were taken from the birds. The samples were cultured in sabouraud dextrose agar (SDA) containing cycloheximide and chloramphenicol and incubated at 42°C. Suspected isolates of Candida were identified using PCR. To detect the candida genus, a primer set to target the candida rDNA (ITS1-ITS4) was selected. To detect Candida albicans (C. albicans), a primer set to target cytochrome P-450 lanosterol-a-demethylase (P450-LIAl) gene (DH-1558) was selected. In direct microscopic observation and culture, 28.57% of the birds were suspected of candidiasis. In the molecular study, candidiasis was confirmed in 25% of the birds, and candidiasis caused by C. albicans was confirmed in 14.28% of the birds. All isolates were subjected to antibiotic susceptibility by the disk diffusion method with glucose-enriched Mueller-Hinton Agar. 78.5% of the isolates were sensitive to nystatin and amphotericin B. None of the isolates were sensitive to itraconazole and more than 50% of the isolates were resistant to fluconazole, ketoconazole, and itraconazole. According to the results, it is suggested to use nystatin and amphotericin B in the treatment of avian candidiasis in the Ahvaz region. To the authors' knowledge, this is the first report of the molecular detection and antifungal susceptibility pattern of C. albicans and non- albicans from Galliformes, Anseriformes, Psittaciformes, and Passeriformes in Iran.Infertility treatments have benefited millions of couples to have their own children, but resultant multiple pregnancies with their increased morbidity and mortality have been a significant complication. Fetal reduction (FR) was developed to ameliorate those. Over 30 years of publications show that FR has been highly successful in substantially reducing both mortality and morbidity. As with most radically new techniques, initial cases were in the "nothing to lose" category. With experience, indications liberalize, and quality of life issues increase as a proportion of cases. Overall risks for twins are not twice singletons; they are about 4 - 5 x higher. In experienced hands, the combination of genetic testing by CVS followed by FR has made most multiples behave statistically as if they were originally the lower number. Use of microarray analysis to better determine fetal genetic health before deciding on which fetus(es) to keep or reduce further improves pediatric outcomes. With increasing experience and lower average starting numbers, the proportion of FRs to a singleton has increased considerably. Twins to a singleton FR now constitute an increasing proportion of cases performed. Data on such cases show improved outcomes, and we believe FR should be at least discussed and offered to all patients with a dichorionic twin pregnancy or higher. With increasing reliance upon elective single embryo transfer (eSET), monochorionic twins have substantially increased which have much higher complication rates than dichorionic twins. Furthermore, monochorionic twins cannot be readily, safely reduced so the adverse perinatal statistics of eSET are a major set-back for good outcomes. While eSET is appropriate for some, we believe that for many couples, transfer of 2 embryos is generally a more rational approach.

To determine whether ART is associated with a higher risk of preterm deliveries in twin gestations compared with non-exposure to ART.

This is a secondary analysis of a randomized, double-blinded, placebo-controlled trial of weekly progesterone to prevent preterm delivery in twin gestations. For our analysis, all subjects with twin gestations and known gestational age at delivery were included. Women were excluded if they had intrauterine insemination or congenital fetal anomalies. Our primary exposure was ART, defined as IVF and ICSI. Subjects non-exposed to ART either had spontaneous conceptions or were conceived with ovarian stimulation. Our primary outcome was preterm delivery, defined as delivery prior to 35 weeks gestation. Secondary outcomes included spontaneous or indicated preterm delivery less than 35 weeks.

Of the 1261 subjects, 309 (24.5%) had ART, and 952 (75.5%) were not exposed to ART. Women exposed to ART were more likely to be white, older, and have dichorionic twins, and they were less likely to be smokers. The groups had similar rates of prior preterm births. The rates of overall PTB (40.8% v. 39.3%, p=0.642) and spontaneous PTB (20.8% v. 24.1%, p=0.221) were similar. After adjusting for confounders, ART exposure was not related to any preterm birth category, and the strongest predictors for spontaneous preterm birth was a prior preterm birth (aOR 3.38, 95% CI 2.04-5.59, p=<0.0001) and Black race (aOR 1.61, 95% CI 1.06-2.45, p=0.026).

In our cohort of twin pregnancies, ART was not an independent risk factor for preterm birth.

At gross examination, the placenta showed a diffuse marbled appearance and a focal hemorrhagic area. Multiple areas of hemorrhagic/ischemic necrosis with central and peripheral villous infarctions and thrombosis of several maternal and fetal vessels with luminal fibrin and platelet deposition was observed. All the lesions appeared to be synchronous. Virus particles were identified by Electron Microscopy within the cytoplasm of endothelial cells whereas, by real time rRT-PCR assay, SARS-CoV-2 RNA was detected in placental tissue. In this case, fetal vascular malperfusion was likely casually associated with the infection; indeed, our EM images clearly showed that the marked SARS-CoV-2 endotheliotropism involved the intravillous fetal capillaries. We confirmed that syncytiotrophoblast is the major target cell type for SARS-CoV-2 infection of the placenta. In conclusion, the possible consequences of the action of the placentotropic SARS-CoV-2 include the occurrence of vertical transmission, as reported in literature, and/or stillbirth this latter possibility may be triggered by a hampered maternal and/or fetal perfusion of the placenta. The diffuse thrombosis and subsequent ischemia of fetal capillaries induced by COVID-19 cannot be predicted by standard clinical surveillance.Operative repair of flexor tendons after traumatic injury may be performed under general anesthesia (GA), regional blocks, or a wide-awake local anesthesia no tourniquet (WALANT) technique. To our knowledge there are currently no large-scale reports evaluating outcomes of flexor tendon repair in patients where wide-awake anesthesia was utilized in comparison to regional anesthesia (RA) and general anesthesia. We performed a retrospective analysis of patients who underwent treatment for flexor tendon injuries at a tertiary referral center for hand surgery over a two-year period. A total of 151 patients were included (53 WALANT, 57 RA, and 41 GA) and a total of 251 tendons were repaired (63 WALANT, 104 RA and 84 GA). No statistically significant difference was observed in rates of tendon rupture, adhesions, infection, or hand function. Flexor tendon repair under WALANT is found to be safe and presents comparable operative and functional outcomes to more traditional anesthetic techniques. Additional advantages, including the ability to test the repair intraoperatively, patient education, and the potential for boosting theatre efficiency. Further studies, preferably utilizing a randomized trial methodology, may further elucidate the benefits and risks of WALANT versus regional and general anesthesia.The silkworm (Bombyx mori) is a domesticated and economically important insect. During the whole growth period, silkworm suffers various pathogen infection. Nearly 80% of silk cocoon crop losses are attributed to viral diseases. The circular double-stranded DNA virus Bombyx mori nuclepolyhedrovirus (BmNPV) is the major viral pathogen responsible for massive silkworm death and huge economic losses in the sericulture industry. Up to now, almost all the new strategies for developing immunity against BmNPV are in laboratory strains because of the lack of transgenic technology in industrial silkworm strains. We previously demonstrated that modification of BmNPV genome DNA with the antivirus transgenic CRISPR/Cas9 system effectively improved the resistance of laboratory silkworm strains to viral pathogens. The industrial strains are monovoltine or bivoltine. It is very difficult to break the diapause before microinjection for genetic transformation. Here, we show that the anti-BmNPV transgenic CRISPR/Cas9 system also works in the industrial silkworm strain Jingsong. Sapanisertib In this study, we successfully broke diapause and obtained generation-skipping embryos and constructed two TG Jingsong lines. Both lines exhibited significantly enhanced immunity to BmNPV without significant changes in most of the commercially important traits. These results demonstrate that the construction of TG silkworm lines carrying a heritable immune defense system against BmNPV could be an effective strategy to enhance the resistance of industrial silkworm strains to the most devastating DNA virus. The research opened a window for genetic modification of the important strains from laboratory strains to industrial strains.
