BACKGROUND
Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFAs) seem to be increasing rapidly worldwide. However, nationwide studies have been limited to food-protein-induced enterocolitis (FPIES) and food-protein-induced allergic proctocolitis (FPIAP), with little attention to other non-IgE-GIFA subgroups. The aim of this study was to elucidate the clinical features of all patients with non-IgE-GIFAs, not just certain subgroups.
METHODS
We conducted a nationwide cross-sectional survey of non-IgE-GIFAs in Japan from April 2015 through March 2016. A questionnaire was sent to hospitals and clinics throughout Japan. The questionnaire asked about the number of physician-diagnosed non-IgE-GIFA patients, the status of fulfillment of the diagnostic criteria, tentative classification into 4 clusters based on the initial symptoms, the day of onset after birth, complications, and the suspected offending food(s).
RESULTS
The response rate to that questionnaire was 67.6% from hospitals and 47.4% from clinics. Analyses were conducted about "diagnosis-probable" patient cohort (n = 402) and the "diagnosis-confirmed" patients (n = 80). In half of the reported non-IgE-GIFA patients, onset occurred in the neonatal period. The patients were evenly distributed among 4 non-IgE-GIFA clusters. In Cluster 1, with symptoms of vomiting and bloody stool, the onset showed a median of 7 days after birth, which was the earliest among the clusters. Cow's milk was the most common causative food.
CONCLUSIONS
In half of the patients, the onset of non-IgE-GIFAs was in the neonatal period. This highlights the importance of studying the pathogenesis in the fetal and neonatal periods.

INTRODUCTION
Although the efficacy of 5-aminosalicylic acid (ASA) suppositories for ulcerative colitis (UC) has been reported in many studies, many studies have also described poor adherence to 5-ASA suppository regimens. We aimed to identify the clinical background factors that influence adherence to 5-ASA suppositories to improve adherence and efficacy of the treatment.
METHODS
We conducted a retrospective cohort study of 61 patients with active UC who were using 5-ASA suppositories. All patients underwent endoscopy and rectal biopsy for histological diagnosis prior to 5-ASA suppository treatment. The efficacy of 5-ASA suppository treatment was compared in relation to clinical background factors (sex, age, disease duration, disease type, clinical activity, Ulcerative Colitis Endoscopic Index of Severity, histological activity, serum C-reactive protein level, concomitant use of immunomodulators, history of steroid use, and dose of oral 5-ASA).
RESULTS
The efficacy of 5-ASA suppositories was significantly related to low Lichtiger Colitis Activity Index (LCAI) scores and proctitis type prior to its use. In terms of sex, females tended to show higher efficacy. Multivariate logistic regression analysis using these three factors showed high predictive value for the efficacy of 5-ASA suppositories (AUC, 0.788; sensitivity, 87.2%; and specificity, 63.7%).
CONCLUSION
This study is the first to extract clinical background factors for predicting the efficacy of 5-ASA suppositories. The use of 5-ASA suppositories in patients who are expected to show efficacy will be effective in improving patient co-operation.

Acute severe ulcerative colitis (ASUC) is an emergent medical condition and particularly challenging to treat efficaciously. Infliximab is one of the medical salvage treatment options after corticosteroid refractoriness, but the best induction strategy is not yet defined. With this case series, the authors intend to describe three corticosteroid-refractory ASUC cases with different intensified/accelerated infliximab induction approaches and review the literature on this topic. The first case describes an 18-year-old girl with ASUC at disease onset with rapid progression to toxic megacolon, complicated also with anemia, hypoalbuminemia, and coagulopathy. After corticosteroid failure, both accelerated and intensified (10 mg/kg) infliximab regimen was completed within 11 days, with solid clinical response and colon imaging normalization. Second, we present a 26-year-old male with left-sided ulcerative colitis known for 2 years, under mesalazine, who developed a moderate flare and was started on infliximab after partial and inconsistent response to corticosteroids. During the induction period, he presented this time an ASUC episode, which motivated an early and intensified third dose with good clinical response. Finally, we describe the case of a 78-year-old man with ulcerative proctitis for 12 years presenting ASUC with proximal disease extension as well. After unsatisfactory response to corticosteroids, infliximab was initiated on an accelerated induction regimen, completed in 13 days, with the standard dose, achieving clinical remission. Accelerated or intensified infliximab induction plans are becoming current clinical practice in corticosteroid-refractory ASUC. Current guidelines refer to the possibility of this type of strategies, not determining the optimal regimen due to lack of solid evidence. Literature is mainly based on retrospective studies, not randomized, with heterogeneous groups according to disease severity, and the effect on colectomy rates, mainly on the long term, is not clear. Additional well-supported studies are needed on this subject in order to seek a more widely uniform approach.

Objective Carcinoma cervix is one of the major cancers affecting Indian women. Concurrent chemo-radiotherapy is the standard of care in the treatment of carcinoma cervix. We aimed to study the outcomes and toxicity profile of volumetric modulated arc therapy (VMAT), an advanced modality of radiation delivery when used to treat patients with carcinoma cervix. Materials and methods Patients of carcinoma cervix belonging to FIGO (The International Federation of Gynecology and Obstetrics) stages IB2- IVA were recruited into the study. The patients were treated with VMAT to an EBRT (External Beam Radiation Therapy) dose of 50.4Gy in 28 fractions, which was followed by a brachytherapy schedule of 8Gy for each fraction to point A for three fractions. Toxicities were monitored weekly during the course of treatment and thereafter at every follow-up visit. A response assessment CECT (Contrast Enhanced Computed Tomography) scan was done three months after treatment and the response was recorded using RECIST (Response Evaluation Criteria In Solid Tumors) criteria. Results Sixty-four patients were available for analysis and most of the patients belonged to stage IIB (50.3%) followed by stage IIIB (28.5%). The complete response rate was 90.6% at three months and at a median follow-up of 12 months, the overall survival was 100% and disease-free survival was 89.1%. An analysis of clinically significant toxicities (grade 2 or worse) showed that diarrhea was the most common (20.3%) followed by proctitis (14%) and anemia (9.3%). Conclusion The results of the study established that volumetric modulated arc therapy is an acceptable modality of treatment of carcinoma cervix with an attractive toxicity profile. However, longer follow-ups will provide valuable information regarding the long-term disease control and late toxicities of the treatment.

OBJECTIVES
This study aimed to analyze characteristics of mpox hospitalization in a Brazilian cohort, further exploring the impact of HIV on mpox-related outcomes and hospitalization.
DESIGN
We conducted a descriptive analysis, comparing characteristics of individuals diagnosed with mpox according to hospitalization and HIV status, and described the mpox cases among those living with HIV.
METHODS
This was a single-center, prospective cohort study conducted at a major infectious diseases referral center in Rio de Janeiro, Brazil, that enrolled participants older than 18 years of age diagnosed with mpox. Information was collected on standardized forms, including data on sociodemographic, behavioral, clinical and laboratory characteristics. For comparisons, we used chi-squared, Fisher's exact and the Moods median tests whenever appropriate.
RESULTS
From June to December, 2022, we enrolled 418 individuals diagnosed with mpox, of whom 52% were people with HIV (PWH). PWH presented more frequently with fever, anogenital lesions and proctitis. The overall hospitalization rate was 10.5% ( n = 43), especially for pain control. Among hospitalized participants, PWH had more proctitis and required invasive support. Mpox severity was related to poor HIV continuum of care outcomes and low CD4 + cell counts. All deaths ( n = 2) occurred in PWH with CD4 + less than 50 cells/μl.
CONCLUSION
HIV-related immunosuppression likely impacts mpox clinical outcomes. This is of special concern in settings of poor adherence and late presentation to care related to socioeconomic inequalities, such as Brazil. The HIV continuum of care must be taken into account when responding to the mpox outbreak.

BACKGROUND AND AIMS
The 2022-mpox outbreak has spread worldwide in a short time. Integrated knowledge of the epidemiology, clinical characteristics, and transmission of mpox are limited. This systematic review of peer-reviewed articles and gray literature was conducted to shed light on the epidemiology, clinical features, and transmission of 2022-mpox outbreak.
METHODS
We identified 45 peer-reviewed manuscripts for data analysis. The standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement and Cochrane Collaboration were followed for conducting the study.
RESULTS
The case number of mpox has increased about 100 times worldwide. About 99% of the cases in 2022 outbreak was from non-endemic regions. Men (70%-98% cases) were mostly infected with homosexual and bisexual behavior (30%-60%). The ages of the infected people ranged between 30 and 40 years. The presence of HIV and sexually transmitted infections among 30%-60% of cases were reported. Human-to-human transmission via direct contact and different body fluids were involved in the majority of the cases (90%-100%). Lesions in genitals, perianal, and anogenital areas were more prevalent. Unusually, pharyngitis (15%-40%) and proctitis (20%-40%) were more common during 2022 outbreak than pre-2022 outbreaks. Brincidofovir is approved for the treatment of smallpox by FDA (USA). Two vaccines, including JYNNEOSTM and ACAM2000®, are approved and used for pre- and post-prophylaxis in cases. About 100% of the cases in non-endemic regions were associated with isolates of IIb clade with a divergence of 0.0018-0.0035. Isolates from B.1 lineage were the most predominant followed by B.1.2 and B.1.10.
CONCLUSION
This study will add integrated knowledge of the epidemiology, clinical features, and transmission of mpox.

BACKGROUND
The THUNDER-2 phase II single institutional trial investigates the benefits of MRI-guided radiotherapy (MRIgRT) in treating locally advanced rectal cancer (LARC). This study focuses on evaluating the impact of escalating radiation therapy dose in non-responder patients using the Early Tumour Regression Index (ERI) for predicting complete response (CR). The trial's primary endpoint is to increase the CR rate in non-responders by 10% and assess the feasibility of the delta radiomics-based MRIgRT predictive model. This interim analysis assesses the feasibility and safety of the proposed MRIgRT dose escalation strategy in terms of acute toxicity (gastrointestinal, genitourinary and haematological) and treatment adherence.
METHODS
Stage cT2-3, N0-2, or cT4 patients with anal sphincter involvement, N0-2a, M0, but without high-risk features were enrolled. MRIgRT treatment consisted of a standard dose of 55 Gy to the Gross Tumor Volume (GTV) and mesorectum, and 45 Gy to the mesorectum and drainage nodes in 25 fractions with concomitant chemotherapy. 0.35 T MRI was used for simulation imaging and daily alignment. ERI was calculated at the 10th fraction. Non-responders with an ERI above 13.1 received intensified dose escalation from the 11th fraction, resulting in a total dose of 60.1 Gy. Acute toxicity was assessed using the CTCAE v.5 scale.
RESULTS
From March 2021 to November 2022, 33 out of the total number of 63 patients to be enrolled (52.4%) were included, with one withdrawal unrelated to treatment. Sixteen patients (50%) underwent dose escalation. Treatment was well tolerated, with only one patient (3.1%) in the standard treatment group experiencing acute Grade 3 diarrhea, proctitis, and cystitis. No significant differences in toxicity were observed between the two groups (p = 0.5463).
CONCLUSIONS
MRIgRT treatment with dose escalation up to 60.1 Gy is well tolerated in LARC patients predicted as non-responders by ERI, confirming the feasibility and safety of this approach. The THUNDER-2 trial's primary and secondary endpoints will be fully analyzed when all planned patients will be enrolled.

BACKGROUND
Although ulcerative proctitis [UP] can dramatically impair quality of life, treatment efficacy has been poorly investigated in UP as it was historically excluded from phase 2/3 randomised controlled trials in ulcerative colitis. Our aim was to assess the effectiveness and safety of tofacitinib for the treatment of UP.
METHODS
We conducted a retrospective, multicentre study in 17 GETAID centres, including consecutive patients with UP treated with tofacitinib. The primary endpoint was steroid-free remission between Week 8 and Week 14, defined as a partial Mayo score of 2 [and no individual subscore above 1]. Secondary outcomes included clinical response and steroid-free remission after induction and at 1 year.
RESULTS
All the 35 enrolled patients previously received anti-tumour necrosis factor [TNF] therapy and 88.6% were exposed to at least two lines of biologics. At baseline, the median partial Mayo score was 7 (intequartile range [IQR] [5.5-7]). After induction [W8-W14], 42.9% and 60.0% of patients achieved steroid-free remission and clinical response, respectively. At 1 year, the steroid-free clinical remission and clinical response rates were 39.4% and 45.5%, respectively, and 51.2% [17/33] were still receiving tofacitinib treatment. Survival without tofacitinib withdrawal was estimated at 50.4% (95% confidence interval [CI] [35.5-71.6]) at 1 year. Only a lower partial Mayo at baseline was independently associated with remission at induction (0dds ratio [OR] = 0.56 for an increase of 1, (95% CI [0.33-0.95], p = 0.03). Five [14.3%] adverse events were reported, with one leading to treatment withdrawal [septic shock secondary to cholecystitis].
CONCLUSION
Tofacitinib may offer a therapeutic option for patients with refractory UP.
