Presence Of Gastrointestinal Symptoms Research Articles

Association between Self-Perception of Chewing, Chewing Behavior, and the Presence of Gastrointestinal Symptoms in Candidates for Bariatric Surgery.

Given the changes in the digestive tract post-bariatric surgery, adapting to a new pattern of eating behavior becomes crucial, with special attention to the specifics of chewing mechanics. This study aimed to investigate the association between self-perception of chewing, chewing behavior, and the presence of gastrointestinal symptoms in preoperative patients undergoing bariatric surgery. Sixty adult candidates for bariatric surgery at a public hospital in Belém (Brazil) were analyzed. Participants predominantly exhibited unilateral chewing patterns (91.6%), a fast chewing rhythm (73.3%), a large food bolus (80%), liquid intake during meals (36.7%), and 41.7% reported that chewing could cause some issue. Significant associations were found between the perception of causing problems and chewing scarcity (p = 0.006), diarrhea (p = 0.004), absence of slow chewing (p = 0.048), and frequent cutting of food with front teeth (p = 0.034). These findings reveal a relationship between the perception of chewing problems and chewing scarcity, presence of diarrhea, and fast chewing.

Type II diabetes mellitus increases the risk of inflammatory bowel disease in a prospective cohort study

Inflammatory bowel disease is a common digestive disorder and diabetes can lead to intestinal dysfunction. Patients with inflammatory bowel disease in combination with diabetes present a higher rate of hospitalization and consumption of medical resources, yet the association between type 2 diabetes and Inflammatory bowel disease remains unknown. We studied 313,008 participants from the UK Biobank, including 5891 patients with type 2 diabetes at baseline. Multivariate Cox proportional risk models were constructed to examine the risks associated with type 2 diabetes and inflammatory bowel disease and its subtypes (Crohn's disease, ulcerative colitis). Potential confounders including sociodemographic, lifestyle, physical body indicators, psychological state, hypertension, and thyroid-related disorders were adjusted. Propensity score matching was also performed to analyze their sensitivity. Of a total of 313,008 participants included in the study, 5891 (1.88 %) were diagnosed with type 2 diabetes mellitus at baseline and 1829 (0.58 %) of the entire cohort developed inflammatory bowel disease during follow-up, with a median follow-up time of 13.72 years. Patients with type 2 diabetes had a higher cumulative risk of inflammatory bowel disease compared to the non-type 2 diabetes population (inflammatory bowel disease: 1.24% vs. 0.57%, p<0.001; Crohn's disease: 0.46% vs. 0.15%, p<0.001; ulcerative colitis: 0.73% vs. 0.35%, p<0.001). Multivariate Cox regression analysis showed that type 2 diabetes was independently associated with inflammatory bowel disease (Hazard Ratio: 1.61 [95% Confidence Interval: 1.26-2.06], p<0.001), Crohn's disease (Hazard Ratio: 2.10 [95% Confidence Interval: 1.39-3.17], p<0.001) and ulcerative colitis (Hazard Ratio: 1.58 [95% Confidence Interval: 1.15-2.18], p=0.005). In a propensity-matched analysis, type 2 diabetes still showed its ability to predict the risk of inflammatory bowel disease (Hazard Ratio: 2.09 [95% Confidence Interval: 1.55-2.83], p<0.001), Crohn's disease (Hazard Ratio: 3.49 [95% Confidence Interval: 2.00 to 6.09], p<0.001), and ulcerative colitis (Hazard Ratio: 1.76 [95% Confidence Interval: 1.20 to 2.56], p=0.003) of robustness. In patients with type 2 diabetes mellitus, the risk of inflammatory bowel disease is higher, and the presence of gastrointestinal symptoms in patients with type 2 diabetes requires vigilance for the possibility of inflammatory bowel disease in clinical practice.

The evaluation of gastrointestinal involvement and nutritional status in systemic sclerosis: identifying risk factors for malnutrition in a cross-sectional study

Aims: Gastrointestinal (GI) involvement is frequently observed in Systemic sclerosis (SSc). Considering the effect of GI involvement on SSc patients, the risk of malnutrition might be increased. The study aimed to evaluate GI involvement and the risk for malnutrition and to demonstrate the relationship between disease-related features and risk factors for malnutrition in SSc patients. &#x0D; Methods: SSc-related clinical features and disease severity evaluated with Physician Global Assessment (PGA) were recorded. Detailed GI symptoms and the impact of GI involvement on patients were assessed with the UCLA SCTC GIT 2.0 questionnaire. Nutritional status was evaluated with Body Mass Index (BMI) and the Malnutritional Universal Screening Tool (MUST).&#x0D; Results: 104 SSc patients were involved in the study. Mean age of patients with SSc was 52.24±12.82 years. GI involvement was found in 85.7% of patients. 76% of patients had GI symptoms. The median BMI of patients was 25.3 (9) kg/m² with 4.8% of patients categorized as underweight. The assessment of risk for malnutrition using MUST showed 74% of patients at low risk, 16% at moderate risk, and 9.6% at high risk. No important association was detected between risk groups for malnutrition and UCLA GIT 2.0 score. A significant association was found between moderate to high risk for malnutrition and dcSSc (OR 3.12, %95 CI:1.26-7.73; P=0.01), the presence of GI symptoms (OR 5.32, %95 CI:1.16-24.36; P=0.03), the decrease in oral aperture (OR 0.35, %95 CI:0.15-0.79; p:0.02), and severity of the disease investigated by PGA score (OR 1.52, %95 CI:1.09-2.13; p=0.01).&#x0D; Conclusion: GI involvement is a common manifestation in SSc patients. Approximately 26% of patients were at moderate to high risk for malnutrition. Several SSc-specific clinical features, including disease severity, the presence of GI symptoms, dcSSc, and a decrease in oral aperture were related to a higher risk for malnutrition.

Factors Associated with Nutritional Risk Assessment in Critically Ill Patients Using the Malnutrition Universal Screening Tool (MUST).

Background: Malnutrition is an underdiagnosed condition that negatively affects the clinical outcomes of patients, being associated with an increased risk of adverse events, increased hospital stay, and higher mortality. Therefore, nutritional assessment is a required and necessary process in patient care. The objective of this study was to identify the factors associated with nutritional risk by applying the Malnutrition Universal Screening Tool (MUST) scale in a population of critically ill patients. Methods: This was an observational, analytical, and retrospective study. Sociodemographic, clinical, hematological, and biochemical variables and their relationship with nutritional risk and mortality were analyzed. Results: Of 630 patients, the leading cause of admission was pathologies of the circulatory and respiratory system (50%); 28.4% were at high nutritional risk; and mortality was 11.6% and associated with nutritional risk, hemoglobin, and plasma urea nitrogen. Conclusions: The presence of gastrointestinal symptoms and the type of nutritional support received during hospitalization could increase the likelihood of presenting a medium/high nutritional risk, while polycythemia reduced this probability. An associative model was found to determine nutritional risk with an adequate specificity and diagnostic validity index.

HLA genotypes associated with gastrointestinal symptoms in patients with spondyloarthritis without inflammatory bowel disease

This study aimed to establish the association between HLA-A, B, DR genotypes and gastrointestinal variables in patients with SpA without inflammatory bowel disease (IBD). Retrospective study of 91 patients with SpA and 401 healthy controls, with typing by Illumina Sequencing/PacBio and LIFECODES HLA-PCR/SSO multiplex sequencing technology. The presence of gastrointestinal symptoms was evaluated by administering a survey, and those who presented 2 or more symptoms were taken for clinical evaluation by rheumatology and gastroenterology, colonoscopy and histopathological study. (Ethics committee approval). The 59,3% of the patients were men, with a mean age of 43,9±11.4 years; 80,2% were classified as ankylosing spondylitis. 14, 28 and 19 genotypes for the HLA-A*, HLA-B* and HLA-DR* loci were identified in both groups, of which a relationship with gastrointestinal symptoms was identified: A*26, A*29 and B*27 were associated to abdominal pain, DRB1*11 and DRB1*16 with abdominal distention, A*30, B*38, DRB1*13 and DRB1*14 with weight loss, B*40 with diarrhea >4 weeks, and presence of mucus in the stools with A*02 and DRB1*11 (p<0.05). Furthermore, the presence of B*15 had a statistical relationship with intolerance to some food, highlighting the B*27 genotype in relation to grains and dairy products, A*23 with grains, vegetables and meats, and B*49 with vegetables and dairy (p<0.05). Regarding the endoscopic variables, macroscopic changes were found in the ileum mucosa related to A*02, B*48, DRB1*14 and the relationship between B*27 and ulcers at this level should be highlighted. Macroscopic changes in the sigmoid colon with B*48 and the rectum with A*30. In microscopic changes, inflammatory alterations of the ileum are mentioned with genotypes DRB1*07, DRB1*13 and DRB1*14, a genotype that is related to changes in the ileum both endoscopically and histologically (p<0.05). These findings indicate a potential genetic predisposition related to HLA genotypes that may increase the likelihood of food intolerance, gastrointestinal symptoms, and even visible and microscopic changes, specifically in the ileal tissue. The study highlights the presence of B*27 and other noteworthy HLA class I and class II genes (such as DRB1*14) in the diverse Colombian population.

Gastrointestinal Manifestations Are Associated with Severe COVID-19 in Children.

Purpose: Although less severe than in adults, children can experience a range of COVID-19 symptoms, from asymptomatic to life-threatening, including respiratory and gastrointestinal symptoms. Medical conditions may also increase the severity of the disease in infected children. Methods: This study was performed at a single center, comparing cases and controls, and involving 253 pediatric patients who had been diagnosed with COVID-19. Two different outcomes were assessed. The first categorized symptomatic individuals who were hospitalized with COVID-19 (hospital) from those who were not (nonhospital). The second categorized admitted individuals who spent at least one day in the intensive care unit (ICU) from those who did not require intensive care (floor). Results: Ninety individuals (36%) had at least one underlying medical condition, the most common being pulmonary disorders, such as asthma (12%), followed by neurodevelopmental disorders (8%), gastrointestinal disorders (6%), and seizure disorders (6%). The hospital group was more likely to have a comorbidity, such as obstructive sleep apnea (OSA), diabetes mellitus, seizure disorder, hypertension, sickle cell disease, neurodevelopmental disorder, and immunocompromising conditions, including cancer, bone marrow transplant, and other immunodeficiencies, compared to the non-hospital group. Abdominal pain was more common in the hospital group. Shortness of breath (SOB) and diarrhea were significantly more common in the ICU group than in the floor group. Conclusions: Early identification of pediatric patients with severe COVID-19 is important to improve outcomes. In our single-center case-control study, we found that the presence of gastrointestinal symptoms on presentation was more commonly associated with severe COVID-19 in children.

Clinical Characteristics and Diagnostic Prediction of Severe Fever with Thrombocytopenia Syndrome and Rickettsiosis in the Co-Endemic Wakayama Prefecture, Japan.

Background and Objectives: The Wakayama prefecture is endemic for two types of tick-borne rickettsioses: Japanese spotted fever (JFS) and scrub typhus (ST). Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne hemorrhagic viral disease with a high mortality rate and is often difficult to differentiate from such rickettsioses. SFTS cases have recently increased in Wakayama prefecture. For early diagnosis, this study aimed to evaluate the clinical characterization of such tick-borne infections in the co-endemic area. Materials and Methods: The study included 64 febrile patients diagnosed with tick-borne infection in Wakayama prefecture between January 2013 and May 2022. Medical records of 19 patients with SFTS and 45 with rickettsiosis (JSF, n = 26; ST, n = 19) were retrospectively examined. The receiver operating curve (ROC) and area under the curve (AUC) were calculated to evaluate potential factors for differentiating SFTS from rickettsiosis. Results: Adults aged ≥70 years were most vulnerable to tick-borne infections (median, 75.5 years; interquartile range, 68.5-84 years). SFTS and rickettsiosis occurred mostly between summer and autumn. However, no significant between-group differences were found in age, sex, and comorbidities; 17 (89%) patients with SFTS, but none of those with rickettsiosis, experienced gastrointestinal symptoms such as vomiting, abdominal pain, and diarrhea. Meanwhile, 43 (96%) patients with rickettsiosis, but none of those with SFTS, developed a skin rash. The AUCs of white blood cells (0.97) and C-reactive protein (CRP) levels (0.98) were very high. Furthermore, the differential diagnosis of SFTS was significantly associated with the presence of gastrointestinal symptoms (AUC 0.95), the absence of a skin rash (AUC 0.98), leukopenia <3.7 × 109/L (AUC 0.95), and low CRP levels < 1.66 mg/dL (AUC 0.98) (p < 0.001 for each factor). Conclusions: Clinical characteristics and standard laboratory parameters can verify the early diagnosis of SFTS in areas where tick-borne infections are endemic.

Endoscopic findings and predictors of gastrointestinal lesions in children with iron deficiency anemia

Iron deficiency anemia (IDA) can be caused by occult gastrointestinal (GI) blood loss; however, the endoscopic findings in children with anemia are unclear. The study aimed to determine the frequency and factors related to lesions in children with IDA undergoing endoscopy. We retrospectively analyzed the clinical and endoscopic findings of children with a laboratory-based diagnosis of IDA. Of 58 patients, 36 (62.1%) had upper GI tract lesions, with erosive gastritis being the most common lesion. Further, 26 patients underwent concomitant colonoscopy, and 12 (46.2%) had lower GI tract lesions. Overall, 44 (75.9%) patients had lesions in either the upper or lower GI tract. Helicobacter pylori infection was detected in 13 patients (22.4%). Patients with lesions found by endoscopy had significantly lower hemoglobin level (8.9 vs. 10.0 g/dL, p = 0.047) and mean corpuscular volume (75.5 vs. 80.9 fL, p = 0.038). The proportion of patients with previous treatment for IDA was also higher in those with lesions on endoscopy. In multivariate analysis, age of ≥10 years (odds ratio [OR], 6.00; 95% confidence Interval [CI], 0.56–10.75) and positive fecal occult blood test (FOBT) findings (OR, 2.25; 95% CI, 0.14–4.52) were factors related to GI lesions. The presence of GI symptoms was not associated with GI lesions. A high proportion of GI lesions were found by endoscopy in children with IDA in this study. Endoscopy should be considered in children with IDA even without GI symptoms, especially in older children, and those with positive FOBT results.

Prevalence of gastrointestinal symptoms in autism spectrum disorder: A meta-analysis

IntroductionA high prevalence of gastrointestinal (GI) symptoms has been described in children and adolescents with autism spectrum disorder (ASD). In addition, there is evidence that presence of GI symptoms is associated to greater severity of ASD. However, the frequency of GI symptoms in children and adolescents with ASD varies widely across studies, and their true prevalence is unknown. Therefore, the objective of this study was to estimate the prevalence of GI symptoms in children and adolescents with ASD. Material and methodWe conducted a meta-analysis following the PRISMA guidelines. We carried out a rapid systematic search for recent clinical and observational studies published from August 2012 in PubMed. The statistical analyses were performed with the software R. ResultsOf 91 potentially eligible articles, only 8 met our inclusion criteria. The prevalence of GI symptoms ranged between 0% and 69%, with an estimated general prevalence of 33% (95% CI, 13%–57%), higher than that reported by a previous meta-analysis for the general paediatric population. This difference is even greater in the specific comparison of studies that applied the paediatric version of the ROME III questionnaire (QPGS-ROME III). ConclusionsThe results confirmed the hypothesis that there is a higher prevalence of functional GI symptoms in paediatric patients with ASD compared to their neurotypical peers.

#6056 NEPHROLOGIC INVOLVEMENT IN A SURGICAL COMPLICATION: WHEN TO SUSPECT A PYELO-DUODENAL FISTULA

Abstract Background and Aims Spontaneous pyeloduodenal fistula is a rare condition occurring primarily after urologic events, in most cases infected kidney stones, pyonephrosis, xanthogranulomatous pyelonephritis, renal tumors, and infected renal cysts, with nowadays 80 cases described. The close relationship between the kidney and the duodenum is a facilitating condition. Method We describe the case of a 78 yo woman admitted in April 2022 for Acute Kidney Injury associated with fever, vomiting, oliguria and metabolic alkalosis. Over the last two years the patient reported recurrent febrile episodes associated with abdominal tenderness and weight loss. Urine cultures showed recurrent bacterial growth and she received antibiotics for recurrent episodes of pyelonephritis and lower urinary tract infections (K. Pneumonie ESBL +, E. Faecalis, P. Mirabilis). She was under nephrologic follow-up with a renal function demonstrating eGFR CKD-EPI of 35-30 ml/min/1.73 m2. In past medical history she reported atrial fibrillation in DOAC, heart failure with preserved ejection fraction, hypertension, previous left occipito-parietal ischemic stroke and right parotid adenoma. On physical examination of the abdomen there was no tenderness, mild pain in the right hypochondrium, Giordano's maneuver mild positive on the right side. Because of the evidence of lithiasis in the right kidney on ultrasound with grade III hydroureteronephrosis, we performed a CT scan with contrast, finding imaging compatible with right pyelonephritis with associated grade IV hydronephrosis, in particular lithiasic formation localized at the level of the right pyelo-ureteral junction (2 × 1cm), with partial involvement of the proximal portion of the ureter, severe calico-pyelic dilatation with overall reduction of the cortico-medullary thickness; diffuse inhomogeneity of the middle and lower thirds of the renal parenchyma, with evidence of some bubbles in contextual areas and inhomogeneity of the perirenal adipose tissue. Reduced nephrographic effect in the post-contrastographic phases and lack of elimination of the contrast in the urographic phase (12 min) were reported. She was started on antibiotics piperacillin-tazobactam and underwent right percutaneous nephrostomy placement. During the procedure we evidenced a communication between the calyx of the right upper calyceal group and an intestinal loop, probably the duodenum (Fig. 1). Results The patient underwent elective laparotomic surgery for right nephrectomy (Fig. 2) and closure of the intestinal fistula with duodenoraffia and omental patch. She was admitted to a post-operative intensive care unit, given comorbidities and the complexity of the operation. She was discharged in 9 days without post-operative complications, with stable renal function. One month after discharge the patient died of pneumonia. Conclusion Pyeloduodenal fistula is an infrequent condition causing occasional or continuous passing of materials between the alimentary canal and urinary tract. The presence of gastrointestinal symptoms and urinary tract alterations may be misinterpreted when occurring. Management of this case required collaboration between several specialists, with particular skills on AKI and CKD, infective complications, interventional radiology and surgical procedures. The outcome was strongly affected by the patient's general condition and comorbidities, with a good short-term outcome but complications on the long-term follow-up. The occurrence of air in the urinary tract is strongly suggestive of communications across the renal pelvis and the gastrointestinal tract. In particular if occurring in the setting of recurrent infections and nephrolithiasis, the diagnosis of pyelo-intestinal fistula should be considered.

Possible gastrointestinal tract involvement in hereditary transthyretin amyloidosis identified by echnitium-99m pyrophosphate scan.

Transthyretin cardiac amyloidosis (ATTR-CA) can be identified through technetium-99m pyrophosphate (Tc-99m PYP) scintigraphy. Gastrointestinal involvement in systemic transthyretin amyloidosis (ATTR-GI) is typically identified through the presence of gastrointestinal symptoms or by screening via endoscopy and/or rectal biopsy. Currently, there is no noninvasive imaging modality for identifying gastrointestinal amyloidosis. In this study, we present a case of a 20-year-old Chinese woman with transthyretin amyloidosis (ATTR) and Phe64Ser mutation. The patient presented with persistent nausea and vomiting, diarrhea and constipation, and poor appetite for 2 years. Tc-99m PYP imaging revealed possible gastrointestinal tract images that coincided with the patient's gastrointestinal symptoms, suggesting the usefulness of Tc-99m PYP scintigraphy as a diagnostic tool for identifying ATTR-GI.

Factors Predictive of Development of Acute Kidney Injury in Patients With COVID-19 in Brunei Darussalam.

Acute kidney injury (AKI) in coronavirus disease 2019 (COVID-19) patients affects their health outcomes. Incidence and outcomes varied in the literature, particularly with different population and epidemiological demographics. Data remain scarce in the Southeast Asia region. We report the incidence, outcomes, pattern, types of AKI, and factors that influence AKI patient outcomes in Brunei Darussalam. All patients (N = 930) with COVID-19 who were admitted to the National Isolation Center (between 7th August 2021 and 30thSeptember 2021) were included in the study. The confirmation of AKI was based on the KDIGO (Kidney Disease Improving Global Outcomes) criteria. The mean age of the patients was 41.9 ± 14.4 years with diabetes mellitus (DM), hypertension (HT), and chronic kidney disease (CKD) accounting for 11.7%, 29.1%, and 4.8% of comorbidities, respectively. Overall, 109 (11.7%) had AKI (KDIGO Stage 1 [67.9%], 2 [13.8%], and 3 [18.3%]), while 75.2% of the cases occurred pre-admission and 26.6% were cases of acute exacerbation of CKD. Univariate analysis identified age (odd ratio [OR] 1.06), male gender (OR 1.63), local nationality (OR 8.03), DM (OR 4.44), HT (OR 5.29), vascular disease (OR 6.08), presence of gastrointestinal symptoms (OR 2.08), antibiotic (OR 3.70) and nephrotoxins exposures (OR 8.57) as significant variables. Multivariate analysis showed age (adjusted OR [AOR] 1.04), male gender (AOR 1.67), gastrointestinal symptoms (AOR 1.61), antibiotic (AOR 2.34), and nephrotoxins exposure (AOR 4.73) as significant. Our study showed that one in nine patients with COVID-19 developed AKI with almost a third having stages 2 and 3 AKI. Older age, male gender, presence of GI symptoms, and antibiotic and nephrotoxin exposures were significantpredictors of AKI. Patients with these factors should be prioritized for admission and treatment. Even though manifestations are generally now less severe, findings from this study can guide the management of COVID-19 as the disease enters the endemic stage. Furthermore, lessons learned from the COVID-19 pandemic will provide useful information and knowledge for future viral outbreaks or pandemics.

Changes in stress intensity associated with gastrointestinal health in students population during the COVID-19 lockdown

Introduction: The COVID-19 pandemic and the restrictions from routine life habits had a tremendous impact on psychological and physical health of youth. It is known that stress, anxiety and depression can be associated with the development of gastrointestinal (GI) symptoms and known to exacerbate present GI symptoms. The pandemic has forced many changes in the behavior of student population such as the studying in an asocial environment. The aim of this study was to examine and quantify the influence of stress onto the quality of life and GI symptoms in the student population in Bosnia and Herzegovina (B&amp;H), before and during the pandemic lockdown. Methods: A total of 279 students from B&amp;H were assessed for their GI and emotional status in pre-COVID period and during the COVID period using validated instruments: GI symptom rating scale (GSRS), Visceral Sensitivity Index, and the Patient Health Questionnaire 15-item Somatic Symptom Severity Scale. Results: The results showed that moderate and severe GI symptoms were more frequently present among student population at the time of the pandemic than in period before pandemic. The most pronounced symptoms were bloating syndrome and abdominal pain syndrome according to the GSRS. Conclusions: We concluded that concern for one’s health and changed way of life are directly related to a worsening of the symptoms of GI disorders in the student population. Further research should go in the direction of early prevention of GI disorders that take root in early youth and later develop into chronic forms.

COVID-19 Patients with Early Gastrointestinal Symptoms Show Persistent Deficits in Specific Attention Subdomains.

Previous studies have shown that COVID-19 inpatients exhibited significant attentional deficits on the day of discharge. However, the presence of gastrointestinal symptoms (GIS) has not been evaluated. Here, we aimed to verify: (1) whether COVID-19 patients with GIS exhibited specific attention deficits; (2) which attention subdomain deficits discriminated patients with GIS and without gastrointestinal symptoms (NGIS) from healthy controls. On admission, the presence of GIS was recorded. Seventy-four physically functional COVID-19 inpatients at discharge and sixty-eight controls underwent a Go/No-go computerized visual attentional test (CVAT). A Multivariate Analysis of Covariance (MANCOVA) was performed to examine group differences in attentional performance. To discriminate which attention subdomain deficits discriminated GIS and NGIS COVID-19 patients from healthy controls, a discriminant analysis was applied using the CVAT variables. The MANCOVA showed a significant overall effect of COVID-19 with GIS on attention performance. The discriminant analysis indicated that the GIS group could be differentiated from the controls by variability of reaction time and omissions errors. The NGIS group could be differentiated from controls by reaction time. Late attention deficits in COVID-19 patients with GIS may reflect a primary problem in the sustained and focused attention subsystems, whereas in NGIS patients the attention problems are related to the intrinsic-alertness subsystem.

Clinical outcome in newborns of perinatally COVID-19 infected women

Objective Maternal COVID-19 infection during pregnancy has been associated with adverse neonatal outcomes, such as prematurity and neonatal morbidity. Those adverse events are mainly attributed to maternal factors, rather than to the neonatal infection itself. Our aim is to add our experience and present the neonatal outcome of neonates born to mothers with perinatal SARS-CoV-2 infection. Methods This is a prospective case-control study with data from two Academic Tertiary Referral Hospitals in Greece. Electronic records of all births from SARS-CoV-2 positive mothers between March 2020 and April 2021 were analyzed. Demographic data, the severity of maternal COVID-19 disease, gestational age (GA), mode of delivery, birth weight (BW), need for resuscitation and/or supplemental oxygen and duration of hospitalization were recorded. A comparison with 2:1 matched neonates according to sex, GA, and BW born to SARS-CoV-2 negative mothers during the same period was performed. Chi-square and Mann–Whitney U test were used for categorical and non-categorical variables respectively. Results A total of eighty-one neonates were born to SARS-CoV-2 positive mothers during this period. Forty-three percent of pregnant mothers were asymptomatic. Median GA and median BW were 38 weeks (Interquantile range (IQR): 36–39 weeks) and 2940 gr (IQR: 2560–3340 gr) respectively. Prematurity was observed in 24.7% of the cases. Only 2 (2.4%) neonates were PCR positive after delivery. SARS-CoV-2 positive women were more likely to undergo Cesarean section. APGAR score at 5 min and the need for resuscitation did not differ between the two groups. In comparison with the control group, neonates born to SARS-CoV-2 positive mothers presented with gastrointestinal symptoms (53.6% vs 5.1%, p-value= <.001) and hospitalization was longer, mostly due to maternal factors. Conclusion In our study neonatal positivity was limited and no vertical transmission was noted. Neonatal outcomes were comparable to the control group. However, the presence of gastrointestinal symptoms in neonates born to PCR-positive women compared to controls needs further investigation.

The prevalence of gastrointestinal symptoms and cobalamin deficiency in patients with chronic urticaria

BackgroundThere is a paucity of studies reporting the presence of systemic symptoms and micronutrient deficiency in patients with chronic urticaria, and these data are lacking in a Canadian population.ObjectiveTo report the prevalence of gastrointestinal symptoms and vitamin B12 (cobalamin) deficiency in a Canadian patient population diagnosed with chronic urticaria.MethodsA retrospective chart review of 100 adult patients with chronic urticaria was conducted. Demographic characteristics, medications, presence of gastrointestinal symptoms, and laboratory findings were abstracted from electronic medical records.ResultsSeventy percent of patients with chronic urticaria reported experiencing gastrointestinal symptoms. The most common symptom identified was gastroesophageal reflux (42%). Vitamin B12 (cobalamin) deficiency, defined as serum vitamin B12 level ≤ 250 pmol/L, was identified in 31.7% of the patients. Among those patients with urticaria and vitamin B12, 68% reported gastrointestinal symptoms.ConclusionsThis is the first study to provide data on the high prevalence of gastrointestinal symptoms and vitamin B12 (cobalamin) deficiency in a Canadian population diagnosed with chronic urticaria. Early recognition and management of systemic symptoms and micronutrient deficiency may lead to a more comprehensive approach to management of these patients.Trial registration Not applicable

Bochdalek hernia presenting gastrointestinal symptoms in late childhood: a case report

Most cases of congenital diaphragmatic hernia (CDH) can be diagnosed based on symptoms of severe respiratory failure during the neonatal period or fetal ultrasonography. However, some rare cases are diagnosed in late childhood or adolescence. In this case report, I describe an 11-year-old male patient diagnosed with late-onset CDH presenting with acute abdominal pain. The patient had recently experienced anorexia, nausea, and vomiting after eating. However, he reported no abdominal pain or past history of trauma. The abdomen was generally convex. All laboratory data were within normal limits. A chest X-ray revealed elevation of the left diaphragm. Chest computed tomography showed a defect in the left diaphragm. Based on the above radiologic findings, emergency surgery was performed after the diagnosis of diaphragmatic hernia. A surgical incision was performed in the left subcostal area. Finally, late-presenting Bochdalek hernia was diagnosed. The operation was completed and no specific findings on chest X-ray were found after surgery. The patient was discharged on the fourth day after surgery. In conclusion, CDH in late childhood or adolescence is rare and has various clinical manifestations. To avoid complications such as strangulation and bowel perforation, emergency surgery may be required. Thus, it is necessary to suspect CDH in children with recurrent gastrointestinal or respiratory symptoms, based on which an accurate diagnosis can be made and successful surgical treatment can be performed.

The conjugacy of the use of synbiotic Maxilac® with the severity and duration of the course of COVID-19 in outpatient treatment

Despite the mass population immunization, the total spread of the COVID-19 pandemic once again made scientists around the world doubt the effectiveness of currently existing methods of prevention and treatment of a novel coronavirus infection. The rationale for a potentially new approach to the preventive therapy of COVID-19 using probiotic bacterial strains was the presence of a bidirectional “gut-lung” axis, which interacts between these organs through transported soluble microbial metabolites in blood. The study aimed to determine the relationship between the correction of the gut microbiota with the polycomponent synbiotic Maxilac® and clinical and laboratory markers of the severity of the new coronavirus infection. During the open-label, prospective, observational study 60 patients with a confirmed diagnosis of COVID-19, a moderate severity and the presence of gastrointestinal symptoms were divided into 2 groups: the 1st performed the outpatient complex standard treatment with the addition of synbiotic, the 2nd - without addition. All patients of group 1 showed positive dynamics of clinical and laboratory indicators of COVID-19 severity, compared with group 2, where 2 patients needed hospitalization due to the aggravation of the course of novel coronavirus infection. A reduction in the duration of clinical symptoms and the duration of outpatient treatment was revealed in a group of patients taking Maxilac®. The dynamics of clinical and laboratory indicators reflecting the course of COVID-19 indicate the effectiveness of symbiotic’s usage as adjuvant therapy and the possibility of recommending its use in the complex treatment of patients with a novel coronavirus infection.

Clinical characteristics of Campylobacter bacteremia: a multicenter retrospective study

Campylobacter species are the pathogens of the intestinal tract, which infrequently cause bacteremia. To reveal the clinical characteristics of Campylobacter bacteremia, we performed a retrospective, multicenter study. Patients diagnosed with Campylobacter bacteremia in three general hospitals in western Japan between 2011 and 2021 were included in the study. Clinical, microbiological, and prognostic data of the patients were obtained from medical records. We stratified the cases into the gastroenteritis (GE) and fever predominant (FP) types by focusing on the presence of gastrointestinal symptoms. Thirty-nine patients (24 men and 15 women) were included, with a median age of 57 years and bimodal distribution between those in their 20 s and the elderly. The proportion of GE and FP types were 21 (53.8%) and 18 (46.2%), respectively. Comparing these two groups, there was no significant difference in patient backgrounds in terms of sex, age, and underlying diseases. Campylobacter jejuni was exclusively identified in the GE type (19 cases, 90.5%), although other species such as Campylobacter fetus and Campylobacter coli were isolated in the FP type as well. Patients with the FP type underwent intravenous antibiotic therapy more frequently (47.6% vs. 88.9%), and their treatment (median: 5 days vs. 13 days) and hospitalization (median: 7 days vs. 21 days) periods were significantly longer. None of the patients died during the hospitalization. In summary, we found that nearly half of the patients with Campylobacter bacteremia presented with fever as a predominant manifestation without gastroenteritis symptoms.
