Development and Pilot of an Mpox Severity Scoring System.

Clinical severity scores facilitate comparisons to understand risk factors for severe illness. For the 2022 multinational monkeypox clade IIb virus outbreak, we developed a 7-item Mpox Severity Scoring System (MPOX-SSS) with initial variables refined by data availability and parameter correlation. Application of MPOX-SSS to the first 200 patients diagnosed with mpox revealed higher scores in those treated with tecovirimat, presenting >3 days after symptom onset, and with CD4 counts <200 cells/mm3. For individuals evaluated repeatedly, serial scores were concordant with clinical observations. The pilot MPOX-SSS demonstrated good discrimination, distinguished change over time, and identified higher scores in expected groups.

Severity scoring system to guide transfusion management in pediatric non-deletional HbH.

BACKGROUND: Hemoglobin (Hb) H is generally recognized as mild thalassemia, despite its actual phenotypic diversity. A disease severity scoring system to guide initiation of regular transfusion among severely affected pediatric patients has not previously been reported. METHODS: Patients with HbH were classified into transfusion-dependent thalassemia (TDT) and non-transfusion-dependent thalassemia (NTDT) as a surrogate for disease severity. Alpha-globin genotypes and relevant clinical parameters associated with TDT were identified. Univariate and multiple logistic regression analyses were performed to yield the most suitable severity scoring system. RESULTS: From 246 patients with a median age of 14.3 (interquartile range 9.9-18.4) years initially enrolled into the study, the chance of having severe disease and developing TDT was remarkable only among patients with non-deletional HbH, for whom the scoring system was developed. Univariate and multiple logistic regression analyses resulted in three retained parameters associated with TDT, ß-coefficients of which were used to develop the score. The final scoring system comprised age at diagnosis <2 years (score = 1), spleen size ≥3 cm (score = 1) and Hb at steady-state <7 (score = 4) or 7-8 g/dL (score = 3). A cutoff score ≥4 was associated with severe disease likely requiring regular transfusion (sensitivity 89.3%, specificity 81.4%), given regular transfusion resulted in maintained growth. The scoring system was validated in the second cohort of 77 non-deletional HbH, from which comparable sensitivity and specificity were obtained. CONCLUSION: The newly developed scoring system was practical and helpful to highlight severely affected pediatric non-deletional HbH patients with potential needs of regular transfusion. This can be used as a guide for optimal treatment and disease monitoring in the future.

[Quality of life after severe hand trauma: A review of 36 cases]. / Qualité de vie apres un traumatisme grave de la main : a propos de 36 cas.

OBJECTIVE: Improve the quality of life of patients with severe hand trauma. MATERIALS AND METHOD: A retrospective study was carried out from August, 1st, 2017, to May 31st, 2020, at the emergency department of a private clinic in Abidjan. Were included in this study all patients with severe hand trauma who had undergone emergency surgery with a quality-of-life assessment time of over six months after surgery. The data were reported on a structured and standardized survey form. RESULTS: We analyzed 36 patients, with average age of 38.6 years (min. 8, max. 71 years). The population study was predominantly male with a sex ratio of 17. 92% of patients were right-handed, and in 53% of cases, the trauma involved the dominant hand. 64.2% of the patients were manual workers. In 83.3% of the cases, the patients had no difficulty in writing. Patients had no difficulty in washing or drying their hair 88.9% of the time. Eighty-nine percent of the patients no longer felt pain. The patients didn't feel any weakness in the hand in 72.2% of the cases and in 63.9% of the cases there was no stiffness in the hand. Only 5.6% of the injured felt their health was poor and 83.3% of patients strongly disagree with feeling less valuable, less confident, or even less capable because of the trauma. 72% of patients were incapacitated for work between 5 and 15 weeks. 80.6% of trauma victims had no loss of income, and 88.9% of patients kept their previous jobs. 83.3% of patients did not experience any social discomfort. CONCLUSION: The patients had a good quality of life despite the severity of hand injuries they had due to early and adequate management combined with good physiotherapy.

Is the performance of the international severity scoring system for familial mediterranean fever in children better than other scoring systems?

AIMS: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterised by recurrent episodes of fever and serosal inflammation with elevated acute phase reactants. Assessing the severity of the disease may be useful in identifying colchicine-resistant patients. The aim of this study is to determine the disease severity of FMF patients according to the Pras, Mor, and International Severity Scoring System for Familial Mediterranean Fever (ISSF) scoring systems and to evaluate the consistency of these three systems. METHODS: The medical records of patients with FMF were retrospectively reviewed. Demographic features, family history of FMF, clinical characteristics at disease onset, laboratory features, Mediterranean fever genetic mutations, treatment regimens, and disease courses were recorded. RESULTS: A total of 205 patients (116 girls) were included in the study. The mean age of the patients was 13.3 ± 4.0 years. The Pras, Mor, and ISSF scores were inconsistent with each other, and there was poor fit between them (generalised Kappa: 0.140 ± 0.029; P < .001). In the receiver operating characteristic (ROC) analysis performed by accepting the clinician's opinion as the gold standard, the ISSF was found to be more sensitive and specific than the other two systems. CONCLUSION: Evaluation of disease severity according to the ISSF in paediatric patients is more sensitive and specific than the Pras and Mor scoring systems.

Evaluation of pneumonia severity scoring systems in nursing and healthcare-associated pneumonia for predicting prognosis: A prospective, cohort study.

The usefulness of existing pneumonia severity indices for predicting mortality in nursing and healthcare-associated pneumonia (NHCAP) is unclear. This study compared the usefulness of existing pneumonia severity indices for predicting mortality in NHCAP and community-acquired pneumonia (CAP). Consecutive hospitalized pneumonia patients including NHCAP and CAP patients were prospectively enrolled between October 2010 and November 2017. Admission pneumonia severity was assessed using CURB-65, Pneumonia Severity Index (PSI), A-DROP, Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) severe pneumonia criteria, and I-ROAD. The primary outcome was 30-day mortality. The discriminatory ability of each severity index was evaluated by receiver operating characteristic curve analysis. Overall, 828 patients had NHCAP, and 1330 patients had CAP. Thirty-day mortality was 12.8% and 5.6% in NHCAP and CAP patients, respectively. The area under the curve of PSI (0.717, 95% confidence interval 0.673-0.761) was the highest among all pneumonia severity indices, with significant differences compared with CURB-65 (0.651, 95% confidence interval 0.598-0.705, P = 0.02) and IDSA/ATS severe pneumonia criteria (0.659, 95% confidence interval 0.612-0.707, P = 0.03). The predictive abilities for 30-day mortality of the pneumonia severity indices, excluding PSI and I-ROAD, were significantly inferior for NHCAP than for CAP. PSI may be the most useful pneumonia severity score for predicting mortality in NHCAP. However, the predictive ability for mortality of each pneumonia severity score was worse for NHCAP than for CAP; therefore, the prognostic factors in NHCAP need to be identified for better management of NHCAP patients.

A Brief Telephone Severity Scoring System and Therapeutic Living Centers Solved Acute Hospital-Bed Shortage during the COVID-19 Outbreak in Daegu, Korea.

With the epidemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2, the number of infected patients was rapidly increasing in Daegu, Korea. With a maximum of 741 new patients per day in the city as of February 29, 2020, hospital-bed shortage was a great challenge to the local healthcare system. We developed and applied a remote brief severity scoring system, administered by telephone for assigning priority for hospitalization and arranging for facility isolation ("therapeutic living centers") for the patients starting on February 29, 2020. Fifteen centers were operated for the 3,033 admissions to the COVID-19 therapeutic living centers. Only 81 cases (2.67%) were transferred to hospitals after facility isolation. We think that this brief severity scoring system for COVID-19 worked safely to solve the hospital-bed shortage. Telephone scoring of the severity of disease and therapeutic living centers could be very useful in overcoming the shortage of hospital-beds that occurs during outbreaks of infectious diseases.

Prediction of disease severity in multiple acyl-CoA dehydrogenase deficiency: A retrospective and laboratory cohort study.

Multiple acyl-CoA dehydrogenase deficiency (MADD) is an ultra-rare inborn error of mitochondrial fatty acid oxidation (FAO) and amino acid metabolism. Individual phenotypes and treatment response can vary markedly. We aimed to identify markers that predict MADD phenotypes. We performed a retrospective nationwide cohort study; then developed an MADD-disease severity scoring system (MADD-DS3) based on signs and symptoms with weighed expert opinions; and finally correlated phenotypes and MADD-DS3 scores to FAO flux (oleate and myristate oxidation rates) and acylcarnitine profiles after palmitate loading in fibroblasts. Eighteen patients, diagnosed between 1989 and 2014, were identified. The MADD-DS3 entails enumeration of eight domain scores, which are calculated by averaging the relevant symptom scores. Lifetime MADD-DS3 scores of patients in our cohort ranged from 0 to 29. FAO flux and [U-13 C]C2-, C5-, and [U-13 C]C16-acylcarnitines were identified as key variables that discriminated neonatal from later onset patients (all P < .05) and strongly correlated to MADD-DS3 scores (oleate: r = -.86; myristate: r = -.91; [U-13 C]C2-acylcarnitine: r = -.96; C5-acylcarnitine: r = .97; [U-13 C]C16-acylcarnitine: r = .98, all P < .01). Functional studies in fibroblasts were found to differentiate between neonatal and later onset MADD-patients and were correlated to MADD-DS3 scores. Our data may improve early prediction of disease severity in order to start (preventive) and follow-up treatment appropriately. This is especially relevant in view of the inclusion of MADD in population newborn screening programs.

Exploring Gut Microbiota Composition as an Indicator of Clinical Response to Dietary FODMAP Restriction in Patients with Irritable Bowel Syndrome.

BACKGROUND: A diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) may relieve symptoms of irritable bowel syndrome (IBS). However, nutritional counseling is resource-demanding and not all patients will benefit. AIMS: To explore whether gut microbial composition may identify symptom response to a low-FODMAP diet in patients with IBS. METHODS: Patients were recruited consecutively to participate in a 4-week FODMAP-restricted diet. Response to diet was defined as ≥ 50% decrease in IBS symptom severity scores (IBS-SSS) compared to baseline. Fecal microbiota were analyzed by a commercially available method (the GA-map™ Dysbiosis Test), assessing 54 bacterial markers targeting more than 300 bacteria at different taxonomic levels. RESULTS: Sixty-one patients (54 F; 7 M) were included: 32 (29 F; 3 M) classified as responders and 29 (25 F; 4 M) as non-responders. Ten of the 54 bacterial markers differed significantly between responders and non-responders. Based on median values (used as cutoff) of responders for these 10 bacterial markers, we constructed a Response Index (RI): Each patient was given a point when the value for each selected bacterial marker differed from the cutoff. These points were summed up, giving an RI from 0 to 10. Patients with RI > 3 were 5 times more likely to respond (OR = 5.05, 95% CI [1.58; 16.10]), and the probability to respond was 83.4%, 95% CI [61.2-94%]. CONCLUSIONS: Gut microbial composition, assessed by using a new RI, may constitute a tool to identify patients that are likely to respond to dietary FODMAP restriction.

Feasibility of the modified sequential organ function assessment score in a resource-constrained setting: a prospective observational study.

BACKGROUND: Sub-Saharan Africa has a great burden of critical illness with limited health care resources. We evaluated the feasibility and utility of the modified Sequential Organ Function Assessment (mSOFA) score in assessing morbidity and mortality in the National Referral Hospital's intensive care unit (ICU) for one year. METHODS: We conducted a prospective, observational cohort study on patients above 12 years of age admitted to the ICU at Mulago Hospital (Kampala, Uganda). All SOFA scores were determined at admission and at 48 h. We modified the SOFA score by replacing the PaO2/FiO2 ratio with SPO2/FiO2. The primary outcome was ICU mortality. RESULTS: This ICU cohort of 118 patients had a mean age of 37 years and an ICU mortality rate of 46.6%. Non-survivors had higher initial (7.7 SD 3.8 vs. 5.5 SD 3.3; p = 0.007), mean (8.1 SD 3.9 vs 4.7 SD 2.6; p < 0.001) and highest mSOFA scores (9.4 SD 4.2 vs. 5.8 SD 3.2; p < 0.001), with an increase of 1.0 (SD 3.1) mSOFA on average after 48 h when compared to survivors (p < 0.001). The area under the receiver operating characteristic curves for each mSOFA category was: initial-0.68, mean-0.76, highest-0.76 and delta mSOFA-0.74. Multivariate logistic regression analysis showed no significant association between mSOFA scores and mortality. CONCLUSION: Our results confirm that calculation of the mSOFA score is feasible for an ICU population in a resource-limited country. More data are needed to test for an association between mSOFA and mortality.

Validation of the anatomic severity score developed by the American Association for the Surgery of Trauma in small bowel obstruction.

BACKGROUND: The anatomic severity schema for small bowel obstruction (SBO) has been described by the American Association for the Surgery of Trauma (AAST). Although acknowledging the importance of physiological and comorbid parameters, these factors were not included in the developed system. Thus, we sought to validate the AAST-SBO scoring system and evaluate the effect of adding patient's physiology and comorbidity on the prediction for the proposed system. METHODS: Patients aged ≥18 y who were treated for SBO at our institution between 2009 and 2012 were identified. The physiology and comorbidity as well as the AAST anatomic scores were determined, squared, and added to calculate the score that we termed Acute General Emergency Surgical Severity-Small Bowel Obstruction (AGESS-SBO). The area under the receiver operating characteristic (AUROC) curve analyses were performed for the AAST anatomic score and compared with the AGESS-SBO score as a predictor for inhospital mortality, extended hospital stay, and inhospital complications. RESULTS: A total of 351 patients with mean age of 66 ± 17 years were identified, of whom 145 (41%) underwent operation to treat bowel obstruction. Extended hospital stay (>9 d) occurred in 86 patients (25%), inhospital complications in 73 (21%), and inhospital mortality in eight patients (2%). The median (interquartile range [IQR]) AAST anatomic score was 1 point (IQR: 1-2), physiology score was 0 point (IQR: 0-1), and comorbidity score was 1 point (IQR: 1-3); for overall median AGESS-SBO score of 5 points (IQR: 3-13). The AUROC curve analyses demonstrated that the AGESS-SBO system with measures of presenting physiology, comorbidities in addition to AAST anatomic criteria could be beneficial in predicting key outcomes including inhospital mortality (AUROC curve: 0.80 versus 0.54, P = 0.03). CONCLUSIONS: The AAST anatomic score is a reliable system, which assists care providers to categorize SBO. Adding physiology and comorbidity parameters to the described anatomic criteria can be helpful in predicting the outcomes including mortality. Further studies evaluating its usefulness in research and quality improvement purposes across institutions are still required.

Utility of severity scoring systems for mangled upper limb salvage: A systematic review and meta-analysis.

BACKGROUND: The purpose of scoring systems is to aid in the decision-making process of whether to salvage or amputate mangled extremities, but their efficacy for upper limbs is uncertain. In this study, we examined the predictive potential of scoring systems for upper limb salvage. METHODS: Two investigators undertook a systematic search of 3 leading databases for English or Japanese literature from 1985, when the first scoring system to evaluate mangled extremities was proposed, until January 2022. To be eligible, studies must have had upper extremity limb salvage or amputation as an outcome, and identified the scoring system used and treatment outcome in individual cases. RESULTS: Ten studies (N = 338) of the Mangled Extremity Scoring System (MESS) were ultimately included in the meta-analysis. The pooled sensitivity and specificity were 0.95 (95 % CI = 0.69-0.99) and 0.81 (0.65-0.91), respectively. The area under the hierarchical summary receiver operating characteristic curve was 0.95 (0.93-0.97). A subgroup analysis showed lower specificity in isolated vascular injuries. Scoring systems other than MESS were ineligible for the quantitative synthesis because none were examined in an adequate number of publications. CONCLUSION: The pooled sensitivity and specificity for MESS were comparable to those reported for the lower extremities. The specificity suggests that limb salvage was achieved in at least 20 % of the patients whose MESS was above the threshold beyond which amputation is indicated. Given the likelihood of upper extremity functional limitations following amputation and the drawbacks of prostheses, we conclude that current scoring systems poorly predict salvageability of a mangled upper extremity and should not be used to justify amputation.

Translation, validation, and first application of the Greek version of an irritable bowel syndrome severity scoring system.

Background: The Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) is a self-administered questionnaire that categorizes patients according to symptom severity. We aimed to translate and adapt the English IBS-SSS, validate the Greek version, and detect factors predictive of IBS severity. Methods: The original English version was obtained from the Rome Foundation, and the final Greek version arose through a process of translation, comprehensibility evaluation and back-translation. The 141 participants enlisted in the study were enrolled from 2 tertiary hospitals and were divided into 2 groups (98 patients and 43 healthy volunteers). We evaluated the questionnaire properties based on COSMIN criteria. Results: The recruited patients reported either diarrhea-predominant (34.7%), constipation-predominant (28.6%), or mixed subtype (36.7%) IBS. No significant variations were found regarding the frequency and intensity of abdominal pain and flatulence among the 3 IBS subtypes. Severity scores among healthy volunteers were significantly lower compared to IBS patients, irrespective of their disease subtype (P<0.001). The Cronbach coefficient (α) was calculated at 0.953, suggesting high inter-item internal consistency. The intraclass correlation coefficient was calculated and found to be high, suggesting good responsiveness of the questionnaire. Two-way MANOVA evaluation showed that demographic variables (age, family status, body mass index [BMI], smoking, and alcohol consumption) in the Greek population affect the IBS-SSS score and syndrome severity. Conclusions: The Greek version of IBS-SSS is a reliable, valid and responsive tool for assessing Greek IBS patients' symptom severity. Older age, smoking, alcohol use and higher BMI are indicative of greater symptom severity.

Severity scoring systems for radiation-induced GI injury - prioritization for use of GI-ARS medical countermeasures.

PURPOSE: Severity scoring systems for ionizing radiation-induced gastrointestinal injury have been used in animal radiation models, human studies involving the use of radiation therapy, and human radiation accidents. Various radiation exposure scenarios (i.e. total body irradiation, total abdominal irradiation, etc.) have been used to investigate ionizing radiation-induced gastrointestinal injury. These radiation-induced gastrointestinal severity scoring systems are based on clinical signs and symptoms and gastrointestinal-specific biomarkers (i.e. citrulline, etc.). In addition, the time course for radiation-induced changes in blood citrulline levels were compared across various animal (i.e. mice, minipigs, Rhesus Macaque, etc.) and human model systems. CONCLUSIONS: A worksheet tool was developed to prioritize individuals with severe life-threatening gastrointestinal acute radiation syndrome, based on the design of the Exposure and Symptom Tool addressing hematopoietic acute radiation syndrome, to rescue individuals from potential gastrointestinal acute radiation syndrome injury. This tool provides a triage diagnostic approach to assist first responders to assess individuals suspected of showing gastrointestinal acute radiation syndrome severity to guide medical management, hence enhancing medical readiness for managing radiological casualties.

Clinical Usefulness of the "MN Criteria" - the Clostridioides difficile Infection Severity Scoring System - in the Japanese Setting.

Objective The severity of Clostridioides difficile infection (CDI) is an important prognostic factor. The "MN criteria," proposed in Japan in 2017, attempted to remedy the shortfalls in the reported guidelines proposed globally to determine CDI severity. We therefore assessed the accuracy of the MN criteria and validated the important factors associated with predicting CDI severity. Methods Sixty-six CDI cases were investigated retrospectively at a Japanese University Hospital from January 2015 to December 2018. The fulminant cases were screened out, and the non-fulminant cases were classified according to their severity stages using the nine variables included in the MN criteria. Clinical events, such as death within 28 days, colectomy, and admission to the intensive care unit, were evaluated. First, the sensitivity and specificity of the MN criteria for predicting clinical events were determined. The relationships between clinical events and the explanatory variables were then evaluated through univariate and multivariate analyses. Results The screening of the fulminant cases and classification of the non-fulminant cases into mild/moderate and severe/super severe cases resulted in a sensitivity of 1.00 and a specificity of 0.89. Univariate and multivariate analyses revealed a significant association of the serum albumin (Alb) level as well as white blood cell (WBC) count with clinical events. Conclusion The findings provide evidence supporting the accuracy of the MN criteria in predicting CDI severity and show that the Alb and WBC are important variables in predicting CDI severity.

Updating cut-off values of severity scoring systems for community-acquired pneumonia to orchestrate more predictive accuracy.

Background: The assessment of severity is crucial in the management of community-acquired pneumonia (CAP). It remains unknown whether updating cut-off values of severity scoring systems orchestrate improvement in predictive accuracy.Methods: 3,212 patients with CAP were recruited to two observational prospective cohort studies. Three bettered scoring systems were derived from the corresponding well-established and extensively used pneumonia-specific severity scoring systems, i.e. pneumonia severity index, minor criteria and CURB-65 (confusion, urea >7 mmol/L, respiratory rate ≥30/min, low blood pressure, and age ≥65 years) score, with the updating cut-off values for tachypnea and low blood pressure. Cronbach α was employed to determine construct validity. Discrimination was valued by calculating the area under the receiver operating characteristic curve (AUROC) and net reclassification improvement (NRI).Results: Respiratory rate ≥22/min and systolic blood pressure ≤100 mm Hg were performed better than respiratory rate ≥30/min and hypotension for predicting mortality in the derivation cohort, respectively (AUROC, 0.823 vs 0.519, 0.688 vs 0.622; NRI, 0.61, 0.13). Bettered scoring systems orchestrated higher convergences, indicated by greater Cronbach α and more decrease in Cronbach α if the updating cut-off values were deleted. The six scoring systems agreed well with one another. Bettered- pneumonia severity index, minor criteria and CURB-65 score showed higher associations with severity and mortality rates and demonstrated greater predictive accuracies for mortality compared with the corresponding original systems (AUROC, 0.939 vs 0.883, 0.909 vs 0.871, 0.913 vs 0.859; NRI, 0.113, 0.076, 0.108; respectively). The validation cohort confirmed a similar pattern.Conclusions: Updating cut-off values of severity scoring systems for CAP orchestrate improvement in predictive accuracy, suggesting that it may facilitate the rationalization of clinical triage decision-making and further reduce mortality. The current studies provide the first known prospective evidence of potential benefit of the updating cut-off values of severity scoring systems for CAP in predictive accuracy.Key messagesUpdating cut-off values were performed better for predicting mortality.Bettered scoring systems orchestrated higher convergences.Bettered scoring systems demonstrated greater predictive accuracies for mortality.

Effectiveness of an amino acid beverage formulation in diarrhea-predominant irritable bowel syndrome: A pragmatic real-world study.

BACKGROUND: Amino-acid based medical foods have shown promise in alleviating symptoms of drug induced gastrointestinal side effects; particularly, diarrhea-predominant symptoms. Irritable bowel syndrome (IBS) is a gastrointestinal disorder that affects up to 9% of people globally, with diarrhea predominant IBS (IBS-D) being the most prevalent subtype. Further trials are needed to explore potential added benefits when integrated into standard care for IBS-D. AIM: To assess the effectiveness of an amino acid-based medical food as an adjunct to standard of care for adults with IBS-D. METHODS: This is a pragmatic, real world, open label, single arm study comparing a 2-week baseline assessment to a 2-week intervention period. One hundred adults, aged 18 to 65 years, with IBS-D, according to Rome IV criteria, were enrolled after completing a 2-week baseline assessment period and received a 2-week supply of an amino acid based medical food which was consumed at home twice daily on top of their standard of care. The primary outcome was an assessment of tolerability after 2-weeks of consumption, while secondary outcomes included changes in stool consistency (Bristol Stool Form Scale), severity of abdominal pain & discomfort, symptoms of urgency, Global Improvement Survey (GIS), and the IBS severity scoring system (IBS-SSS). RESULTS: The test product was well-tolerated as each participant successfully completed the full 14-day trial, and there were no instances of dropouts or discontinuation of the study product reported. Forty percent of participants achieved a 50% or more reduction in the number of days with type 6-7 bowel movements (IBS-D stool consistency responders). Fifty-three percent of participants achieved a clinically meaningful reduction of 30% in mean weekly pain scores, and 55% experienced the same for mean weekly discomfort scores (IBS-D pain and discomfort responders). Participants experienced a mean -109.4 (95% confidence interval: -130.1, -88.8) point reduction on the IBS-SSS and 52% experienced a minimally clinically important difference of > 95 points. An IBS-SSS category shift from severe to moderate or mild occurred in 69% of participants. For functional symptoms, 76% of participants reported symptom relief on the GIS. CONCLUSION: The amino acid-based medical food was well-tolerated, when added to the standard of care, and demonstrated improvements in both overall IBS symptom severity and IBS-D symptoms within just 2 wk.

Development of a Drum Tower Severity Scoring (DTSS) system for pyrrolizidine alkaloid-induced hepatic sinusoidal obstruction syndrome.

BACKGROUND AND AIMS: There has been no reliable severity system based on the prognosis to guide therapeutic strategies for patients with pyrrolizidine alkaloid (PA)-induced hepatic sinusoidal obstruction syndrome (HSOS). We aimed to create a novel Drum Tower Severity Scoring (DTSS) system for these patients to guide therapy. METHODS: 172 Patients with PA-HSOS who received supportive care and anticoagulation therapy in Nanjing Drum Tower Hospital from January 2008 to December 2020 were enrolled and analyzed retrospectively. These patients were randomized into a training or validation set in a 3:1 ratio. Next, we established and validated the newly developed DTSS system. RESULTS: Analysis identified a predictive formula: logit (P) = 0.004 × aspartate aminotransferase (AST, U/L) + 0.019 × total bilirubin (TB, µmol/L) - 0.571 × fibrinogen (FIB, g/L) - 0.093 × peak portal vein velocity (PVV, cm/s) + 1.122. Next, we quantified the above variables to establish the DTSS system. For the training set, the area under the ROC curve (AUC) (n = 127) was 0.787 [95% confidence interval (CI) 0.706-0.868; p < 0.001]. With a lower cut-off value of 6.5, the sensitivity and negative predictive value for predicting no response to supportive care and anticoagulation therapy were 94.7% and 88.0%, respectively. When applying a high cut-off value of 10.5, the specificity was 92.9% and the positive predictive value was 78.3%. For the validation set, the system performed stable with an AUC of 0.808. CONCLUSIONS: The DTSS system can predict the outcome of supportive care and anticoagulation in PA-HSOS patients with satisfactory accuracy by evaluating severity, and may have potential significance for guiding therapy.

Intra-operative gallbladder scoring predicts conversion of laparoscopic to open cholecystectomy: a WSES prospective collaborative study.

Introduction: Laparoscopic cholecystectomy, the gold-standard approach for cholecystectomy, has surprisingly variable outcomes and conversion rates. Only recently has operative grading been reported to define disease severity and few have been validated. This multicentre, multinational study assessed an operative scoring system to assess its ability to predict the need for conversion from laparoscopic to open cholecystectomy. Methods: A prospective, web-based, ethically approved study was established by WSES with a 10-point gallbladder operative scoring system; enrolling patients undergoing elective or emergency laparoscopic cholecystectomy between January 2016 and December 2017. Gallbladder surgery was considered easy if the G10 score < 2, moderate (2 â‰¦ 4), difficult (5 â‰¦ 7) and extreme (8 â‰¦ 10). Demographics about the patients, surgeons and operative procedures, use of cholangiography and conversion rates were recorded. Results: Five hundred four patients, mean age 53.5 (range 18-89), were enrolled by 55 surgeons in 16 countries. Surgery was performed by consultants in 70% and was elective in (56%) with a mean operative time of 78.7 min (range 15-400). The mean G10 score was 3.21, with 22% deemed to have difficult or extreme surgical gallbladders, and 71/504 patients were converted. The G10 score was 2.98 in those completed laparoscopically and 4.65 in the 71/504 (14%) converted. (p <  0.0001; AUC 0.772 (CI 0.719-0.825). The optimal cut-off point of 0.067 (score of 3) was identified in G10 vs conversion to open cholecystectomy. Conversion occurred in 33% of patients with G10 scores of ≥ 5. The four variables statistically predictive of conversion were GB appearance-completely buried GB, impacted stone, bile or pus outside GB and fistula. Conclusion: The G10 operative scores provide simple grading of operative cholecystectomy and are predictive of the need to convert to open cholecystectomy. Broader adaptation and validation may provide a benchmark to understand and improve care and afford more standardisation in global comparisons of care for cholecystectomy.

Disease Severity and Genotype Affect Physical Growth in Children With Familial Mediterranean Fever.

Objectives: This study aims to analyze the growth parameters in children with familial Mediterranean fever (FMF) according to disease characteristics including genotype and disease severity by a recently validated tool in relatively more patients. Patients and methods: This retrospective study included 126 patients with FMF (70 males, 56 females; mean age 7.3±3.6 years; range, 4.1 to 18 years). MEditerranean FeVer (MEFV) gene analysis was performed with a molecular diagnostics tool by using a next-generation sequencing platform. Disease severity was determined for the first visit by the validated tool in children, international severity scoring system for FMF. Growth parameters including weight and height were investigated after standard deviation (SD) scores were calculated by anthropometric references in Turkish children. Results: Median follow-up duration was 74.7 months (range, 7.5 to 169 months). Ninety-three patients (73.8%) had at least one M694V mutation in MEFV gene. Six patients (4.8%) had severe disease, 58 (46%) had intermediate severity, and 62 (49.2%) had mild disease. Mean height SD score was significantly lower at last visit than before colchicine treatment. Initial and last height and weight SD scores were lower in patients with at least one M694V mutation than those without. However, the difference was statistically significant for only initial height SD score. We also found statistically significant lower initial height, final height, and weight SD scores in patients with intermediate severity-severe disease activity than mild disease. Conclusion: We advise physicians to score disease severity prospectively and pay attention to patients with intermediate severity-severe disease to avoid growth disturbances.

Symptom Severity Following Rifaximin and the Probiotic VSL#3 in Patients with Chronic Pelvic Pain Syndrome (Due to Inflammatory Prostatitis) Plus Irritable Bowel Syndrome.

This study investigated the effects of long-term treatment with rifaximin and the probiotic VSL#3 on uro-genital and gastrointestinal symptoms in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) plus diarrhoea-predominant irritable bowel syndrome (D-IBS) compared with patients with D-IBS alone. Eighty-five patients with CP/CPPS (45 with subtype IIIa and 40 with IIIb) plus D-IBS according to the Rome III criteria and an aged-matched control-group of patients with D-IBS alone (n = 75) received rifaximin and VSL#3. The primary endpoints were the response rates of IBS and CP/CPPS symptoms, assessed respectively through Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) and The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI), and performed at the start of therapy (V0) and three months after (V3). In IIIa prostatitis patients, the total NIH-CPSI scores significantly (p < 0.05) decreased from a baseline mean value of 21.2 to 14.5 at V3 , as did all subscales, and in the IIIb the total NIH-CPSI score also significantly decreased (from 17.4 to 15.1). Patients with IBS alone showed no significant differences in NIH-CPSI score. At V3, significantly greater improvement in the IBS-SSS and responder rate were found in IIIa patients. Our results were explained through a better individual response at V3 in IIIa prostatitis of urinary and gastrointestinal symptoms, while mean leukocyte counts on expressed prostate secretion (EPS) after prostate massage significantly lowered only in IIIa cases.
