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 messages Updating cut-off values were performed better for predicting mortality. Bettered scoring systems orchestrated higher convergences. Bettered scoring systems demonstrated greater predictive accuracies for mortality.

Overview and comparison of the clinical scores in hidradenitis suppurativa: A real-life clinical data.

Partly due to its clinical heterogeneity, hidradenitis suppurativa (HS) is difficult to score accurately; illustrated by the large number of disease scores. In 2016, a systematic review by Ingram et al. reported the use of about thirty scores, and since then, this number has increased further. Our aim is twofold: to provide a succinct but detailed narrative review of the scores used to date, and to compare these scores with each other for individual patients. The review of the literature was done among articles in English and French, on Google, Google scholar, Pubmed, ScienceDirect and Cochrane. To illustrate the differences between scores, data from some Belgian patients included in the European Registry for HS were selected. A first series of patients compares the severity of the following scores: Hurley, Hurley Staging refined, three versions of Sartorius score (2003, 2007, 2009), Hidradenitis Suppurativa Physician Global Assessment (HS-PGA), International Hidradenitis Suppurativa Severity Scoring System (IHS4), Severity Assessment of Hidradenitis Suppurativa (SAHS), Hidradenitis Suppurativa Severity Index (HSSI), Acne Inversa Severity Index (AISI), the Static Metascore, and one score that is not specific to HS: Dermatology Life Quality Index (DLQI). A second set of patients illustrates how some scores change over time and with treatment: Hurley, Hurley Staging refined, Sartorius 2003, Sartorius 2007, HS-PGA, IHS4, SAHS, AISI, Hidradenitis Suppurativa Clinical Response (HiSCR), the very new iHS4-55, the Dynamic Metascore, and DLQI. Nineteen scores are detailed in this overview. We illustrate that for some patients, the scores do not predictably and consistently correlate with each other, either in an evaluation of the severity at a time-point t, or in the evaluation of the response to a treatment. Some patients in this cohort may be considered responders according to some scores, but non-responders according to others. The clinical heterogeneity of the disease, represented by its many phenotypes, seems partly to explain this difference. These examples illustrate how the choice of a score can lead to different interpretations of the response to a treatment, or even potentially change the results of a randomized clinical trial.

Prediction of long-term mortality in patients with ischemic stroke based on clinical characteristics on the first day of ICU admission: An easy-to-use nomogram.

This study aimed to establish and validate an easy-to-use nomogram for predicting long-term mortality among ischemic stroke patients. All raw data were obtained from the Medical Information Mart for Intensive Care IV database. Clinical features associated with long-term mortality (1-year mortality) among ischemic stroke patients were identified using least absolute shrinkage and selection operator regression. Then, binary logistic regression was used to construct a nomogram, the discrimination of which was evaluated by the concordance index (C-index), integrated discrimination improvement (IDI), and net reclassification index (NRI). Finally, a calibration curve and decision curve analysis (DCA) were employed to study calibration and net clinical benefit, compared to the Glasgow Coma Scale (GCS) and the commonly used disease severity scoring system. Patients who were identified with ischemic stroke were randomly assigned into developing (n = 1,443) and verification (n = 646) cohorts. The following factors were associated with 1-year mortality among ischemic stroke patients, including age on ICU admission, marital status, underlying dementia, underlying malignant cancer, underlying metastatic solid tumor, heart rate, respiratory rate, oxygen saturation, white blood cells, anion gap, mannitol injection, invasive mechanical ventilation, and GCS. The construction of the nomogram was based on the abovementioned features. The C-index of the nomogram in the developing and verification cohorts was 0.820 and 0.816, respectively. Compared with GCS and the commonly used disease severity scoring system, the IDI and NRI of the constructed nomogram had a statistically positive improvement in predicting long-term mortality in both developing and verification cohorts (all with p < 0.001). The actual mortality was consistent with the predicted mortality in the developing (p = 0.862) and verification (p = 0.568) cohorts. Our nomogram exhibited greater net clinical benefit than GCS and the commonly used disease severity scoring system. This proposed nomogram has good performance in predicting long-term mortality among ischemic stroke patients.

VALIDITY OF THE VIRTUAL SEVERITY SCORING SYSTEM IN PATIENTS WITH KNEE OSTEOARTHRITIS

The Severity Scoring System (SSS) is a guide to interpreting findings across clinical, functional, and radiological findings, used by qualified, specially trained physiotherapists in the advanced practice role in order to provide consistency in determining the severity of the patient's condition and need for surgical consultation. The system has been utilized for over 14 years as a part of standardized assessment and management care and was incorporated into virtual care in 2020 following the pandemic restrictions. The present study examined the validity of the modified SSS in virtual care.Patients who were referred to the Rapid Access Clinic (RAC), were contacted via phone by two experienced advanced practice practitioners (APPs) from May to July 2020, when in-person care was halted due to the pandemic. The virtual interview included taking history, completing self-reported measures for pain and functional ability and reviewing the radiological reports.A total of 63 patients were interviewed (mean age 68, SD=9), 34 (54%) females. Of 63 patients, 33 (52%) were considered a candidate for total knee arthroplasty (TKA). Men and women were comparable in age, P4 and LEFS scores. The TKA candidates had a significantly higher SSS (p&lt;0.0001) and pain scores (p=0.024). The variability of the total SSS score explained by the functional, clinical and radiological components of the tool were 55%, 48% and 4% respectively, highlighting the more important role of patient's clinical history and disability in the total SSS.The virtual SSS is a valid tool in directing patients for surgical management when used by highly trained advanced practice physiotherapists. A large component of the SSS is based on clinical data and patient disability and the APP's skillset rather than severity of pathology found on imaging.

Hidradenitis suppurativa and inflammatory bowel disease in a nested case-control study.

Association between Hidradenitis Suppurativa (HS) and Inflammatory Bowel Disease (IBD) has been suggested. To assess characteristics of HS and IBD in patients with or without concomitant IBD. In a prospective, nested case-control study, each IBD patient with concomitant HS (Case) was retrospectively matched with 4 patients with HS and no IBD (Controls) for gender and age (±5 years).HS was classified according to the Hurley score and the International Hidradenitis Suppurativa Severity Score System (IHS4). Data were expressed as mean (Standard Deviation). Statistical analysis included Student-t Test or Mann-Whitney Test, χ2 test, univariate and multivariate logistic regression. The study population included 125 patients with HS: 25 with IBD, 100 matched Controls with no IBD. IBD group included 19 (76%) Crohn's disease and 6 (24%) Ulcerative Colitis patients. Obesity, familial HS and perianal HS were less frequent in Cases than in Controls (1[4%] vs 25(25%];p=0.02; 1[4%] vs 21(21%];p=0.04; 1[4%] vs 31(31%];p=0.005, respectively).HS was less severe in Cases when assessed by the IHS4 (5.9±4vs 9±6.7;p=0.04).Complete drug-induced response for HS was more frequent in IBD (13[53%] vs28 (28%]; p=0.04). Clinical characteristics of HS and of patients differed between Cases and Controls. Present findings suggest the need to appropriately search and assess skin lesions compatible with HS in IBD.

Disordered eating and eating competence in members of online irritable bowel syndrome support groups.

This study seeks to evaluate eating competence and disordered eating likelihood among members of online support groups for irritable bowel syndrome (IBS) and determine whether eating competence and disordered eating likelihood varies according to IBS symptom severity and subtype. This cross-sectional study is based on an anonymous survey conducted from August to September 2021. Adults with IBS (N = 225) were recruited from online and social media IBS support forums. IBS symptom severity was assessed using the validated IBS Severity Scoring System (IBS-SSS), likelihood of disordered eating was assessed using the validated Eating Attitudes Test (EAT-26), and eating competence was assessed using the validated Satter Eating Competence Inventory (ecSI 2.0™). Multiple linear regression was used to predict EAT-26 total score from IBS-SSS score, age, and IBS subtype. ANOVAs were used to examine the relationships between IBS severity level, IBS subtype, and ecSI 2.0™ total score. Eating competence among the sample was low at 17% while 27% was classified as likely or very likely disordered eating. IBS severity was positively associated with EAT-26 score (p = 0.011) and ecSI 2.0™ score was significantly lower in the severe IBS group compared to the moderate IBS group (p = 0.016). No relationship was detected between IBS subtype and EAT-26 or ecSI 2.0™ scores. IBS severity was positively associated with disordered eating likelihood and negatively associated with eating competence. This sheds light on the importance of assessing eating competence and screening for disordered eating prior to selecting therapies for patients with IBS, particularly in females with severe symptoms.

Comparative Study of Clinical Severity and Biochemical Markers in Pre COVID-19 and COVID-19 Rhino-Orbito Cerebral Mucormycosis

In view of high surge of sinonasal mucormycosis cases after the second wave of covid 19, present study was planned to know and compare the clinical severity of the disease and also to better understand the difference in the biochemical markers during precovid and post covid period. This retrospective observational study included all cases of sinonasal mucormycosis which were treated in our institute from August 2012 to August 2021. Details of these cases were collected from hospital database system. Biochemical parameters included FBS, HbA1C, urine ketone bodies, blood pH and creatinine. Clinical severity score was measured using self-structured severity scoring system. We found that out of 74 cases treated in our hospital 28 cases were in pre covid period while 46 cases belonged to covid 19 period. Higher male predominance was seen during post covid period (76% vs. 60%). Urine ketone bodies were positive in 7% patients in precovid period compared to 26% in post-covid period. FBS and HbA1C were high approximately 80 and 90% patients respectively in both groups. Clinical severity was significantly high in post covid patients. The present study showed that in spite of similar biochemical profile. The severity of mucormycosis was high in covid positive patients. This study shows that Covid-19 is an independent high risk factor in mucormycosis patients.

A Tritordeum-Based Diet for Female Patients with Diarrhea-Predominant Irritable Bowel Syndrome: Effects on Abdominal Bloating and Psychological Symptoms.

Most female patients with irritable bowel syndrome (IBS) complain of abdominal bloating rather than abdominal pain and diarrhea. The higher incidence in women could be due to the so-called dysfunctional gas handling. Since diet seems the most effective and durable strategy for managing IBS symptoms, we aimed to evaluate the effects of a 12 week diet based on a relatively new cereal, Tritordeum (TBD), on gastrointestinal (GI) symptoms, anthropometric and bioelectrical impedance parameters, and psychological profiles in 18 diarrhea-predominant IBS (IBS-D) female patients with abdominal bloating as the dominant symptom. The IBS Severity Scoring System (IBS-SSS), the Symptom Checklist-90 Revised, the Italian version of the 36-Item Short-Form Health Survey, and the IBS-Quality of Life questionnaire were administered. The TBD reduces the IBS-SSS "Intensity of abdominal bloating" with a concomitant improvement in the anthropometric profile. No correlation was found between "Intensity of abdominal bloating" and "Abdominal circumference". Anxiety, depression, somatization, interpersonal sensitivity, and phobic and avoidance manifestations were significantly reduced after TBD. Lastly, anxiety was correlated with "Intensity of abdominal bloating". Overall, these results suggest the possibility of lowering abdominal bloating and improving the psychological profile of female IBS-D patients using a diet based on an alternative grain such as Tritordeum.

Genotype-Phenotype Associations of Children With Familial Mediterranean Fever in a Cohort Consisting of M694V Mutation and Implications for Colchicine-Resistant Disease.

The aim of this study was to investigate the clinical associations of the second allele mutations and the effect of genotype and presenting features on colchicine resistance in children with familial Mediterranean fever (FMF), carrying at least one M694V variant. The medical records of the patients diagnosed with FMF, in whom at least one allele M694V mutation was detected, were reviewed. Patients were grouped according to the genotype as M694V homozygotes, compound heterozygote M694V with an exon 10 mutation, compound heterozygote M694V with a variant of unknown significance (VUS), and M694V heterozygotes. Disease severity was assessed with the International Severity Scoring System for FMF. Among the 141 patients included, homozygote M694V (43.3%) was the most frequent MEFV genotype. Clinical manifestations of FMF at diagnosis were not significantly different according to genotypic alterations except homozygote M694V. Besides, homozygous M694V was associated with a more severe disease, with more frequent comorbidities and colchicine-resistant disease. A lower disease severity score was observed in compound heterozygotes with VUS than in M694V heterozygotes (median 1 vs 2, p = 0.006). Regression analysis revealed that homozygous M694V, arthritis, and frequency of attacks were associated with an increased risk of colchicine-resistant disease. Clinical manifestations of FMF at diagnosis with a M694V allele were predominantly influenced by the M694V rather than the second allele mutations. Although homozygous M694V was associated with the most severe form, the presence of compound heterozygosity with a VUS did not affect disease severity or clinical features. Homozygous M694V confers the highest risk of colchicine-resistant disease.

A DISEASE SEVERITY SCORING SYSTEM IN DOGS WITH CLINICALLY ACUTE PANCREATITIS

The severity of canine acute pancreatitis (AP) is highly variable. Clinically applicable severity scoring algorithms are limited. One-hundred-thirty-four dogs diagnosed with AP and hospitalized between 2009 and 2014 were selected for analysis to develop a severity scoring system. Eleven variables, i.e. age, hemoglobin, red blood cell count, albumin, total bilirubin, blood urea nitrogen, creatinine, phosphorus, potassium, presence of systemic inflammatory response syndrome and oliguria/anuria after rehydration (Day 2 to Day 4) were significantly abnormal and selected by logistic regression to predict the outcome. A scoring system was developed by incorporating weighting factors assigned to each quartile based on the odds ratio integer value. A predictive score is the sum of all weighting factors for each dog. Receiver-operating curve analyses were performed to assess the sensitivity, specificity and optimal cut-off point of the outcome predictions. The scores of 134 dogs after rehydration ranged from 11 to 78 points. The mean score was [Formula: see text], and the median score was 23 points. The optimal cut-off point for outcome prediction of the scoring system was 35.5, with a sensitivity of 96% and a specificity of 89.3%. The mortality was 85.5% with a score of [Formula: see text], whereas 3.8% had a score of [Formula: see text]. Dogs with a score [Formula: see text] all survived. The severity scoring system provides a reliable and clinically applicable method to assess disease severity in dogs with clinically AP at the time point after rehydration.

COVID-19 Chest CT Quantification: Triage and Prognostic Value in Different Ages.

Objective: We evaluated the triage and prognostic performance of seven proposed computed tomography (CT)-severity score (CTSS) systems in two different age groups.Design: Retrospective study.Setting: COVID-19 pandemic.Participants: Admitted COVID-19, PCR-positive patients were included, excluding patients with heart failure and significant pre-existing pulmonary disease.Methods: Patients were divided into two age groups: ≥65 years and ≤64 years. Clinical data indicating disease severity at presentation and at peak disease severity were recorded. Initial CT images were scored by two radiologists according to seven CTSSs (CTSS1-CTSS7). Receiver operating characteristic (ROC) analysis for the performance of each CTSS in diagnosing severe/critical disease on admission (triage performance) and at peak disease severity (prognostic performance) was done for the whole cohort and each age group separately.Results: Included were 96 patients. Intraclass correlation coefficient (ICC) between the two radiologists scoring the CT scan images were good for all the CTSSs (ICC=0.764-0.837). In the whole cohort, all CTSSs showed an unsatisfactory area under the curve (AUC) in the ROC curve for triage, excluding CTSS2 (AUC=0.700), and all CTSSs showed acceptable AUCs for prognostic usage (0.759-0.781). In the older group (≥65 years; n=55), all CTSSs excluding CTSS6 showed excellent AUCs for triage (0.804-0.830), and CTSS6 was acceptable (AUC=0.796); all CTSSs showed excellent or outstanding AUCs for prognostication (0.859-0.919). In the younger group (≤64 years; n=41), all CTSSs showed unsatisfactory AUCs for triage (AUC=0.487-0.565) and prognostic usage (AUC=0.668-0.694), excluding CTSS6, showing marginally acceptable AUC for prognostic performance (0.700).Conclusion: Those CTSSs requiring more numerous segmentations, namely CTSS2, CTSS7, and CTSS5 showed the best ICCs; therefore, they are the best when comparison between two separate scores is needed. Irrespective of patients' age, CTSSs show minimal value in triage and acceptable prognostic value in COVID-19 patients. CTSS performance is highly variable in different age groups. It is excellent in those aged ≥65 years, but has little if any value in younger patients. Multicenter studies with larger sample size to evaluate results of this study should be conducted.

A comparative study between Wagner’s classification and new wound based diabetic foot ulcer severity score

Background: Diabetes is considered to be one of the most common health problems all over the world in 21st century. In fact, it has been coined the ‘Black death of the 21st century due to its stark similarities with the 14th century plague in terms of rapid increase in its prevalence, morbidity and mortality. According to WHO, the number of diabetic patients in 2000 reached to 171 million and was predicted to increase to 380 million by 2020. The Indian diabetic population is expected to increase to 57 million by the year 2025. Diabetic foot ulcers are one of the most distressing complications of diabetes affecting around 15% of people with diabetes. The annual incidence of diabetic foot ulcers is around 3% and the reported incidence in U.S and U.K studies ranges as high as 10%. It has been reported that 85% of the lower limb amputations in diabetic patients are preceded by foot ulceration. These systems are variously based on the site of ulcer, depth, and presence or absence of neuropathy, infection and peripheral arterial disease and have been used to compare the outcomes. Diabetic ulcer severity score (DUSS) is one of the latest wound-based systems of classification. However, there is paucity of enough data to validate whether DUSS system is better as compared to other established and commonly used scoring system like Wagner’s classification. Hence, it was decided to validate DUSS scoring system with Wagner’s classification by comparing both keeping in view outcome of the disease. Methods: Patients admitted under various surgical units from January 2022-January 2023, at Mamata medical college and hospital, Khammam. Total of 40 diabetic patients with diabetic foot ulcers irrespective of their duration, attending surgical outpatient clinic or admitted into the hospital (Mamata general hospital) were recruited into the study based on the inclusion and exclusion criteria mentioned below. Results: DUSS score and Wagner’s score were found to be almost equal in evaluating the scores for treatment as p value was found to be statistically significant (p=0.001) and by KAPPA stats there was an absolute agreement (score 1) between DUSS and Wagner’s scoring system. Conclusions: The new severity scoring system (DUSS) is equal to gold standard Wagner’s scoring system for predictive analysis which also provides an early idea regarding hospital admission, local surgery and health care costs. Since this scoring system 72 can be easily applied in daily clinical practice, it may be suitable in estimating putative healthcare costs.

Validation of the Asthma Severity Scoring System (ASSESS) in the ALLIANCE Cohort

The Asthma Severity Scoring System (ASSESS) quantifies asthma severity in adolescents and adults. Scale performance in children younger than 12 years is unknown. To validate the ASSESS score in the All Age AsthmaCohort and explore its use in children younger than 12 years. Scale properties, responsiveness, and known-group validity were assessed in 247 children (median age, 11 years; interquartile range, 8-13 years) and 206 adults (median age, 52 years; interquartile range, 43-63 years). Overall, measures of internal test consistency and test-retest reliability were similar to the original data of the Severe Asthma Research Program. Cronbach α was 0.59 in children aged 12 to 18 years and 0.73 in adults, reflecting the inclusion of multiple and not-always congruent dimensions to the ASSESS score, especially in children. Analysis of known-group validity confirmed the discriminatory power, because the ASSESS score was significantly worse in patients with poor asthma control, exacerbations, and increased salbutamol use. In children aged 6 to 11 years, test-retest reliability was inferior compared with that in adults and adolescents (Cronbach α, 0.27) mostly because of a less lung function impairment in children with asthma of this age group. Known-group validity, however, confirmed good discriminative power regarding severity-associated variables similar to adolescents and adults. Test-retest reliability and validity of the ASSESS score was confirmed in the All Age Asthma Cohort. In children aged 6 to 11 years, internal consistency was inferior compared with that in older patients with asthma; however, test validity was good and thus encourages age-spanning usage of the ASSESS score in all patients 6 years or older.

Clinical care pathway appropriateness of the intoxicated paediatric patient: a retrospective evaluation with Poisoning Severity Score

to assess the clinical care impact resulting from the lack of a regional reference Centre for Paediatric Poisoning in Liguria Region (Northern Italy) and to describe the demographic and clinical characteristics of paediatric patients who accessed the Emergency Department of the 'Gaslini' Paediatric Hospital (Genoa, Liguria Region) for intoxication. retrospective cohort study. patients' cases of both sexes, <18 years old, who accessed the Emergency Department of the 'Gaslini' Paediatric Hospital between January 2017 and December 2019 for intoxication. the Poisoning Severity Score (PSS), a simple and reliable scoring system to describe poisonings and define their severity, was used. The primary objective was pursued by investigating the percentage of cases of intoxication which followed, in the study period, a clinical care pathway inconsistent with the degree of severity ascertained through the retrospective application of the PSS. Clinical-demographic data, triage tag color-coding, and causes of intoxication of cases were also collected. Descriptive statistics were used to summarize results. a total of 172 cases were identified over the study period; 28 did not meet the inclusion criteria. The final analysis involved 144 cases of intoxication, 70 were from females and 74 from males, with a median age of 3 years-old; 60% of study cases followed a clinical care pathway consistent with the intoxication severity ascertained trough the PSS, in 40% of study cases the clinical care pathway was inconsistent with PSS. The triage tag colour-code assigned was green in 16% of accesses, yellow in 82%, and red in only 2%. Out of the total of accesses, 40% of cases were attributed to drug intoxication in which the agents most involved were analgesics and sedative-hypnotic drugs, 30% to carbon monoxide and fumes poisoning, 23% to food/other substance intoxication, and 7% to alcohol intoxication. implementing a referral Centre for Paediatric Poisoning could potentially affect 40% of access to the Emergency Department. Further analysis should be carried out to clarify whether an integrated Telemedicine Service could guide the correct management of intoxicated paediatric patients by referring them, through the Poisoning Severity Score system, for home monitoring or immediate hospitalization, if necessary.

Implementation and clinical utility of stability and severity scoring systems in the Fabry disease cohort in Northern Ireland

Implementation and clinical utility of stability and severity scoring systems in the Fabry disease cohort in Northern Ireland

Association between the severity of histopathological lesions and Mycobacterium avium subspecies paratuberculosis (MAP) molecular diversity in cattle in southern Chile.

The objective was to evaluate the association between the severity of histopathological lesions caused by Mycobacterium avium subspecies paratuberculosis (MAP) infection and the molecular diversity of this pathogen. Blood, ileum, and mesenteric lymph node samples were collected at slaughter, from 1,352 adult cattle [source population 1 (SP1)]. In addition, 42 dairy herds (n = 4,963 cows) were followed for 2 years, and samples from compatible paratuberculosis clinical cases [source population 2 (SP2)] were collected. MAP infection was confirmed using an ELISA test, liquid media culture, and PCR. Isolates were genotyped using five MIRU-VNTR markers. Tissues from confirmed samples were subjected to a histopathological examination. A histopathological severity score (HSS) system was developed and used to grade (0 to 5) the magnitude of lesions caused by MAP. In general, the HSS system assesses the number of foci and degree of macrophage infiltration, together with the presence of multinucleated giant cells (MGCs) and acid-fast bacilli (AFB), in addition to the fusion of the intestinal villi and hyperplasia of the crypts. Despite the large sampling effort, only 79 MAP isolates were successfully genotyped, where 19 different haplotypes were described. A mixed-effect Poisson regression model was used to assess the relationship between haplotypes and HSS values. The model was controlled by animal age, and the farm was used as a random effect. Haplotypes were grouped based on their relative frequency: the most frequent haplotype (group i, 49.4%), the second most frequent haplotype (group ii, 12.7%), and all other haplotypes (group iii, 37.9%). Model outputs indicated that group i had significantly higher HSS values than group iii. In addition, group i was also associated with higher optical density (OD) values of the ELISA test. These results support the existence of differences in pathogenicity between MAP haplotypes. However, results were based on a relatively small sample size; thus, these should be taken with caution. Despite this, study findings suggest that haplotypes would be associated with differences in disease progression, where the dominant haplotype tends to generate more severe lesions, which could be linked to a greater shed of MAP cells than non-dominant haplotypes, increasing their chances of transmission.

Ocular findings and their correlation with disease severity in Fabry disease in South-East Anatolia.

To evaluate the ocular findings and the relationship between these findings and the disease severity of patients with Fabry disease (FD) in South-East Anatolia. We enrolled the 24 eyes of 24 patients with FD and the disease severity scores were obtained with FD severity scoring system (DS3). The relationship between the presence of any ocular findings and DS3 scores was evaluated. The mean age of the patients was 35.2 ± 8.6years. The mean DS3 score and α-galactosidase A enzyme activity of the patients was 7.04 ± 3.71 and 1.93 ± 0.84μmol/l/h, respectively. Of the 24 patients, 20 (83.3%) had cornea verticillate (CV), 18 (75%) had tortuous conjunctival vessels, 15 (62.5%) had tortuous retinal vessels and 3 (12.5%) had lens opacities. The ocular vascular abnormalities were associated with disease severity (p < 0.05); however, the presence of CV did not affect the DS3 scores (p > 0.05). According to our study, the patients with ocular vascular abnormalities associated with FD had more severe disease than those who did not have an abnormality. CV was the most common ocular finding in FD, but it has no association with disease severity.

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

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. 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. 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, β-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. 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.

A retrospective and comparative study between quick sequential organ failure assessment, CURB-65, and early warning scorings in COVID-19 patients to predict the disease severity and outcome

Background: Predicting the severity of COVID-19 infection in advance is the key to success of its treatment outcome. Various scoring systems are used to detect the severity of this disease but this study targets three simple scoring systems based on the vital parameters and basic routine laboratory tests. Aims and Objectives: The aim of the study was to assess the predictability of three scoring systems (Quick sequential organ failure assessment [q SOFA], CURB-65, and Early Warning scoring system) for disease severity at presentation in a rural-based tertiary care center. Materials and Methods: An observational, descriptive, retrospective, and cross-sectional study was conducted at Diamond Harbour Government Medical College Covid Hospital from January 2021 to January 2022 to assess the predictability of q SOFA, CURB-65, and Early Warning scoring system for disease severity at presentation. Results: The total number of participants was 561 among total admitted 1367 patients. A short descriptive analysis obtained from the variables to analyze the scorings howed among total sample collected, 57% were male and 43% were female. In this study, 87% of patients were survived and the rest 13% succumbed (death). There is no statistically significant difference in mortality between both genders. Age, pulse rate, and respiratory rate have a significant correlation with the outcome and altered sensorium is also highly associated with mortality. The accuracy was also found to be little higher for National Early Warning score (NEWS) score than CURB-65 scoring and q SOFA scoring (0.919, 0.914 and 0.907). Although all the scoring systems have high sensitivity (&gt;90%) (CURB 65: Most sensitive [0.99]), the specificities of all three scoring systems are below 50%. Among these three-scoring systems, NEWS showed the highest specificity (0.492) than q SOFA (0.423) and CURB 65 (0.394). Conclusion: We suggest NEWS score and CURB-65 as a better predictor for in-hospital mortality in COVID-19 patients as it is significantly sensitive and reasonably specific. It can be recommended in less equipped hospitals where only basic laboratory facilities are available. qSOFA can be utilized where no laboratory facility is available like in safe home and isolation centers.

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 level (Alb) as well as white blood cell count (WBC) 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.
