ABSTRACT

BACKGROUND: The intent of this research was to generate and investigate the D-dimer to lymphocyte ratio (DLR) capacity to forecast the risk and prognosis of colorectal cancer liver metastases (CRCLM).

METHODS: From January 2010 to December 2019, 177 clinicopathologically confirmed colorectal cancer (CRC) patients (89 in the control group and 88 in the experimental group) were identified at the Affiliated Cancer Hospital of Guangxi Medical University. Multivariate Cox regression analysis was used to screen independent predictive diagnostic and prognostic factors of liver metastasis in CRC, and receiver operating characteristic (ROC) curves and Kaplan‒Meier (K‒M) curves were established to analyze the diagnostic and predictive prognostic efficacy of the DLR in the development of CRCLM.

RESULTS: Patients with CRCLM had higher DLR levels and D-dimer levels in their blood, with statistically significant differences (p < 0.001). DLR might be employed as a predictor for the development of CRCLM, according to ROC curve research (sensitivity 0.670, specificity 0.775, area under the curve 0.765). D-dimer, lymphocyte count CEA, CA125, and CA199 were not linked to prognosis in patients with CRCLM in Cox regression analysis of dichotomous variables. In contrast, DLR level was a possible risk factor for the prognosis of patients with CRCLM (HR = 2.108, p = 0.047), and age, T stage, and DLR level (DLR < 0.4) were connected with the prognosis of patients with CRCLM (p < 0.05).

CONCLUSION: DLR serves as a risk indicator for the development of CRCLM.

ABSTRACT

INTRODUCTION: The key objective of this research was to describe the prescription rate of various antibiotics for dental problems in India and to study the relevance of the prescriptions by analysing antibiotic types associated with different dental diagnoses, using a large-scale nationally representative dataset.

METHODS: We used a 12-month period (May 2015 to April 2016) medical audit dataset from IQVIA (formerly IMS Health). We coded the dental diagnosis provided in the medical audit data to the International Statistical Classification of Diseases and Related Health Problems (ICD-11) and the prescribed antibiotics for the diagnosis to the Anatomic Therapeutic Chemical (ATC) -2020 classification of the World Health Organization. The primary outcome measure was the medicine prescription rate per 1,000 persons per year (PRPY₁₀₀₀).

RESULTS: Our main findings were-403 prescriptions per 1,000 persons per year in the year 2015 -2016 for all dental ailments. Across all ATC level 1 classification, ‘Diseases of hard tissues’ made up the majority of the prescriptions. ‘Beta-lactam’, ‘Penicillin,’ and ‘Cephalosporins’ were the most commonly prescribed antibiotics for dental diagnoses followed by ‘Macrolides’ and ‘Quinolones’. ‘Dental caries’, ‘Discoloration of tooth’, and ‘Toothache’ were the most common reasons for ‘Beta-Lactams’ and ‘Penicillin’ prescriptions.

CONCLUSION: To conclude our study reports first ever country (India) level estimates of antibiotic prescription by antibiotic classes, age groups, and ICD-11 classification for dental ailments.

ABSTRACT

BACKGROUND: Clinical guidelines should be based on a thorough evaluation of the evidence and generally include a rating of the quality of evidence and assign a strength to recommendations. Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidance warns against making strong recommendations when the certainty of the evidence is low or very low, but has identified five paradigmatic situations (e.g. life-threatening situations) where this may be justified.

AIMS AND OBJECTIVES: We aimed to characterize the strength of recommendations and certainty of the evidence in Irish National Clinical Guidelines using the GRADE approach.

METHODS: All National Clinical Guidelines from the National Clinical Effectiveness Committee (NCEC) website using the GRADE approach (fully or partially) were included. All recommendations and their corresponding certainty of the evidence, strength of recommendations and justifications were extracted. Authors classified instances of strong recommendations with low certainty evidence (referred to as discordant recommendations) into one of the five paradigmatic situations. Descriptive statistics were calculated.

RESULTS: From the 29 NCEC Clinical Guidelines available at the time of analysis, we identified 8 guidelines using GRADE with a total of 240 recommendations; 38 recommendations did not use the GRADE approach and were excluded. Half of the included guidelines focused on emergency situations. In the final dataset of 202 recommendations, 151 (74.7%) were classified as strong and 51 (25.3%) as conditional. Of the 151 strong recommendations, 55 (36.4%) were supported by high or moderate certainty evidence and 96 (63.6%) by low or very low certainty evidence and were considered discordant. Of these 96 discordant recommendations, 55 (73.7%) were consistent with one of the five paradigmatic situations. However, none were specifically described as such within the guidelines.

CONCLUSIONS: The proportion of discordant recommendations identified in this analysis was higher than some previous international studies (range of all strong recommendations being discordant 30-50%), but similar to other guidelines focused on emergency situations. The majority of discordant recommendations could be mapped to one of the five situations, but no National Clinical Guideline explicitly referenced this. Guideline developers require further guidance to enable greater transparency in the reporting of the reasons for discordant recommendations.

ABSTRACT

STUDY DESIGN: Qualitative studies.

OBJECTIVE: To develop clear and specific administration and scoring procedures for the Spinal Cord Independence Measure Version 3.0 as a performance-based and interview assessment.

SETTING: Research lab.

METHODS: Modified Delphi Technique survey methods were used in this study. Previously developed SCIM-III administration and scoring procedures for performance-based and interview versions were presented to clinicians experienced in SCI and SCIM-III using the Qualtrix (Qualtrics, Provo, UT) online survey platform. Summary and descriptive statistics were used to assess the percent agreement survey responses.

RESULTS: Three survey rounds were necessary to achieve 80% agreement or above for the performance-based version. Two survey rounds were necessary to achieve 80% agreement or above on the interview version.

CONCLUSIONS: This study describes the development of standardized administration and scoring procedures for the self-care and mobility sub-scales of the SCIM-III as a performance-based and interview version.

ABSTRACT

Gene-environment (G×E) interaction could partially explain missing heritability in traits; however, the magnitudes of G×E interaction effects remain unclear. Here, we estimate the heritability of G×E interaction for body mass index (BMI) by subjecting genome-wide interaction study data of 331,282 participants in the UK Biobank to linkage disequilibrium score regression (LDSC) and linkage disequilibrium adjusted kinships-software for estimating SNP heritability from summary statistics (LDAK-SumHer) analyses. Among 14 obesity-related lifestyle factors, MET score, pack years of smoking, and alcohol intake frequency significantly interact with genetic factors in both analyses, accounting for the partial variance of BMI. The G×E interaction heritability (%) and standard error of these factors by LDSC and LDAK-SumHer are as follows: MET score, 0.45% (0.12) and 0.65% (0.24); pack years of smoking, 0.52% (0.13) and 0.93% (0.26); and alcohol intake frequency, 0.32% (0.10) and 0.80% (0.17), respectively. Moreover, these three factors are partially validated for their interactions with genetic factors in other obesity-related traits, including waist circumference, hip circumference, waist-to-hip ratio adjusted with BMI, and body fat percentage. Our results suggest that G×E interaction may partly explain the missing heritability in BMI, and two G×E interaction loci identified could help in understanding the genetic architecture of obesity.

ABSTRACT

A cross-sectional study was performed at Hebei Medical University Fourth Affiliated Hospital from April to July 2020 to explore the difference and consistency between nurses and physicians in terms of symptomatic adverse event (AE) assessment. The Common Terminology Criteria for Adverse Events (CTCAE) was utilized by nurses and physicians to assess patients’ symptomatic AEs. Patients self-reported their AEs utilizing the Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). Four nurses and three physicians were enrolled to assess patients’ symptomatic AEs. Given the same AEs, nurses tended to detect more AEs than physicians, and the differences were statistically significant (P < 0.001). The toxicity grade reported by nurses and physicians showed no difference for all AEs, except for fatigue (χ² = 5.083, P = 0.024). The agreement between nurses and patients was highest compared to the agreement between nurses versus physicians and physicians versus patients. The differences in symptomatic AE assessment can lead to different symptom management. Thus, it is important to establish a collaborative approach between nurses and physicians to ensure continuity in care delivery.

ABSTRACT

BACKGROUND: Costello syndrome (CS) is a cancer-predisposition disorder caused by germline pathogenic variants in HRAS. We conducted a systematic review using case reports and case series to characterise cancer risk in CS.

METHODS: We conducted a systematic review to identify CS cases to create a retrospective cohort. We tested genotype-phenotype correlations and calculated cumulative incidence and hazard rates (HR) for cancer and cancer-free death, standardised incidence rates (SIR) and survival after cancer.

RESULTS: This study includes 234 publications reporting 621 patients from 35 countries. Over nine percent had cancer, including rhabdomyosarcoma, bladder, and neuroblastoma. The rate of cancer and death associated with p.Gly12Ser were lower when compared to all other variants (P < 0.05). Higher mortality for p.Gly12Cys, p.Gly12Asp, p.Gly12Val and p.Gly60Val and higher malignancy rate for p.Gly12Ala were confirmed (P < 0.05). Cumulative incidence by age 20 was 13% (cancer) and 11% (cancer-free death). HR (death) was 3-4% until age 3. Statistically significant SIRs were found for rhabdomyosarcoma (SIR = 1240), bladder (SIR = 1971), and neuroblastoma (SIR = 60). Survival after cancer appeared reduced.

CONCLUSIONS: This is the largest investigation of cancer in CS to date. The high incidence and SIR values found to highlight the need for rigorous surveillance and evidence-based guidelines for this high-risk population.

ABSTRACT

INTRODUCTION: Pertussis, a highly infectious respiratory disease caused by Bordetella pertussis, affects people of all ages. Older adults are particularly susceptible to its severe outcomes and complications.

METHODS: In this retrospective cohort study, the incidence rate of pertussis among individuals aged ≥ 50 years was assessed during 2009-2018 using Clinical Practice Research Datalink and Hospital Episode Statistics databases, United Kingdom. Health care resource utilisation (HCRU) and direct medical costs (DMCs) were compared between patients with a pertussis diagnosis and propensity score-matched controls (matched on demographic and clinical variables).

RESULTS: Among 5,222,860 individuals, 1638 had a pertussis diagnosis (incidence rate: 5.8 per 100,000 person-years; 95% confidence interval 5.5-6.0). Baseline (- 18 to – 6 months) HCRU and DMC were similar among 1480 pertussis patients and 1480 matched controls. However, there were increases in HCRU in the pertussis vs. matched cohort around the pertussis diagnosis (from months – 6 to – 1 to 5-11). The most notable increases (pertussis vs. controls) were in the rates of general practitioner (GP)/nurse visits (4.7-fold), clinical assessments (4.1-fold), and accident and emergency visits (3.0-fold) during the month before diagnosis and GP/nurse visits during the 2 months after diagnosis (2.5-fold) (all p < 0.001). DMCs were significantly higher in the pertussis cohort (p < 0.001). Total excess DMC in the pertussis cohort during months – 1 to + 11 was £318 per patient.

CONCLUSION: A pertussis diagnosis among adults aged ≥ 50 years resulted in significant increases in HCRU and DMC across several months around diagnosis. These results highlight the need for increased awareness of pertussis infection among adults aged ≥ 50 years and suggest that pertussis booster doses among this population should be considered.

ABSTRACT

Visual-related quality of life in retinal diseases has not been explored in the Mexican population, so the study aims to identify it in patients undergoing surgery due to advanced diabetic retinopathy, rhegmatogenous retinal detachment, and other causes of vitrectomy; the Visual Function Quality-25 questionnaire was applied to 76 patients, pre-and postoperative. It was divided into 10 domains and interpreted according to the National Eye Institute scores, where the highest value was the best visual function. Student’s t-test for related samples and Wilcoxon’s t-test were used to compare each domain between measurements, and Pearson’s R test to correlate the total score of age and quality of life; a p value < 0.05 was considered significant. Diabetic retinopathy patients showed an improvement 1 and 3 months after surgery in all domains; in rhegmatogenous retinal detachment, there was an improvement observed up to 3 months, while a decrease in ocular pain was observed in other causes of vitrectomy. Differences found in all the quality-of-life scores were not statistical, but clinically significant. The study shows that visual-related quality of life domains improves after vitrectomy; the inclusion of this analysis might be considered relevant within the parameters of surgical success of the most prevalent vitreoretinal diseases.

ABSTRACT

Previous studies using immunoassays for steroid measurements have focused on the association between steroid hormone levels and bone mineral density (BMD) in postmenopausal women, obtaining contradictory results. This study aimed to assess this association using a highly sensitive bioanalytical method. A total of 68 postmenopausal women, aged 65-89 years, were enrolled in a cross-sectional study. Measurements of the BMD of the hip and lumbar spine were performed using dual energy X-ray absorptiometry, and serum hormone levels were quantified by gas chromatography and tandem mass spectrometry. Associations between estradiol (E2), testosterone, dehydroepiandrosterone (DHEA), androstenedione and T score levels of the hip and lumbar spine were evaluated, after adjustment for confounding variables. The analysis revealed a statistically significant association between testosterone and the T score of the hip (p = 0.035), but not that of the lumbar spine. No statistically significant associations were found between E2, DHEA, androstenedione and the T scores of the hip and the lumbar spine. Using a highly sensitive hormone assay method, our study identified a significant association between testosterone and BMD of the hip in women over 65 years of age, suggesting that lower testosterone increases the risk of osteoporosis.
