Abstract BackgroundEvidence indicates that single nucleoid polymorphisms (SNPs) of key molecules in innate immunity are related to clinical outcome of community-acquired pneumonia (CAP). Pentraxin 3 (PTX3) is a member of the acute-phase reactants superfamily and plays an important role against various diseases. The purpose of the current study was to assess the association between PTX 3 SNP and the risk of CAP.MethodsThis is a retrospective case-control study. Patients who were diagnosed with CAP between January 2018 to December 2019 in the Department of Pulmonary and Critical Care Medicine at Sun Yat-sen Memorial Hospital were included as CAP group. Then CAP cases were matched 1:1 by gender with non-infectious hospitalized patients during the same time. We detected the genotypes, allele frequencies and haplotype distributions of three SNPs within PTX3 gene (rs2305619, rs3816527, and rs1840680) by polymerase chain reaction sequencing in CAP group and control group, and compared their associations with the risk of CAP.ResultsThree SNPs in both groups were consist with Hardy-Weinberg equilibrium. A strong linkage disequilibrium was detected between any pair of rs2305619, rs3816527 and rs1840680 (|D’|≥0.85). There were no differences of rs2305619 and rs3816527 in genotypic distribution and haplotype frequency between CAP group and control group. However, we identified that SNP rs1840680 AA homozygote was associated with a lower risk of CAP in adults (OR, 0.32; 95% CI, 0.11-0.91; p = 0.03).ConclusionsOur findings suggested that PTX3 single nucleoid polymorphism was associated with the risk of CAP in adults.

Rivaroxaban after total knee arthroplasty (TKA) is used to prevent postoperative venous thromboembolism (VTE); however, despite thromboprophylaxis, some patients still develop postoperative VTE. To determine whether tourniquet time, time to initiate rivaroxaban (TTIRIV), or Body Mass Index (BMI) was associated with postoperative VTE. A retrospective case-control study was conducted. Those patients that developed VTE despite prophylaxis (cases) were compared to controls (no VTE). A univariate analysis was conducted (p < 0.05 statistically significant). Seven VTE cases were identified from 234 TKA-patients. Patients with and without VTE had BMI of 40.1 ± 9.1 and 32.8 ± 7.5, respectively (p = 0.064). TTIRIV in VTE and control group was 28.2 ± 4.7 hours and 26.4 ± 4.2 hours, respectively (p = 0.39). Mean tourniquet time in VTE and control group was 65.0 ± 8.7 minutes and 49 ± 8.8 minutes, respectively (p = 0.0007). Statistically significant differences in tourniquet times were noted between VTE and non-VTE group but not for TTIRIV and BMI. Prolonged tourniquet use could pose a potential risk factor for postoperative VTE. Thromboprophylaxis management may need to be adjusted, based on patient-specific factors that could include increasing doses of oral anticoagulants and/or mechanical prophylaxis. However, further large-scale studies are required to establish pathophysiology.

The aim of this retrospective case-control study is to determine a possible correlation between breathing mode and craniofacial morphology. The study was carried out in the Department of Pedodontics,Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania. The sample comprised 80 patients, age between 6 and 13 years, which were divided in two groups based on respiratory pattern: control group composed of 38 nasal breathing children and case group composed of 42 oral breathing children. Three quantitative craniofacial parameters were measured from the frontal and lateral photos: facial index, lower facial height ratio and upper lip ratio. The statistical analysis showed a significant higher facial index (p=0.006*) and an increase lower facial height (p=0.033*) for the oral breathers group. No differences in facial morphology were found between genders and age groups, when comparing the data between the same type of respiratory pattern children. Spearman�s rho Correlation show a significant positive correlation (p=0.002*) between facial index and lower facial height and a significant negative correlation between facial index and upper lip (p=0,005*). Long faces children are more likely to develop oral breathing in certain conditions, which subsequently have a negative effect on increasing the lower facial height by altering the postural behavior of mandible and tongue.

Abstract Background Parkinson’s disease is one of the neurodegenerative disorders that is caused by genetic and environmental factors or interaction between them. Solute carrier family 41 member 1 within the PARK16 locus has been reported to be associated with Parkinson’s disease. Cognitive impairment is one of the non-motor symptoms that is considered a challenge in Parkinson’s disease patients. This study aimed to investigate the association of rs11240569 polymorphism; a synonymous coding variant in SLC41A1 in Parkinson’s disease patients in addition to the assessment of cognitive impairment in those patients. Results In a case -control study, rs11240569 single nucleotide polymorphisms in SLC41A1, genes were genotyped in 48 Parkinson’s disease patients and 48 controls. Motor and non-motor performance in Parkinson's disease patients were assessed by using the Movement Disorder Society-Sponsored Revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS). The genotype and allele frequencies were compared between the two groups and revealed no significant differences between case and control groups for rs11240569 in SLC41A1 gene with P value .523 and .54, respectively. Cognition was evaluated and showed the mean ± standard deviation (SD) of WAIS score of PD patients 80.4 ± 9.13 and the range was from 61 to 105, in addition to MMSE that showed mean ± SD 21.96 ± 3.8. Conclusion Genetic testing of the present study showed that rs11240569 polymorphism of SLC41A1 gene has no significant differences in distributions of alleles and genotypes between cases and control group, in addition to cognitive impairment that is present in a large proportion of PD patients and in addition to the strong correlation between cognitive impairment and motor and non-motor symptoms progression.

Abstract BACKGROUND Intraoperative prediction of postoperative cerebral hyperperfusion syndrome (CHS) after cerebrovascular bypass surgery is challenging. OBJECTIVE To conduct a retrospective case-control study with indocyanine green (ICG) intensity analysis of the superficial temporal artery-middle cerebral artery (STA-MCA) bypass and investigate whether its washout pattern might be a marker for intraoperative prediction of CHS. METHODS Between 2012 and 2018, 6 of 112 patients (5.4%) that underwent STA-MCA bypass exhibited CHS. We selected 5 patients with CHS (3 with atherosclerotic cerebrovascular disease [ASCVD] and 2 with moyamoya) and 15 patients without CHS (60% ASCVD and 40% moyamoya) as a matched control group. During prebypass and postbypass, washout times (WTs) for the first 10%, 25%, 50%, and 75% of maximum ICG intensity measured in the whole-camera field were compared between groups. The changes in WT (ΔWT) from prebypass to postbypass for each ICG intensity level were compared between groups. The cutoff ΔWTs, sensitivities, and specificities were also calculated. RESULTS Postbypass WTs were significantly longer in the CHS group than the control group at all ICG intensities (P < .05). ΔWT was significantly greater in the CHS group than the control group for the first 10%, 25%, and 50% ICG intensities (P < .001). A cutoff ΔWT of ≥2.66 s for the first 50% ICG intensity showed a sensitivity of 100% and specificity of 100%. CONCLUSION We found that a ΔWT ≥2.66 s for the first 50% ICG intensity could be an intraoperative predictive factor for CHS.

BACKGROUND: The COVID-19 pandemic has created a wide range of sociocultural pressures on nurses. Resilience is defined as one’s ability to adapt to an unpredictable situation and it can be a factor in accepting an undesirable psychosocial situation. OBJECTIVE: The aim of the present study was to examine resilience in nurses in the face of job stress during the COVID-19 pandemic. METHODS: The study was carried out as a case-control study with participation of 400 nurses as the target group (nurses exposed to COVID-19 patients) and the control group (nurses not exposed to COVID-19 patients). To examine resilience and job stress, Conor and Davidson’s questionnaire and OSIPOW questionnaire were used respectively. RESULTS: The mean scores of job stress and resilience were significantly different between the target and control groups (p <  0.05). So that resilience in the target group was less than that in the control group. In addition, job stress in the target group was higher than that of the control group (p <  0.05). There was a significant and negative correlation between resilience and job stress and the correlation was stronger in the target group (p <  0.05). CONCLUSIONS: Given the high job stress score in the participants and its negative correlation with resilience, there is need to provide the health personnel with efficient preventive and treatment approaches, improve and educate the principles of resilience, improve mental health services system, and introduce programs to control some of demographical factors in job stress such as physical activity, and employment status of nurses.

Introduction Optimal management of lower extremity fractures includes early antibiotics administration, thorough irrigation and debridement, consideration of soft tissue injury, and definitive skeletal management. The purpose of this study was to evaluate the efficacy of topical vancomycin powder in the treatment of open lower extremity fractures. Methods This was a retrospective case control study in which open lower extremity fractures at our institution were reviewed for development of infection (including species and sensitivity if present) and the development of unanticipated wound complications requiring intervention. Patients from 2010-2015 were treated with standard of care consistent with evidence-based literature (IV antibiotics with external fixator, intramedullary nail, etc.). Patients from 2016–18 were additionally treated with vancomycin powder applied directly to the wound before closure. All patients were monitored per the treating surgeon’s standard follow-up protocol and had follow-up of at least two months. Results This retrospective case control study comprised 434 patients. The historical control group (n = 388 patients) and treatment group (n = 46 patients) were similar for age, sex, BMI (body mass index), diabetes, smoking status, and Injury Severity Score (ISS). There were 36 infections (9.28%) in the control group compared to four infections (8.70%) in the vancomycin powder group (p = 0.901). No significant difference was seen after adjusting for age, sex, BMI, diabetes, smoking status, and ISS. The vancomycin powder group experienced significantly more wound complications (15.2%) compared to the control group (6.4%; p = 0.039), which remained significant when adjusting for multiple covariates. Conclusions Topical vancomycin powder did not reduce the infection rate when applied in the surgical site of open lower extremity fractures. Instead, the addition of topical vancomycin powder resulted in significantly more wound complications in patients with open lower extremity fractures.

AbstractObjectivesPharyngocutaneous fistulae are dreaded complications following total laryngectomy. This paper presents our experience using 3–5 ml gastrografin to detect pharyngeal leaks following total laryngectomy, and compares post-operative videofluoroscopy with clinical follow-up findings in the detection of pharyngocutaneous fistulae.MethodsA retrospective case–control study was conducted of total laryngectomy patients. The control group (n = 85) was assessed clinically for development of pharyngocutaneous fistulae, while the study group (n = 52) underwent small-volume (3–5 ml) post-operative gastrografin videofluoroscopy.ResultsIn the control group, 24 of 85 patients (28 per cent) developed pharyngocutaneous fistulae, with 6 requiring surgical correction. In the study group, 24 of 52 patients (46 per cent) had videofluoroscopy-detected pharyngeal leaks; 4 patients (8 per cent) developed pharyngocutaneous fistulae, but all cases resolved following non-surgical management. Patients who underwent videofluoroscopy had a significantly lower risk of developing pharyngocutaneous fistulae; sensitivity and specificity in the detection of pharyngocutaneous fistulae were 58 per cent and 100 per cent respectively.ConclusionSmall-volume gastrografin videofluoroscopy reliably identified small pharyngeal leaks. Routine use in total laryngectomy combined with withholding feeds in cases of early leaks may prevent the development of pharyngocutaneous fistulae.

Background Tight control of severe rheumatoid arthritis (RA) in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA) in patients undergoing switching of biologics. We performed this retrospective case–control study to investigate the efficacy of achieving an immediate treatment response using the K-method. Methods This study involved 20 patients with RA (control group, 10 patients; K-method group, 10 patients). Patients in the control group were switched to golimumab from other biologics without intra-articular injection of TA. The K-method involved injection of 1 mL of TA (40 mg/mL) and 2 mL of 1% lidocaine hydrochloride into swollen or painful joints on the same day as golimumab treatment. A quick response one day after treatment was compared between the two groups according to the disease activity score 28 based on C-reactive protein (DAS28 CRP), clinical disease activity index (CDAI), simplified disease activity index (SDAI), European League Against Rheumatism (EULAR) response, and remission rate. These parameters were investigated for 24 weeks. Results The K-method group showed significant improvements in DAS28 CRP, CDAI, and SDAI at one day, 12 weeks, and 24 weeks compared with the control group. The number of swollen and tender joints and the patient and doctor global visual analog scale scores were also significantly different between the two groups. The remission rates based on DAS28 CRP were 30% at one day, 50% at 12 weeks, and 60% at 24 weeks in the K-method group. The EULAR good/moderate response rates were 80% at one day, 90% at 12 weeks, and 90% at 24 weeks in the K-method group; however, these rates were only 10%, 40%, and 40%, respectively, in the control group. No adverse events occurred in either group. Conclusion Simultaneous treatment with biologics and intra-articular injection of TA is useful for cases involving switching of biologics for RA. This strategy is safe and practical for RA treatment.
