Total calcium, dairy foods and risk of colorectal cancer: a prospective cohort study of younger US women

alexandrossfakianakis shared this article with you from Inoreader Total calcium, dairy foods and risk of colorectal cancer: a prospective cohort study of younger US women via International Journal of Epidemiology - Advance Access Abstract Background Although colorectal cancer (CRC) incidence is declining among adults aged ≥65 years, CRC incidence in younger adults has been rising. The protective role of calcium in colorectal carcinogenesis has been well established, but evidence is lacking on whether the association varies by age at diagnosis. We investigated the association between total calcium intake and risk of overall CRC and CRC before age 55 years. Methods In the Nurses' Health Study II (1991–2015), 94 205 women aged 25–42 years at baseline were included in the analysis. Diet was assessed every 4 years through validated food frequency questionnaires. Multivariable-adjusted hazard ratios (HRs) and 95% CIs for CRC were estimated using the Cox proportional hazards model. Results We documented 349 incident CRC cases during 2 202 604 person-years of follow-up. Higher total calcium intake was associated with a reduced risk of CRC. Compared with those with <750 mg/day of total calcium intake, the HR of CRC was 0.61 (95% CI, 0.38–0.97) for those who consumed ≥1500 mg/day (P for trend = 0.01). The HR per 300 mg/day increase was 0.85 (95% CI, 0.76–0.95). There was a suggestive inverse association between total calcium intake and CRC before age 55 years (HR per 300 mg/day increase, 0.87; 95% CI, 0.75–1.00), suggesting the importance of calcium intake in the younger population. Conclusions In a cohort of younger women, which reflects the birth cohorts, time periods and age ranges paralleling the recent rise in CRC, higher calcium intake was associated with a decreased risk of CRC.

The Necessity of Nostril Retention Application After Secondary Unilateral Cleft Rhinoplasty

alexandrossfakianakis shared this article with you from Inoreader The Necessity of Nostril Retention Application After Secondary Unilateral Cleft Rhinoplasty via The Laryngoscope The nostril retention after secondary unilateral cleft rhinoplasty could help preserve nasal morphology but worsen the patient's quality of life of the patients. The necessity of nostril retention should consider the forms of nasal deformity and the patient's quality of life. Background This study aims to investigate the necessity of nostril retention after secondary unilateral cleft rhinoplasty. Methods Seventy four patients who underwent secondary unilateral cleft rhinoplasty were categorized into control group, nasal retainer group, and nasal clip group. A nasal retainer or nasal clip was applied 7 days after secondary correction and retained in the nostrils of the patients for 6 to 12 months. Measurements from pre- and post-operative photos and patient-reported outcomes were used in this study. Results After 6 to 12 months, although relapse still occurred in three groups, the nasal retainer group showed a better effect in the ratio of nostril height, whereas the nasal clip group showed a significant improvement in the ratio of nasal base. And both the two groups also showed significant improvement in the ratio of nasal columella. Patients from the control group generally had lower Derriford Appearance Scale (DAS) scores than the nasal retainer group and nasal clip group. Wearing a nasal retainer may negatively influence self-concept, facial self-consciousness of appearance and physical state, and significant differences in mean scores were also found in 9 items. Conclusions The nostril retention after secondary unilateral cleft rhinoplasty could help preserve nasal morphology and reduce postoperative relapse but worsen the patients' quality of life. The necessity of applying the nostril retention should consider the forms of nasal deformity and the potential influence on the quality of life. Level of Evidence 3 Laryngoscope, 2022 View on Web

Postoperative analysis of osseous midface reconstructions: The value of imaging and a novel scoring system for complexity and operative success

alexandrossfakianakis shared this article with you from Inoreader Postoperative analysis of osseous midface reconstructions: The value of imaging and a novel scoring system for complexity and operative success via Head & Neck Abstract Background Few standardized methods exist for evaluating the postoperative outcomes of osteocutaneous free flaps. We propose an anatomic-based scoring system for midface free flap reconstruction. Methods One hundred and twelve patients across four institutions underwent osteocutaneous reconstruction of the midface. Postoperative scans were scored based on the number of independent osseous subunits reconstructed (Subunit Score), the number of different bony appositions with bony contact (Contact Score), and the number of osseous segments in anatomic position (Position Score). These were added together to create a Total Score. Results Osteocutaneous radial forearm flaps had the lowest Subunit Score (p = 0.001). Fibula flaps had the highest Contact Score (p = 0.0008) and Position Score (p = 0.001). Virtual surgical planning was associated with an increased Subunit Score (p = 0.02) and Total Score (p = 0.04). Conclusions We propose a novel scoring system for osseous midface reconstruction based on postoperative imaging scans. This can help guide management decisions and create a common language to compare outcomes. View on Web

Diagnostic efficacy of positron emission computerized tomography scans in suspicious laryngeal findings postorgan preservation treatment

alexandrossfakianakis shared this article with you from Inoreader Diagnostic efficacy of positron emission computerized tomography scans in suspicious laryngeal findings postorgan preservation treatment via Head & Neck Abstract Background Larynx preservation protocols (LPP) for glottic primary squamous cell carcinoma has gained popularity worldwide. Direct laryngoscopy (DL) with biopsy is mandated when recurrence is suspected. The efficacy of 18Fluoro-deoxy-glucose positron emission computerized tomography (PET-CT) as alternative first-line diagnostic investigation in suspected recurrence was evaluated. Methods A retrospective study of patients with suspicious fiber-optic findings at more than 12 weeks after LPP. Sensitivity, specificity, and the negative predictive value (NPV) of DL and PET-CT were compared. Results Seventy-two patients presenting 105 cases of suspicious events were included in this study. Fifty-two events were initially investigated by DL and 53 events by PET-CT. The sensitivity of DL and PET-CT was 56.25% and 100%, respectively. The NPV was 84% for DL and 100% for PET-CT (p = 0.015). Conclusion Negative PET scans after LPP are highly accurate in ruling out recurrent/persistent disease and may spare the patient from negative biopsies. View on Web

Electrochemical Sensors for Oral Biofilm‐Biomaterials Interface Characterization: a review

alexandrossfakianakis shared this article with you from Inoreader Electrochemical Sensors for Oral Biofilm‐Biomaterials Interface Characterization: a review via Molecular Oral Microbiology Abstract Important processes related to the interaction of the oral microbiome with the tooth surface happen directly at the interface. For example, the chemical microenvironment that exists at the interface of microbial biofilms and the native tooth structure is directly involved in caries development. Consequentially, a critical understanding of this interface and its chemical microenvironment would provide novel avenues in caries prevention, including secondary caries that often occurs at the interface of the dental biofilm, tooth structure and dental material. Electrochemical sensors are a unique quantitative tool and have the inherent advantages of miniaturization, stability, and selectivity. That makes the electrochemical sensors ideal tools for studying these critical biofilm microenvironments with high precision. This review highlights the development and applications of several novel electrochemical sensors such as pH, Ca2+, and hydrogen peroxide sensors as scanning ele ctrochemical microscope (SECM) probes in addition to flexible pH wire sensors for real-time bacterial biofilm-dental surface and dental materials interface studies.

Comparative analysis and trends in liver transplant hospitalizations with clostridium difficile infections: A 10‐year national cross‐sectional study

alexandrossfakianakis shared this article with you from Inoreader Comparative analysis and trends in liver transplant hospitalizations with clostridium difficile infections: A 10‐year national cross‐sectional study via Transplant Infectious Disease ABSTRACT Goals and Background Clostridium difficile infection (CDI) is the leading cause of antibiotic-associated diarrhea in the United States. We aimed to determine comparative trends in inpatient outcomes of liver transplant (LT) patients based on CDI during hospitalizations. Methods The national inpatient sample (NIS) database was used to conduct the present retrospective study regarding CDI among the LT hospitalizations from 2009, to 2019. Primary outcomes included ten-year comparative trends of the length of stay (LOS) and mean inpatient charges (MIC). Secondary outcomes included comparative mortality and LT rejection trends. Results There was a 14.05% decrease in CDI in LT hospitalizations over the study period (P = 0.05). The trend in LOS did not significantly vary (P = 0.9). MIC increased significantly over last decade in LT hospitalizations with CDI (P < 0.001). LT hospitalizations of autoimmune etiology compared against non-autoimmune did not increase association with CDI, adjusted odds ratio (aOR) 0.97 [95% confidence interval (CI) 0.75-1.26, P = 0.87]. CDI was associated with increased mortality in LT hospitalizations, aOR 1.84 [95% confidence interval (CI) 1.52-2.24, P < 0.001].  In-hospital mortality for LT hospitalizations with CDI decreased by 7.75% over the study period (P = 0.3). CDI increased transplant rejections, aOR 1.3 [95% CI 1.08-1.65, P < 0.001]. There was a declining trend in transplant rejection for LT hospitalization with CDI from 5% to 3% over the study period (P = 0.0048). Conclusion CDI prevalence doesnot increase based on autoimmune LT etiology. It increases mortality in LT hospitalizations; however, trend for mortality and transplant rejections has been declining over the last decade. This article is protected by copyright.
