Background: Vitamin D deficiency is a common challenge its consequences are studied to be related to diversity of other health concerns. The efficacy and safety in longevity of vitamin D3 B.O.N. 200,000 IU Intramuscular Injection were examined through investigator-initiated clinical trial. Methods: One-hundred and eight subjects between ages of 19 and 65 who showed vitamin D deficiency (serum 25(OH)D<20 ng/mL) were initially injected once and were checked every 3 months for the next 12 months for serum 25(OH)D and 1,25(OH)2D levels for the drug’s efficacy, and for other safety observations. The percentage of participants maintaining within the normal serum 25(OH)D range were analyzed. Participants who reduced in the serum level below 30 ng/mL during the regular visits were given additional injections. Results: All the subjects showed similar patterns of statistically significant improvements at all times. The percentage of participants remaining in the normal range was higher in the better compliance group. No serious adverse events or severe adverse reactions occurred. Conclusions Treatment of the vitamin D-deficient subjects with the injection of 200,000 IU vitamin D3 B.O.N. Intramuscular Injection induced a statistically significant increase in blood vitamin D concentration for 12 months demonstrating the clinical efficacy of the intervention. The higher percentage of the better compliance group being within normal ranges strengthens the evidence of the efficacy. No new adverse events or severe adverse events were associated with the injection, demonstrating its safety. Further studies to facilitate development of appropriate guidelines for interventions using vitamin D3 intramuscular injections will be desirable.

Methods: Patients aged ≥18 years who underwent lumbar fusion with a postoperative drain between 2017 and 2020 were included and grouped based on hospital readmission status, last 8-hour drain output (<40 mL cutoff), or drain duration (2 days cutoff). Total output of all drains, total output of the primary drain, drain duration in days, drain output per day, last 8-hour output, penultimate 8-hour output, and last 8-hour delta (last 8-hour output subtracted by penultimate 8-hour output) were collected. Continuous and categorical data were compared between groups. Multivariate logistic regression analysis and receiver operating characteristic (ROC) analysis were performed to determine whether drain variables can predict hospital readmission, postoperative blood transfusions, and postoperative anemia. Alpha was 0.05. Results: Our cohort consisted of 1,166 patients with 111 (9.5%) hospital readmissions. Results of regression analysis did not identify any of the drain variables as independent predictors of hospital readmission, postoperative blood transfusion, or postoperative anemia. ROC analysis demonstrated the drain variables to be poor predictors of hospital readmission, with the highest area under curve of 0.524 (drain duration), corresponding to a sensitivity of 61.3% and specificity of 49.9%. Conclusions Drain output or duration did not affect readmission rates following lumbar spine surgery.

Six months after undergoing reverse total shoulder arthroplasty (RSA) a 73-year-old woman sustained a periprosthetic scapular spine fracture following a fall. She was treated with open reduction and internal fixation (ORIF), followed by botulinum toxin injection into the deltoid muscle to temporarily minimize strain at the fracture. Fracture union was achieved by three months, with excellent clinical function more than one year following fracture fixation and full resolution of deltoid function. Scapular spine fracture following RSA can be treated with ORIF and temporary deltoid paralysis using botulinum toxin in the immediate postoperative period to safely support fracture healing.

Background: and Purpose High-grade carotid artery stenosis may alter hemodynamics in the ipsilateral hemisphere, but consequences of this effect are poorly understood. Cortical thinning is associated with cognitive impairment in dementia, head trauma, demyelination, and stroke. We hypothesized that hemodynamic impairment, as represented by a relative time-to-peak (TTP) delay on MRI in the hemisphere ipsilateral to the stenosis, would be associated with relative cortical thinning in that hemisphere. Methods: We used baseline MRI data from the NINDS-funded Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis–Hemodynamics (CREST-H) study. Dynamic contrast susceptibility MR perfusion-weighted images were post-processed with quantitative perfusion maps using deconvolution of tissue and arterial signals. The protocol derived a hemispheric TTP delay, calculated by subtraction of voxel values in the hemisphere ipsilateral minus those contralateral to the stenosis. Results: Among 110 consecutive patients enrolled in CREST-H to date, 45 (41%) had TTP delay of at least 0.5 seconds and 9 (8.3%) subjects had TTP delay of at least 2.0 seconds, the maximum delay measured. For every 0.25-second increase in TTP delay above 0.5 seconds, there was a 0.006-mm (6 micron) increase in cortical thickness asymmetry. Across the range of hemodynamic impairment, TTP delay independently predicted relative cortical thinning on the side of stenosis, adjusting for age, sex, hypertension, hemisphere, smoking history, low-density lipoprotein cholesterol, and preexisting infarction (P=0.032). Conclusions Our findings suggest that hemodynamic impairment from high-grade asymptomatic carotid stenosis may structurally alter the cortex supplied by the stenotic carotid artery.

Methods: Patients undergoing primary, elective 1–3 level ACDF for radiculopathy at a single academic center between 2015 and 2021 were identified retrospectively. Cervical FS was evaluated using axial T2-weighted MRI images via a validated grading scale. The maximum degree of stenosis was used for multilevel disease. Motor symptoms were classified using encounters at their final preoperative and first postoperative visits, with examinations ≤3/5 indicating weakness. PROMs were obtained preoperatively and at 1-year follow-up. Bivariate analysis was used to compare outcomes based on stenosis severity, followed by multivariable analysis. Results: This study included 354 patients, 157 with moderate stenosis and 197 with severe stenosis. Overall, 58 patients (16.4%) presented with upper extremity weakness ≤3/5. A similar number of patients in both groups presented with baseline motor weakness (13.5% vs. 16.55, p =0.431). Postoperatively, 97.1% and 87.0% of patients with severe and moderate FS, respectively, experienced full motor recovery (p =0.134). At 1-year, patients with severe neuroforaminal stenosis presented with significantly worse 12-item Short Form Survey Physical Component Score (PCS-12) (33.3 vs. 37.3, p =0.049) but demonstrated a greater magnitude of improvement (Δ PCS-12: 5.43 vs. 0.87, p =0.048). Worse stenosis was independently associated with greater ΔPCS-12 at 1-year (β =5.59, p =0.022). Conclusions Patients with severe FS presented with worse preoperative physical health. While ACDF improved outcomes and conferred similar motor recovery in all patients, those with severe FS reported much better improvement in physical function.

Background: Meningococcal meningitis is a disease that can cause severe and possibly fatal side effects. To prevent the spread of meningococcal meningitis, which is a highly transmissible disease, 16 states in the USA mandate entering college students to receive meningococcal vaccination. Nevertheless, South Korea does not. This study aims to point out the importance of meningococcal vaccination by comparing the level of general knowledge and recognition of the requirement for vaccination among university students in the USA/Canada and Korea. Methods: The study was conducted using a self-filled questionnaire survey targeting international and Korean students at one of Korea's universities. The survey focused on topics such as knowledge of infectious diseases that can occur at the dormitory residence, infectious agents and routes of meningococcal meningitis infection and infection route, and students' intention to receive meningococcal vaccination. Results: International university students had a higher awareness of the importance of infectious disease prevention than Korean students (P<0.05) and also had higher meningococcal-related knowledge (P<0.05).International universities strongly recommend meningococcal vaccination compared to Korean universities (P<0.05), and the actual vaccination rate was higher than that of domestic university students (P<0.05). Conclusions This study found that the awareness of meningococcal vaccination among Korean university students was lower than that of international university students, and the vaccination rate was also lower. Because students often do not get vaccinated due to low awareness of the meningococcal disease, health education programs can increase their knowledge about infectious diseases and awareness of vaccines. Thus, increasing the vaccination rate.

Objectives: Female sexual and reproductive health is heavily influenced by the levels and ratios of Lactobacilli species and vaginal cytokines. Menopause marks a profound body change as it shifts to a natural and permanent non-reproductive state. Vulvovaginal diseases encompass a broad variety of sexual health conditions. Furthermore, both menopause and vulvovaginal diseases affect vaginal Lactobacilli and cytokine levels. Thus, this study aimed to investigate the correlation between menopause, vulvovaginal diseases, and vaginal Lactobacilli and cytokine levels. Methods: Vaginal swab samples were collected as part of a prospective data bank creation to study vaginal conditions as approved by the Institutional Review Board of Texas Tech University Health Sciences Center, Lubbock, USA. This study utilized 38 samples in this database, which were assigned to the pre-menopausal with no vulvovaginal conditions (n = 20) and post-menopausal with vulvovaginal conditions (n = 18) groups. A real-time polymerase chain reaction was conducted to determine the relative concentration of Lactobacilli species, while cytokine analysis was performed using multiplex enzyme-linked immunosorbent assay immunoassay. The standardized mean difference, multivariate analysis of variance, and permutational unequal variance t test were used for the statistical analysis. Results: Cytokines, interleukin (IL)-6, macrophage inflammatory protein-1α, IL-8, and Lactobacillus iners expression were significantly elevated in the control group compared to the study group (P = 0.03 for the cytokines, P = 0.0194 for Lactobacilli). Conclusions The levels of vaginal cytokine and Lactobacillus profile were significantly different between the pre-menopausal and post-menopausal groups.

Objective: This paper presents a review of the current state of child and adolescent mental health literacy and provides current evidence of the economic impact of a pediatric mental health literacy (MHL) training program. Methods: Employing a case-series-comparison design, physician referrals to urgent and specialized mental health services were linked with patient-specific information comparing referrals from MHL participants and non-participating physicians. The economic impact analysis was based on changes in the admitted referral frequency and lengths of stay for the MHL group, compared to themselves pretraining, and over the same time period compared to non-participating physicians. Results: Average scheduled ambulatory admission rates per physician remained constant for trained and untrained pre-post groups. Average scheduled ambulatory admission wait time and length of stay reduced significantly post-training for MHL-trained physicians compared to pre-training and untrained physicians. In addition to reductions in length of stay, the total bed costs saving for emergency/ inpatients admission deferrals was $2,932,112 or about $20,000 per MHL-trained physician. Conclusion The estimated economic impact of the MHL training shows a substantial return on investment and supports wider implementation. The MHL training program should be a key feature of mental health reform strategies, as well as continuing and undergraduate medical education.

PURPOSE: Impending compartment syndrome is a common event following closed tibia fractures, which can progress to sinister compartment syndrome. Fasciotomy is the only definitive treatment available, though it has its own drawbacks and complications. Medical management at present consists of limb elevation and adequate hydration. This study aims at determining whether intravenous administration of Mannitol reduced the intracompartmental pressure in patients with closed tibial fractures. METHODS: This is a double blinded, randomized control trial done in a single tertiary care center in India. Forty-five patients were recruited between February 2012 and October 2012. Forty patients who presented to the emergency department with isolated, closed, high velocity, and proximal 2/3 tibia fractures were included in this study. Patients with contraindication to Mannitol were excluded. They were allocated into 2 groups by the investigator using computer generated randomization. The pressure in the anterior compartment of the leg was measured with a handheld Stryker pressure monitor. Then either 20% Mannitol or 0.9% normal saline as given intravenously in a blinded manner, based on the randomization. The intracompartmental pressure was measured at 0, 1 and 3 h after the infusion. The participant, investigator and statistician were masked to the group assessment. RESULTS: There was no difference in intracompartmental pressures at 1 or 3 h, between the groups. However, in patients with the baseline of compartmental pressures ≥30 mmHg, Mannitol showed a marked reduction in pressure of 8.5 mmHg at 1 h compared to almost no change in pressure in the saline group. There were no adverse events with the use of Mannitol. CONCLUSIONS This preliminary study appears to show that Mannitol is useful in the management of the increased compartment pressure. The limitations of this study were that it only involved a small group of patients and the baseline pressures in both the groups were not comparable. More studies are required before the use of Mannitol as a standard of care in the management of compartment syndrome can be established.
