ABSTRACT

BACKGROUND: Military general surgeons commonly perform urologic procedures, yet, there are no required urologic procedural minimums during general surgery residency training. Additionally, urologists are not included in the composition of forward operating surgical units. Urologic Care Army/Air Force/Navy Provider Education was created to provide military general surgeons with training to diagnose and treat frequently encountered urologic emergencies when practicing in environments without a urologist present.

STUDY DESIGN: A literature review and needs assessment were conducted to identify diagnoses and procedures to feature in the course. The course included a 1-hour didactic session and then a 2-hour hands-on simulated skills session using small, lightweight, cost-effective simulators. Using a pretest-posttest design, participants completed confidence and knowledge assessments before and after the course. The program was granted educational exemption by the institutional review board.

RESULTS: Twenty-seven learners participated. They demonstrated statistically significant improvement on the knowledge assessment (45.4% [SD 0.15] to 83.6% [SD 0.10], P < .01). On the confidence assessment, there were statistically significant (P ≤ .001) improvements for identifying phimosis, paraphimosis, and testicular torsion, as well as identifying indications for suprapubic catheterization, retrograde urethrogram, and cystogram. There were also statistically significant (P < .001) improvements for performing: suprapubic catheterization, dorsal penile block, dorsal slit, scrotal exploration, orchiopexy, orchiectomy, retrograde urethrogram, and cystogram.

CONCLUSION: We created the first-ever urologic emergencies simulation curriculum for military general surgeons that has demonstrated efficacy in improving the diagnostic confidence, procedural confidence, and topic knowledge for the urologic emergencies commonly encountered by military general surgeons.

ABSTRACT

INTRODUCTION: Despite the advances toward gender parity in medicine, a gap exists in the recognition of women physicians at academic and subspecialty medical conferences as plenary speakers and award winners. Conferences are cornerstones in the practice of medicine because they serve as platforms to showcase physicians’ successes and disseminate work. The selection of who is honored at such events can impact an individual’s career by creating networks that may lead to future opportunities. Additionally, the trend of who is honored may create expectations in the minds of trainees and early career physicians about what qualities help an individual achieve success. Our group sought to determine whether there was a gender gap in award recognition and speakership opportunities at the American College of Physicians (ACP) annual military chapter meetings.

METHODS: This was a cross-sectional study with data extracted from publicly available conference programs for the Army-Air Force annual ACP meetings and the Navy annual ACP meetings. Five years of data erewere reviewed for invited plenary speakers. Ten years of data were reviewed for award recipients. For an award to be included, it had to have a preset description and criteria for recipient selection. Awards not given annually or awards given for less than 3 years were excluded. Individuals’ gender was determined based on the first name and confirmed through internet searches of pronoun descriptors from professional websites. Comparisons were done using Fisher’s exact test and chi-square tests when appropriate, with statistical significance set at a two-tailed P-value of <.05.

RESULTS: Women comprised 26-30% of the chapter membership and there was no significant difference in gender distribution between the chapters. Fourteen of the 69 plenary speakers were women (20%), with significantly fewer women presenters in the Navy as compared to men. Thirty-six of the 134 award winners were women (27%), which was not significantly different from the overall chapter gender distributions. While women recipients of lifetime, teaching, research, and medical student awards were not significantly different from chapter gender distribution, women faculty were significantly more likely to receive an award for teaching than for research, with women receiving 13 of the 28 teaching awards (41%), and none of the 10 faculty research awards.

CONCLUSIONS: The military chapter ACP meetings reviewed mirrored civilian data in many ways, although military plenary speaker and award recipient distributions were more representative of the gender distribution of the branches. Review of the nomination process, planning committee selection, and opportunities for diversity training could be optimized to ensure that future conferences have a gender-balanced representation of individuals being honored. Improving upon current practices is important for the growth and retention of women military physicians.

ABSTRACT

INTRODUCTION: The aim of this study is to investigate a possible association between vitamin D deficiency and diabetic peripheral neuropathy in pediatric patients with type 1 diabetes mellitus.

MATERIALS-METHODS: Twenty-nine patients with type 1 diabetes mellitus and 19 healthy controls were included to the study. All individuals were evaluated for diabetic peripheral neuropathy with nerve conduction studies. Complete blood cell count, biochemical investigations, serum vitamin D levels, hemoglobin A1c levels were recorded.

RESULTS: No statistically significant differences between the diabetes and control groups in terms of gender, age, body weight, height, body mass index, systolic and diastolic blood pressures, laboratory investigations, serum vitamin D levels and nerve conduction studies was found. Patients with diabetes were grouped as patients with normal serum vitamin D levels and patients with vitamin D deficiency. Sensory nerve action potential of sural nerve and motor peroneal nerve velocity were statistically significantly lower in diabetic patients with vitamin D deficiency compared to diabetic patients with normal vitamin D levels (p 0.009 and 0.005 respectively).

CONCLUSION: Our results suggested that hypovitaminosis D might lead to development of neuropathic changes particularly on the lower limb nerves even in the early stages of the disease. It should be kept in mind that patients with hypovitaminosis D should be elaborately examined and closely followed up for the development of diabetic neuropathic changes, even if glucose control is achieved.

ABSTRACT

The Cancer of the Bladder Risk Assessment (COBRA) score is a predictive tool for estimating Cancer Specific Survival (CSS) after Radical Cystectomy (RC) for urothelial carcinoma. COBRA score variables are: age at RC, Tumor stage and Lymph Node Density (LND). We sought to externally validate the COBRA score and to improve its performance in estimating CSS adding Lymphovascular Invasion (LVI) as a further variable (Modified COBRA score). Clinicopathological and survival data from 789 patients who underwent RC and Pelvic Lymph Node Dissection (PLND) between January 2007 and December 2020 in two European referral centers (Paris, France and Badalona, Spain) were analyzed. COBRA score was applied to our cohort and CSS Kaplan-Meier curves were performed. Univariable and Multivariable analysis was performed in order to identify risk factors for Cancer Specific Mortality (CSM) and a score was assigned for any statistically significant risk factor; afterward, c-index calculation was performed and CCS curves have been plotted for the model after having integrated LVI variable to the COBRA score. Finally, we compared both COBRA score and Modified COBRA score models with the established AJCC model. A total of 789 patients underwent RC during the observation period. Complete data were available for 731 patients with a median follow-up of 32 months (8-47). CSM was 27.6% (no. 218 patients) at follow-up. When COBRA score was applied to our cohort, c-index was 0.76. Regression COX analysis has shown HR 0.36, CI 95% (0.16-0.83), P = .016 for patients with COBRA score 1; HR 0, CI 95% (0-1.77), P =.94 for score 2; HR 0.51, CI 95% (0.39 -0.67), P =.001 for score 3; HR 1.67, CI 95% (1.23-2.27), P =.001 for score 4; HR 2.45, CI 95% (1.51-3.99), P =.001 for score 5; HR 2.01, CI 95% (1.42-2.85), P =.001 for score 6 and HR 0.66, CI 95% (0.09-4.73), P =.682 for score 7. When the LVI variable was added to the CSS predictive model the discriminatory power increased to a c-index of 0.78. COBRA score adequately identifies those patients with a higher risk of CSM, with a c-index of 0.76. Moreover, LVI variable further improves its predictive accuracy from c-index of 0.76 to c-index of 0.78. LVI variable could be integrated in the COBRA score to optimizing prognosis stratification for patients who undergo RC.

ABSTRACT

PURPOSE: Identify the factors affecting father-infant attachment among Turkishs fathers of preterm infants.

DESIGN AND METHODS: This cross-sectional study included 63 fathers of preterm infants between the ages of 6-12 months. Data were collected using the Father-Infant Descriptive Information Form and the Paternal-Infant Attachment Scale (PIAS). Descriptive statistics, independent sample t-tests, mann-whitney test, the kruskal wallis test, the tamhane test, spearman correlation analysis, and linear stepwise regression were used to evaluate the data.

RESULTS: The average PIAS scores of the fathers in the study was 62.97 ± 8.94. A statistically significant difference was found between the birth weight, clinical picture, and length of stay in the Neonatal Intensive Care Unit (NICU) and PIAS total score of preterm infants (p < 0.01). There was a significant difference between the unplanned hospitalization of the baby after discharge and the father’s changing the baby’s clothes and the PIAS score (p < 0.05). Birth weight and unplanned hospitalization explained 31% of PIAS total score.

CONCLUSIONS: According to the results, father-infant attachment levels of fathers of preterm infants were low. Father’s involvement in changing the baby’s clothes, preterm birth weight, clinical picture, and length of stay in the NICU were found to be associated with PIAS.

PRACTICAL IMPLICATIONS: It should be remembered that babies can be attached to their fathers as much as they are to their mothers. NICU nurses should initiate father-infant interaction early and ensure fathers’ involvement in infant care in the NICU.

ABSTRACT

BACKGROUND: While population estimates suggest high vaccine effectiveness against SARS-CoV-2 infection, the protection for health care workers, who are at higher risk of SARS-CoV-2 exposure, is less understood.

METHODS: We conducted a national cohort study of health care workers in Wales (UK) from 7 December 2020 to 30 September 2021. We examined uptake of any COVID-19 vaccine, and the effectiveness of BNT162b2 mRNA (Pfizer-BioNTech) against polymerase chain reaction (PCR) confirmed SARS-CoV-2 infection. We used linked and routinely collected national-scale data within the SAIL Databank. Data were available on 82,959 health care workers in Wales, with exposure extending to 26 weeks after second doses.

RESULTS: Overall vaccine uptake was high (90%), with most health care workers receiving theBNT162b2 vaccine (79%). Vaccine uptake differed by age, staff role, socioeconomic status; those aged 50-59 and 60+ years old were 1.6 times more likely to get vaccinated than those aged 16-29. Medical and dental staff, and Allied Health Practitioners were 1.5 and 1.1 times more likely to get vaccinated, compared to nursing and midwifery staff. The effectiveness of the BNT162b2 vaccine was found to be strong and consistent across the characteristics considered; 52% three to six weeks after first dose, 86% from two weeks after second dose, though this declined to 53% from 22 weeks after the second dose.

CONCLUSIONS: With some variation in rate of uptake, those who were vaccinated had a reduced risk of PCR-confirmed SARS-CoV-2 infection, compared to those unvaccinated. Second dose has provided stronger protection for longer than first dose but our study is consistent with waning from seven weeks onwards.

ABSTRACT

PURPOSE: This study assessed the effect of mobile phone text message and call reminders in the completeness of the pentavalent vaccine administered against diphtheria, pertussis, tetanus, hepatitis B, and Haemophilus influenza.

DESIGN AND METHODS: The population for this quasi-experimental study were recent mothers of children not more than three weeks old selected from six local government areas of Kano State, Northern Nigeria. Three local government areas were each allocated to the intervention (reminder) and control groups of the study. Mobile phone reminders (SMS and follow-up calls) were sent to mothers in the reminder group three days to and on the due date of their child’s schedule for the 1st, 2nd and 3rd doses of the pentavalent vaccine. All statistical data were entered into the Statistical Package for Social Sciences (SPSS) version 23.0 and analysed using descriptive and inferential statistics.

RESULTS: A total of 541 mothers (271 in the intervention group and 270 in the control group) participated in the study. Completion rates for the three doses of the pentavalent vaccine were observed to be higher for children in the reminder group (n = 161, 59.4%) compared to those in the control group (n = 92, 34.1%).

CONCLUSION: Mobile phone reminders were effective and improved the rate of completeness of the pentavalent vaccine in the studied population. In line with the findings of the study, it is recommended that future studies should focus on identifying the best approach to remind parents either through SMS, phone calls, or voice messages or a combination of any of the approaches.

PRACTICE IMPLICATION: Nurses and other health care providers will have empirical evidence on the use of mobile phone technology to improve the health and wellbeing of children by protecting them from vaccine-preventable diseases.

ABSTRACT

STATEMENT OF PROBLEM: Knowledge of the effect of a shortened dental arch on masseter muscle thickness and occlusal force is sparse but could help clinicians understand how a shortened dental arch might affect the stomatognathic system.

PURPOSE: The purpose of this pilot clinical study was to evaluate and compare the masseter muscle thickness and occlusal force of participants rehabilitated by using a shortened dental arch with matched completely dentate individuals.

MATERIAL AND METHODS: Twelve partially edentulous participants with a minimum of 1 posterior occluding pair on each side of the arch were enrolled in the study. The mandibular arch of these participants was rehabilitated by using a single posterior mandibular implant crown (group S). The maxillary arch of all participants in group S was intact. Masseter muscle thickness (cm) and occlusal force (N) were recorded before (T1) and 6 months after implant rehabilitation (T2) for each participant. Twelve participants were selected as controls (group C). They were matched for age, sex, height, and weight with group S and evaluated for masseter muscle thickness and occlusal force. Masseter muscle thickness was evaluated by using ultrasonography during the rest position and maximum volumetric clenching. Occlusal force was measured with an occlusal force measuring appliance. All recordings were done for the left and right sides of the arch. Descriptive analysis was followed by comparison between groups and within group S by using the paired t test (α=.05).

RESULTS: Higher masseter muscle thickness and higher occlusal force were observed in group C than in group S before and after rehabilitation. An increase in masseter muscle thickness in the rest position and in maximum volumetric clenching was observed within group S after rehabilitation. Before rehabilitation, a difference in the masseter muscle thickness between group S and group C was statistically significant for the left side at the rest position (P=.017) and during maximum volumetric clenching (P=.016). After rehabilitation, the difference between group S and group C was not statistically significant for masseter muscle thickness at the rest position (P=.890 for right side and P=.555 for left side) and during maximum volumetric clenching (P=.109 for right side and P=.755 for left side). The difference in occlusal force between group S and group C was statistically significant for the right side and left side (P<.001) before rehabilitation and statistically not significant after rehabilitation (P=.161 for the right side and P=.134 for the left side).

CONCLUSIONS: Rehabilitation following the concept of a shortened dental arch increased masseter muscle thickness and occlusal force in partially edentulous individuals, making the masseter muscle thickness and occlusal force comparable with those of a completely dentate arch.

ABSTRACT

PURPOSE: Auditory nerve injury is one of the most common nerve injury complications of skull base fractures. However, there is currently a lack of auxiliary examination methods for its direct diagnosis. The purpose of this study was to find a more efficient and accurate means of diagnosis for auditory nerve injury.

METHODS: Through retrospectively analyzing the results of brainstem auditory evoked potential (BAEP) and high-resolution CT (HRCT) in 37 patients with hearing impairment following trauma from January 1, 2018 to July 31, 2020, the role of the two inspection methods in the diagnosis of auditory nerve injury was studied. Inclusion criteria were patient had a clear history of trauma and unilateral hearing impairment after the trauma; while exclusion criteria were: (1) severe patient with a Glasgow coma scale score ≤5 because these patients were classified as severe head injury and admitted to the intensive care unit, (2) patient in the subacute stage admitted 72 h after trauma, and (3) patient with prior hearing impairment before trauma. According to Goodman’s classification of hearing impairment, the patients were divided into low/medium/severe injury groups. In addition, patients were divided into HRCT-positive and negative groups for further investigation with their BAEP results. The positive rates of BEAP for each group were observed, and the results were analyzed by Chi-square test (p < 0.05, regarded as statistical difference).

RESULTS: A total of 37 patients were included, including 21 males and 16 females. All of them were hospitalized patients with GCS score of 6-15 at the time of admission. The BAEP positive rate in the medium and severe injury group was 100%, which was significantly higher than that in the low injury group (27.27%) (p < 0.01). The rate of BEAP positivitywas significantly higher in the HRCT-positive group (20/30, 66.7%) than in the negative group (1/7, 14.3%) (p < 0.05). Twenty patients (54.05%) were both positive for BEAP and HRCT test, and considered to have auditory nerve damage. Six patients (16.22%) were both negative for BEAP and HRCT test, and 10 patients (27.03%) were BAEP-negative but HRCT-positive: all the 16 patients were considered as non-neurological injury. The rest 1 case (2.70%) was BAEP-positive but HRCT-negative, which we speculate may have auditory nerve concussion.

CONCLUSION: By way of BAEP combining with skull base HRCT, we may improve the accuracy of the diagnosis of auditory nerve injury. Such a diagnostic strategy may be beneficial to guiding treatment plans and evaluating prognosis.

ABSTRACT

BACKGROUND: Acute kidney injury (AKI) is a common complication in patients undergoing liver transplantation (LT) for end-stage liver disease (ESLD), and renal replacement therapy (RRT) is required in many cases. This study was performed to identify the prognostic factors for patients undergoing RRT owing to AKI before living donor liver transplantation (LDLT).

MATERIALS AND METHODS: From January 2010 to December 2018, LDLT was performed in 464 adult patients in our center. We reviewed 33 patients who underwent RRT before LDLT among 464 consecutive cases. Patients who continued to RRT after LDLT or who underwent subsequent kidney transplantation were considered to have not recovered from renal impairment.

RESULTS: Among 33 patients, there were 23 patients in the recovery group and 10 patients in the nonrecovery group. The preoperative duration of RRT was shorter in the recovery group, but it was not statistically significant. In the nonrecovery group, diabetes mellitus was found to have a higher prevalence and ischemic time was longer. Other perioperative factors were not significantly different between the 2 groups. After LDLT, the peak total bilirubin level was higher, and the intensive care unit stay was longer in the nonrecovery group. The overall survival rate was higher in the recovery group.

CONCLUSIONS: Liver transplant recipients who maintain RRT after LDLT have poor outcome. It is necessary to know the risk factors and manage them well, perioperatively.
