Background: Defective thyroid functioning is referred to as dysthyroidism. Despite incomplete thyroidectomy or thyroxine supplementation, post-thyroidectomy patients may still experience dysthyroidism. Many times, this may be sub - clinical. This study aimed to assess the prevalence and pattern of sub-clinical dysthyroidism following thyroid surgery. Methods: In this prospective cohort study, 40 patients were consecutively recruited following conventional thyroidectomy and followed up to 12months. All patients were euthyroid at surgery. At 12 months serum TSH, T4 and T3 levels were measured and the patients clinically assessed. The prevalence and pattern of dysthyroidism was analysed statistically against the patient demographics, clinical and peri-operative variables for significance, using stata version 13. The confidence interval was at 95% and the statistical significance at a p-value of <0.05. Results: The mean age was 44.3 years (M:F= 1: 12.3). 20% of the patients had medical comorbidities. The types of surgery performed were sub-total thyroidectomy (55%), near total thyroidectomy (25%) and total thyroidectomy (20%). The prevalence of postoperative dysthyroidism was 52.5%. 22.7% of patients who underwent sub-total thyroidectomy had dysthyroidism. Most patients (90%) who were on thyroxine supplement (following total or near total thyroidectomy) still developed dysthyroidism (P= 0.017). The type of resection done had the greatest significance (P= 0.000). Other factors associated with dysthyroidism albeit non-significantly were history of pre-operative hyperthyroidism, middle age (40 - 60 years), and female gender. Conclusions: The prevalence of dysthyroidism in this cohort was high which may reflect the broader picture among post - thyroidectomy patients in this setting. Regular biochemical testing in post-thyroidectomy patients is important to identify and correct dysthyroidism early. This requires frequent follow-up and accurate dose adjustment, based on objective assessments like weight or body mass index. Keywords: post-thyroidectomy; dysthyroidism; hypothyroidism; hyperthyroidism; sub-clinical dysthyroidism; prospective; cohort

Study Design: This was a prospective cohort study. Objectives: To introduce the iliac connectors as fixation options in spinal constructs used for correction of severe scoliosis at locations other than the lumbopelvic region. Methods: Nine patients with severe rigid scoliosis undergoing surgical release and posterior instrumentation in the period between January 2013 and January 2015 were included in this prospective cohort study. Mean age was 18.4 years; 8 had triple structural curves, and the remaining patient had double structural curves. Cobb angles of the primary and compensatory curves were compared with the immediate, 1-year, and 2-year postoperative measurements using the F test, with P value ≤.05 indicating statistical significance. Screw densities of the final constructs were calculated and compared with the screw densities when the offset iliac connectors were not used. Results: One to 4 offset iliac connectors were used in all 9 patients, increasing screw density by a mean of 6.24 ( P < .001). The mean Cobb angle of the major curve was corrected from 98.44° to 58.2° ( P < .001), that of the first compensatory curve, from 56.55° to 38.33° ( P < .001), and that of the second compensatory curve, from 40.75° to 26.63° ( P < .001). There were no intraoperative neurological complications. After a mean follow-up of 30.6 months, the construct remained stable in all patients with no loss of correction. Conclusion: Offset iliac connectors can be a valuable tool to increase screw density in correction of severe scoliosis, thus increasing overall biomechanical strength of the final construct.

<b><i>Background:</i></b> Vismodegib has shown clinical efficacy in the management of locally advanced basal cell carcinomas (laBCC). However, non-response to vismodegib is observed in 2–13.5% of patients in clinical studies. The purpose of this study was to identify factors associated with non-response to vismodegib in patients with laBCC. <b><i>Methods:</i></b> We carried out a retrospective multicenter study, including patients with laBCC treated with vismodegib, from July 2011 to May 2019. Response to treatment was assessed according to the RECIST 1.1 criteria. Patients were categorized as responders with a complete response or a partial response or non-responders with a stable disease or a progressive disease according to what has been observed during follow-up. Patient demographics, tumor profile, and treatment modalities were compared in responders and non-responders. <b><i>Results:</i></b> Eighty-three patients with laBCC were included in the study. Twenty-five (30.1%) were non-responders to vismodegib. History of treatment with radiotherapy, presence of muscle involvement and intermittent treatment with vismodegib were significantly associated with a non-response (<i>p</i> &#x3c; 0.001, <i>p</i> = 0.025, <i>p</i> &#x3c; 0.001). Bone involvement (<i>p</i> = 0.2) and morpheaform IaBCC subtype (<i>p</i> = 0.056) were more frequent in non-responders without reaching statistical significance. <b><i>Conclusion:</i></b> In this study, non-response of laBCC to vismodegib therapy was associated with muscle involvement. Previous radiotherapy and intermittent use of vismodegib have been identified as causes favoring non-response to vismodegib. Due to the low numbers of patients included in the study, it is difficult to draw firm conclusions. Further studies are needed to confirm these data.

Post-traumatic stress disorder (PTSD) is a prevalent mental disorder marked by psychological and behavioral changes. Currently, there is no consensus of preferred antipsychotics to be used for the treatment of PTSD. We aim to discover whether certain antipsychotics have decreased suicide risk in the PTSD population, as these patients may be at higher risk. A total of 38,807 patients were identified with a diagnosis of PTSD through the ICD9 or ICD10 codes from January 2004 to October 2019. An emulation of randomized clinical trials was conducted to compare the outcomes of suicide-related events (SREs) among PTSD patients who ever used one of eight individual antipsychotics after the diagnosis of PTSD. Exclusion criteria included patients with a history of SREs and a previous history of antipsychotic use within one year before enrollment. Eligible individuals were assigned to a treatment group according to the antipsychotic initiated and followed until stopping current treatment, switching to another same class of drugs, death, or loss to follow up. The primary outcome was to identify the frequency of SREs associated with each antipsychotic. SREs were defined as ideation, attempts, and death by suicide. Pooled logistic regression methods with the Firth option were conducted to compare two drugs for their outcomes using SAS version 9.4 (SAS Institute, Cary, NC, USA). The results were adjusted for baseline characteristics and post-baseline, time-varying confounders. A total of 5294 patients were eligible for enrollment with an average follow up of 7.86 months. A total of 157 SREs were recorded throughout this study. Lurasidone showed a statistically significant decrease in SREs when compared head to head to almost all the other antipsychotics: aripiprazole, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (p < 0.0001 and false discovery rate-adjusted p value < 0.0004). In addition, olanzapine was associated with higher SREs than quetiapine and risperidone, and ziprasidone was associated with higher SREs than risperidone. The results of this study suggest that certain antipsychotics may put individuals within the PTSD population at an increased risk of SREs, and that careful consideration may need to be taken when prescribed.

IntroductionWe sought to investigate the relationship between serum 25-hydroxyvitamin D (25(OH)D) level and the risk of type 2 diabetes mellitus (T2DM) in adults who participated in the Trøndelag Health Study (HUNT), and the possible effect modification by family history and genetic predisposition.Research design and methodsThis prospective study included 3574 diabetes-free adults at baseline who participated in the HUNT2 (1995–1997) and HUNT3 (2006–2008) surveys. Serum 25(OH)D levels were determined at baseline and classified as <50 and ≥50 nmol/L. Family history of diabetes was defined as self-reported diabetes among parents and siblings. A Polygenic Risk Score (PRS) for T2DM based on 166 single-nucleotide polymorphisms was generated. Incident T2DM was defined by self-report and/or non-fasting glucose levels greater than 11 mmol/L and serum glutamic acid decarboxylase antibody level of <0.08 antibody index at the follow-up. Multivariable logistic regression models were applied to calculate adjusted ORs with 95% CIs. Effect modification by family history or PRS was assessed by likelihood ratio test (LRT).ResultsOver 11 years of follow-up, 92 (2.6%) participants developed T2DM. A higher risk of incident T2DM was observed in participants with serum 25(OH)D level of<50 nmol/L compared with those of ≥50 nmol/L (OR 1.72, 95% CI 1.03 to 2.86). Level of 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in adults without family history of diabetes (OR 3.87, 95% CI 1.62 to 9.24) but not in those with a family history (OR 0.72, 95% CI 0.32 to 1.62, p value for LRT=0.003). There was no effect modification by PRS (p value for LRT>0.23).ConclusionSerum 25(OH)D<50 nmol/L was associated with an increased risk of T2DM in Norwegian adults. The inverse association was modified by family history of diabetes but not by genetic predisposition to T2DM.

Abstract BACKGROUND The current gold standard for evaluation of the surgical result after intracranial aneurysm (IA) clipping is two-dimensional (2D) digital subtraction angiography (DSA). While there is growing evidence that postoperative 3D-DSA is superior to 2D-DSA, there is a lack of data on intraoperative comparison. OBJECTIVE To compare the diagnostic yield of detection of IA remnants in intra- and postoperative 3D-DSA, categorize the remnants based on 3D-DSA findings, and examine associations between missed 2D-DSA remnants and IA characteristics. METHODS We evaluated 232 clipped IAs that were examined with intraoperative or postoperative 3D-DSA. Variables analyzed included patient demographics, IA and remnant distinguishing characteristics, and 2D- and 3D-DSA findings. Maximal IA remnant size detected by 3D-DSA was measured using a 3-point scale of 2-mm increments. RESULTS Although 3D-DSA detected all clipped IA remnants, 2D-DSA missed 30.4% (7 of 23) and 38.9% (14 of 36) clipped IA remnants in intraoperative and postoperative imaging, respectively (95% CI: 30 [ 12, 49] %; P-value .023 and 39 [23, 55] %; P-value = &lt;.001), and more often missed grade 1 (&lt; 2 mm) clipped remnants (odds ratio [95% CI]: 4.3 [1.6, 12.7], P-value .005). CONCLUSION Compared with 2D-DSA, 3D-DSA achieves a better diagnostic yield in the evaluation of clipped IA. Our proposed method to grade 3D-DSA remnants proved to be simple and practical. Especially small IA remnants have a high risk to be missed in 2D-DSA. We advocate routine use of either intraoperative or postoperative 3D-DSA as a baseline for lifelong follow-up of clipped IA.

Background: Decision to undertake total thyroidectomy when gross inspection of the gland raises suspicion of widespread degenerative changes is often intraoperative. Knowing the factors associated with intraoperative conversion to total thyroidectomy may assist preoperative counselling. This study describes the probability of conversion to total thyroidectomy and factors associated with con-version among patients hitherto planned for partial thyroidectomy. Methods: We reviewed 191 records and extracted data on patient demographics, the pre-operative radiograph findings, the weight of excised gland and the operation performed. Descriptive and inferential statistics were performed. Receiver operator curve was used to assess for cut-off point. P-value was set at 0.05. Results: A total of 191 records was reviewed consisting of 181 females (94.8% 95% CI 90.6-97.5) and 10 males (5.2%, 95%CI 2.5-9.4). Only nodular goiters required conversion to total thyroidectomy. The over-all probability of total thyroidectomy was 11%(95% CI 7.0-16.3). The probability of total thyroidectomy in female was 10.5%(95% CI 6.4-16.9) while in male was 20%(95% CI2.5-55.6). The probability of total thyroidectomy in a female with nodular goiter was 8.1%(95% CI 4.8-13.5), compared to 28.6%(95% CI 3.7-71) in males. The risk of total thyroidectomy was associated with the weight of the excised gland. Conclusion: Only nodular goiters required intraoperative conversion to total thyroidecto-my and the probability of conversion was higher in males.

336 Background: The potential role of ctDNA to identify residual disease after potentially curative resection has been suggested in some malignancies; its role in resected pancreatico(P)-biliary(B) malignancies is unknown. Methods: Patients diagnosed with PB malignancies underwent molecular profiling (ctDNA) using FoundationMedicine Liquid (72 cancer-related genes) following potentially curative resection. Baseline patient characteristics and molecular profiling outcomes, including mutant allele frequency (MAF) for pathological alterations were extracted. Primary objective: prevalence of ctDNA identification and its correlation with recurrence (relapse-free survival (RFS) and relapse rate). Results: Total of 11 individuals had ctDNA analysed following potentially curative resection for PB malignancies: 8 B (4 extra-hepatic cholangiocarcinoma (eCCA), 2 ampulla, 1 intrahepatic cholangiocarcinoma (iCCA), 1 gallbladder cancer (GBC)) and 3 P. Baseline characteristics: 6 female (54.55%), median age 71.59 years (range 39.98-81.19). Most were pT2 (45.45%), pN0 (54.55%) and R0 (63.64%). Following surgery, 6 patients were started on adjuvant chemotherapy; at the end of follow-up (data cut-off 25/6/2020; median follow-up 11.15 months (range 5.45-13.52); 5 relapsed (45.45%) and 2 died (18.18%). Estimated median RFS was 11.43 months (95% CI 2.28-not reached); median overall survival was not reached. No sample failed ctDNA analysis; presence of ctDNA was identified in 3/11 (27.27%) of the samples; 2 and 1 samples had 2 and 1 pathological alterations identified, respectively: ALK fusion (1 sample; GBC), TP53 mutation (2 samples; eCCA and GBC), CHEK2 mutation (1 sample; pancreas), IDH2 mutation (1 sample; eCCA). Mean maximum MAF was 1.47 (2 in biliary; 0.43 in pancreas). Variants of unknown significance were identified in 72.73% of the samples (87.5% in B; 33.33% in P; p-value 0.152). None of the baseline characteristics explored correlated with presence of ctDNA. There was a trend towards increased relapse risk in the patients with ctDNA present following potentially curative surgery; Cox regression for RFS [HR 2.64 (95% CI 0.36-19.31); median RFS 11.44 months (95% CI 2.28-not reached) vs 10.87 (95% CI 2.21-not reached)]; relapse rate 37.5% (ctDNA absent) vs 66.67% (ctDNA present); statistical significance was not reached (p-value 0.340 and p-value 0.545, respectively). Conclusions: This pilot study demonstrates the feasibility of testing for ctDNA following potentially curative resection in PB malignancies. Presence of ctDNA may be associated with increased relapse risk; further studies are required to increase sample size and assess clinical implications.

At baseline, borderline patients reported higher rates of adult rape and physical assault by a partner than Axis II comparison subjects. Four risk factors were found to significantly predict whether borderline patients had an adult history of being a victim of physical and/or sexual violence before their index admission: female gender, a substance use disorder that began before the age of 18, childhood sexual abuse, and emotional withdrawal by a caretaker (a form of neglect). At six-year and 10-year follow-up, borderline patients reported higher rates of being verbally, emotionally, physically, and sexually abused or assaulted than did Axis II comparison subjects. However, each of these forms of abuse declined significantly over time. The clinical implications of these prevalence and predictive findings are discussed.

AbstractKnee range of motion (ROM) is an important postoperative measure of total knee arthroplasty (TKA). There is conflicting literature whether patients who are obese have worse absolute ROM outcomes than patients who are not obese. This study analyzed whether preoperative body mass index (BMI) influences knee ROM after patients' primary TKA. A retrospective investigation was performed on patients, who underwent primary TKA at an academic institution, by one of three fellowship-trained adult reconstruction surgeons. Patients were stratified according to their preoperative BMI into nonobese (BMI < 30.0 kg/m2) and obese (BMI ≥ 30.0 kg/m2) classifications. Passive ROM was assessed preoperatively as well as postoperatively at patients' most recent follow-up visit that was greater than 2 years. Mann–Whitney U tests were performed to determine statistical significance at p-value <0.05 for ROM outcomes. No statistically significant differences were observed when ROM in the nonobese group was compared with ROM in the obese group both preoperatively (105.73 ± 11.58 vs. 104.14 ± 13.58 degrees, p-value = 0.417) and postoperatively (105.83 ± 14.19 vs. 104.49 ± 13.52 degrees, p-value = 0.777). Mean follow-up time for all patients was 4.49 ± 1.92 years. In conclusion, long-term postoperative ROM outcomes were similar between patients who were nonobese and patients who were obese.

Abstract Background There are limited data on the natural history of antenatal Zika virus (ZIKV) exposure in twin pregnancies, especially regarding intertwin concordance of prenatal, placental, and infant outcomes. Methods This prospective cohort study included twin pregnancies referred to a single institution from September 2015 to June 2016 with maternal ZIKV. Polymerase chain reaction (PCR) testing of maternal, placental, and neonatal samples was performed. Prenatal ultrasounds were completed for each twin, and histomorphologic analysis was performed for each placenta. Abnormal neonatal outcome was defined as abnormal exam and/or abnormal imaging. Two- to three-year follow-up of infants included physical exams, neuroimaging, and Bayley-III developmental assessment. Results Among 244 pregnancies, 4 twin gestations without coinfection were identified. Zika virus infection occurred at 16–33 weeks gestation. Zika virus PCR testing revealed discordance between dichorionic twins, between placentas in a dichorionic pair, between portions of a monochorionic placenta, and between a neonate and its associated placenta. Of the 8 infants, 3 (38%) had an abnormal neonatal outcome. Of 6 infants with long-term follow-up, 3 (50%) have demonstrated ZIKV-related abnormalities. Conclusions Neonatal PCR testing, placental findings, and infant outcomes can be discordant between co-twins with antenatal ZIKV exposure. These findings demonstrate that each twin should be evaluated independently for vertical transmission.
