ABSTRACT

BACKGROUND: The cesarean delivery rate has been rising in recent years, having associated maternal morbidities. Elective induction of labor has also been seen to rise during this same time period.

OBJECTIVE: This current study investigated the difference in the cesarean delivery rate between induction of labor and spontaneous labor among nulliparous, term, singleton, and vertex-presenting women.

STUDY DESIGN: A retrospective cohort in a single institution over a seven-year period was used for this analysis, observing the difference in cesarean delivery rate at different term gestational ages and neonatal morbidity using the 5-minute Apgar score < 5.

RESULTS: A statistically significant difference was found in cesarean delivery rate between those women whose labor was induced and those whose labor began spontaneously, at each term gestational age of labor initiation (P < 0.001). The proportion of indications for induction was described (i.e. elective vs. medically-indicated), and no difference was found for neonatal morbidity between the groups analyzed, using the 5-minute Apgar score as the perinatal outcome measure.

CONCLUSION: A comparison was made between spontaneous and induced labor regarding the resultant cesarean delivery rate, and a significant difference was found favoring spontaneous labor. This should be considered when electing to deliver using an induction methodology for nulliparous women, especially when there are no medical indications for it.

ABSTRACT

OBJECTIVE: As the population ages, obliterative procedures (OP) are expected to become an increasingly important treatment option. The primary aim of this study was to evaluate vaginal and urinary symptoms 3 months after OP and peri- and postoperative complications. The secondary aim was to investigate long-term outcomes, including patient satisfaction, regret rate and the rate of symptomatic recurrent prolapse after OP. Another secondary aim was to evaluate the feasibility of performing OP under local anesthesia (LA) as increasingly more operations are performed under LA.

STUDY DESIGN: Retrospective study of 43 women who underwent OP during a 10-year period. Patients completed three prolapse questions from the International Consultation on Incontinence-Vaginal Symptoms (ICIQ-VS) and the International Consultation on Incontinence Questionnaire- Urinary Incontinence Short Form (ICIQ-UI SF) before undergoing surgery, 3 months postoperatively and at long-term follow-up. Records were reviewed for complications, use of anesthetics, recurrences, patient satisfaction and regret.

RESULTS: A Le Fort colpocleisis was performed in 31 (72 %) and a colpectomy in 12 (28 %) patients. At 3 months` follow-up, patients had a statistically significant improvement in vaginal symptoms. Twelve patients (46 %) became continent, compared with 14 (54 %) with remaining urinary incontinence (UI). There were no patients with de novo UI 3 months’ after surgery. Total complication rate was 4,6% (2/43). A symptomatic recurrent prolapse occurred in 4 patients (9.3 %). The satisfaction rate was 86 %. No patients reported regret choosing to have vaginal closure surgery. Twenty one (49 %) of the procedures were performed under local anesthesia with intravenous sedation.

CONCLUSION: Obliterative procedures are good surgical options for elderly women with a positive impact on vaginal and urinary symptoms, low complication and recurrence rate. Patients report high satisfaction and no regret over loss of sexual ability at longterm follow-up. OP under LA with intravenous sedation is a feasible and safe option.

ABSTRACT

INTRODUCTION: Extragonadal teratomas (EGTs) are rare and the commonest intra-abdominal subtype is omental. We present two cases: 1) a parasitic omental teratoma likely secondary to auto-amputation of an ovarian teratoma with subsequent omental reimplantation and 2) an omental immature teratoma likely due to parthenogenetic activation of displaced primordial germ cells. We subsequently conduct a systematic review to characterise EGTs.

METHODS: We sourced for English, peer-reviewed case reports of extragonadal teratomas in women and female adolescents aged 11 and above published from inception of each database through 31st June 2020 following PRISMA guidelines. Two authors reviewed each case for appropriateness and each case was graded for methodological quality utilising a modified Newcastle Ottawa Scale. PROSPERO Registration Number: CRD42020190131 RESULTS: Upon literature review between 1920-2020, from an initial screen of 818 articles, 67 articles were selected featuring 70 cases. One case featured an immature teratoma while the remaining were mature. Omental EGTs were the most common (56.5 %) followed by Pouch of Douglas and uterosacral ligament (23.2 %) and upper abdomen (14.5 %). There were statistically significant differences in EGT mean sizes between each location with the largest being in the upper abdomen (10.9 cm) and the smallest being in the adnexa or hernia (6.2 cm). Auto-amputation was deemed the commonest cause amongst omental EGTs (55.3 %) and Pouch of Douglas and uterosacral ligament EGTs (37.5 %) while 70 % of upper abdominal EGTs were likely due to displaced primordial germ cells. We characterise clinical features associated with each pathogenic mechanism and imaging characteristics of EGTs. Characterisation of EGT tumour marker profiles was limited as only 42.9 % of cases reported them but 19.2-25.0 % had raised tumour markers. The main risks are torsion, rupture, immature components and potential malignant change of the cell lines. Treatment is largely surgical. The mean size of EGTs approached laparoscopically and via laparotomy was 5.23 cm and 9.16 cm respectively.

CONCLUSIONS: While rare, EGTs should be considered when evaluating pelviabdominal masses with imaging characteristics consistent with teratomas. Confirmation is usually intraoperative and a laparoscopic approach is reasonable if there is good surgeon comfort and the size is about 5 cm.

ABSTRACT

OBJECTIVE: To characterize differences in disposition arrangement among rehab-eligible stroke patients at a Comprehensive Stroke Center before and during the COVID-19 pandemic.

MATERIALS AND METHODS: We retrospectively analyzed a prospective registry for demographics, hospital course, and discharge dispositions of rehab-eligible acute stroke survivors admitted 6 months prior to (10/2019-03/2020) and during (04/2020-09/2020) the COVID-19 pandemic. The primary outcome was discharge to an inpatient rehabilitation facility (IRF) as opposed to other facilities using descriptive statistics, and IRF versus home using unadjusted and adjusted backward stepwise logistic regression.

RESULTS: Of the 507 rehab-eligible stroke survivors, there was no difference in age, premorbid disability, or stroke severity between study periods (p>0.05). There was a 9% absolute decrease in discharges to an IRF during the pandemic (32.1% vs. 41.1%, p=0.04), which translated to 38% lower odds of being discharged to IRF versus home in unadjusted regression (OR 0.62, 95%CI 0.42-0.92, p=0.016). The lower odds of discharge to IRF persisted in the multivariable model (aOR 0.16, 95%CI 0.09-0.31, p<0.001) despite a significant increase in discharge disability (median discharge mRS 4 [IQR 2-4] vs. 2 [IQR 1-3], p<0.001) during the pandemic.

CONCLUSIONS: Admission for stroke during the COVID-19 pandemic was associated with a significantly lower probability of being discharged to an IRF. This effect persisted despite adjustment for predictors of IRF disposition, including functional disability at discharge. Potential reasons for this disparity are explored.

ABSTRACT

OBJECTIVE: The aim of this study was to synthesize and characterize an experimental primer containing cationic lipid nanoparticles (NPL-chitosan) and to evaluate its properties.

DESIGN: The NPL-chitosan were synthesized by emulsion and sonication method. The experimental primers were applied in dentin surface of fifty human molars. The experimental groups were: 1) application of commercial primer; 2) Primer containing 2% of Chlorhexidine (CHX) 3); Primer with 2% NPL-chitosan 4); Primer with 0.6 % of NPL-chitosan 5); Primer with 0.4 % of NPL-chitosan. A composite resin plateau was used for the analysis, where sections were made for making the dentin beams. The effect of experimental primer with cationic nanoparticles in the inhibition of matrix metalloproteinase (MMP) activity was carrying out by in situ zymography. For the Resin-Dentin Adhesive Strength and in situ Zymography analysis, was used the One-way analysis of variance (ANOVA) with significance level of 95 %.

RESULTS: Spherical NPL-chitosan presented size below 220 nm, polydispersity index of 0.179 and zeta potential positive and was stable over 75 days. These nanoparticles showed antibacterial activity agsainst S. mutans with MIC of the 0.4 % and MBC of 0.67 %. In the Microtensile Strength, no statistical difference was observed between the experimental groups (p = 0.9054). The in situ zymography assay showed that the group with 2% of NPL-chitosan presented higher inactivation activity of MMPs compared to the other groups (p < 0.05).

CONCLUSION: The experimental primer containing NPL-chitosan has antimicrobial activity, does not alter the adhesive resistance and inactivates MMPs present in dentin.

ABSTRACT

Spain has been one of the most affected regions by the COVID-19 worldwide, and Madrid its most affected city. In response to this, the Spanish government enacted a strict lockdown in late March 2020, that was gradually eased until June 2020. We explored differentials in mobility by area-level deprivation in the functional area of Madrid, before, during, and after the COVID-19 lockdown. We used cell phone-derived mobility indicators (% of the population leaving their area) from the National Institute of Statistics (INE), and a composite measure of deprivation from the Spanish Society of Epidemiology (SEE). We computed changes in mobility with respect to pre-pandemic levels, and explored spatial patterns and associations with deprivation. We found that levels of mobility before COVID-19 were slightly higher in areas with lower deprivation. The economic hibernation period resulted in very strong declines in mobility, most acutely in low deprivation areas. These differences weakened during the re-opening, and levels of mobility were similar by deprivation once the lockdown was completely lifted. Given the existence of important socioeconomic differentials in COVID-19 exposure, it is key to ensure that these interventions do not widen existing social inequalities.

ABSTRACT

Patients recovering from coronavirus disease 2019 (COVID-19) may not return to a pre-COVID functional status and baseline levels of healthcare needs after discharge from acute care hospitals. Since the long-term outcomes of COVID-19 can be more severe in patients with underlying cardiorespiratory diseases, we aimed at verifying the impact of a preexisting cardiorespiratory comorbidity on multidisciplinary rehabilitation in post-COVID-19 patients. We enrolled 95 consecutive patients referring to the Pulmonary Rehabilitation Unit of Istituti Clinici Scientifici Maugeri Spa SB, IRCCS of Telese Terme, Benevento, Italy after being discharged from the COVID-19 acute care ward and after recovering from acute COVID-19 pneumonia. Forty-nine of them were not suffering from underlying comorbidities, while 46 had a preexisting cardiorespiratory disease. Rehabilitation induced statistically significant improvements in respiratory function, blood gases and the ability to exercise both in patients without any preexisting comorbidities and in those with an underlying cardiorespiratory disease. Response to the rehabilitation cycle tended to be greater in those without preexisting comorbidities, but DLco%-predicted was the only parameter that showed a significant greater improvement when compared to the response in the group of patients with underlying cardiorespiratory comorbidity. This study suggests that multidisciplinary rehabilitation may be useful in post-COVID-19 patients regardless of the presence of preexisting cardiorespiratory comorbidities.

ABSTRACT

PURPOSE: To assess whether CT-based radiomics of the ablation zone (AZ) can predict local tumour progression (LTP) after thermal ablation for colorectal liver metastases (CRLM).

MATERIALS AND METHODS: Eighty-two patients with 127 CRLM were included. Radiomics features (with different filters) were extracted from the AZ and a 10 mm periablational rim (PAR)on portal-venous-phase CT up to 8 weeks after ablation. Multivariable stepwise Cox regression analyses were used to predict LTP based on clinical and radiomics features. Performance (concordance [c]-statistics) of the different models was compared and performance in an ‘independent’ dataset was approximated with bootstrapped leave-one-out-cross-validation (LOOCV).

RESULTS: Thirty-three lesions (26 %) developed LTP. Median follow-up was 21 months (range 6-115). The combined model, a combination of clinical and radiomics features, included chemotherapy (HR 0.50, p = 0.024), cT-stage (HR 10.13, p = 0.016), lesion size (HR 1.11, p = <0.001), AZ_Skewness (HR 1.58, p = 0.016), AZ_Uniformity (HR 0.45, p = 0.002), PAR_Mean (HR 0.52, p = 0.008), PAR_Skewness (HR 1.67, p = 0.019) and PAR_Uniformity (HR 3.35, p < 0.001) as relevant predictors for LTP. The predictive performance of the combined model (after LOOCV) yielded a c-statistic of 0.78 (95 %CI 0.65-0.87), compared to the clinical or radiomics models only (c-statistic 0.74 (95 %CI 0.58-0.84) and 0.65 (95 %CI 0.52-0.83), respectively).

CONCLUSION: Combining radiomics features with clinical features yielded a better performing prediction of LTP than radiomics only. CT-based radiomics of the AZ and PAR may have potential to aid in the prediction of LTP during follow-up in patients with CRLM.

ABSTRACT

BACKGROUND CONTEXT: The thoracic spine is a common location for vertebral fractures as well as instrumentation failure after long spinal fusion procedures. The association between those complications and bone mineral density (BMD) are well recognized. Due to the overlying sternum and ribs in the thoracic spine, projectional BMD assessment tools such as dual energy x-ray absorptiometry (DXA) are limited to the lumbar spine. Quantitative computed tomography circumvents several shortcomings of DXA and allows for level-specific BMD measurements. Studies comprehensively quantifying BMD of the entire thoracic spine in patients undergoing spine surgery are limited.

PURPOSE: The objective of this study was: 1) to assess the reliability of thoracic QCT measurements, 2) to determine possible level-specific BMD variation throughout the thoracic spine and 3) to assess the correlation between BMDs of the T1-T12 spinal levels.

STUDY DESIGN/SETTING: Cross-sectional observation study.

PATIENT SAMPLE: Patients undergoing spine surgery from 2016-2020 at a single, academic institution with available preoperative CT imaging of the thoracic spine were included in this study.

OUTCOME MEASURES: The outcome measure was BMD measured by QCT.

METHODS: Patients undergoing spine surgery from 2016-2020 at a single, academic institution with available preoperative CT imaging of the thoracic spine were included in this study. Subjects with previous instrumentation at any thoracic level, concurrent vertebral fractures, a Cobb angle of more than 20 degrees, or incomplete thoracic spine CT imaging were excluded. Asynchronous quantitative computed tomography (QCT) measurements of T1-T12 were performed. To assess inter- and intra-observer reliability, a validation study was performed on 120 vertebrae in 10 randomly selected patients. The interclass correlation coefficient (ICC) was calculated. A pairwise comparison of BMD was conducted and correlations between each thoracic level were evaluated. The statistical significance level was set at p<0.05.

RESULTS: 60 patients (men, 51.7%) met inclusion criteria. The study population was 90% Caucasian with a mean age of 62.2 years and a mean BMI of 30.2 kg/m². The inter- and intra-observer reliability of the thoracic QCT measurements was excellent (ICC of 0.97 and 0.97, respectively). The trabecular BMD was highest in the upper thoracic spine and decreased in the caudal direction (T1 = 182.3 mg/cm³, T2 = 168.1 mg/cm³, T3 = 163.5 mg/cm³, T4 = 164.7 mg/cm³, T5 = 161.4 mg/cm³, T6 = 152.5 mg/cm³, T7 = 143.5 mg/cm³, T8 = 141.3 mg/cm³, T9 = 143.5 mg/cm³, T10 = 145.1 mg/cm³, T11 = 145.3 mg/cm³, T12 = 133.6 mg/cm³). The BMD of all thoracic levels cranial to T6 was statistically higher than the BMD of all levels caudal to T6 (p < 0.001). Nonetheless, significant correlations in BMD among all measured thoracic levels were observed, with a Pearson’s correlation coefficient ranging from 0.74 to 0.97.

CONCLUSIONS: There is significant regional BMD variation in the thoracic spine depending on spinal level. This BMD variation might contribute to several clinically relevant phenomena. First, vertebral fractures occur most commonly at the thoracolumbar junction including T12. In addition to mechanical reasons, these fractures might be partially attributed to thoracic BMD that is lowest at T12. Second, the optimal upper instrumented vertebra (UIV) for stopping long fusions to the sacrum and pelvis is controversial. The BMD of surgically relevant upper thoracic stopping points (T2-T4) was significantly higher than the BMD of lower thoracic stopping points (T10-T12). Besides stress concentration at the relatively mobile lower thoracic segments, the low BMD at these levels might contribute to previously suggested higher rates of junctional failures with short fusions.

ABSTRACT

INTRODUCTION: Learning disabilities are due to genetic and/or neurobiological factors that alter brain functioning by affecting one or more cognitive processes related to learning. This study aimed to assess the efficacy of cognitive telerehabilitation in adolescents with learning disabilities to overcome the treatment problems related to the COVID-19 pandemic lockdown.

METHODS: Twenty-four patients diagnosed with Unspecified Learning Disability (mean ± SD age: 18.2 ± 2.9 years; 50% male) were enrolled in this study. The patients were assessed by a neuropsychological evaluation at the beginning and at the end of the program. All patients received cognitive treatment via a specific telehealth app to stimulate the cognitive skills related to learning. The treatment lasted four weeks, with a daily training (lasting up to 60 min), for five days a week.

RESULTS: Our young patients reported a statistically significant improvement in the main cognitive domains that are usually compromised in learning disabilities, including sustained and selective attention, shifting of attention, control of interference, memory and speed of information processing. Moreover, the patients showed a good usability and motivation during the training.

CONCLUSIONS: Our study has shown that telerehabilitation could be a valid tool for the rehabilitation of specific cognitive skills in adolescents with learning difficulties.
