Ex-utero intrapartum treatment has been established as an option for fetal and perinatal surgeons to deliver patients with sacrococcygeal teratomas (SCTs) which are causing significant fetal distress ...and possible in-utero fetal demise. However, ex-utero intrapartum treatment procedures carry significant maternal risk and morbidity. Herein, we report an alternative technique of Cesarean section to immediate resection (CSIR) for managing high-risk SCTs.
A retrospective institutional review board–approved review was performed on all SCTs evaluated at our fetal center from May 2014 to September 2020. Demographics; prenatal imaging characteristics; prenatal interventions; and postnatal surgery data including operative time, estimated blood loss, pathology, and outcomes were collected. Outcomes of interest included surveillance serum alpha-fetoprotein levels, imaging surveillance, developmental milestones, and the presence or absence of constipation or fecal incontinence.
A total of 20 patients with prenatal diagnosis of SCT were evaluated. Mothers who transferred their care to another institution after diagnosis were excluded from this study. Twelve neonates underwent standard postnatal resection. Three neonates underwent emergent CSIR for high output cardiac failure, fetal anemia, or concerns for in-utero hemorrhagic rupture. The median (interquartile range) operative time was 231.5 (113) minutes for the standard operative group versus 156 min in the CSIR group. We present three patients who underwent immediate resection after emergent Cesarean section. We report 100% survival for the three consecutive cases.
CSIR is a safe and feasible approach for managing appropriately selected high-risk SCTs with signs of hydrops, fetal distress, or fetal anemia. Despite patient prematurity, we demonstrated 100% survival of three consecutive cases. We suggest that CSIR be considered an option in the management algorithm for high-risk SCTs.
Low or high prepregnancy body mass index (BMI) and inadequate or excess gestational weight gain (GWG) are associated with adverse neonatal outcomes. This study estimates the contribution of these ...risk factors to preterm births (PTBs), small-for-gestational age (SGA) and large-for-gestational age (LGA) births in Canada compared to the contribution of prenatal smoking, a recognized perinatal risk factor.
We analyzed data from the Canadian Maternity Experiences Survey. A sample of 5,930 women who had a singleton live birth in 2005-2006 was weighted to a nationally representative population of 71,200 women. From adjusted odds ratios, we calculated population attributable fractions to estimate the contribution of BMI, GWG and prenatal smoking to PTB, SGA and LGA infants overall and across four obstetric groups.
Overall, 6% of women were underweight (<18.5 kg/m(2)) and 34.4% were overweight or obese (≥25.0 kg/m(2)). More than half (59.4%) gained above the recommended weight for their BMI, 18.6% gained less than the recommended weight and 10.4% smoked prenatally. Excess GWG contributed more to adverse outcomes than BMI, contributing to 18.2% of PTB and 15.9% of LGA. Although the distribution of BMI and GWG was similar across obstetric groups, their impact was greater among primigravid women and multigravid women without a previous PTB or pregnancy loss. The contributions of BMI and GWG to PTB and SGA exceeded that of prenatal smoking.
Maternal weight, and GWG in particular, contributes significantly to the occurrence of adverse neonatal outcomes in Canada. Indeed, this contribution exceeds that of prenatal smoking for PTB and SGA, highlighting its public health importance.
The surgeon–scientist brings a unique perspective to surgical research. The Association of Academic Surgeons and Society of University Surgeons foster the development of surgeon–scientists through ...foundation awards to residents and junior faculty. We sought to evaluate the academic success of surgeons who received an Association for Academic Surgery/Society of University Surgeons award.
Information was collected for individuals who received a resident or junior faculty research award from the Association for Academic Surgery or Society of University Surgeons. Google Scholar, Scopus, and the National Institutes of Health Research Portfolio Online Reporting Tools: Expenditures and Results were used to assess scholarly achievements.
Eighty-two resident awardees were included, 31 (38%) of whom were female. Thirteen (24%) are now professors, 12 (22%) are division chiefs, and 4 (7%) are department chairs. Resident awardees have a median of 886 citations (interquartile range 237–2,111) and an H-index of 14 (interquartile range 7–23). Seven (13%) went on to receive K08/K23 awards, and 7 (13%) received R01s, with a total of about $200 million in National Institutes of Health funding (79-fold return on investment). Thirty-four junior faculty awardees were included, 10 (29%) of whom were female. Thirteen (38%) are now professors, 12 (35%) are division chiefs, and 7 (21%) are department chairs. Faculty awardees have a median of 2,617 citations (interquartile range 1,343–7,857) and an H-index of 25 (interquartile range 18–49). Four (12%) received K08 or K23 awards, and 10 (29%) received R01s, with about $139 million in National Institutes of Health funding (98-fold return on investment).
Association for Academic Surgery/Society of University Surgeons research awardees experience high degrees of success in academic surgery. Most resident awardees pursue fellowship training and remain in academic surgery. A high percentage of both faculty and resident awardees hold leadership positions and successfully achieve National Institutes of Health funding.
Preparing a grant proposal is no small feat, especially for research (R-series) grants from the National Institutes of Health. The National Institutes of Health is the largest public funder of ...biomedical research in the world, and as such, procuring a research grant from the National Institutes of Health is one of the ultimate benchmarks of success for a surgeon–scientist. Most investigators are familiar with the page limits for most R-series grants (12 pages for an R01 and 6 pages for an R21), with the addition of a single page allotted for the specific aims. Interestingly, despite the usual focus on the aforementioned research section, the rest of the application can routinely consist of an additional 100 to 150 pages, which means that pages allotted for the specific aims and research strategy represent only 10% of the complete application package. For busy surgeons, it is this abundance of ancillary documentation that can make preparing a research grant particularly onerous. Fortunately, for some, support exists within the department to help prepare much of this documentation by drawing from previous sources, templates, and boilerplate language that has been developed. Although these resources can significantly reduce the burden on individual investigators, there is a danger of leaning on generalized templates that can dilute the message of the overall grant proposal and introduce extraneous or incorrect information that can ultimately impact the cohesiveness and ultimately the competitiveness of the grant. The focus of this article is to educate surgeon–scientists regarding the purpose and importance of the ancillary information required for National Institutes of Health research grants and how to make the most of institutional resources while tailoring these materials to create a cohesive, competitive grant application.
•Unexpected high prevalence of mcr-1 in stool specimens of patients attending a tertiary care hospital.•Variable antibioltic-susceptibility profiles of mcr-1 positive Enterobacteriaceae isolates.•No ...detection of mcr-1 positive carbapenem-resistant Enterobacteriaceae.•First report of the prevalence of human faecal carriage of mcr-1 in Singapore.
The aim of this study was to determine the prevalence of the colistin-resistance gene (mcr-1) and the antibiotic-susceptibility profile of mcr-1 positive, colistin-resistant isolates in stool specimens of patients attending a tertiary care hospital in Singapore.
201 diarrheal stool specimens of patients attending the Changi General Hospital between May to August 2017 were collected and screened for the presence of mcr-1 by culture and molecular methods. Antibiotic-susceptibility profile of mcr-1 positive isolates was determined using the polymyxin B and colistin E-tests and the VITEK 2 system.
We observed an unexpectedly high prevalence of mcr-1 in patients attending a tertiary care hospital in Singapore, i.e 6.0% and 8.0% estimated by stool culture and direct stool PCR, respectively. The mcr-1 gene was detected predominantly in Escherichia coli. Antibiotic-susceptibility testing on 12 mcr-1 positive Enterobacteriaceae isolates revealed variable susceptibility profiles with no detection of carbapenem-resistant Enterobacteriaceae.
This is the first report of the prevalence of human faecal carriage of mcr-1 in Singapore. Our findings highlight the potential risk of mcr-1 spread among our patient cohort. The mcr-1 gene detection combined with the detection of other resistance gene targets of clinical importance is recommended to pre-empt the spread mcr-1 in our patients.
Spontaneous intestinal perforations in the neonatal population are mostly associated with low birth weight, prematurity, and necrotizing enterocolitis. Spontaneous intestinal perforation in the ...absence of these risk factors is extremely rare and should raise clinical concern for an underlying bowel pathology. Here we present a unique case of a normal-weight, full-term girl with spontaneous intestinal perforation due to a spindle cell neoplasm with a novel
BRAF
mutation and infantile fibrosarcoma-like morphology. Though rare, malignancy should be considered in the differential diagnosis for bowel perforation in an otherwise healthy, term infant as complete surgical excision can be curative.
This retrospective study was performed to evaluate the frequency of anaerobic bacteraemia over a 10-year period, and to provide updated antibiotic susceptibilities for the more clinically relevant ...anaerobes causing blood stream infection.
Data were retrieved from the laboratory information system for the period 2003 to 2012. During this time, blood cultures were inoculated in Bactec™ Plus vials (BD, USA) and continuously monitored in the Bactec™ 9000 blood culture system (BD, USA). Anaerobic organisms were identified using commercial identification kits, predominantly API 20 A (bioMérieux, France) supplemented with Vitek ANC cards (bioMérieux, France) and AN-Ident discs (Oxoid, United Kingdom). A representative subset of isolates were retrieved from 2009 to 2011 and antimicrobial susceptibilities to penicillin, amoxicillin-clavulanate, clindamycin, imipenem, moxifloxacin, piperacillin-tazobactam and metronidazole were determined using the Etest method.
Anaerobes comprised 4.1% of all positive blood culture with 727 obligate anaerobes recovered over the 10-year period, representing a positivity rate of 0.35%. The only significant change in anaerobe positivity rates occurred between 2003 and 2004, with an increase of 0.2%. The Bacteroides fragilis group (45%) were the predominant anaerobic pathogens, followed by Clostridium species (12%), Propioniobacterium species (11%) and Fusobacterium species (6%). The most active in vitro antibiotics were imipenem, piperacillin-tazobactam, amoxicillin-clavulanate and metronidazole, with susceptibilities of 95.0%, 93.3%, 90.8% and 90.8% respectively. Resistance was high to penicillin, clindamycin and moxifl oxacin. However, there were apparent differences for antibiotic susceptibilities between species.
This study indicates that the anaerobes comprise a small but constant proportion of bloodstream isolates. Antibiotic resistance was high to some antibiotics, but metronidazole, the beta-lactam/beta-lactamase inhibitors and carbapenems retained good in vitro activity.
Fetus-in-fetu (FIF) is a rare congenital anomaly where a parasitic twin is within the body of a host twin. FIF is reported to occur in 1:500,000 live births. Herein, we report the first case of the ...medical and surgical treatment of a FIF patient who was born with extreme prematurity at 25-weeks gestation. With the multi-disciplinary coordination of neonatology, surgery, and interventional radiology, the patient was able to achieve a window of medical stability 4 weeks after birth. A decision was made at that time to proceed with an intra-abdominal and perineal resection of the FIF. The FIF was successfully resected and the patient was able to recover from the operation, with eventual discharge from the NICU. In conclusion, extreme prematurity and FIF may be amenable to surgical resection and a multi-disciplinary approach is crucial to achieve the desired outcome.
Overweight and obese women are known to be at increased risk of caesarean birth. This study estimates the contribution of prepregnancy body mass index (BMI) and gestational weight gain (GWG) to ...caesarean births in Canada.
We analyzed data from women in the Canadian Maternity Experiences Survey who had a singleton term live birth in 2005-2006. Adjusted odds ratios for caesarean birth across BMI and GWG groups were derived, separately for nulliparous women and parous women with and without a prior caesarean. Population attributable fractions of caesarean births associated with above normal BMI and excess GWG were calculated.
The overall caesarean birth rate was 25.7%. Among nulliparous and parous women without a previous caesarean birth, rates in obese women were 45.1% and 9.7% respectively, and rates in women who gained above their recommended GWG were 33.5% and 8.0% respectively. Caesarean birth was more strongly associated with BMI than with GWG. However, due to the high prevalence of excess GWG (48.8%), the proportion of caesareans associated with above normal BMI and excess GWG was similar 10.1% (95% CI: 9.9-10.2) and 10.9% (95% CI: 10.7-11.1) respectively. Overall, one in five (20.2%, 95% CI: 20.0-20.4) caesarean births was associated with above normal BMI or excess GWG.
Overweight and obese BMI and above recommended GWG are significantly associated with caesarean birth in singleton term pregnancies in Canada. Strategies to reduce caesarean births must include measures to prevent overweight and obese BMI prior to conception and promote recommended weight gain throughout pregnancy.
Objective
Prognosis studies examine outcomes and/or seek to identify predictors or factors associated with outcomes. Many prognostic factors have been identified in systemic lupus erythematosus ...(SLE), but few have been consistently found across studies. We hypothesized that this is due to a lack of rigor of study designs. This study aimed to systematically assess the methodologic quality of prognosis studies in SLE.
Methods
A search of prognosis studies in SLE was performed using MEDLINE and Embase, from January 1990 to June 2011. A representative sample of 150 articles was selected using a random number generator and assessed by 2 reviewers. Each study was assessed by a risk of bias tool according to 6 domains: study participation, study attrition, measurement of prognostic factors, measurement of outcomes, measurement/adjustment for confounders, and appropriateness of statistical analysis. Information about missing data was also collected.
Results
A cohort design was used in 71% of studies. High risk of bias was found in 65% of studies for confounders, 57% for study participation, 56% for attrition, 36% for statistical analyses, 20% for prognostic factors, and 18% for outcome. Missing covariate or outcome information was present in half of the studies. Only 6 studies discussed reasons for missing data and 2 imputed missing data.
Conclusion
Lack of rigorous study design, especially in addressing confounding, study participation and attrition, and inadequately handled missing data, has limited the quality of prognosis studies in SLE. Future prognosis studies should be designed with consideration of these factors to improve methodologic rigor.
