CONTEXT

Data on the risk of postthyroidectomy complications in elderly patients are sparse, unclear, and conflicting.

OBJECTIVE

We sought to use a population-based cohort to determine whether thyroid operations in the elderly are as safe as those done in younger patients.

DESIGN

This was a prospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2008, with 30-d postoperative follow-up.

SETTING

The American College of Surgeons National Surgical Quality Improvement Program data set contains operative cases from a nationwide sampling of academic and community-based as well as high-volume and low-volume hospitals.

PATIENTS

All thyroidectomy and parathyroidectomy patients reported to the database during the study period were included in the analysis resulting in an experimental cohort of 7915 thyroidectomy cases and a control cohort of 3575 parathyroidectomy cases.

MAIN OUTCOME MEASURES

We aggregated 83 complications into the following outcome measures: urinary tract infection, wound infection, systemic infection, cardiac complications, pulmonary complications, 30-d mortality, and total hospital length of stay.

RESULTS

Increased age is a risk factor for significant pulmonary, cardiac, and infectious complications after thyroidectomy. Elderly patients are twice as likely (odds ratio 2.1, 95% confidence interval 1.4-3.3), and the superelderly are 5 times as likely (odds ratio 4.9, 95% confidence interval 2.5-9.6) to have a complication compared with their young counterparts. Preexisting comorbidities are effect modifiers and increase the risk of complications even further.

CONCLUSIONS

Elderly thyroidectomy patients are at increased risk for major systemic complications. A systematic approach to the care of elderly thyroidectomy patients is necessary to minimize their risk of serious postoperative complications.

BACKGROUND

Data on the characteristics and outcomes of patients operated on by surgical residents are limited.

METHODS

Using ACS-NSQIP (2005-2008), characteristics and outcomes of patients who underwent cholecystectomy, appendectomy, or inguinal hernia repair by a resident (R) without an attending scrubbed in the operating room, a scrubbed attending with resident (AR), or an attending without resident (A) were pooled and compared. Data analyses involved χ(2), ANOVA, and multivariate regression.

RESULTS

The R group performed 1% of ACS-NSQIP cases; the 10 most common procedures represented 69.1% of cases. There were 912 cases of cholecystectomy, appendectomy, or inguinal hernia repair performed by R. Compared with A/AR patients, R patients were more likely to have inpatient (42.6%, 48.9% versus 64.8%), emergent (28.6%, 30.8% versus 35.5%) , and open procedures (27.0%, 29.4% versus 28.9%) (all P 0.001). In unadjusted analyses, R patients had higher complication rates (4.8% versus 4.4%, 3.4%, P 0.001) and longer operating time (64.4 min versus 62.2 min, 44.7 min, P 0.001) than AR/A patients respectively. After risk adjustment, a resident operating without an attending scrubbed in the operating room was not independently associated with increased complications risk (odds ratio 1.2, 95% CI: 0.8-1.8, P = 0.2). Compared with A/AR patients, there was a 1-min difference in adjusted operating time for patients who underwent surgery by R (P 0.001).

CONCLUSIONS

In ACS-NSQIP, a resident rarely performs surgery without an attending scrubbed in the operating room; surgical attendings appear to exercise good judgment in determining the appropriate extent of resident supervision in the operating room without compromising patient outcomes.

Every pregnant woman in the United States is exposed to many and varied environmental chemicals. Rapidly accumulating scientific evidence documents that widespread exposure to environmental chemicals at levels that are encountered in daily life can impact reproductive and developmental health adversely. Preconception and prenatal exposure to environmental chemicals are of particular importance because they may have a profound and lasting impact on health across the life course. Thus, prevention of developmental exposures to environmental chemicals would benefit greatly from the active participation of reproductive health professionals in clinical and policy arenas.

As a result of the accident at the Chernobyl Nuclear Power Plant, millions of residents of Belarus, Russia, and Ukraine were exposed to large doses of radioactive iodine isotopes, mainly I-131. The purpose of the Ukraine-American (UkrAm) and Belarus-American (BelAm) projects are to quantify the risks of thyroid cancer in the framework of a classical cohort study, comprising subjects who were aged under 18 years at the time of the accident, had direct measurements of thyroid I-131 radioactivity taken within two months after the accident, and were residents of three heavily contaminated northern regions of Ukraine (Zhitomir, Kiev, and Chernigov regions). Four two-year screening examination cycles were implemented from 1998 until 2007 to study the risks associated with thyroid cancer due to the iodine exposure caused during the Chernobyl accident. A standardised procedure of clinical examinations included: thyroid palpation, ultrasound examination, blood collection followed by a determination of thyroid hormone levels, urinary iodine content test, and fine-needle aspiration if required. Among the 110 cases of thyroid cancer diagnosed in UkrAm as the result of four screening examinations, 104 cases (94.5%) of papillary carcinomas, five cases (4.6%) of follicular carcinomas, and one case (0.9%) of medullary carcinoma were diagnosed.

BACKGROUND

Tandem colonoscopy is regarded as the reference standard for the evaluation of the adenoma detection rate (ADR) and adenoma miss rate (AMR) during colonoscopy. Pooled results from previous tandem studies yield AMRs of 22%. The AMR of trainees is important to estimate the number of colonoscopies required to develop competence in screening for colorectal neoplasms.

OBJECTIVE

To measure the ADR and AMR of trainees as a function of experience.

METHODS

Prospective tandem colonoscopy study at an academic VA medical center. A trainee initially attempted colonoscopy. If the trainee was able to intubate the cecum, the trainee performed the withdrawal, and the colonoscopy was then repeated by the attending physician to assess the AMR.

RESULTS

Twelve trainee endoscopists were included in the study. Trainees had between 0 and 33 months of previous endoscopic experience and had done between 0 and 605 previous colonoscopies. A total of 230 patients were evaluated for the study, and 218 patients were enrolled. Complete tandem colonoscopy was performed in 147 patients. There was a 54% ADR. The mean (standard deviation) size of the adenomas in the cohort was 5.9 (5.3) mm. Significant variables in multivariate logistic regression analysis for missed adenomas were trainee experience (P = .011) and patient age (P .001). The AMR decreased with increasing experience, and it is estimated that 450 colonoscopies are required to attain AMRs of less than 25% in a 60-year-old patient.

LIMITATIONS

Single-center study; the attending physician performing the second pass was not blinded to the first pass. The AMR was only analyzed for cases in which the trainee was able to reach the cecum with no or minimal assistance.

CONCLUSIONS

Our tandem colonoscopy study demonstrates that the AMR decreases as the experience of trainees increases and is a late competency attained during training. Future training may need to incorporate these findings to serve as a basis for determining appropriate training guidelines.

Papillary thyroid cancer (PTC) has an excellent prognosis, yet lymph node metastases are common. Most authors agree that central and/or lateral lymph node dissection should be undertaken in patients with abnormal lymph nodes detected on ultrasound, physical examination or intraoperative inspection. However the appropriate extent of prophylactic lymph node dissection for clinically node-negative patients remains the subject of controversy. There have been no randomized trials to date to offer guidance on this issue. The 2006 guidelines of the American Thyroid Association recommended consideration of prophylactic bilateral central lymph node dissection (CLND) for all patients undergoing thyroidectomy for PTC. However, the absence of compelling evidence for a benefit in terms of recurrence or survival, and the potential for increased morbidity, have led many, including our institution, to take an approach of selective central lymph node dissection. This approach is guided by the detection of abnormal lymph nodes on preoperative ultrasound, on physical examination, or during surgery. Postoperatively, ultrasound by an experienced ultrasonographer is the mainstay of evaluation for lymph node recurrence and is combined with monitoring of thyroglobulin and antithyroglobulin antibody levels. Reoperative lymph node dissection is typically undertaken upon detection and fine needle aspiration (FNA) of involved lymph nodes 0.8 cm or greater in size.

INTRODUCTION

There has been scant attention to predictors of sexual dysfunction in women who have sex with women (WSW).

AIM

To investigate the associations of high risk for sexual dysfunction in an Internet cohort of WSW.

MAIN OUTCOME MEASURE

A modified version of the Female Sexual Function Index (FSFI) was used to quantify each subject's sexual function.

METHODS

Women who have sex with women were invited to participate in an Internet-based survey by invitations posted on e-mail listservs and on social media sites catering to WSW. Ethnodemographic, health status, and sexual/relationship data were collected.

RESULTS

The study was completed by 2,433 adult women. Of these, 1,566 participants had complete data on the FSFI and comprised the study cohort; 388 (24.8%) met the FSFI criteria for high risk of female sexual dysfunction (HRFSD). On multivariable analysis, the following variables were found to be independently associated with the HRFSD; moderate or severe subjective bother regarding sexual function (OR 4.8, 95% CI 3.0-7.9 and 13.7, 95% CI 7.5-25.1, respectively), overactive bladder (OAB) (OR 2.1, 95% CI 1.0-4.5), having a nonfemale or no partner (OR 2.3, 95% CI 1.1-4.7 and 3.2, 95% CI 2.0-5.2, respectively). A history of pregnancy was associated with lower odds of HRFSD (OR 0.567, 95% CI 0.37-0.87). Mean FSFI domain scores for all domains except desire were negatively impacted by partner factors and OAB.

CONCLUSIONS

A single-item question on sexual bother is strongly predictive of potentially distressing sexual problems in the WSW. A number of health and social factors are associated with risk of sexual problems in the WSW. Assessment of sexual well-being in the WSW is a priority for practicing healthcare providers.
