Esophageal adenocarcinoma heterogeneity in clinicopathology and prognosis: A single center longitudinal study of 146 cases over a 20-year period.

Recent genomic studies suggest that esophageal adenocarcinoma (EAC) is not homogeneous and can be divided into true (tEAC) and probable (pEAC) groups. We compared clinicopathologic and prognostic features between the two groups of EAC. Based on endoscopic, radiologic, surgical, and pathologic reports, tumors with epicenters beyond 2 cm of the gastroesophageal junction (GEJ) were assigned to the tEAC group (N = 63), while epicenters within 2 cm of, but not crossing the GEJ, were allocated to the pEAC group (N = 83). All 146 consecutive patients were male (age: median 70 years, range: 51-88) and White-predominant (98.6 %). There was no significant difference in gastroesophageal reflux disease, obesity, comorbidity, and the prevalence of Barrett's esophagus, and cases diagnosed during endoscopic surveillance. However, compared to the pEAC group, the tEAC group had significantly more cases with hiatal hernia (P = 0.003); their tumors were significantly smaller in size (P = 0.007), more frequently with tubular/papillary adenocarcinoma (P = 0.001), had fewer cases with poorly cohesive carcinoma (P = 0.018), and demonstrated better prognosis in stage I disease (P = 0.012); 5-year overall survival (34.9 months) was significantly longer (versus 16.8 months in pEACs) (P = 0.043). Compared to the patients without resection, the patients treated with endoscopic or surgical resection showed significantly better outcomes, irrespective of stages. We concluded that EACs were heterogeneous with two distinct tEAC and pEAC groups in clinicopathology and prognosis; resection remained the better option for improved outcomes. CONDENSED ABSTRACT: Esophageal adenocarcinoma can be divided into true or probable groups with distinct clinicopathology and better prognosis in the former than in the latter. we showed that resection remained the better option for improved outcomes.

Geographic differences in therapy for stage I non-small-cell lung cancer in older adults.

BACKGROUND: Geographic and socioeconomic factors impact patient treatment choices for certain cancers. Whether they impact treatment in older adults with lung cancer is unknown. We investigated geographic differences in treatment for stage I non-small-cell lung cancer (NSCLC) in older adults in the United States. METHODS: Using the Surveillance, Epidemiology and End Results Database 18th submission, a cohort of stage I NSCLC patients ≥60-years-old was created. Treatment differences (surgery or radiation alone) by geographic location and socioeconomic factors were analyzed. RESULTS: Forty-three thousand three hundred and eighty-seven stage I NSCLC patients were analyzed. Demographics and socioeconomic factors varied across all 13 states (p < 0.001). Surgery was the most common treatment in all states (range 58.6% in AK to 86.5% in CT) (all p < 0.001). Our multivariable analysis found older individuals had higher odds of getting radiation as compared to surgery (odds ratio [OR]: 1.22 for 65-69 years-old to OR: 8.95 for 85+ years-old; p < 0.001). Multiple states (LA, HI, IA, MI, WA, NM) were associated with increased odds of radiation use (vs. surgery alone) (all p < 0.05). People with lower education level (OR: 0.98) and median income (OR: 0.99) and non-Black race (OR: 0.52 for "other" to OR: 0.68 for "White" race with respect to Black race) were associated with lower odds of radiation (p < 0.05). CONCLUSIONS: Our study identified treatment differences for stage I NSCLC patients in the United States related to demographics, socioeconomic factors, and geographic location.

Measuring Processes of Care in Palliative Surgery: A Novel Approach Using Natural Language Processing.

: Palliative surgical procedures are often performed for patients with limited survival. Quality measures for processes of care at the end of life are appropriate in palliative surgery, but have not been applied in this patient population. In this paper, the authors propose 4 quality measures for end-of-life care in a palliative surgery, and then demonstrate the utility of natural language processing for implementing these measures.

A new diagnosis of Williams-Beuren syndrome in a 49-year-old man with severe bullous emphysema.

Williams-Beuren syndrome (WBS) is a chromosomal microdeletion syndrome typically presenting with intellectual disability, a unique personality, a characteristic facial appearance, and cardiovascular disease. Several clinical features of WBS are thought to be due to haploinsufficiency of elastin (ELN), as the ELN locus is included within the WBS critical region at 7q11.23. Emphysema, a disease attributed to destruction of pulmonary elastic fibers, has been reported in patients without WBS who have pathogenic variants in ELN but only once (in one patient) in WBS. Here we report a second adult WBS patient with emphysema where the diagnosis of WBS was established subsequent to the discovery of severe bullous emphysema. Haploinsufficiency of ELN likely contributed to this pulmonary manifestation of WBS. This case emphasizes the contribution of rare genetic variation in cases of severe emphysema and provides further evidence that emphysema should be considered in patients with WBS who have respiratory symptoms, as it may be under-recognized in this patient population.

Prognostic factors in clinicopathology of oesophagogastric adenocarcinoma: a single-centre longitudinal study of 347 cases over a 20-year period.

Oesophagogastric adenocarcinoma (EGA) includes oesophageal (EA), gastro-oesophageal junctional (GEJA), and gastric (GA) adenocarcinomas. The prognostic values of clinicopathological factors in these tumours remain obscure, especially for GEJA that has been inconsistently classified and staged. We studied the prognosis of EGA patients among the three geographic groups in 347 consecutive patients with a median age of 70 years (range 47-94). All patients were male, and 97.1% were white. Based on tumour epicentre location, EGAs were sub-grouped into EA (over 2 cm above the GEJ; n=3, 18.1%), GEJA (within 2 cm above and 3 cm below the GEJ; n=231, 66.6%), and GA (over 3 cm below the GEJ; n=53, 15.3%). We found that the median overall survival (OS) was the longest in EA (62.9 months), compared to GEJA (33.4), and GA (38.1) (p<0.001). Significant risk factors for OS included tumour location (p=0.018), size (p<0.001), differentiation (p<0.001), adenocarcinoma subtype (p<0.001), and TNM stage (p<0.001). Independent risk factors for OS comprised low-grade papillary adenocarcinoma [odds ratio (OR) 0.449, 95% confidence interval (CI) 0.214-0.944, p<0.05), mixed adenocarcinoma (OR 1.531, 95% CI 1.056-2.218, p<0.05), adenosquamous carcinoma (OR 2.206, 95% CI 1.087-4.475, p<0.05), N stage (OR 1.505, 95% CI 1.043-2.171, p<0.05), and M stage (OR 10.036, 95% CI 2.519-39.993, p=0.001)]. EGA was further divided into low-risk (common well-moderately differentiated tubular and low-grade papillary adenocarcinomas) and high-risk (uncommon adenocarcinoma subtypes, adenosquamous carcinoma) subgroups. In this grouping, the median OS was significantly longer in the low-risk (83 months) than in the high-risk (10 months) subgroups (p<0.001). In conclusion, the prognosis of EGA patients was significantly better in EA than in GEJA or GA and could be stratified into low and high-risk subgroups with significantly different outcomes.

Risks of Transthoracic Needle Biopsy: How High?

Transthoracic needle lung biopsy is a commonly performed diagnostic procedure for pulmonary nodules and masses. To make an informed decision about whether to pursue this procedure, doctors and patients must be aware of the possible risks of the procedure. We performed a MEDLINE search, 2003-2012 to identify relevant English-language studies that included at least 100 subjects and reported data on complications of transthoracic needle lung biopsy performed within the last 10 years. We found the most common complication to be any pneumothorax (risk 15-25%), with pneumothorax requiring chest tube occurring less often (risk 4-6%). Hemorrhage, defined as radiographically visualized blood along the needle tract was common, but clinically significant hemorrhage was infrequent (~1%). Rare complications, including air embolism and tumor seeding of the biopsy tract, occurred in fewer than 1% of cases but were potentially serious. We summarize data on factors associated with complications, including patient age, COPD, lesion size and location, and number of punctures. We also provide data on techniques to mitigate severity of pneumothorax post-biopsy, such as rapid patient rollover, manual aspiration, and instillation of substances into the biopsy tract.

Patients with esophageal adenocarcinoma showed better prognosis than those with adenocarcinoma of the gastroesophageal junction.

OBJECTIVES: We followed The Cancer Genome Atlas (TCGA) grouping criteria and conducted a clinicopathological cohort study in a unique patient population to gain insight into the pathobiology of esophageal adenocarcinoma (EAC) and adenocarcinoma of the gastroesophageal junction (AGEJ). METHODS: We studied and statistically compared the clinicopathological and prognostic features of both cancers in 303 consecutive patients treated at the Veterans Affairs Boston Healthcare System over a 20-year period using uniform criteria and standardized routines. RESULTS: Over 99% of patients were white men with a mean age of 69.1 years and an average body mass index (BMI) of 28.0 kg/m2 . No significant differences were detected in age, gender, ethnicity, BMI, and history of tobacco abuse between the two groups. Compared to AGEJ patients, a significantly higher proportion of EAC patients had gastroesophageal reflux disease, long-segment Barrett's esophagus, common adenocarcinoma type, smaller tumor size, better differentiation, more stages I or II but fewer stages III or IV diseases, scarcer lymph node invasion, fewer distant metastases, and better overall, disease-free, and relapse-free survival. The 5-year overall survival rate was significantly higher in EAC patients than in AGEJ patients (41.3% vs 17.2%, P < 0.001). This improved survival among EAC patients remained significant after censoring all cases detected during endoscopic surveillance, suggesting different pathogenesis mechanisms between EAC and AGEJ. CONCLUSIONS: EAC patients showed significantly better outcomes than AGEJ patients. Our results require validation in other patient populations.

Endoluminal Vacuum Therapy for Definitive Management of an Esophagobronchial Fistula.

PURPOSE: Endoluminal vacuum (EVAC) therapy has gained popularity as a minimally invasive option for contained esophageal leaks. EVAC therapy may be useful for esophagogastric anastomotic leak fistulizing to the airway. DESCRIPTION: This report describes EVAC therapy of an esophagobronchial fistula with video depicting the procedure, including technical tips. Video and photographic evidence of progression and ultimate resolution is included. EVALUATION: Sponge exchanges were completed every 3 to 4 days. EVAC therapy was administered through a transnasal approach. In the presented case, a total of 11 exchanges over 6 weeks were required. EVAC sponge placement was transitioned from intracavitary to endoluminal for the final 4 treatments. All but 4 exchanges were able to be completed at the bedside in a monitored setting with sedation. CONCLUSIONS: An esophageal leak that has fistulized to a main airway is a rare and challenging clinical problem. Definitive EVAC therapy for esophageal anastomotic leak with esophagobronchial fistula is a feasible option in selected cases.

Bronchopleural fistula due to cavitary pneumonia after SARS-CoV-2 infection treated with open thoracostomy.

Severe coronavirus disease of 2019 (COVID-19) disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes substantial parenchymal damage in some patients. There is a paucity of literature describing the surgical management COVID-19 associated bronchopleural fistula after failure of medical therapy. We present the case of a 59-year-old woman with SARS-CoV-2 pneumonia, secondary bacterial pneumonia with bronchopleural fistula and radiographic and clinical evidence of disease refractory to medical therapy. After a course of culture-driven antimicrobial therapy and failure to improve following drainage with tube thoracostomy, she was treated successfully with Clagett open thoracostomy. After resolution of the bronchopleural fistula, the thoracostomy was closed and she was discharged home. In cases of severe COVID-19 complicated by bronchopleural fistula with parenchymal destruction, a tailored approach involving surgical management when indicated can lead to acceptable outcomes without significant morbidity.

Internal Staging Discordance in National Cancer Databases for Non-Small Cell Lung Cancer.

BACKGROUND: The Surveillance, Epidemiology and End Results (SEER) and the National Cancer Database (NCDB) are databases for cancer analysis that may be subject to error in data reporting. This study examined the rates and impact of discordant data for non-small cell lung cancer. METHODS: NCDB and SEER were queried for non-small cell lung cancer pathologic tumor, node, metastasis data (NCDB) or "derived" data (SEER). Discordancy between descriptors with stage and impact of outlier data were analyzed. RESULTS: Incomplete staging was noted in 71.5% of the NCDB and 10.3% of SEER patients. A total of 174 829 patients from the NCDB and 117 114 from SEER were analyzed. The NCDB had 97 cases with ≥20 positive lymph nodes recorded vs 27 in SEER (P < .001). Mean and median sampled lymph nodes were skewed with inclusion of these data points (P < .001). The NCDB misclassified 0.99% tumors >5 cm as stage I vs 0.04% in SEER (P < .001). The NCDB misstaged positive lymph nodes as pathologic N0 (0.59%) or stage 0 or stage I (0.65%). The NCDB misclassified pathologic N1 as lower than stage II (0.91%) or N2 as lower than stage III (0.36%). The NCDB misclassified stage I with documentation of pathologic N1 or N3 disease (0.24%) or stage II with evidence of N2 or N3 disease (0.50%). The NCDB misclassified pathologic M1 as pathologic stage

Mandatory Nodal Evaluation During Resection of Clinical T1a Non-Small Cell Lung Cancers.

BACKGROUND: Recommendations for intraoperative lymph node evaluation are uniform regardless of whether a primary tumor is clinical T1a or T2a according to TNM 8th edition for stage I non-small cell lung cancer (NSCLC). We quantified nodal disease risk in patients with T1a disease (≤1 cm). METHODS: The National Cancer Database was queried for clinical T1a N0 M0 primary NSCLCs ≤1 cm undergoing lobectomy with mediastinal nodal evaluation from 2004-2014. Nodal disease risk was analyzed as a function of demographics and tumor characteristics. RESULTS: Among 2157 cases, 6.7% had occult nodal disease: 5.1% occult N1 and 1.6% N2. Adenocarcinoma (7.5%), large cell carcinoma (25%), and poor differentiation (11.8%) or undifferentiated/anaplastic (25.0%) had high rates of combined pN1 and N2 disease (P < .001). In univariable analysis, odds of pathologic N1, N2, or N1/N2 nodal disease with respect to N0 was greatest for large cell carcinoma (ref. adenocarcinoma odds ratio [OR] 4.31, 3.62, 4.12 respectively; all P < .05), and anaplastic grade (OR 10.71, 13.09, 11.55). Bronchoalveolar adenocarcinomas had the lowest odds (OR 0.41, 0.11, 0.32) and squamous cell carcinoma had lower odds for N2 (OR 0.29, all P < .05). In multivariable analysis only bronchoalveolar adenocarcinomas had lower odds of pathologic N2 and N1/N2 disease with respect to N0. Worsening grade remained significant for pathologic N1 and N1/N2 disease (both P < .05). CONCLUSIONS: A significant rate (6.7%) of occult nodal disease is present in primary NSCLCs ≤1 cm. Risk increases with certain histology and worsening grade. We recommend mandatory systematic hilar and mediastinal nodal evaluation for T1a NSCLC tumors for accurate staging and adjuvant therapy.

Esophagectomy for Esophageal Cancer Performed During the Early Phase of the COVID-19 Pandemic.

Delay in time to esophagectomy for esophageal cancer has been shown to have worse peri-operative and long-term outcomes. We hypothesized that COVID-19 would cause a delay to surgery, with worse perioperative outcomes, compared to standard operations. All esophagectomies for esophageal cancer at a single institution from March-June 2020, COVID-19 group, and from 2019 were reviewed and peri-operative details were compared between groups. Ninety-six esophagectomies were performed in 2019 vs 37 during March-June 2020 (COVID-19 group). No differences between groups were found for preoperative comorbidities. Wait-time to surgery from final neoadjuvant treatment was similar, median 50 days in 2019 vs 53 days during COVID-19 p = 0.601. There was no increased upstaging, from clinical stage to pathologic stage, 9.4% in 2019 vs 7.5% in COVID-19 p = 0.841. Fewer overall complications occurred during COVID-19 vs 2019, 43.2% vs 64.6% p = 0.031, but complications were similar by specific grades. Readmission rates were not statistically different during COVID-19 than 2019, 16.2% vs 10.4% p = 0.38. No peri-operative mortalities or COVID-19 infections were seen in the COVID-19 group. Esophagectomy for esophageal cancer was not associated with worse outcomes during the COVID-19 pandemic with minimal risk of infection when careful COVID-19 guidelines are followed. Prioritization is recommended to ensure no delays to surgery.

Report on lung cancer surgery during COVID-19 pandemic at a high volume US institution.

Background: The impact of COVID-19 has been felt in every field of medicine. We sought to understand how lung cancer surgery was affected at a high volume institution. We hypothesized that patients would wait longer for surgery, have more advanced tumors, and experience more complications during the COVID-19 crisis. Methods: A retrospective review was conducted, comparing pathologically confirmed non-small cell lung cancer (NSCLC) surgical cases performed in 2019 to cases performed from March to May 2020, during the height of the COVID-19 crisis. Clinical and pathologic stage, tumor size, time to surgery, follow up time, and complications were evaluated. Results: A total of 375 cases were performed in 2019 vs. 58 cases in March to May 2020. Overall, there were no differences in the distribution of clinical stages or in the distribution of median wait times to surgery between groups (COVID-19 16.5 days vs. pre-COVID-19 17 days, P=0.54), nor were there differences when subdivided into Stage I-II and Stage III-IV. Case volume was lowest in April 2020 with 6 cases vs. 37 in April 2019, P<0.01. Tumor size was clinically larger in the COVID-19 group (median 2.1 vs. 1.9 cm, P=0.05) but not at final pathology. No differences in complications were observed between groups (COVID-19 31.0% vs. pre-COVID-19 30.9%, P=1.00). No patients from the COVID-19 group tested positive for the disease during their hospital stay or by the median 15 days to first follow-up. Conclusions: Surgical wait time, pathologic tumor size, and complications were not different among patients undergoing surgery before vs. during the pandemic. Importantly, no patients became infected as a result of their hospital stay. The significant decrease in surgical cases is concerning for untreated cancers that may progress without proper treatment.

Controlled apneic tracheostomy in patients with coronavirus disease 2019 (COVID-19).

OBJECTIVE: To develop a team-based institutional infrastructure for navigating management of a novel disease, to determine a safe and effective approach for performing tracheostomies in patients with COVID-19 respiratory failure, and to review outcomes of patients and health care personnel following implementation of this approach. METHODS: An interdisciplinary Task Force was constructed to develop innovative strategies for management of a novel disease. A single-institution, prospective, nonrandomized cohort study was then conducted on patients with coronavirus disease 2019 (COVID-19) respiratory failure who underwent tracheostomy using an induced bedside apneic technique at a tertiary care academic institution between April 27, 2020, and June 30, 2020. RESULTS: In total, 28 patients underwent tracheostomy with induced apnea. The median lowest procedural oxygen saturation was 95%. The median number of ventilated days following tracheostomy was 11. There were 3 mortalities (11%) due to sepsis and multiorgan failure; of 25 surviving patients, 100% were successfully discharged from the hospital and 76% are decannulated, with a median time of 26 days from tracheostomy to decannulation (range 12-57). There was no symptomatic disease transmission to health care personnel on the COVID-19 Tracheostomy Team. CONCLUSIONS: Patients with respiratory failure from COVID-19 disease may benefit from tracheostomy. This can be completed effectively and safely without viral transmission to health care personnel. Performing tracheostomies earlier in the course of disease may expedite patient recovery and improve intensive care unit resource use. The creation of a collaborative Task Force is an effective strategic approach for management of novel disease.

Analysis of Lymph Node Sampling Minimums in Early Stage Non-Small-Cell Lung Cancer.

Analyze "number of nodes" as an integer-valued variable to identify possible minimum lymph node (LN) number to sample during lung cancer resection. The National Cancer Database (NCDB) queried 2004-14 for surgically treated clinical stage I/II non-small-cell lung cancer (NSCLC). Overall survival (OS) by number of LN sampled was examined for the complete dataset, by adenocarcinoma, and by degree of resection using number of sampled LN both as integer-valued (0-30 nodes) variable and collapsed into classes. A total of 102,225 patients were analyzed. Median sampled LNs were 7. Median overall survival was 59 months if no LNs were sampled (95% confidence interval [CI]: 57.0-62.4), 74.7 months for 1 sampled LN (95% CI: 69.6-78.1), 80.2 (95% CI: 74.2-85.6) for 2 sampled LN, up to 81.5 mos. for 29 sampled LN. A Cox regression model using "0 LN" as baseline level, showed association with increased overall survival starting at 1 LN (hazard ratio [HR] 0.81, 95% CI 0.76-0.87; P <0.001). A "moving baseline" Cox regression model, showed no additional benefit when sampling additional nodes. We noticed a decreasing, linear association between OS and a number of 0-5 sampled LNs, most pronounced between 0 and 1 LN sampled, using a martingale residual plot from a null Cox model; no association was observed for more sampled LNs. For patients undergoing lobectomy, difference in OS was noted between 0 and 1LN sampled but not between 2 and 30 LN. These differences were not statistically significant until the number of 4 removed LN (respectively 3 for wedge-resections). For segmentectomies, median survival was not statistically associated with number of LN sampled. Based on NCDB data, LN sampling for lung cancer resections is recommended. Lobectomy survival is positively associated with 4 LN sampled, but ideal sampling may lie at 5LN in most cases. NCDB data does not seem to justify the quality metric of minimum 10 LNs.

Impact of radial margins after esophagectomy for esophageal cancer.

INTRODUCTION: The prognostic significance of radial margin (RM) involvement in esophagectomy cancer specimens is unclear. Our study investigated survival and recurrence rates between different depths of RM involvement. MATERIALS AND METHODS: We retrospectively analyzed 1103 esophagectomies at our institution from 2005 to 2019. Patients were grouped by three-tier stratification: negative RM > 1 mm away, direct RM involvement at 0 mm, and close RM between 0 mm and 1 mm. Survival, loco-regional and distant recurrences were analyzed. RESULTS: 1103 esophageal cancer patients were analyzed. 389 patients had recurrence (35.3%). Median survival (13.2 months) and recurrence rates (71%) were worst with direct RM (p < 0.001) as compared to negative RM (median survival not achieved within 5-years from surgery and 30%). Without nodal involvement, RM involvement of <1 mm was associated with decreased overall survival, and overall, loco-regional and distant recurrence-free survival compared to negative RM (log rank p-value <0.05). In those with persistent nodal disease, only direct RM was associated with decreased overall and loco-regional recurrence-free survival as compared to negative margins (p < 0.05). Direct RM tended to do worse compared to close RM in terms of median survival and trended worse for recurrence. Direct RM (baseline negative RM), but not close RM, was an independent RF in a multivariable Cox model for worse overall survival (HR 2.74; p < 0.001), recurrence-free survival (HR 1.96; p = 0.019), and loco-regional recurrence-free survival (HR 3.19; p = 0.011). CONCLUSION: RM involvement affects survival and recurrence. Tumor at 0 mm remained an independent RF for worse survival and overall and loco-regional recurrence.

Treatment of ultralong-segment Barrett's using focal and balloon-based radiofrequency ablation.

INTRODUCTION: Endoscopic radiofrequency ablation (ERFA) is being evaluated as definitive treatment for patients with Barrett's esophagus (BE). Guidelines have yet to be developed for the application of this technology to patients with ultralong-segment BE (ULBE, > or = 8 cm). This study reports a single institution's experience with ERFA of ULBE. METHODS: A retrospective review of patients with ULBE undergoing ERFA from August 2005 to February 2009 was conducted. The entire segment of intestinal metaplasia (IM) was treated at each session using balloon- and/or plate-based devices (BARRX Medical, Inc., Sunnyvale, CA). Retreatments, endoscopic mucosal resection (EMR), dilations, and biopsies were performed based on endoscopic findings. Surveillance was conducted according to standard guidelines. RESULTS: Twenty-five patients (22 male) with a median age of 66 years [interquartile range (IQR) 57-74 years] were included. The length of BE treated was 10 cm (median; IQR 8-12 cm). Intramucosal carcinoma (IMC) was present in 3 patients, 15 had high-grade dysplasia (HGD), 6 had low-grade dysplasia (LGD), and 1 had IM without dysplasia. Complications for all 25 patients included hemorrhage (n = 1), stricture (n = 2), and nausea and vomiting (n = 2). Time from the initial procedure was such that 15 patients had postablation biopsies at least once. One patient with biopsies elected to undergo esophagectomy. Of these patients, 78.5% (11/14) had complete response (CR; no residual IM), two patients regressed from HGD to IM, and one patient with IMC had residual HGD and was treated with repeat EMR. The number of ablations in this group was 2.5 (median, IQR 2-3) during a median follow-up time of 20.3 months (IQR 10.4-29.2 months). CONCLUSION: ERFA is safe and feasible in patients with ULBE and can be applied to the entire length of IM during one session. Eradication of BE can be achieved with few repeat ablations and continued, vigilant surveillance.

Patient-Centered, Guideline-Concordant Discussion and Management of Pulmonary Nodules.

Providing guideline-concordant management of pulmonary nodules can present challenges when a patient's anxiety about cancer or fear of invasive procedures colors judgment. The way in which providers discuss and make decisions about how to evaluate a pulmonary nodule can affect patient satisfaction, distress, and adherence to evaluation. This article discusses the complexity of tailoring patient-provider communication, decision-making, and implementation of guidelines for pulmonary nodule evaluation to the individual patient, emphasizing the importance of how information is conveyed and the value of listening to and addressing patients' concerns. We summarize the relevant guideline recommendations and literature, and provide two case scenarios to illustrate a patient-centered approach to discussing and managing pulmonary nodules from our perspectives as a pulmonologist and thoracic surgeon.

Intestinal Tamponade.

Concurrence of a congenital Morgagni hernia and paraesophageal hernia is rare and can occasionally present as a medical emergency. Here, we report a unique case of a patient with paroxysms of cough-induced syncope secondary to cardiac compression by a simultaneously occurring anterior Morgagni hernia and posterior paraesophageal hernia.

Benefits and risks of tight glucose control in critically ill adults: a meta-analysis.

CONTEXT: The American Diabetes Association and Surviving Sepsis Campaign recommend tight glucose control in critically ill patients based largely on 1 trial that shows decreased mortality in a surgical intensive care unit. Because similar studies report conflicting results and tight glucose control can cause dangerous hypoglycemia, the data underlying this recommendation should be critically evaluated. OBJECTIVE: To evaluate benefits and risks of tight glucose control vs usual care in critically ill adult patients. DATA SOURCES: MEDLINE (1950-2008), the Cochrane Library, clinical trial registries, reference lists, and abstracts from conferences from both the American Thoracic Society (2001-2008) and the Society of Critical Care Medicine (2004-2008). STUDY SELECTION: We searched for studies in any language in which adult intensive care patients were randomly assigned to tight vs usual glucose control. Of 1358 identified studies, 34 randomized trials (23 full publications, 9 abstracts, 2 unpublished studies) met inclusion criteria. DATA EXTRACTION AND ANALYSIS: Two reviewers independently extracted information using a prespecified protocol and evaluated methodological quality with a standardized scale. Study investigators were contacted for missing details. We used both random- and fixed-effects models to estimate relative risks (RRs). RESULTS: Twenty-nine randomized controlled trials totaling 8432 patients contributed data for this meta-analysis. Hospital mortality did not differ between tight glucose control and usual care overall (21.6% vs 23.3%; RR, 0.93; 95% confidence interval [CI], 0.85-1.03). There was also no significant difference in mortality when stratified by glucose goal ([1] very tight: < or = 110 mg/dL; 23% vs 25.2%; RR, 0.90; 95% CI, 0.77-1.04; or [2] moderately tight: < 150 mg/dL; 17.3% vs 18.0%; RR, 0.99; 95% CI, 0.83-1.18) or intensive care unit setting ([1] surgical: 8.8% vs 10.8%; RR, 0.88; 95% CI, 0.63-1.22; [2] medical: 26.9% vs 29.7%; RR, 0.92; 95% CI, 0.82-1.04; or [3] medical-surgical: 26.1% vs 27.0%; RR, 0.95; 95% CI, 0.80-1.13). Tight glucose control was not associated with significantly decreased risk for new need for dialysis (11.2% vs 12.1%; RR, 0.96; 95% CI, 0.76-1.20), but was associated with significantly decreased risk of septicemia (10.9% vs 13.4%; RR, 0.76; 95% CI, 0.59-0.97), and significantly increased risk of hypoglycemia (glucose < or= 40 mg/dL; 13.7% vs 2.5%; RR, 5.13; 95% CI, 4.09-6.43). CONCLUSION: In critically ill adult patients, tight glucose control is not associated with significantly reduced hospital mortality but is associated with an increased risk of hypoglycemia.
