RESUMEN
BACKGROUND: In this systematic review, the authors discuss traditional management strategies of neuromas. Surgical management can be described as either passive and ablative or active and reconstructive. Our aim was to evaluate the evidence supporting traditional management strategies in patients affected by neuromas. METHODS: The systematic literature search was conducted in PubMed/MEDLINE databases using search terms related to neuromas and their surgical management. Studies involving targeted muscle reinnervation or regenerative peripheral nerve interface were excluded. Two reviewers selected the studies, evaluated their methodological quality, and retrieved data independently. This review was conducted in a manner consistent with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Selected studies were analyzed for pain and functional outcomes. RESULTS: A total of 1064 articles were identified, and 22 studies were selected for review. Passive or ablative modalities for treatment of neuromata include excision of neuroma, excision with implantation into adjacent tissue, nerve caps, vein cap, and relocation nerve grafting. Active or reconstructive modalities that allow for nerve regeneration include hollow tube reconstruction, reconstruction with an allograft, and centrocentral nerve anastomosis. CONCLUSIONS: Passive treatment modalities can offer reliable pain relief in appropriately selected patients but do not allow for nerve regeneration. As such active, reconstructive modalities should be used when possible.

BACKGROUND: Patients suffering from arthritis have limited treatment options for nonoperative management. In search of pain relief, patients have been taking over-the-counter cannabinoids. Cannabidiol (CBD) and cannabichromene (CBC) are minor cannabinoids with reported analgesic and anti-inflammatory properties and have been implicated as potential therapeutics for arthritis-related pain. To this end, we utilized a murine model to investigate the effectiveness of and mechanism by which CBC alone, CBD alone, or CBD and CBC in combination may provide a reduction in arthritis-associated inflammation. METHODS: Forty-eight mice were included in the study, which were separated into 4 groups: control group (n = 12), treatment with CBD alone (n = 12), treatment with CBC alone (n = 12), and treatment with CBD + CBC (n = 12). We induced inflammation in each mouse utilizing the collagen-induced arthritis model. At scheduled timepoints, mice were clinically assessed for weight gain, swelling, and arthritis severity. In addition, inflammation-associated serum cytokine levels were analyzed for each animal. RESULTS: Thirty-five of 48 mice survived the duration of the study resulting in the following group numbers: control group (n = 8), treatment with CBD alone (n = 9), treatment with CBC alone (n = 9), and treatment with CBD + CBC (n = 9). Animals treated with CBC and CBD + CBC showed significant weight gain between 3 and 5 weeks. Irrespective of treatment, regression analysis comparing all cytokine measurement and physical outcomes found a significant positive correlation between levels of 5 individual cytokines and both arthritis scores and swelling. Animals treated with CBD + CBC showed a significant decrease in swelling between 3 and 5 weeks compared with the control group. Cannabinoid treatment selectively affected the gene expression of eotaxin and lipopolysaccharide-induced CXC chemokine with combined treatment of CBC + CBD. CONCLUSION: Treatment with cannabinoids resulted in decreased clinical markers of inflammation. Further, the anti-inflammatory effect of CBC and CBD in conjunction was associated with a greater anti-inflammatory effect than either minor cannabinoid alone. Future work will elucidate the possibility of synergistic or entourage effects of minor cannabinoids used in combination for the treatment of arthritis-related pain and inflammation.

BACKGROUND: Sensation after autologous breast reconstruction is an increasingly important outcome. Several studies demonstrated improved sensation with flap neurotization but utilized heterogenous measures and follow-up intervals. This review evaluates sensory outcomes after neurotization using uniform, objective outcome measurements. METHODS: PubMed/Medline and Embase databases were queried for articles published between January 1990 and January 2022. Inclusion criteria included studies with free flap tissue transfer breast reconstruction patients and use of Semmes-Weinstein Monofilaments (SWM) to quantify return of sensation after either neurotization or no neurotization. Reviews, case reports, and studies utilizing implants or pedicled flaps were excluded. RESULTS: Overall, 513 articles were screened. Eleven articles met inclusion criteria for a total of 474 patients. There were 254 non-neurotized patients included as controls (Group A) and 220 neurotized patients (Group B). Mean follow-up time was similar in both groups (22.06 months vs. 22.78 months, p > 0.05). There was no significant difference in age (Group A = 49.97 years vs. Group B = 42.47 years) or BMI (Group A = 25.48 vs. Group B = 25.97) between groups. More patients in group B received radiation therapy (Group B = 32.72% vs. Group A = 20.86%, p > 0.05). Patients that received neurotization had lower mean pressure thresholds (Group A = 38.85 gm/mm2 vs. Group B = 6.69 gm/mm2 , p = 0.053) than comorbidity-matched controls. CONCLUSION: Neurotization has been shown to be a safe and feasible option for enhancing return of sensation after breast reconstruction. Future studies with standardized, long-term follow-up will further elucidate the pattern of breast sensation return and the impact of neurotization.

OBJECTIVE: We evaluated the outcomes and complications of transcarotid artery revascularization (TCAR) outside of academic vascular surgery programs. METHODS: An institutional review board-approved retrospective study was performed. Data from all cases of TCAR performed at a community hospital from May 2017 to February 2020 were collected and analyzed. Seven vascular surgeons performed the procedures after receiving appropriate training. The primary outcomes included technical success, the need for further revascularization, and major adverse events (death, cerebrovascular accident [CVA], myocardial infarction). The secondary outcomes included other adverse events and complications. The outcomes were assessed in the perioperative and 30-day follow-up periods. RESULTS: During a 33-month period, TCAR was completed in 147 of 149 attempted cases (98.7%). No patients required further revascularization. The perioperative and 30-day major adverse event rates were 0.7% (n = 1) and 3.4% (n = 5), respectively. One case of a minor perioperative CVA occurred. At 30 days, one patient had died. The 30-day complications included CVA (n = 1) and myocardial infarction (n = 3). The combined perioperative and 30-day minor complication rates were 2.7% and 1.4%, respectively. CONCLUSIONS: TCAR is a safe and effective method of carotid artery revascularization in a community hospital setting. This technology might help improve revascularization in patients without access to larger academic centers.

ABSTRACT: Thromboangiitis obliterans (TAO, Buerger disease) is a segmental, non-atherosclerotic vasculitis that causes occlusion of the small and medium sized vessels of the distal extremities. In rare cases, it can affect vessels in the gastrointestinal, cerebrovascular, coronary, and renal systems. The etiology of thromboangiitis obliterans is unknown, but there is a strong association with smoking in the development and the progression of the disease. We present the case of a 42-year-old homeless female smoker, who was found dead outdoors. Although originally suspected to be a possible trauma-related death, autopsy revealed a thrombus in her left carotid artery, which caused an acute cerebral infarction. It was concluded that thromboangiitis obliterans, likely precipitated by smoking, was the cause of the thrombosis and subsequent death.

BACKGROUND: Patients with gender dysphoria face significant health disparities and barriers to care. Transition-related care includes hormonal therapy, mental healthcare, and gender-affirming surgeries. Studies have described favorable surgical outcomes and patient satisfaction, however, the degree to which these procedures impact mental health conditions is not fully understood. The purpose of this study was to evaluate the effect of gender-affirming plastic surgery on mental health and substance abuse in the transgender population. METHODS: A national insurance claims-based database was used for data collection. Patients with a diagnosis of gender dysphoria were propensity score-matched for the likelihood of undergoing gender-affirming surgery (no surgery being the control cohort), based on comorbidities, age, and sex. Primary outcomes included post-operative antidepressant use and the prevalence of mental health conditions. RESULTS: A total of 3,134 patients with gender dysphoria were included in each cohort. Patients in the surgery group had overall lower rates of mental health conditions, substance abuse, and SSRI/SNRI use. There was an absolute decrease of 8.8% in SSRI or SNRI prescription after gender-affirming plastic surgery (p<0.001), and significant decreases in post-operative depression (7.7%), anxiety (1.6%), suicidal ideation (5.2%) and attempts (2.3%), alcohol abuse (2.1%), and drug abuse (1.9%). CONCLUSION: Gender-affirming surgery in appropriately selected gender dysphoric patients is associated with decreased postoperative rates of SSRI or SNRI use and improved mental health.
RESUMEN
BACKGROUND: This study aimed to determine the location of superficial fascial system (SFS) condensations in relation to classic anatomic breast boundaries. Cadaveric studies have provided some understanding, but knowledge about the precise location of these condensations remains limited. METHODS: Preoperative breast MRI was conducted to assess the fascial condensations defining the breast footprint relative to landmarks like the latissimus, clavicle, sternal border, and inframammary fold (IMF). Concurrently, cadaveric mastectomies were performed to measure the breast borders in relation to these landmarks for comparison. RESULTS: 290 breasts underwent preoperative MRI. Eight cadaveric breast dissections were completed. Radiographically, the lateral breast fascial condensation was 3.9 cm medial to the latissimus dorsi, while cadaveric measurements were 4.5 cm. The medial condensation was 2.1 cm lateral to the sternal border radiographically and 4.8 cm to midline in cadavers. The superior fascial condensation was 2.3 cm inferior to the clavicle radiographically and 5.5 cm by dissection. The inferior condensation was above the IMF in 82.7% of breasts by MRI and 100% of cadaveric breasts. MRI and cadaveric investigation showed similar patterns of breast tissue fascial condensations relative to standard breast boundaries. Breast skin flap thickness was greater peripherally (MRI: 11.5 mm, cadaver: 11.1 mm) than centrally (MRI: 6.6 mm, cadaver: 5.5 mm). CONCLUSIONS: MRI and cadaveric analysis demonstrated a close correlation between SFS and standard breast boundaries, although variations existed among subjects. Collaborating with breast oncologists and utilizing preoperative imaging to identify individual fascial condensations may enhance the camouflage of prepectoral implants after mastectomy.
RESUMEN
BACKGROUND: Transversus Abdominis Plane (TAP) blocks improve pain control and reduce narcotic medication requirements in various surgical procedures. Liposomal bupivacaine may provide more sustained analgesia. This study compares pain related outcomes between standard bupivacaine and liposomal bupivacaine TAP blocks after autologous breast reconstruction. METHODS: Prospective single-center, single-blinded, randomized controlled trial between March 2021 and December 2022. DIEP flap breast reconstruction patients in a standardized Enhanced Recovery After Surgery (ERAS) pathway were randomized to receive intraoperative TAPs with either bupivacaine / epinephrine (control) or liposomal bupivacaine / bupivacaine / epinephrine (experimental). Primary outcome was postoperative narcotic medication requirements, with secondary outcomes of pain scores, length of stay (LOS), and narcotic medication refills. RESULTS: 117 patients met inclusion criteria (59 control, 58 experimental). Patient demographics, comorbidities, breast pathologic variables, surgery laterality and immediate versus delayed reconstruction status were equivalent between groups. Control group had significantly higher average pain scores postoperatively (4.3 vs. 3.6, p=0.004). However, there were no significant differences in mean narcotic use (66.9 MME vs 60.2 MME, p=0.47). Both LOS and postoperative narcotic prescription refills were equivalent between groups (2.1 vs 2.2 days, p = 0.55, 22% vs 17.2%, p=0.52). CONCLUSION: Addition of liposomal bupivacaine to standard bupivacaine TAP block mixture in a standardized ERAS protocol did not demonstrate a significant reduction in postoperative narcotic requirements after DIEP flap breast reconstruction compared to standard bupivacaine alone. Patient-reported pain scores, however, were lower among liposomal bupivacaine patients after the initial 24 hours postoperatively and consistent with a longer duration of analgesia.
RESUMEN
BACKGROUND: Disparities in social determinants of health (SDH) have been shown to play an increasingly important role in the equitable delivery of health care. Distal radius fractures (DRFs) are among the most common upper-extremity injuries encountered. This study aims to examine the influence of economic, educational, social, environmental, and healthcare disparities on management of these injuries. METHODS: PearlDiver Mariner insurance claims database was analyzed for treatment patterns of DRF in patients aged 18 to 65 years based on the presence or absence of social determinants of health disparities (SDHDs). Outcome variables included the primary mode of management of DRF, including operative versus non-operative, as well as concomitant procedures. Multivariate logistic regression was used to compare fracture management modality in patients with and without SDHDs. RESULTS: Of 161 704 patients identified with DRF, 38.3% had at least 1 reported SDHD. The majority of SDHDs were economic. Patients identified with 1 or more SDHDs had a higher medical comorbidity index. Patients with environmental SDHD were more likely to receive non-operative management. Within any SDHD and economic subgroups, odds of operative management were higher. No relationship was identified between SDHD and concomitant procedures. CONCLUSIONS: The presence of environmental disparities in SDH may predispose patients disproportionately to non-operative management. The presence of SDHDs may influence medical decision-making in favor of open reduction and internal fixation in patients with DRF treated operatively. In treating at-risk populations, providers should be aware of the potential for implicit bias associated with SDHDs and prioritize shared decision-making between patients and physicians.
RESUMEN
BACKGROUND: Enhanced recovery after surgery (ERAS) pathways have been shown to improve pancreatic surgery outcomes, though feasibility in a community hospital remain unclear. We hypothesized that an ERAS protocol would reduce hospital length of stay (LOS) without increased morbidity. METHODS: An ERAS pathway was initiated for patients undergoing pancreatic surgery at a community cancer center and compared to a historical cohort. The primary outcome was hospital LOS. Secondary outcomes included 30-day readmission rates, comprehensive complication index (CCI®), textbook outcomes (TO), and mortality. RESULTS: A total of 144 patients were included, with 63 patients in the ERAS group and 81 in the control group. The mean LOS decreased significantly in the ERAS group (6.85 [± 4.8]) vs 9.96 [±6.8] days, P = .001), without an increase in 30-day admission rates or CCI. CONCLUSIONS: Implementation of an ERAS protocol in a community setting reduced LOS without a corresponding increase in readmission rates or morbidity.

Background: Surgical site infection (SSI) surveillance programs are recommended to be included in national infection prevention and control (IPC) programs, yet few exist in low- or middle-income countries (LMICs). Our goal was to identify components of surveillance in existing programs that could be replicated elsewhere and note opportunities for improvement to build awareness for other countries in the process of developing their own national surgical site infection surveillance (nSSIS) programs. Methods: We administered a survey built upon the U.S. Centers for Disease Control and Prevention's framework for surveillance system evaluation to systematically deconstruct logistical infrastructure of existing nSSIS programs in LMICs. Qualitative analyses of survey responses by thematic elements were used to identify successful surveillance system components and recognize opportunities for improvement. Results: Three respondents representing countries in Europe and Central Asia, sub-Saharan Africa, and South Asia designated as upper middle-income, lower middle-income, and low-income responded. Notable strengths described by respondents included use of local paper documentation, staggered data entry, and limited data entry fields. Opportunities for improvement included outpatient data capture, broader coverage of healthcare centers within a nation, improved audit processes, defining the denominator of number of surgical procedures, and presence of an easily accessible, free SSI surveillance training program for healthcare workers. Conclusions: Outpatient post-surgery surveillance, national coverage of healthcare facilities, and training on how to take local SSI surveillance data and integrate it within a broader nSSIS program at the national level remain areas of opportunities for countries looking to implement a nSSIS program.

BACKGROUND: The extent to which age impacts surgical outcomes remains poorly characterized. This study aims to evaluate the impact of age on 30-day outcomes in patients after distal pancreatectomy. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2017), distal pancreatectomy patients were identified and age-stratified, groups A (≤75 years) and B (>75 years). Outcomes included 30-day mortality, morbidity, readmissions, operative time (min), and hospital length of stay (LOS, days). RESULTS: Of 3042 total patients identified, 1686 (55.4%) were women. A total of 2649 patients (87.1%) were in group A. Overall, both groups had similar baseline characteristics with the exception of the following: diabetes mellitus (24.8% vs. 30.0%, P = .03), smoking (19.3% vs. 4.8%, P < .001), congestive heart failure (.5% vs. 1.8%, P = .010), hypertension (HTN) (47.9% vs. 72.5%, P < .001), bleeding disorders (3.1% vs. 5.3%, P = .036), the American Society of Anesthesiologists (ASA) (III-V) scores (67.6% vs. 85.5%, P < .001), and body mass index (29.2 [±6.7] vs. 27.4 [±5.6], P = .001).Deep surgical site infection was higher in group A (12.1% vs. 6.6%, P = .001), while acute renal failure (ARF) and postoperative myocardial infarction (MI) were higher in group B. 30-day readmissions were higher in group A (17.4% vs. 12.2%, P = .011) despite no statistically significant difference in LOS (7.10 [±6.36] vs. 7.30 [±4.93] days, P = .553) or overall morbidity (29.4% vs. 28.8%, P = .859). CONCLUSION(S): Those undergoing distal pancreatectomy experienced similar overall morbidity and mortality outcomes regardless of age. However, those older than 75 years had more cardiovascular risk factors, which may have contributed to their higher rates of postoperative ARF and MI.

Background: Pseudomonas aeruginosa is isolated at variable rates from intra-abdominal infections (IAI). Not all recommended empiric regimens for IAI include anti-Pseudomonas aeruginosa activity, for example, ceftriaxone and metronidazole. We hypothesized that within an adult population, Pseudomonas aeruginosa is a relatively rare isolate and has no association with mortality, and thus, empiric therapy with anti-Pseudomonas aeruginosa activity is not warranted. Patients and Methods: All IAI with positive cultures treated between 1997 and 2017 at a single institution were analyzed. This data set was divided into two cohorts, namely, those with cultures positive for Pseudomonas aeruginosa and those without. Demographics and in-hospital mortality were compared by Student t-test and χ2 analysis. Predictors of isolation of Pseudomonas aeruginosa and in-hospital mortality were done by logistic regression (LR) analysis. Results: In total, 2,420 IAIs were identified, 104 (4.3%) with Pseudomonas aeruginosa and 2,316 (95.7%) without. Major demographic differences between patients with Pseudomonas aeruginosa and those without included a higher rate of health-care-associated infections (87/104, 83.7% vs. 621/2316, 26.8%; p = 0.02), a higher rate of intensive care unit (ICU)-acquired infections (23/104, 22.1% vs. 329/2316, 14.2%; p = 0.04) and a higher Acute Physiology and Chronic Health Evaluation (APACHE) II score (17.7 ± 0.8 vs. 14.5 ± 0.2; p < 0.0001). There was an increased rate of Pseudomonas aeruginosa isolation with increasing APACHE II score. Independent predictors of isolation of Pseudomonas aeruginosa by LR included APACHE II score and days of hospitalization prior to diagnosis. Crude in-hospital mortality was similar between groups: Pseudomonas aeruginosa 14/104 (13.5%) and 276/2316 (11.9%), p = 0.79. After controlling for age, gender, APACHE II, prior transfusion, immunosuppression status, solid organ transplant status, healthcare-association, and days of hospitalization prior to diagnosis, the isolation of Pseudomonas aeruginosa was not associated with mortality. Conclusion: Pseudomonas aeruginosa is infrequently isolated and overall not associated with mortality. Nonetheless, there may be a population that merits empiric anti-Pseudomonas aeruginosa therapy: those with APACHE II ≥20 or a significant length of hospitalization prior to diagnosis.

Despite the well-established relationship between volume and outcomes, patients continue to have procedures performed at low-volume hospitals. The factors patients use to make the complex decision of where to have hepatopancreaticobiliary (HPB) surgery remain poorly characterized. A novel survey instrument was administered to all patients who had undergone HPB surgery at two university-affiliated community hospitals. 76 patients participated in the study (89% response rate). The majority of patients were unaware of the volume-outcome relationship (58.8%). No demographic factors differed between patients who were or were not aware except for patient research. Physician factors were the most important selection category (64.4%). Only 28.9% of patients were willing to travel more than two hours to have an operation performed at a hospital with a high volume/improved quality. Despite many voices calling for regionalization, patient decision-making factors should be considered before any realistic implementation.
RESUMEN
BACKGROUND: Over the past several decades, improvements in technology in the Neonatal Intensive Care Unit (NICU) have led to improved survival of preterm infants. Some studies have found that premature infants are at higher risk of behavioral problems, motor and sensory abnormalities, developmental delay, and poorer academic performance, while other studies have found no significant difference. METHODS: A literature search was conducted through PubMed for articles published between January 2018 and September 2019. Studies that concentrated on preterm infants with relatively uncomplicated NICU courses and without extensive medical interventions were selected. RESULTS: Historically, preterm infants have been found to be at increased risk for the inattentive subtype of attention deficit hyperactivity disorder (ADHD), depression, anxiety, autism spectrum disorder (ASD), avoidant personality, and anti-social personality, when compared to full term infants. However, some studies found that this difference between the two groups decrease as they enter adolescence and adulthood. Preterm infants are at increased risk for language, cognitive, sensory and motor deficits. Greater gestational age (GA) at birth and higher birth weight is associated with a lower risk of developmental delay. Cohort studies focusing on motor development showed that the degree of impairment decreased over time. Adverse childhood experiences (ACEs) have a negative correlation on multiple domains of development. The overall outcome of these infants may be influenced by socioeconomic status (SES), neonatal morbidities, demographics and parental education. Hearing and vision deficits are relatively infrequent among premature infants. A significant risk factor for hearing impairment involves the use of ototoxic agents such as gentamicin and infants with a patent ductus arteriosus (PDA). CONCLUSIONS: Preterm infants are at higher risk of adverse neurodevelopmental outcomes when compared to their full-term counter parts. However, in recent years it appears that rates of certain neurologic and developmental conditions are occurring in rates lower than historically noted. Premature individuals with possible developmental or mental health concerns should be identified early on so that interventions can be implemented immediately. Those meeting developmental milestone should continue to be monitored closely as deficits may develop later.
RESUMEN
BACKGROUND: Most recurrences of early stage cervical cancer occur in the pelvis or lymphatic system. Distant metastases occur in a minority of patients. Large abdominal wall recurrence presenting as cellulitis and intra-abdominal mass is unusual and presents diagnostic as well as treatment challenges. CASE: A 46-year-old woman with a history of stage 1B1 poorly differentiated squamous cell carcinoma of the cervix 2 years earlier presented with infraumbilical abdominal wall erythema, tenderness and warmth to the touch. She had a subcutaneous mass in that area with associated abdominopelvic pain. Imaging showed a 9.5 × 11 cm lobulated mass in the anterior lower abdominal wall, encompassing the width of the lower rectus muscles also invading the small bowel and the bladder. Superimposed cellulitis led to the symptoms with which she presented. She was treated with intravenous antibiotics, and biopsy of the mass revealed squamous cell carcinoma consistent with her prior cervical cancer. She was treated with neoadjuvant chemotherapy followed by surgical debulking with negative margins and adjuvant chemotherapy. Three months after completing treatment she recurred in the inguinal lymph nodes and restarted multimodality treatment. She was without evidence of disease for the entire 18 months of follow up following treatment to the lymph nodes. CONCLUSION: Cervical cancer recurrence patterns can be unique. Surveillance for recurrence may also include consideration of these unusual patterns of recurrence.
RESUMEN
BACKGROUND: Preoperative carbohydrate loading is a recommended component of enhanced recovery protocols (ERP's), however the impact on postoperative stress-induced insulin resistance remains poorly studied in both diabetics and non-diabetics. METHODS: Using our ERP, a preoperative grape juice group (Grape) was compared to the use of 25â¯g maltodextrin/3â¯g citrulline (G.E.D.™, SOF Health, LLC) for carbohydrate loading. RESULTS: The population included 171 patients (Grape nâ¯=â¯96; GED nâ¯=â¯75). Glycemic variability was significantly worse for the Grape group on POD 0 in both non-diabetic (70% vs 41%; pâ¯<â¯0.05) and diabetic patients (66% vs 34%; pâ¯<â¯0.05). Significantly more Grape patients required postoperative insulin regardless of diabetic status. CONCLUSION: Following bariatric surgery, the impact of stress induced hyperglycemia is primarily on POD 0 in non-diabetics whereas the effect extends into POD 1 for diabetics. Preoperative loading with G.E.D.™ versus grape juice is associated with a significantly lower rate of glycemic variation and postoperative insulin requirement, demonstrating that drink composition and treatment process reduces the severity of postoperative stress induced hyperglycemia in bariatric surgery patients.

Cyclic nucleotide phosphodiesterases (PDE) break down cyclic nucleotides such as cAMP and cGMP, reducing the signaling of these important intracellular second messengers. Several unique families of phosphodiesterases exist, and certain families are clinically important modulators of vasodilation. In the current work, we have summarized the body of literature that describes an emerging role for the PDE4 subfamily of phosphodiesterases in malignancy. We have systematically investigated PDE4A, PDE4B, PDE4C, and PDE4D isoforms and found evidence associating them with several cancer types including hematologic malignancies and lung cancers, among others. In this review, we compare the evidence examining the functional role of each PDE4 subtype across malignancies, looking for common signaling themes, signaling pathways, and establishing the case for PDE4 subtypes as a potential therapeutic target for cancer treatment.

Background: Surgical site infection (SSI) surveillance programs are strongly recommended as a core component of effective national infection prevention and control (IPC) programs. Participation in national SSI surveillance (nSSIS) programs has been shown to decrease reported SSIs among high-income countries (HICs), and it is expected that the same is possible among low- and middle-income countries (LMICs). We sought to determine what, if any nSSIS programs exist among LMICs. Methods: A cross-sectional survey was performed to evaluate existence of nSSIS of World Bank-defined LMICs. A digital survey assessment for presence of national IPC and nSSIS programs was delivered to persons capable of identifying the presence of such a program. Statistical analysis was performed using STATA. Institutional Review Board approval was obtained for this study. Results: Of the 137 countries identified, 55 (40%) were upper middle income (UMI), 47 (34%) were lower middle income (LMI), and 34 (25%) were low income. Representatives from 39 (28%) LMICs completed the survey. Of these respondent countries, 13 (33%) reported the presence of a national IPC program. There was no difference between countries with IPC programs and those without with respect to country income designation, population size, World Health Organization region, or conflict status. Only five (13% of all respondents) reported presence of a nSSIS program. Conclusions: National surgical site infection surveillance programs are an integral component of a country's ability to provide safe surgical procedures. Presence of nSSIS was reported infrequently in LMICs. International governing bodies should be encouraged to guide LMIC leadership in establishing a nSSIS infrastructure that will help enable safe surgical procedures.

BACKGROUND: Intrahepatic cholangiocarcinoma (IHC) is a malignancy with an increasing incidence. Surgery is the only treatment modality associated with long term survival. The objective of this study is to utilize a nationwide representative database to quantify the trends in incidence, and surgery for IHC in the United States from 2004-2014, as well as identify any disparities in the receipt of surgery. METHODS: All patients admitted with a diagnosis of IHC between 2005 and 2014 were identified from the Nationwide Inpatient Sample (NIS) database. Trends in the number of IHC admissions and surgery procedures as well as outcomes were examined, and a multivariate analysis was used to determine the effects of demographic and clinical co-variables on resection rates. RESULTS: An estimated total of 104,045 IHC related admissions occurred between 2005 and 2014. The hospitalization rate for IHC increased by nearly 2-fold in 2014 [38.9 per 100,000 (95% CI, 35.7-42.2)] from 18.1 per 100,000 (95% CI, 15.8-20.3) in 2005. Liver resections increased 248% (P<0.01) with an increasing majority being performed at teaching hospitals and 56% being minor resections. There was an increase in estimated hospital charges from $87,124 to $148,613 (P<0.001) and decrease in LOS from 12 days to 10 days (P<0.01). Inpatient mortality for IHC decreased significantly from 11% to 8.4% (P=0.004), from year 2005 to 2014 respectively. Age >80 years (OR =0.45; 95% CI, 0.33-0.60), Black race (OR =0.50; 95% CI, 0.39-063), Hispanic race (OR =0.59; 95% CI, 0.45-0.79), Medicaid insurance (OR =0.58; 95% CI, 0.42-0.79) and Elixhauser comorbidity score >3 (OR =0.58; 95% CI, 0.47-0.73) were associated with decreased rates of resection. CONCLUSIONS: Overall hospitalization and volume of surgery for IHC has increased dramatically over the past decade. There has been an increase in cost, decrease in LOS and inpatient mortality during the period. Socioeconomic and racial disparities were observed in the receipt of surgery for IHC. Additional work is needed to understand the complex interplay between socioeconomic status and race in in the treatment of IHC.
