Cancer Diagnoses during Active Conflict: Experience from a Cancer Program in Northwest Syria.

Background Protracted conflict has destroyed Syria's health system with severe impacts on the diagnosis and treatment of chronic and high-cost diseases including cancer. Here, we review the type and (where possible) the stage of cancers diagnosed in a pathology laboratory serving Northwest Syria. Methods We retrospectively reviewed all pathology reports which reported a diagnosis of cancer from a pathology department in Northwest Syria from January to December 2020. Results A total of 397 new cancers were diagnosed during 2020 of which 191 were among males (48.1%) and 20 cases were in children aged 17 years or under (5%). The most common cancer in men was bladder cancer (15.7%) and skin cancers (14.7%) followed by cancers in the lymph nodes (includes primary and secondary; 9.9%.) In women, breast cancer (38.3%) followed by skin cancer skin (9.7%) and uterine cancer (8.7%) was the most common. The overall proportion of cancer diagnoses were breast cancer (20.2%), skin cancer (12.1%), cancer affecting lymph nodes (8.8%), and urinary bladder (8.3%) and colorectal cancer (7.3%). Discussion This preliminary analysis is the first report of cancer types and demographics in areas outside of government control in Syria since the onset of the conflict. Despite limitations, it presents some indication of the burden of oncological diagnoses in this area. Further research which aims to describe and address the burden of cancer on populations under ongoing conflict and humanitarian crises remains essential, especially in Northwest Syria given ongoing attacks and severe underfunding. There is a particular need to investigate how best to apply interventions and support health systems and cancer services within conflict settings. More support and resources need to be allocated to cancer centers with long-term health partnership models. The underresourced and understaffed conditions of the hospital are significant limits to a more detailed report.

Protracted armed conflict and maternal health: a scoping review of literature and a retrospective analysis of primary data from northwest Syria.

INTRODUCTION: Syria's protracted conflict has devastated the health system reversing progress made on maternal health preconflict. Our aim is to understand the state of maternal health in Syria focused on underage pregnancy and caesarean sections using a scoping review and quantitative analysis; the latter draws on data from the Syrian American Medical Society's (SAMS) maternal health facilities in northwest Syria. METHODS: We performed a scoping review of academic and grey literature on the state of maternal health across Syria since the onset of conflict (taken as March 2011). Identified articles were screened using pre-established criteria and themes identified. We also performed a retrospective quantitative analysis of maternal health data from SAMS' facilities in a microcontext in north-west Syria between March 2017 and July 2020, analysing the trends in the proportion of births by caesarean section and age at pregnancy. RESULTS: Scoping review: of 2824 articles, 21 remained after screening. Main themes related to maternal mortality rates, caesarean sections, maternal age and perinatal care. 12 studies reported caesarean section rates; these varied from 16% to 64% of all births: northern Syria (19%-45%,) Damascus (16%-54%,) Lattakia (64%) and Tartous (59%.) Quantitative analysis: Of 77 746 births across 17 facilities, trend data for caesarean sections showed a decrease from 35% in March 2017 to 23% in July 2020 across SAMS facilities. Girls under 18 years accounted for 10% of births and had a lower proportion of caesarean section births. There was notable geographical and interfacility variation in the findings. CONCLUSION: The quality of available literature was poor with country-level generalisations. Research which explores microcontexts in Syria is important given the different effects of conflict across the country and the fragmented health system. Our quantitative analysis provides some evidence around the changes to caesarean section rates in northwest Syria. Despite limitations, this study adds to sparse literature on this important topic.

Prevalence and clinical features of patients with autoimmune pancreatitis and inflammatory bowel disease: A systematic review and meta-analysis.

BACKGROUND AND AIM: Autoimmune pancreatitis (AIP) and inflammatory bowel disease (IBD) are categorized into immune-mediated inflammatory disorders (IMIDs). While AIP is a pancreato-biliary IMID with an increased incidence and prevalence among patients with IBD, its features are still unclear. This systematic review and meta-analysis aims to assess the prevalence and clinical characteristics of AIP-IBD patients. METHODS: Electronic databases were searched to identify observational studies assessing AIP and IBD. The primary outcome was the prevalence of IBD among AIP patients, and vice versa. Secondary outcomes included clinical findings and outcomes of each IMID in AIP-IBD patients. The pooled rate of each outcome was determined using a random effects model. RESULTS: For primary outcomes, 40 observational studies with 4031 AIP patients were included and the pooled prevalence of IBD was 10.5% (95% CI 7.2-15.0%). Meanwhile, five studies with 10,551 IBD patients were included and the pooled prevalence of AIP was 0.6% (95% CI 0.2-1.9%). For secondary outcomes, 53 observational studies with 469 AIP-IBD patients were assessed. The rates of type 2 AIP and ulcerative colitis were 79.2% (95% CI 69.1-86.6%) and 74.8% (95% CI 68.2-80.4%), respectively. We also demonstrated AIP-IBD patients were at a significant increased risk of AIP recurrence and colectomy compared with patients with either AIP or IBD (RR = 1.9, 95% CI 1.1-3.1 and P = 0.014 and RR = 3.7, 95% CI 1.9-6.9, P < 0.001, respectively). CONCLUSIONS: Our meta-analysis reported the prevalence of AIP-IBD patients and demonstrated patients with both IMIDs had a high risk of poor outcomes.

P014 Postoperative Recurrence in Crohn's Disease Patients Treated with Adalimumab versus Infliximab: A Systematic Review and Meta-Analysis.

BACKGROUND: Up to 80% of patients with Crohn's disease (CD) undergo intestinal resection at one point. However, the risk of post-operative recurrence (POR) increases with time, with half of these patients developing recurrence at five years after surgery. Treatment with anti-tumor necrosis factor (anti-TNF) agents has been shown to decrease the risk of clinical and endoscopic recurrence post-operatively. This meta-analysis aims to compare the rate of the two mostly commonly used anti-TNF agents (infliximab (IFX) and adalimumab (ADA)) and their efficacy in maintaining clinical and endoscopic remission in CD patients who were treated with adalimumab versus infliximab after surgery. METHODS: A comprehensive search of Medline, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Scopus was conducted from each database's inception to May 29th 2021. Comparative studies assessing the efficacy and safety of infliximab and adalimumab for postoperative CD patients were included. Primary outcomes included postoperative clinical and endoscopic remission. Secondary outcome was the risk of adverse events due to anti-TNF agents. Pooled event rates were calculated per person-year of follow-up. RESULTS: Four studies with total of 361 CD patients were included in the final analysis. Our meta-analysis showed no statistically significant difference in maintaining clinical and endoscopic remission rates between patients treated with infliximab and those with adalimumab (Pooled incidence rate ratio of 0.75 (95% CI 0.43-1.3), and 0.94 (95% CI 0.71-1.2), respectively) (Figure 1A, 2A). There were low to moderate heterogeneities (I2 = 57.1% for clinical remission and I2 = 0% for endoscopic remission). The funnel plot in each analysis indicated no publication bias, which was supported by Begg's and Egger's tests (Figure 1B, 2B). There was also no significant difference in the risk of adverse events between the two groups (RR= 0.56, 95% CI 0.068-4.5) (Figure 3). CONCLUSION: Our meta-analysis demonstrated comparable efficacy of infliximab and adalimumab in maintaining post-operative clinical and endoscopic remission in Crohn's disease, with similar rates of adverse events. Our meta-analysis was limited by the small number of total studies and patients included and the lack of randomized controlled trials.

Appraising the outcome and complications of peritoneal dialysis patients in self-care peritoneal dialysis and assisted peritoneal dialysis: A 5-year review of a single Saudi center.

Our objective is to study the outcomes and complications of peritoneal dialysis (PD) including comparison of self-care PD with home-care assisted PD during a five-year period. A retrospective study of PD data at King Saud University-affiliated hospital in Riyadh from January 1, 2009, to December 31, 2013. One hundred and eleven patients were included (female 55%). The average age was 47.4 (1-83) years. Twenty-one (18.91%) patients were on continuous ambulatory PD and 90 (81.08%) on automated PD. The mean time on PD was 23.5 (3-60) months. At the end of five years, 47 (42.34%) patients were continuing on PD, 12 (10.81%) had renal transplant, 33 (29.73%) patients were transferred to hemodialysis, and two (1.8%) patients were transferred to other centers. Seventeen patients died during this period giving a mortality rate of 7.13 deaths/100 patient-year during the five-year period. Six patients died due to cardiovascular causes, while five had sepsis. There was one death each due to prostate cancer, hyperoxaluria, and toxic epidermal necrolysis. Three patients died suddenly at home. Peritonitis rate was one episode/35.28 patient/month or one episode/2.94 patient/year. We compared the results for patients doing the dialysis themselves [56 (50.45%)] "self-care PD" to 55 (49.5%) patients assisted by a family member or other caregivers "assisted PD." We found no significant difference in the incidence of complications, technical outcome, mortality, and peritonitis episodes. However, we found a high prevalence of diabetes mellitus and significant increase in exit site infection in assisted PD. Our study suggests that PD patients in Saudi Arabia have a good overall outcome. Furthermore, assisted PD showed good patient and technique outcome.

Glomerular necrotic lesions and long-term outcomes among patients with proliferative lupus nephritis.

OBJECTIVES: Although necrotic lesions are common in proliferative lupus nephritis (LN), little is known about the impact of these lesions on outcomes. This study was undertaken to investigate the impact of glomerular necrotic lesions on renal outcomes of doubling serum creatinine in patients with class III and IV LN and necrotic lesions. METHODS: 52 patients with ISN/RPS class III or IV LN were enrolled in this retrospective study, with mean follow-up of 7.4 years. All patients underwent a repeat biopsy at 12-18 months after a baseline biopsy. RESULTS: The prevalence of necrotizing lesions was observed in 24% of those with class III versus 70.4% with class IV (P=0.001). The rate of no remission was 44% and 22.2% in those with and without necrosis (P=0.007), respectively. The doubling of serum creatinine was observed in 32% of those with necrosis and in 14.8% with no necrosis (P=0.01). The chronicity index in the repeat biopsy was significantly worse among those with necrosis. CONCLUSIONS: Glomerular necrosis identifies lupus nephritis patients at the greatest risk for progression to renal failure. Proactive intervention and possibly more aggressive induction therapies in patients with necrotizing lesions may protect the kidneys from developing chronic renal impairment.

Hepatobiliary scintigraphy as a diagnostic modality for gastroparesis of the bypassed stomach after gastric bypass for morbid obesity.

After Roux-en-Y gastric bypass (RYGBP), the excluded gastric remnant represents a challenge for the surgeon. Many diseases are reported to take place in that remnant, such as cancer, gastritis, and ulcer. On the other hand, diagnosing these pathological changes requires invasive intervention. We report the use of a noninvasive study to diagnose pathology in the bypassed stomach.

Should axillary artery to coronary artery bypass be part of the cardiac surgeon's armamentarium?

BACKGROUND: The axillary artery has been used as an alternate inflow source for revascularization of the lower extremities for four decades. Since 1997, there have been several reports of axillary artery to coronary artery bypass. METHODS: All cases of axillary artery to coronary artery bypass at our institution from 1997 through 2003 were reviewed. PubMed was queried for publications on this subject and all pertinent reports were reviewed. RESULTS: Thirty-eight patients underwent axillary artery to coronary artery bypass at our hospital. Most (34) of the operations were performed without cardiopulmonary bypass. Saphenous vein (37) or radial artery (1) grafts were placed to one or more coronary arteries from either the left (36) or right (2) axillary artery. Twenty patients underwent sternotomy, and 18 had either a left (16) or right (2) minimally invasive direct coronary artery bypass (MIDCAB) procedure performed. Most of the sternotomies were for primary myocardial revascularization and most of the MIDCABs were reoperations. There were three deaths-all from non-cardiac causes, one myocardial infarction, and one transient brachial plexus injury. Doppler ultrasound, angiographic, and clinical follow-up were limited, but graft patency has been demonstrated up to 9 years. CONCLUSION: Axillary artery to coronary artery bypass should be part of the armamentarium of surgeons who perform myocardial revascularization operations.

The risk of carotid endarterectomy in patients with chronic renal insufficiency.

OBJECTIVE: Carotid endarterectomy (CEA) has been associated with less favorable outcome in patients with chronic renal insufficiency (CRI). The authors compared results of CEA in the presence and absence of CRI at their institution over a 5-year period. DESIGN/SETTING/PARTICIPANTS: This article is a retrospective review of 1351 patients who underwent CEA between 1998 and 2004. Chronic renal insufficiency was present in 143 patients. Renal insufficiency was graded as mild (creatinine 1.6-2.9 mg/dL) or severe (creatinine > or = 3.0 mg/dL or on hemodialysis). The composite endpoint was stroke or death within 30 days postoperatively. The results were compared with 150 consecutive patients having CEA in the absence of renal insufficiency between 2002 and 2003. RESULTS: For the 143 patients with CRI, the composite endpoint was 9.0%, whereas the composite endpoint for the 150 control patients without CRI was 2.6% (p = 0.032). For patients with severe CRI (creatinine > or = 3.0 or on hemodialysis), the composite endpoint was 19.0% (p = 0.08). For those with mild CRI (creatinine 1.6-2.9), the composite endpoint was 7.3% (p = 0.06). CONCLUSIONS: Chronic renal insufficiency is associated with increased incidence of stroke, myocardial infarction, and death after CEA. For patients with advanced CRI, carotid artery stenting (CAS) or aggressive medical management may be alternative treatment options.
