Predictive factors and quality of life assessment among patients with spinal cord injury in the Middle East: a systematic review.

PURPOSE: Spinal cord injury (SCI) is impairment of the spinal cord that adversely affects patients' health and quality of life (QoL). The aim of the study was to assess the quality of life (QoL) and related factors in patients with traumatic spinal cord injury in Middle Eastern countries. METHODS: PubMed, Ovid Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EBSCOhost, psycINFO, and Google Scholar were systematically searched for eligible studies published in peer-reviewed journals up till October 2023. RESULTS: Out of 1060 papers found in the literature, only 18 studies from Iran, Lebanon, and Turkey met the inclusion criteria. The majority of the studies employed the SF-36 scale to assess for QoL. In general, all SCI patients had reduced QoL scores when compared to the healthy population. Some of the factors such as age, education level, the level of injury, time since injury onset, marriage, and job opportunities were correlated with SCI subjects QoL. Our papers were assessed and found to be of both good and high quality. CONCLUSION: This review emphasizes the significant shortage of QoL studies among SCI patients in the Middle East countries and highlights the importance of improving the QoL of this marginalized population. This work should enhance the governments to establish rehabilitation centers, social and economic support systems, and mental health services to diminish complications arising from SCI.

Assessing Surgical Outcomes for Cage Plate System versus Stand-Alone Cage in Anterior Cervical Discectomy and Fusion: A Systematic Review and Meta-Analysis.

BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a common surgical procedure for addressing cervical spine conditions. It involves the utilization of either cage plate system (CPS) or stand-alone cage (SC). The objective of our study is to compare perioperative complications, patient-reported clinical outcomes measures, and radiographic outcomes of SC versus CPS in ACDF. METHODS: We carried out a literature search in PubMed, Embase, Cochrane library, Web of science, Medline, and Google Scholar. All studies comparing the outcomes between CPS versus SC in ACDF were included. RESULTS: Forty-one studies, 33 observational and 8 randomized clinical trials met the inclusion criteria. We found that both devices demonstrated comparable effectiveness in monosegmental ACDF with respect to Japanese Orthopedic Association Score, Neck Disability Index score, visual analog score, and fusion rates. CPS demonstrated superior performance in maintaining disc height, cervical lordosis, and exhibited lower incidence rates of cage subsidence. SC showed significant advantages over CPS in terms of shorter surgical duration, less intraoperative bleeding, shorter duration of hospitalization, as well as lower incidence rates of early postoperative dysphagia and adjacent segment disease. CONCLUSIONS: Most of the included studies had monosegmented fusion, and there wasn't enough data to set recommendations for the multisegmented fusions. Larger studies with longer follow-up are necessary to draw more definitive conclusions to provide evidence for clinicians to make clinical decisions.

Regulatory B Cells in Solid Organ Transplantation: From Immune Monitoring to Immunotherapy.

Regulatory B cells (Breg) modulate the immune response in diverse disease settings including transplantation. Despite the lack of a specific phenotypic marker or transcription factor, their significance in transplantation is underscored by their ability to prolong experimental allograft survival, the possibility for their clinical use as immune monitoring tools, and the exciting prospect for them to form the basis for cell therapy. Interleukin (IL)-10 expression remains the most widely used marker for Breg. Several Breg subsets with distinct phenotypes that express this "signature Breg cytokine" have been described in mice and humans. Although T-cell immunoglobulin and mucin family-1 is the most inclusive and functional marker that accounts for murine Breg with disparate mechanisms of action, the significance of T-cell immunoglobulin and mucin family-1 as a marker for Breg in humans still needs to be explored. Although the primary focus of this review is the role of Breg in clinical transplantation, the net modulatory effect of B cells on the immune response and clinical outcomes is the result of the balancing functions of both Breg and effector B cells. Supporting this notion, B-cell IL-10/tumor necrosis factor α ratio is shown to predict immunologic reactivity and clinical outcomes in kidney and liver transplantation. Assessment of Breg:B effector balance using their IL-10/tumor necrosis factor α ratio may identify patients that require more immunosuppression and provide mechanistic insights into potential therapies. In summary, current advances in our understanding of murine and human Breg will pave way for future definitive clinical studies aiming to test them for immune monitoring and as therapeutic targets.

Cervical intradural traumatic neuroma without history of trauma: illustrative case.

BACKGROUND: Traumatic neuroma typically refers to a reactive process in the injured peripheral nerve, characterized by an excessive growth of axons, Schwann cells, and fibroblasts at the proximal end of the nerve after its interruption. The authors report a case of a traumatic neuroma in the cervical nerve root in a patient with no history of trauma. OBSERVATIONS: The patient presented with sensation loss in the right-hand ulnar distribution, right flank around the T4-11 region, and right small toe along with motor power weakness over the right upper and lower extremity. Magnetic resonance imaging revealed an intradural extramedullary mass lesion with extension along the C7 nerve root. Histological examination showed traumatic neuroma. A total resection of the lesion along with the resolution of sensory and motor deficits was achieved directly after surgery. LESSONS: Traumatic neuroma should always be kept in the armamentarium for diagnosis of an intradural nerve sheath tumor.

Racial Disparities and Surgical Outcomes After Anterior Cervical Discectomy and Fusion: National Surgical Quality Improvement Program Analysis 2015-2020.

BACKGROUND: Our objective was to assess the effect of race on outcomes in patients undergoing anterior cervical discectomy and fusion (ACDF). METHODS: We identified 57,913 adult patients who underwent elective ACDF spine surgery from 2015 to 2020. Data were extracted from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Demographics, comorbidities, perioperative course, and 30-day postoperative outcomes were stratified by race. RESULTS: A total of 57,913 patients, white (n = 49,016), African American (AA; n = 7200), Native American (NA; n = 565), and Asian (n = 1132) underwent ACDF fusion surgery. AA patients had higher comorbidities, including diabetes (24.7%), dyspnea (5.9%), and hypertension (61.6%) compared with the other groups (P < 0.001). NA and AA were higher tobacco users, (33.1%) and (28.7%), respectively (P < 0.001). Most of the patients reported in this dataset had single-level surgeries. AAs had a longer average hospital stay (2.51±7.31 days) and operative time (144.13±82.26 min) (P < 0.001). Lower risk of superficial surgical site infection (adjusted odds ratio [ORadj], 0.41; 95% confidence interval [CI], 0.22-0.77; P = 0.005) and greater risk of reintubation (ORadj, 1.65; 95% CI, 1.25-2.17; P < 0.001), pulmonary embolism (ORadj, 1.88; 95% CI, 1.27-2.79; P = 0.001), renal insufficiency (ORadj, 3.15; 95% CI, 1.38-7.20; P = 0.006), and return to the operating room (ORadj, 1.41; 95% CI, 1.18-1.65; P < 0.001 were reported in AAs compared with whites. NAs showed an increased risk of superficial surgical site infection compared with whites (ORadj, 2.59; 95% CI, 1.05-6.36; P = 0.037). CONCLUSIONS: Racial disparities were found to independently affect rates of complications after surgery for ACDF.

Well-differentiated gastro-entero-pancreatic neuroendocrine tumors with positive FDG-PET/CT: a retrospective chart review.

PURPOSE: Rarely, well-differentiated gastro-entero-pancreatic neuroendocrine tumors (GEP NETs) can have positive uptake on 18F-fluorodeoxyglucose-PET/computerized tomography ( 18 F-FDG-PET/CT), with or without a positive 68 Ga-PET/CT. We aim to evaluate the diagnostic role of 18 F-FDG-PET/CT in patients with well-differentiated GEP NETs. METHODS: We retrospectively reviewed a chart of patients diagnosed with GEP NETs between 2014 and 2021, at the American University of Beirut Medical Center, who have low (G1; Ki-67 ≤2) or intermediate (G2; and Ki-67 >2-≤20) well-differentiated tumors with positive findings on FDG-PET/CT. The primary endpoint is progression-free survival (PFS) compared to historical control, and the secondary outcome is to describe their clinical outcome. RESULTS: In total 8 out of 36 patients with G1 or G2 GEP NET met the inclusion criteria for this study. The median age was 60 years (range 51-75 years) and 75% were male. One patient (12.5%) had a G1 tumor whereas 7 (87.5%) had G2, and seven patients were stage IV. The primary tumor was intestinal in 62.5% of the patients and pancreatic in 37.5%. Seven patients had both 18 F-FDG-PET/CT and 68 Ga-PET/CT positive and one patient had a positive 18 F-FDG-PET/CT and negative 68 Ga-PET/CT. Median and mean PFS in patients positive for both 68 Ga-PET/CT and 18 F-FDG-PET/CT were 49.71 months and 37.5 months (95% CI, 20.7-54.3), respectively. PFS in these patients is lower than that reported in the literature for G1/G2 NETs with positive 68 Ga-PET/CT and negative FDG-PET/CT (37.5 vs. 71 months; P = 0.0217). CONCLUSION: A new prognostic score that includes 18 F-FDG-PET/CT in G1/G2 GEP NETs could identify more aggressive tumors.

Maintenance chemotherapy in advanced and metastatic pancreatic cancer, a narrative review and case series.

Limited data exist on the management of patients with locally advanced (aPC) or metastatic pancreatic (mPC) cancer who achieve stable disease/response after first-line chemotherapy. In this setting, maintenance therapy is important to minimize toxicity while preserving survival benefits. The aim of this study is to conduct a narrative review of the evidence available on the topic and present the results of a retrospective case series of patients with aPC or mPC who received maintenance therapy following a good response to induction chemotherapy. Olaparib is the only drug approved for maintenance therapy in patients with metastatic pancreatic cancer and germline Breast Cancer gene mutation. Data from several trials, including the phase II PANOPTIMOX-PRODIGE35 trial, showed clinical benefit from the use of 5-fluorouracil (5-FU) as maintenance. We also conducted a case series including 12 patients who received FOLFIRINOX as induction chemotherapy for aPC or mPC followed by fluorouracil (5-FU) or FOLFIRI maintenance therapy. Median progression-free survival is 22.13 months which is higher than that reported in the literature, which ranges between 5 and 10.6 months. Although further conclusions cannot be drawn because of the small sample size, the results are promising and encourage further exploration of this topic in larger prospective trials.

Dual medial and anterior approach for excision of extraosseous synovial hip osteochondroma: a case report.

BACKGROUND: Osteochondromas are the most common benign bone tumors occurring near the end of long bones. In this case report, we demonstrate the successful treatment of a proximal femoral osteochondroma in a pediatric patient excised through a dual medial and anterior approach with no hip dislocation. CASE PRESENTATION: We present the case of a white Arab 14-year-old boy with chronic hip pain and inability to ambulate. He failed conservative treatment and was referred to us after X-rays revealed two osseous masses. He was diagnosed with an intra-articular hip osteochondroma confirmed on magnetic resonance imaging and computed tomography scan. He was treated surgically with excision using two incisions: Smith-Petersen approach and Ferguson approach. CONCLUSION: This case presents the successful resection of a symptomatic pediatric proximal femoral osteochondroma, using dual medial and anterior approaches without the need for hip dislocation. This was optimal for both the safety and accessibility of this unusual condition.

A phase II single arm study of Nivolumab with stereotactic Ablative radiation Therapy after induction chemotherapy in CHOlangiocarcinoma (NATCHO).

BACKGROUND: Intrahepatic cholangiocarcinoma (CCA) is amongst the most common primary liver tumors worldwide. CCA carries a bad prognosis prompting research to establish new treatment modalities other than surgery and the current chemotherapeutic regimens adopted. Hence, this trial explores a new therapeutic approach, to combine stereotactic body radiation therapy (SBRT) and immunotherapy (Nivolumab), and asses its clinical benefit and safety profile after induction chemotherapy in CCA. METHODOLOGY: This is a Phase II open-label, single-arm, multicenter study that investigates Nivolumab (PD-1 inhibitor) treatment at Day 1 followed by SBRT (30 Gy in 3 to 5 fractions) at Day 8, then monthly Nivolumab in 40 patients with non-resectable locally advanced, metastatic or recurrent intrahepatic or extrahepatic CCA. Eligible patients were those above 18 years of age with a pathologically and radiologically confirmed diagnosis of non-resectable locally advanced or metastatic or recurrent intrahepatic or extrahepatic CCA, following 4 cycles of cisplatin-based chemotherapy with an estimated life expectancy of more than 3 months, among other criteria. The primary endpoint is the progression free survival (PFS) rate at 8 months and disease control rate (DCR). The secondary endpoints are overall survival (OS), tumor response rate (TRR), duration of response, evaluation of biomarkers: CD3 + , CD4 + and CD8 + T cell infiltration, as well as any change in the PD-L1 expression through percutaneous core biopsy when compared with the baseline biopsy following 1 cycle of Nivolumab and SBRT. DISCUSSION: SRBT alone showed promising results in the literature by both inducing the immune system locally and having abscopal effects on distant metastases. Moreover, given the prevalence of PD-L1 in solid tumors, targeting it or its receptor has become the mainstay of novel immunotherapeutic drugs use. A combination of both has never been explored in the scope of CCA and that is the aim of this study. TRIAL REGISTRATION: ClinicalTrials.gov NCT04648319 , April 20, 2018.

Prevalence of Cosmetic Procedures among Lebanese Women.

Lebanese women have been portrayed as conceited and obsessed with physical appearance and its beautification through cosmetic procedures. Despite the pervasiveness of this notion, no formal studies have been conducted to assess the true prevalence of cosmetic procedures among Lebanese women. Additionally, no data exist to elucidate trends in popularity of cosmetic procedures over time. A cross-sectional study was conducted across Lebanese universities where surveys were distributed to women aged 18-31 years to estimate the prevalence of surgical, noninvasive, and dental cosmetic procedures in young Lebanese women. The collected survey data were analyzed using the Statistical Package for the Social Sciences (SPSS). In a sample of 877 women, 44% reported having undergone at least one cosmetic procedure in their lifetime. The most popular procedures performed were laser hair removal (32%), teeth whitening (14%), and rhinoplasty (9.3%). The obtained results revealed an increasing prevalence of cosmetic procedures, mirroring global trends. A variety of factors have contributed to the increasing popularity of cosmetic procedures, namely, higher availability, better affordability, and wider social acceptance over time.

Erector Spinae Blocks for Spine Surgery: Fact or Fad? Systematic Review of Randomized Controlled Trials.

BACKGROUND: Patients undergoing spine surgery may experience substantial postoperative pain. The aim of this systematic review is to examine the clinical efficacy of a newly introduced regional anesthetic block, the erector spinae plane block (ESPB), for adults undergoing posterior spine surgeries. METHODS: A formal systematic database search was conducted in PubMed, Ovid Medline, Embase, Cochrane library, and Google Scholar for randomized controlled trials comparing ESPB with control or placebo. RESULTS: Our systematic review demonstrates a reduction of postoperative pain and opioid consumption in patients who had ESPB compared with control groups for lumbar spine surgery. However, the effect obtained revealed only a short-term benefit. CONCLUSIONS: Current evidence is insufficient to support the widespread use of ESPB for spine surgery. More studies are warranted to confirm or refute its role in clinical practice.

Quality of life among men with spinal cord injury in Lebanon: A case control study.

BACKGROUND: Spinal cord injury (SCI) is a permanent disability which negatively affects individuals' health and particularly their quality of life. OBJECTIVE: To assess the quality of life (QoL) among Lebanese men with spinal cord injury and to compare it to a healthy control group. METHODS: A case control study was conducted. Fifty-one Lebanese patients with spinal cord injury and 51 age- sex-matched healthy persons were included in the study. RESULTS: Compared to healthy controls, the mean scores of eight domains of SF-36 were significantly lower in SCI group: physical functioning (PF) (26.5 vs 87; p value <0.0001), role limitations due to physical (RP) (57.8 vs 93.6; p value <0.0001), bodily pain (BP) (60.5 vs 90.7; p value, 0.0001), general health (GH) (49.5 vs 76.6; p value <0.0001), vitality (VT) (51.2 vs 71.3; p value <0.0001), social functioning (SF) (68.9 vs 91.2; p value <0.0001), role limitations due to emotional problems (RE) (71.2 vs 91.5; p value 0.003) and mental health (MH) (62.9 vs 79; p value <0.0001). Concerning PCS and MCS scores, SCI patients reported significantly lower scores than control group (p value <0.0001). CONCLUSION: Participants with SCI reported reduced QoL in comparison with normal individuals.

Validity and Reliability of the Arabic Patient Health Questionnaire-9 in Patients with Spinal Cord Injury in Lebanon.

BACKGROUND: Depression is a prevalent and disabling condition associated with spinal cord injury (SCI). Such associated negative factor warrants the use of valid and reliable psychological assessment tools among this group. One of the available assessment means is the Patient Health Questionnaire-9 (PHQ-9), a short screening measure that evaluates depression status. Our aim is to test the psychometric properties of the Arabic version of the PHQ-9 including validity and reliability among Lebanese individuals with SCI. METHODS: This is a cross-sectional study conducted between January and June 2018, including 51 participants with SCI. Questionnaire and assessment measures were administered to the subjects. The internal consistency, test-retest reliability, and the factor structure of the PHQ-9 were evaluated in addition to the convergent validity, which was established by comparing the scale's total score with the scores of the Hamilton Depression Rating Scale. RESULTS: Exploratory factor analysis revealed 3 factors accounting for 66.2% of the total variance. The scale demonstrated good internal consistency (Cronbach's alpha = 0.71) and test-retest reliability (Intraclass correlation coefficient = 0.88). Significant correlation was found between the PHQ-9 and the Hamilton Depression Rating Scale (r = 0.71) suggesting good convergent validity. CONCLUSIONS: Our findings suggest that the PHQ-9 has good psychometric properties and is a valid and reliable measure of depression among the Lebanese individuals with SCI.
