Introduction: Glioblastoma multiforme (GBM) is one of the deadliest cranial tumors occurring in adults. Various biomarkers have been tested for their significance in diagnosis, prognosis, and treatment of GBM. Some well-studied markers in GBM are Isocitrate dehydrogenase 1 (IDH1), Murine double minute 2 (MDM2), Epidermal Growth Factor Receptor (EGFR), and p53. The aim of this study was to investigate the protein expression of these markers in GBM patients of Pakistan. Methods: A total of 102 surgically resected formalin-fixed paraffin-embedded specimens from patients diagnosed and treated at Aga Khan University Hospital were included in this study. Immunohistochemistry (IHC) for IDH1, MDM2, EGFR, and p53 was performed using Dako EnVision System and respective monoclonal antibodies. Survival analysis was performed to check association of markers protein expression with prognosis in GBM patients. Results: There were 73 males and 29 females in this study, with a median age of 49 years at the time diagnosis. Overexpression of molecular markers was as follows: 52% for EGFR, 26% for p53, 72% for IDH1, and 83% for MDM2. We did observe that EGFR was significantly associated with increased age of our patients and with worse survival. Age > 40 years was a predictor for worse prognosis as well. Conclusion: EGFR overexpression and advanced age were worse prognostic indicators.

Introduction This study translated and validated the Urdu version of the European Organization for Research and Treatment of Cancer Quality of Life (QoL) Questionnaire (EORTC QLQ-C30) and Brain Module (QLQ-BN20) amongst patients with primary brain tumors (PBT) in Pakistan, and assessed the correlation of QoL with resilience, depression, and anxiety. Methods Translation of the EORTC QLQ-C30 and QLQ-BN20 was performed as per EORTC guidelines. A survey comprising of Urdu translations of EORTC QLQ-C30, QLQ-BN20, Wagnild and Young Resilience Scale (RS-14) and Hospital Anxiety and Depression Scale was administered to patients with PBT at a tertiary care hospital in Pakistan. Reliability (via Cronbach alpha), content validity index (CVI) scores, construct validity, and inter-scale correlations were assessed. Results Our sample consisted of 250 patients with PBT, most commonly glioma (46.8%) and meningioma (21.2%). All patients were able to understand the Urdu translations. The Cronbach alphas for the QLQ-C30 and the QLQ-BN20 were 0.860 and 0.880, respectively. The CVI scores for clarity and relevance were high for both the EORTC QLQ-C30 (0.98 and 0.96, respectively) and the QLQ-BN20 tool (0.81 and 0.95, respectively). The global QoL domain (EORTC QLQ-C30) showed significant positive correlations with resilience (r = 0.422), and significant negative correlations with depression (r =  − 0.541) and anxiety (r =  − 0.502). Strong inter-scale correlations were observed between physical functioning and insomnia (r =  − 0.690) and role functioning and insomnia (r =  − 0.641). Conclusion Our study confirms the Urdu versions of the EORTC QLQ-C30 and QLQ-BN20 as valid clinical tools for the measurement of QoL in primary brain tumors patients within the cultural and socioeconomic context of Pakistan. Plain language summary Quality of life (QoL) is an important facet of well-being for patients with primary brain tumors (PBTs), as these individuals face significant distress during the course of their illness and treatment. It is important to have valid and reliable tools to accurately measure the QoL of patients with PBTs. The EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) and its brain tumor-specific module EORTC QLQ-BN20 (EORTC QLQ-Brain Neoplasms 20) are exactly that. However, the use of the EORTC QLQ-C30 and QLQ-BN20 is limited in Pakistan, where the national language is Urdu, and the majority of patients are of low socioeconomic backgrounds. Since no Urdu translations of the EORTC QLQ-C30 and QLQ-BN20 exist, we aimed to translate and validate these tools to enable their applicability in Pakistan. The Urdu versions of the EORTC QLQ-C30 and QLQ-BN20 demonstrated good validity amongst patients with PBTs. Thus, our study confirms the EORTC QLQ-C30 and QLQ-BN20 as valuable clinical tools for the measurement of QoL in primary brain tumors patients within the linguistic, cultural and socioeconomic context of Pakistan.

Multicentric and multifocal gliomas are rare and mainly described in high-grade gliomas, however, they have rarely been reported with LGG in about 2–10 % of all cases. This study aims to identify the reported multicentric low-grade gliomas (mLGGs) in literature and review their pathologies, management, and outcomes. A systematic search using a pre-defined search strategy was conducted across three databases (PubMed, Cochrane Library, and Scopus). Following the PRISMA guidelines, relevant articles were selected. The data including demographic details, clinical presentations, lesion locations, pathology, neurosurgical interventions, extent of resection, adjuvant therapies, and survival outcomes were reported. We identified 36 patients across 17 studies. Presenting symptoms varied, with seizures (27.7 %) and headaches (22.2 %) being the most common. Typical imaging features involve hypo- to isotense signals on T1-weighted images and hyperintensity on T2-weighted images, with MR spectroscopy aiding in differentiation. Histological consistency across tumor sites was observed in 29 cases, with some variability in a few. Survival was 66.6 % among patients, and initial reports in the 1960s indicated high mortality due to intracranial pressure shifts. Adjuvant therapies included chemotherapy (14 patients) and radiotherapy (9 patients), though many cases lacked complete therapy data. Although chemotherapy and radiotherapy lacked a significant impact on progression-free survival, early, extensive resection remains advocated, with a mean progression-free survival of 30.14 months. Most of the current evidence surrounding mLGG consists of case reports with few retrospective case series. Early, extensive resection appears to be the most effective approach for managing mLGG, while adjuvant therapies have limited impact on progression-free survival, highlighting the need for more comprehensive molecular profiling to guide treatment. Further research into standardized protocols for adjuvant therapies and long-term outcomes is essential to optimize survival and improve management of unresectable or recurrent cases. •Multicentric Low-grade gliomas show high long-term survival: 87 % (children) and 85 % (adults).•Maximum safe resection is the preferred treatment, with re-resection as needed.•Postoperative chemo/radiotherapy did not significantly affect progression-free survival.•Molecular markers may improve prognosis assessment for multicentric LGGs.

Objective There are reports of a potential rise in a teaching hospital’s morbidity and mortality rates during the trainee turnover period, i.e., with the induction of new residents and house staffs, and the changeover of clinical teams. The published literature displays mixed reports on this topic with lack of reproducible observations. The current study was conducted to explore existence of any such phenomenon (January effect) in Pakistan. Methods This retrospective cohort study was conducted at Aga Khan University Hospital, Karachi, Pakistan. Five-year (2013–2018) record of all the patients in all age groups related to these outcomes was retrieved and recorded in specifically designed questionnaire. Different outcome measures were used as indicators of patient care and change in these outcomes at the time of new induction was related to possible January effect. Results During the five-year study period, more than 1100 new trainees were inducted into the post graduate medical education program (average of 237 per year) with more than 22,000 inpatient admissions (average of 45,469 per year). Some patterns were observed in frequencies of surgical site infections, medication errors, sentinel events, patient complaints, and adverse drug reactions. However, these were not consistently reproducible and could not be directly attributed to the trainee turnover. All other indicators did not show any pattern and were considered inconclusive. No effect of overlap was observed. Conclusions Inconsistency in the patient care quality indicators do not favor existence of January effect in our study. Further research is recommended to establish our results.

Introduction With a growing interest in simulation-based training to develop clinical proficiency, bootcamps have been utilized for imparting basic skills to medical trainees. While considerable research on the topic exists in high income countries, no such neurosurgical teaching standards have been employed in Low- and Middle-Income Countries. Methods We conducted a cross-sectional study to explore the effectiveness of first low-cost, multi-center regional neurosurgery bootcamp in South Asia. Twenty-two participants attended the bootcamp and practiced 12 hands-on skills over the course of 2 days. Burr-holes and craniotomies were done on 3D printed skulls. Lumbar drain insertion was practiced on a purpose-built lumbar puncture mannequin. For laminectomy, we used an in-house designed simulation. The modified Objective Structured Assessment of Technical Skills tool was utilized for skills Assessment. Feedback from faculty and residents was collected via a standard 5-point Likert scale. Results Only one participant (4.55%) had previously attended a neurosurgical skills workshop. Comparison of outcomes on 1 st and 3 rd attempts of cranial and spinal skills showed a significant improvement in all 14 domains assessed ( p <0.05). Positive feedback was received ranging from 3.9 up to 4.8 on a 5-point Likert scale. Overall cost per participant culminated to $145, significantly lower than previously reported data. Conclusion Our findings report the effectiveness of sustainable, low-cost training models which can be easily reproduced elsewhere. These indigenously designed simulators can be modified for variable difficulty level and serve as an effective educational strategy in improving learners’ skills, knowledge and confidence.

Objective Despite quality of life (QoL) being recognized as an important outcome in neuro-oncology, there is a lack of research from Pakistan where sociocultural differences may influence QoL. This study aimed to measure the QoL in patients with primary brain tumors (PBTs) and assess its association with mental health outcomes and social support. Results Our study included a total of 250 patients, with a median age of 42 years (range 33–54 years). The commonest brain tumors were glioma (46.8%) and meningioma (21.2). The mean global QoL of the sample was 75.73 ± 14.9. The majority of patients had high social support (97.6%) and were not depressed (90%) or anxious (91.6%). On multivariable linear regression, global QoL was inversely associated with no or low income (beta coefficients: −8.75 to −11.84), having hypertension (−5.53), currently using a urine catheter (−13.55), having low social support (−28.16) suffering from mild (−15.31) or symptomatic (−23.84) depression, or mild anxiety (−13.22).

ObjectiveThe prevalence of depression among patients with primary brain tumour ranges from 15% to 40% globally. Several individual and clinical factors contribute to the development of depression. However, their association with depression in Pakistani setting has not yet been assessed. Thus, we aim to study the factors associated with depression among adult patients with primary brain tumour at a tertiary care hospital in Karachi, Pakistan.Study designA prospective cross-sectional study.SettingThis study was conducted at a tertiary care hospital of Karachi, Pakistan.ParticipantsThis study included 132 patients with confirmed diagnosis of primary brain tumour (initially diagnosed on MRI of the brain with contrast and later confirmed on histology of surgical specimen) in various stages of treatment.Primary outcomeThe primary outcome of this study was to assess depression and its associated factors among adult patients with primary brain tumour. Depression was assessed using a validated screening tool Patient Health Questionnaire-9 (PHQ-9). Scores of 10–27 on PHQ-9 were indicative of screen positive for depressive symptoms. A set of the structured pre-tested questions was used to evaluate patient-related, tumor-related and treatment-related factors.ResultsFifty-one (39%, CI: 33.33–46.94) patients in our study screened positive for depressive symptoms on PHQ-9. There was a significant association between depressive symptoms and Karnofsky Performance Scores (KPS) (prevalence ratio: 3.25 and CI: 1.87–5.62) after controlling covariates. Propensity scores predicted a positive association between KPS (functional status) and unemployment, treatment stage, and tumour recurrence. Tumor-related and treatment-related factors including tumour grade, location, type and hemispheric lateralisation were found insignificant.ConclusionDepression is common in patients with primary brain tumour. Impaired functional status has a direct impact on depression in these patients. Incorporating the psychosocial domain earlier in the course of treatment needs to be considered for better neuro-oncology management of patients with primary brain tumour.

BackgroundIntra-operative seizures (IOS) can occur during awake craniotomies (AC) for brain tumors. They can potentially result in an increased risk of morbidity; however, literature is scarce on IOS, its risk factors, and predictors. This study aims to ascertain the frequency of IOS in patients undergoing AC and determine possible IOS predictors.MethodsIn this retrospective study, we reviewed the records of all patients who underwent AC for tumor resection at a single university hospital between January 2016 and December 2020. IOS was defined as any seizure, including partial or generalized, experienced by any patient at any time from the beginning of the procedure till the end of surgery.ResultsTwo hundred patients underwent AC during the study period. Seven (3.5%) patients experienced IOS. Compared to the non-seizure group, no significant correlation existed with any demographic variable. No significant difference was seen between the initial complaints presented by the two groups. In addition, the post-operative course of the seizure group did not significantly differ from the non-seizure group. Due to the low frequency of IOS in our cohort, an extensive analysis to determine predictors could not be performed.ConclusionIn this study, we observed a low frequency of IOS (3.5%) during AC. The possible predictors and risk factors must be further investigated in large cohorts; to help limit the consequences of this possible intraoperative complication.

Introduction Brain tumor resection under awake settings may cause significant psychological stress, which may lead to perioperative anxiety and depression. We conducted a prospective study to compare postoperative depression in patients undergoing awake craniotomy (AC) for tumor resection and compare it with patients undergoing tumor resection under general anesthesia (GA). Methods We conducted a prospective study at a tertiary care hospital. Non-probability consecutive sampling was performed, and patients with a preoperative diagnosis of depression or with any other medical comorbidities that could precipitate depression were excluded. Two separate questionnaires, the Patient Health Questionnaire-9 (PHQ-9) Scale and the Karnofsky Performance Score (KPS), were used to screen depression and assess functional status, respectively. Results Ninety-six patients met the inclusion criteria and were included in the study. Out of these, 37 (38.1%) had undergone awake craniotomy and 59 (60.8%) had undergone conventional craniotomy (CC) (under general anesthesia) for brain tumor resection. To standardize our method, we ensured that the demographic variables, including mean age, gender, educational status, marital status, and socioeconomic conditions, were comparable between both groups. Postoperative functional status fared better in patients who underwent awake craniotomy (p = 0.03). The total number of patients suffering from postoperative clinical depression, according to the PHQ-9 Scale, was 41 (42.7%), of which 12 (12.5%) were in the awake craniotomy group and 29 (30.2%) were in the conventional craniotomy group. The median PHQ-9 Scale score in the awake craniotomy group was 6 (range: 3-10), which was less than the median score in the conventional craniotomy group, which was 9 (range: 4-12). This difference, however, was not statistically significant (p = 0.06). Conclusion Resection of brain tumors under awake conditions is not likely associated with any additional incidence of postoperative depression when compared with resection of tumors under general anesthesia.

IntroductionSurgical site infections (SSIs) are among the the most common postoperative complications, despite being highly preventable. Multiple studies have explored the incidence and risk factors of SSIs globally. However, nationally representative data capable of informing evidence-based guidelines remain limited in Pakistan. Hence, the aim of this study is to identify the incidence and risk factors of developing SSIs following surgery and to explore existing SSI prevention practices in Pakistan.Methods and analysisThis study is a multicentre, prospective cohort study across various sites in Pakistan. All consecutive adult patients undergoing inpatient elective surgery in a 1 month patient recruitment window from one or more of the nine eligible subspecialties will be included in the study. Patients with preoperative infections, emergency surgeries or intraoperative mortality are to be excluded. The following surgical subspecialties are included: breast surgery, cardiac surgery, colorectal surgery, cranial surgery, general surgery, obstetrics and gynaecology, orthopaedics surgery, spine surgery and vascular surgery. Each mini-team of up to three collaborators can select one of the nine subspecialties and a 1 month patient recruitment window from 20 September 2022 to 31 March 2023. Multiple mini-teams from the same sites can recruit patients across the same subspecialty in distinct patient recruitment windows. Additionally, multiple mini-teams from the same sites can recruit patients across different subspecialties in the same or distinct patient recruitment windows. The primary outcome is 30 day SSIs. Secondary outcomes include 30 day antibiotic-resistant SSIs, organ-space infections, other healthcare associated infections, reinterventions and all-cause mortality.Ethics and disseminationApproval was received by the Aga Khan University (AKU) Ethics Review Committee (ERC) and the National Bioethics Committee (NBC) Pakistan. The results from this study will be disseminated by the steering committee in journal publications, conference presentations and on other academic platforms. Evidence-based guidelines that result from these data will be disseminated to all surgical care providers in Pakistan through national networks.
