ER expression was assessed by immunohistochemistry. Associations between ER expression and clinicopathological variables were analyzed using …


Evaluation Of Peripheral Nerves In Patients With Acromegaly By Electrodiagnostic Study, Taiseer Saad Musa, Farqad Bader Hamdan, Abbas Mahdi Rahmah Jul 2026

Evaluation Of Peripheral Nerves In Patients With Acromegaly By Electrodiagnostic Study, Taiseer Saad Musa, Farqad Bader Hamdan, Abbas Mahdi Rahmah

Iraqi Postgraduate Medical Journal

Background: Acromegaly is a rare multisystem disorder caused by excess growth hormone (GH) and insulin-like growth factor 1 (IGF-1), typically from a pituitary somatotroph adenoma. Neurological complications, particularly peripheral neuropathies, are common but under-investigated.Objectives: To evaluate peripheral nerve involvement in Iraqi patients with acromegaly and assess the impact of IGF-1 levels, disease duration, adenoma size, and other clinical variables on nerve function.Methods: A cross-sectional study included 41 acromegalic patients (≥25 years) who underwent detailed neurophysiological testing. Patients were classified as metabolically controlled or uncontrolled based on IGF-1 levels.Results: IGF-1 and GH levels were significantly lower in the controlled group (p<0.001), while other clinical variables showed no significant differences. Neurophysiological findings revealed significantly reduced sensory and motor amplitudes, prolonged latencies, and slower conduction velocities in the uncontrolled group. IGF-1 levels correlated positively with sensory and motor latencies and negatively with conduction velocities and CMAP amplitudes. Larger adenoma size and presence of diabetes were also associated with worse nerve parameters. Deep X-ray therapy and surgical excision showed beneficial associations with median nerve conduction velocity.Conclusion: Peripheral nerve dysfunction, including carpal tunnel syndrome and polyneuropathy, is more severe in metabolically uncontrolled acromegaly. Macroadenomas and poor biochemical control are linked with worse neurophysiological outcomes.

Correlation Between Overthinking And Procrastination Behavior Among Nurses, Mona Hassan Abdelaal Jul 2026

Correlation Between Overthinking And Procrastination Behavior Among Nurses, Mona Hassan Abdelaal

Nursing

ABSTRACT Context: A key challenge in understanding internalizing psychological disorders is identifying the cognitive processes that sustain distress and disrupt effective functioning. Recurrent, hard-to-interrupt thinking patterns may interfere with individuals’ ability to initiate and complete intended tasks. Concurrently, individuals may persistently delay necessary actions despite recognizing their negative consequences, indicating a breakdown between intention and behavior. This pattern of delay appears to be associated with seeking short term emotional relief, reduced consideration of future outcomes, and avoidance of prolonged effort. While these issues have been studied independently, their overlapping mechanisms require further investigation. The potential role of repetitive cognitive processes …

May Measurement Month 2023: Results Of An Opportunistic Blood Pressure Screening Campaign In Kenya, Mzee Ngunga, Thomas Beaney, Gabriele Kerr, Bernard Samia, Lilian Mbau, Neil Poulter, Hellen Nguchu, Jeilan Mohamed, Elijah Ogola

Internal Medicine, East Africa

The May Measurement Month (MMM) is a global screening campaign launched in 2017 to raise awareness of raised blood pressure (BP). Kenya has participated in all previous MMM campaigns. Adults aged ≥18 years were recruited through convenience sampling in nine counties of Kenya. Three seated BP readings were taken on each participant, and a questionnaire collected information on demographics, lifestyle factors, and comorbidities. Hypertension was defined as a systolic BP ≥140mmHg or diastolic BP ≥90mmHg or being on BP-lowering medication. Controlled BP was defined as being on BP-lowering medication with a BP < 140/90mmHg. Multiple imputation was used to estimate missing BP readings. In total, 4,601 were screened, with a mean age of 41.7 years and 42.7% were female. Of all participants, 1,176 (25.6%) had hypertension, of whom 198 (16.8%) were aware, and 190 (16.2%) were on antihypertensive medication. Of those on antihypertensive medication, 65 (34.2%) had controlled BP, and of all participants with hypertension, 5.5% had controlled BP. The mean systolic and diastolic BPs of those on treatment was significantly higher than those without hypertension. Hypertensive disease in a previous pregnancy was associated with higher BP amongst female participants.

The MMM campaign in Kenya identified a substantial …

Health & Biomedical Sciences Faculty Publications

Charcot-Marie Tooth (CMT) disease is a clinically and genetically heterogeneous inherited peripheral neuropathy for which there is no treatment. CMT patients often present with weakness, fatigue, and muscle atrophy in the distal limbs. Improving function at the neuromuscular junction (NMJ) may improve function in some CMT patients. Using mouse models, we investigated eight CMT subtypes for NMJ phenotypes by morphology and functional deficits assessed by electromyography (EMG). We did not find NMJ abnormalities in mice with mutations in Gjb1Y/Δ2 (CMT1X), or Yars1E196K/E196K (diCMTC). Mice with mutations in Ighmbp2Y918S/Y918S (CMT2S) and Pla2g6M1J/M1J (Infantile Neuroaxonal Dystrophy) have neuromuscular …

Pangenome Analysis Of Proteus Mirabilis Reveals Lineage-Specific Antimicrobial Resistance Profiles And Discordant Genotype-Phenotype Correlations, Namrata Deka, Aimee L Brauer, Katherine Connerton, Blake M Hanson, Jennifer N Walker, Chelsie E Armbruster

Faculty, Staff and Student Publications

Urinary tract infections (UTIs) impose a large healthcare burden, with escalating antimicrobial resistance (AMR), and treatment failure. Proteus mirabilis is an undercharacterized and challenging UTI pathogen due to intrinsic resistance and biofilm formation. To understand P. mirabilis population genomics, we combined pangenome analysis, in silico AMR prediction, and phenotypic antimicrobial susceptibility testing (AST) across 1,027 P. mirabilis genomes derived from human urine specimens. This revealed a mosaic pangenome driven by extensive accessory genome plasticity. Multilocus sequence typing (MLST) identified 213 MLSTs, with only 7% having ≥10 genomes, highlighting strain diversity. AMR gene profiles were largely lineage-specific, with 25% of genomes …

Centre of Excellence in Women and Child Health

Particulate Matter (PM2.5) exposure contributes to the global disease burden, yet its monitoring remains sparse and uneven, with limited ground sensor infrastructure. Road-traffic proxy indicators can provide indirect estimates of PM2.5 where measurements are limited but require context-specific validation. We evaluated three PM2.5 road-traffic-related proxies: (i) population-Weighted Road Network Density (wRND), (ii) Euclidean (straight line) distance from highways (EH), and (iii) Euclidean distance from main roads (EM). We validated these proxies using high-resolution outdoor filtered PM2.5 personal exposure measurements collected over 1 year from 343 postpartum participants in The Gambia, Kenya, and Mozambique. Proxy-PM2.5 associations were assessed using Spearman correlation, …

Neonatal Admissions And Mortality: A Statistical Adjustment Approach Using Birthweight-Specific Curves To Address Bias Due To Underreporting In 65 Hospitals In Four African Countries, Lucas Malla, Siu Wong, Samuel Ngwala, Evelyn Zimba, Msandeni Chiume, Norman Lufesi, Kondwani Kawaza, Honorati Masanja, Josephine Shabani, William Macharia

Paediatrics and Child Health, East Africa

Background Underreporting of neonatal admissions and deaths – particularly among <  1000 g newborns – compromises the plausibility of in-patient neonatal mortality rate (iNMR) estimates. This limits progress tracking, since 2.3 million neonatal deaths occur annually, and 65 countries are projected to miss the Sustainable Development Goal (SDG) 3.2 target of fewer than 12 deaths per 1000 live births by 2030. Reliable iNMR estimates are essential for national and hospital-level monitoring. This study assessed birthweight-specific adjustment curves developed using simulated data, and extended the approach to routine data from 172,809 neonatal admissions across four African countries in the NEST360 network.

Methods Simulated data were generated using birthweight intervals of 500 g from 500 to 5000 g, with 1000 values per category representing 1000 hospitals. Admissions were drawn from a negative binomial distribution and mortality rates from a beta distribution based on published birthweight-specific iNMRs. Adjustment functions were developed using data from 500 hospitals without underreporting and tested on 500 with induced underreporting. This approach was then extended to real data from 65 NEST360 partnering hospitals. The adjustment functions were derived from 26 hospitals with plausible reporting (iNMR ≥ 700 per …

Unlocking The Potential Of Sub-Saharan Africa In Globalized Cancer Clinical Trials: A Perspective From The 2024 Aortic-Asco Stakeholder Meeting, Abiola Ibraheem, Adedayo Joseph, Miriam Mutebi, Mansoor Saleh, Sitna Mwanzi, Olusegun Alatise

General Surgery, East Africa

Sub-Saharan Africa (SSA) remains significantly underrepresented in global cancer clinical trials, despite having the largest population of individuals of African descent, an essential demographic for ensuring diversity in clinical research. This study, developed from the 2024 African Organization for Research and Training in Cancer (AORTIC)-ASCO stakeholder meeting, addresses the critical need to involve SSA in cancer trials to improve global trial diversity and patient outcomes. Although globalization of trials has shifted research sites to regions like Eastern Europe and Asia, < 1% occur in Africa. This report highlights emerging solutions such as regional alliances, decentralized trial models, capacity-building initiatives, and public-private partnerships. The role of AORTIC and its Clinical Trial Special Interest Group in advancing training, infrastructure development, and international collaboration is discussed, with notable clinical trial networks, such as HypoAfrica, ARETTA, African Research Group for Oncology, and regional consortia, illustrating growing momentum and capability. This study advocates for a coordinated strategy to integrate SSA into global trials, ensuring more inclusive, effective, and equitable cancer treatment outcomes.
