EFFECT OF GLYCEMIC CONTROL (HBA1C) ON TESTOSTERONE LEVELS AND HEMATOLOGICAL PARAMETERS, AND DISTRIBUTION PATTERN OF BLOOD GROUPS AMONG TYPE 2 DIABETIC PATIENTS IN MUKALLA CITY

2026-07-07T16:18:51+00:00

Poor glycemic control in Type 2 Diabetes Mellitus (T2DM) leads to systemic complications, including hormonal imbalances and hematological alterations. This study aimed to evaluate the effect of poor glycemic control (HbA1c) on testosterone levels, complete blood count (CBC), and blood groups among T2DM patients in Mukalla city. A cross-sectional analysis study was conducted (March-July 2021) involving 60 participants; 40 T2DM patients (24 males, 16 females) and 20 healthy controls (13 males, 7 females), with an age range of 30–70 years. Fasting blood glucose, HbA1c, CBC, blood typing, and testosterone levels were measured in both groups. Statistical analysis was used to assess differences and correlations between the variables. The results showed a significant increase in fasting blood glucose and HbA1c (8.08 ± 1.80%) in patients compared to healthy individuals (p=0.001). Hormonally, a significant decrease in testosterone was observed in males with T2DM (4.61 ± 1.79 ng/mL), while no significant effect was observed in females compared to the healthy group (7.32 ± 0.84 ng/mL). Hematologically, hemoglobin levels were significantly decreased in patients (p=0.008), with a significant increase in lymphocytes (40.14%) and a decrease in neutrophils (48.9%). Blood Group O was the most prevalent (47.5%). Correlation analysis revealed a strong and statistically significant inverse relationship between HbA1c levels and testosterone in males (r = -0.436, p = 0.001), and an inverse relationship between HbA1c and hemoglobin levels (r = -0.299, p = 0.02). The study concludes that poor glycemic control is closely associated with decreased testosterone levels in males, as well as with adverse changes in hematological parameters, including decreased hemoglobin concentration and altered white blood cell differential. Therefore, routine testosterone screening is recommended for male diabetic patients.

CLINICO EPIDEMIOLOGICAL PROFILE OF SKIN & ORAL CANCERS AMONG PATIENTS ATTENDING NATIONAL CANCER CENTER IN ADEN /YEMEN: A RETROSPECTIVE STUDY

2026-07-01T09:12:08+00:00

Cancer is a leading causes of death globally, with skin and oral cancer representing significant public health challenges. Epidemiological data from Yemen regarding these malignancies are limited. This study aims to provide data on the incidence, patterns, and clinic-epidemiological characteristics of malignant skin and oral tumors diagnosed by biopsy at National Cancer Center in Aden /Yemen, over five years (2020 to 2024). A retrospectively analytical study was con-ducted reviewing all histopathologically confirmed cases of skin and oral cancer (Excluding pharyngeal cancer) registered at archive of National Cancer Center, Aden, from January 2020 to December 2024. Demographic data, histopathological types and lesions sites were collected and analyzed using SPSS version 15. Chi-square tests were used to examine associations between categorical variables, with P < 0.05 considered statistically significant. Of 7961 total cancer cases registered during the study period, 156 (1.9 %) were skin and oral cancers. Skin cancer constituted 43 cases (0.5% of total cancers), while oral cancer comprised 113 cases (1.4%). Of total 156, males predominated (93 cases, 59.6%) with a male –to female ratio of 1.5:1. The most affected age group was 41-60 years (70 cases, 44.9%) followed by 61-80 years (47 cases, 30.1%). Mean age was 56.4±16.3 years (range: 19-96 years). Squamous cell carcinoma (SCC) was the most common malignancy (127 cases, 81.4%), including one SCC in situ (0.6%), (106 cases, 67.9%) in oral cavity, followed by basal cell carcinoma (BCC) (9 cases, 5.7%), malignant melanoma (MM) (7 cases, 4.5%), lymphoma (4 cases, 2.5%) and kaposi sarcoma (3 cases, 1.9%). The head and neck region, including oral cavity, was the most site (137 cases, 87.1%). Among oral cancers, tongue was the predominant location (72 case, 46.2%). Annual case numbers ranged from 44 (28.2%) in 2020 to 21 (13.5 %) in 2024. This study provides epidemiological data on skin and oral cancers in southern, Yemen. SCC predominates, with an apparent increase in SCC compared to previous regional studies. The findings highlight the need for further research into etiological factors and implement implementation of awareness programs, preventive measures and treatment strategies.

SERUM FERRITIN, LDH, AND CRP AS POTENTIAL PROGNOSTIC BIOMARKERS IN BREAST CANCER: ASSOCIATION WITH TUMOR GRADE, STAGE, AND RECEPTOR STATUS

2026-07-01T09:22:00+00:00

Inflammatory biomarkers such as serum ferritin, lactate dehydrogenase (LDH), and C-reactive protein (CRP) have been implicated in cancer progression and prognosis. This study aimed to evaluate their association with clinicopathological characteristics in breast cancer patients from Yemen. A cross-sectional analysis of 150 breast cancer patients (60 newly diagnosed, 90 managed) was conducted. Serum levels of ferritin, LDH, and CRP were measured and correlated with tumor size, grade, lymph node status, hormone receptor status, and human epidermal growth factor receptor 2 (HER2) expression. Serum ferritin, LDH, and CRP levels were significantly elevated in patients with higher tumor grade (Grade III), advanced tumor stage (T3/T4), lymph node involvement (N2/N3), and metastatic disease (p<0.05). Ferritin levels were higher in HER2-positive and progesterone receptor-positive tumors. CRP was elevated in estrogen receptor-negative and progesterone receptor-negative subgroups in managed cases. All three markers showed a stepwise increase with advancing tumor burden. Managed patients had significantly lower levels of all markers compared to newly diagnosed patients, indicating treatment response. Serum ferritin, LDH, and CRP are significantly associated with aggressive tumor features in breast cancer. These inexpensive and readily available biomarkers may serve as useful prognostic tools, particularly in resource-limited settings like Yemen, to stratify risk and monitor treatment response.

HYDROLOGICAL AND HYDRAULIC MODELING FOR FLOOD RISK ASSESSMENT IN WADI YESHBUM- SHABWA GOVERNORATE, IN YEMEN

2026-07-01T09:33:59+00:00

Flash floods in arid regions pose severe threats to life and infrastructure, yet quantitative hydrological data are frequently absent. This study presents the first hydrologic model for the ungauged Wadi Yeshbum basin (337.48 km²) in Shabwah Governorate, Yemen, using the HEC-HMS model within a GIS framework. Morphometric parameters were derived from a 30 m SRTM DEM, revealing a steep average slope (10.5%), a well-developed drainage network (drainage density 1.8 km/km²), and a short time of concentration (4.38 h). The spatially distributed curve number (CN) was computed from FAO soil data and ESA CCI land cover, yielding a weighted average of 83, indicative of high runoff potential. Historical daily rainfall (1994–2024) from CHIRPS was used to fit the Gumbel distribution; 24-h design storms for return periods of 20, 50, and 100 years were estimated as 34.3, 40.5, and 44.9 mm, respectively. The SCS unit hydrograph method was applied to transform excess rainfall into direct runoff. Simulated peak discharges were 733.8, 867.5, and 963.7 m³/s with corresponding runoff volumes of 8.88, 11.72, and 13.03 million m³. Because no observed streamflow data were available for calibration, a generalized likelihood uncertainty estimation (GLUE) based on 500 Monte Carlo runs gave a 95% confidence interval for the 100-year peak discharge of 712.7–1177.7 m³/s. Sensitivity analysis revealed that peak discharge is highly sensitive to CN (coefficient 3–4) and moderately sensitive to the time of concentration (coefficient ~0.7–1.0). The results demonstrate that the basin exhibits a rapid, flashy hydrological response and that a large fraction (77–86%) of extreme rainfall becomes direct runoff. The modeling framework is transferable to other data-scarce arid basins and provides quantitative baseline information for flood mitigation planning in Yemen, though all results should be considered uncalibrated screening-level estimates.

EVALUATING THE EFFICACY OF SURGICAL INTERVENTIONS IN ENHANCING MOTOR FUNCTION IN CHILDREN WITH CEREBRAL PALSY, ADEN YEMEN

2026-07-01T09:41:00+00:00

Single event multilevel surgery refers to the correction of all orthopaedic deformities in one session. To evaluate the outcomes of Single Event Multi-Level Surgery in children with spastic cerebral palsy. We retrospectively studied all 38 children with cerebral palsy and gait deviations who underwent single-event multilevel surgery between January 2016 and December 2022 in Al-Naqib Hospital, in Aden. Data were presented as mean values with the standard deviation. The chi-square test was used to test for significance. We used SPSS ver. 22 for statistical analysis. Statistical significance was defined as a P-value of < 0.05. Thirty-eight children patients suffering of spastic-type cerebral palsy underwent surgical interventions in enhancing motor function. Single event multilevel surgery procedures performed. The age of patients at surgery ranged from 4–17 years with a mean age of 10.8±4.2 years. Gender distribution was (73.7%) males to (26.3%) females. The affected lower limb represented as predominant in (89.5%) patients. Jump gait was predominant in (79.0%) children and the hemiplegic gait was in (10.5%). Postoperatively at final follow up, the gait pattern was normal in (26.3%) children and near normal in (73.7%) children. Preoperatively, the majority of children were classified at higher levels of motor impairment with (63.2%) children patients categorized as Gross Motor Function Classification System Level II. At the final follow-up, significant improvements were observed in gross motor function. The number of children classified as Gross Motor Function Classification System Level I increased markedly to (65.8%). The number of children in level II decreased to (23.7%). Two children had a superficial wound infection postoperatively. Recurrent hamstring contracted were found in (7.9%) children and at the final follow up, knee pain was found in (21.1%) children. The results of single event multilevel surgery are considered satisfactory with minimal complications.

POST-MARKETING QUALITY ASSESSMENT OF GENERIC ROSUVASTATIN TABLETS IN ADEN-YEMEN

2026-07-01T10:01:55+00:00

The increasing availability of generic Rosuvastatin (ROS) tablets necessitates rigorous post-marketing quality evaluation, particularly in regions with limited regulatory oversight, such as Yemen. This study aimed to assess the pharmaceutical quality and in vitro performance of commercially available ROS (20 mg) tablet brands in the Aden market. Five ROS brands were evaluated using validated high-performance liquid chromatography (HPLC) and pharmacopeial quality control tests in accordance with USP/BP guidelines. Parameters assessed included weight variation, hardness, friability, disintegration time, and dissolution. Dissolution testing was conducted at pH 6.6 following FDA recommendations due to the acid instability of ROS. The HPLC method demonstrated excellent linearity (R² = 0.9993), with assay values ranging from 92.01% to 108.45%, complying with pharmacopeial limits. All brands met requirements for weight uniformity, friability, and disintegration. Although TAB.3 and TAB.4 exhibited higher hardness values (20.22 and 18.3 kg/cm²), this did not adversely affect their performance. Dissolution studies showed that all brands released more than 80% of the labeled drug within 30 minutes, with most exceeding 85%, indicating rapid dissolution. TAB 1 showed a lower mean dissolution of 75.99% at the 30-minute time point. All evaluated ROS brands demonstrated acceptable pharmaceutical quality and in vitro performance, supporting their potential interchangeability. However, variability in dissolution behavior among certain brands highlights the importance of continuous post-marketing surveillance to ensure consistent therapeutic efficacy in the Yemeni pharmaceutical market.

EVALUATION OF RADIATION HAZARDS RESULTING FROM NATURAL RADIOACTIVITY ACTIVITIES AROUND AL-WAHDA CEMENT FACTORY IN ABYAN GOVERNORATE, YEMEN

2026-07-01T10:18:04+00:00

The primary objective of this study is to measure the level of radioactivity in the soil around Al-Wahda Cement Factory in Abyan Governorate, Yemen, and to evaluate the radiological hazards of radionuclides. Twenty soil samples were collected from various locations in the Abyan Governorate (Izl Bates, Al-Hosn, Al-Rawa, Helmeh) to determine the activity concentrations of background radionuclides such as (Radium-226, Thorium-232, and Potassium-40). The activity concentrations were measured using gamma-ray spectrometry with a high-purity germanium detector (HPGe). The results show the activity concentration of ²²⁶Ra ranged from 15.5 to 27.40 with an average value of 21.92Bqkg^-1. The activity concentrations of ²³²Th ranged from 18.80 to 55.40 with an average value of 33.60Bqkg^-1. Activity concentrations of ⁴⁰K ranged from 248.70 to 660.40 with an average value of 572.40Bqkg^-1. The values of the average activity concentrations for ²²⁶Ra and ²³²Th are 21.92Bqkg^-1 and 32.1Bqkg^-1, respectively, these values agree with these radionuclides present in soil worldwide (1.3-52.8) Bqkg^-1 and (0.9-90.3) Bqkg^-1 have been reported by UNSCEAR, 2008, respectively. The average activity of ⁴⁰K concentrations in soil is 572.4Bqkg^-1 it is higher than the world average (412Bqkg^-1) reported by UNSCEAR 2008.Radiological hazard indices were evaluated based on radionuclide activity concentrations. The absorbed dose rates ranged from 34.38 to 66.82 nGy/h, with annual effective doses remaining below internationally recommended limits, indicating no significant radiological risk to cement factory workers or the surrounding environment.

LOGARITHMIC COEFFICIENTS AND HANKEL DETERMINANT FOR A NEW SUBCLASS OF CLOSE-TO-STAR FUNCTIONS ASSOCIATED WITH THE SINE FUNCTION

2026-07-01T11:00:04+00:00

In this paper, we investigate the logarithmic coefficients for a new subclass of close-to-star functions associated with the sine function. We derive explicit formulas for the first six logarithmic coefficients γ₁ through γ₆ for functions in this class. We obtain upper bounds for the Hankel coefficients, Hankel determinants H_2,1 (f), H_2,2 (f), H_3,1 (f)and H_4,1 (f) associated with the class CST₀ (sin z). In addition, we derive sharp estimates for the Hankel determinant for the logarithmic coefficients H_2,1(F_f /2) and H_2,2 (F_f /2) within the same class.

REACTIVE BURSITIS SECONDARY TO DISTAL FEMORAL OSTEOCHONDROMA: MRI FEATURES, DIAGNOSTIC CHALLENGES, AND SURGICAL CORRELATION: A CASE REPORT

2026-07-01T11:14:41+00:00

Osteochondroma is the most common benign bone tumor, typically presenting in children and adolescents. It is characterized by a bony outgrowth with a cartilage cap that usually arises in the metaphyseal regions of long bones. These lesions are often asymptomatic but may be complicated by fractures, deformities, neurovascular compression, or bursitis. Imaging, particularly MRI, plays a vital role in identifying these features, and distinguishing benign changes from malignant transformation can occur in adulthood, although metastasis is rare. We report an 18-year-old male presenting with progressive swelling and dull pain in the left distal thigh. Radiographs demonstrated a pedunculated bony lesion originating from the distal femoral metaphysis, with cortical and medullary continuity, consistent with an osteochondroma. MRI revealed a cartilage-capped lesion with an adjacent fluid-filled collection, indicative of secondary reactive bursitis. The lesion was surgically excised, and histopathology confirmed a benign osteochondroma with associated bursal tissue. The postoperative course was uneventful without complications. This case highlights the importance of advanced imaging—especially MRI—for accurately diagnosing osteochondroma and its secondary complications such as reactive bursitis, aiding surgical planning, and distinguishing benign pathology from potential malignant change. MRI also supports postoperative assessment for complete excision and recurrence.
