Multiple Sclerosis (MS) imposes significant burdens on patients, their families, and national healthcare systems particularly when there is a resource constraint. Proper prioritization and resource allocation are therefore essential for any effective disease management. Accordingly, we sought to assess the temporal profile of MS incidence over the past two decades in southeast Iran.

A longitudinal design was employed using data from the Iranian multiple sclerosis registry system from March 2001 to March 2019 (n=6034). Annual age-standardized incidence rates of MS (cases of clinically isolated syndrome were also included) were calculated and the trend of incidence from 2001 to 2018 was analyzed.

The age-adjusted incidence rate of MS raised from 1.72/100,000 in 2001 to 11.29/100,000 in 2018 (average of 18-year incidence rate was 6.30/100,000), indicating a notable rise in the incidence of MS (P-Value<0.001). However, the female to male ratio of 3.62 remained relatively stable during the study period.

Our study suggests that, in Fars province, the incidence of MS has been remarkably rising over the past two decades. We recommend further studies to better understand the determinants of this pattern. Implementing effective policies in lowering the burden of MS is another important step in this regard.

Two patients with clinical symptoms of cauda equina syndrome had positive serum MOG antibody tests, and spinal magnetic resonance imaging showed cauda equina enhancement. They were diagnosed with incomplete cauda equina syndrome associated with MOGAD. A few cases of lumbosacral radiculomyelitis associated with MOGAD have been reported; however, this is the first report of isolated lumbosacral radiculitis associated with MOGAD without transverse myelitis. The MOG antibody test should be considered for cauda equina syndrome without compressive lesions.

Widespread demyelination in the central nervous system can lead to progressive sensorimotor impairments following multiple sclerosis, with compromised postural stability during standing being a common consequence. As such, clinical strategies are needed to improve postural stability following multiple sclerosis. The objective of this study was therefore to investigate the effect of non-invasive transcutaneous spinal stimulation on postural stability during upright standing in individuals with multiple sclerosis.

Center of pressure displacement and electromyograms from the soleus and tibialis anterior were recorded in seven individuals with multiple sclerosis during standing without and with transcutaneous spinal stimulation. Center of pressure and muscle activity measures were calculated and compared between no stimulation and transcutaneous spinal stimulation conditions. The relationship between the center of pressure displacement and electromyograms was quantified using cross-correlation analysis.

For and explore the clinical value of transcutaneous spinal stimulation for individuals with multiple sclerosis.This paper links Heat Shock Protein Hsp90 as an evolutionary capacitator with the development of cancer. Hsp90 stabilises proteins associated with cancer in a number of ways. Canalisation allows for the accumulation of malignant mutations in the genome, and selection of beneficial phenotypes when cancer cells are stressed, allowing oncogenic development and progression. Hsp90 may allow for mutational ‘big bangs’ that can trigger primary malignant transformation. Hsp90 buffers catastrophic mutations in the oncogenome to prevent protein degradation and cellular apoptosis. Hsp90 was found to prevent the degradation of mutated p53, encouraging uncontrolled proliferation of cancer cells. Hsp90 buffering of mutations in response to cytotoxic therapy can lead to expression of beneficial phenotypes when Hsp90 is supressed and development of drug resistance. Trials with Hsp90 inhibitors have shown some success as an adjunctive therapy in preventing cancer progression, development of drug resistance, and even re-sensitisation to therapy after chemoresistance has developed.

Cancer of the cervix is the second most common cancer in women globally, and it is a major cause of morbidity and mortality among women in developing countries such as Nigeria. The study assessed the knowledge, attitude and perception on cervical cancer screening among women attending ante-natal clinic in Owerri West, south eastern Nigeria.

This cross-sectional study was conducted using a random sampling technique among 231 respondents attending ante-natal clinic in a cluster of 4 selected public primary healthcare centres. A structured questionnaire was used for data collection, and data obtained was analysed using a descriptive technique, while the chi-square test was used to test for the influence of age and education level on cervical cancer screening.

The result showed that there was a high level of awareness (68.8%) of cervical cancer screening. The majority of women (122 (52.8%)) received this information from friends. Although the majority of the participants had heard about the screening, few oening outcome. Age and level of education are significant factors of screening for cervical cancer. Educational programmes encouraging participation in cervical cancer screening should consider involving the use of close peers and friends to educate the women on the importance of screening program.

Awareness of cervical cancer is high, but the perception that it can be treated is quite low, along with fear of the screening outcome. Age and level of education are significant factors of screening for cervical cancer. Educational programmes encouraging participation in cervical cancer screening should consider involving the use of close peers and friends to educate the women on the importance of screening program.The coronavirus disease 2019 (COVID-19) pandemic has triggered a sudden global change in healthcare systems. Cancer patients have a higher risk of death from COVID-19 in comparison to patients without cancer. Many studies have stated that various factors, such as older age, frequent exposure to healthcare, and higher smoking rates are responsible for the complications of COVID-19. We hypothesize that side effects of chemotherapy, such as cellular senescence, could worsen COVID-19. Given this situation, in this review, we highlight the updated findings of research investigating the impact of cellular senescence on COVID-19 complications and explored potential therapeutic targets for eliminating senescent cells during the COVID-19 pandemic.This study aimed to characterize chemotherapy-induced transient increase and surge of CA 19-9 level to treatment response in patients with advanced pancreatic ductal adenocarcinoma (PDAC). A retrospective case series was performed of advanced PDAC patients treated with first-line chemotherapy at City of Hope Comprehensive Cancer Center from Jan 2017 to May 2020. CA 19-9 surge was defined as an increase of >20% from baseline followed by a >20% drop in one or more subsequent CA 19-9 levels compared to baseline. Out of 106 advanced PDAC patients, 38 were evaluable for CA 19-9 surge. Fourteen (51.9%) patients treated with FOLFIRINOX and 3 (27.3%) patients treated with nab-P + Gem chemotherapy demonstrated an early transient rise in CA 19-9 level. A CA 19-9 surge was documented in 9 (23.7%) patients, all with duration of surge lasting less then 16 weeks. Five out of 9 (55.6%) patients (4 FOLFIRINOX, 1 nab-P + Gem) with CA 19-9 surge demonstrated partial objective response rate on surveillance cross-sectional imaging. One patient (FOLFIRINOX) had stable disease, and 2 patients (1 FOLFIRINOX, 1 nab-P + Gem) were found to have disease progression after treatment interruption. The initial early rise of CA 19-9 levels during chemotherapy in patients with advanced PDAC may not indicate tumor progression. Rather, it may represent a chemotherapy-induced transient increase or surge phenomenon of the tumor marker in patients responding to treatment.Epithelial to mesenchymal transition (EMT) is a process associated with cancer malignancy and metastases. Cells undergoing EMT lose their epithelial phenotype and acquire mesenchymal phenotype. This process is accompanied by several molecular changes such as decrease of E-cadherin and increase of N-cadherin which is called the “cadherin swich”. MicroRNAs (miRNAs, miRs) are small non-coding RNAs having ability to regulate genes post-transcriptionally. Nowadays they are believed to take part in multiple physiological and pathological processes including cancer development. Comparison between TargetScan7 (www.targetscan.org) results for miR-200b and metanalysis of genes involved in EMT showed that miR-200b has a potential binding site in 60 genes that are involved in EMT (the majority of them were associated with mesenchymal phenotype). Our review summarizes literature findings contributing to experimentally proven interactions between miR-200b and genes involved in EMT process including cell receptors, signaling pathways, cell cycle or cell adhesion. The results of those interactions indicate that miR-200b may have an inhibitory impact on EMT or even in selected cases is able to restore epithelial phenotype.The aim of this study was to reveal the mechanism underlying the toxicity of TNT (trinitrotoluene), RDX (cyclotrimethylene trinitroamine), and HMX (cyclotetramethylene tetranitramine) explosives pollution in plants. Here, the effects of exposure to these three explosives were examined on chlorophyll fluorescence, antioxidant enzyme activity, and the metabolite spectrum in alfalfa (Medicago sativa) plants. The degradation rates for TNT, RDX, and HMX by alfalfa were 26.8%, 20.4%, and 18.4%, respectively, under hydroponic conditions. TNT caused damage to the microstructure of the plant roots and inhibited photosynthesis, whereas RDX and HMX induced only minor changes. Exposure to any of the three explosives caused disturbances in the oxidase system. Non-targeted metabolomics identified a total of 6185 metabolites. TNT exposure induced the appearance of 609 differentially expressed metabolites (189 upregulated, 420 downregulated), RDX exposure induced 197 differentially expressed metabolites (155 upregulated and 42 downregulated), and HMX induced 234 differentially expressed metabolites (132 upregulated and 102 downregulated). Of these differentially expressed metabolites, lipids and lipid-like molecules were the main metabolites induced by explosives poisoning. TNT mainly caused significant changes in the alanine, aspartate, and glutamate metabolism metabolic pathways, RDX mainly caused disorders in the arginine biosynthesis metabolic pathway, and HMX disrupted the oxidative phosphorylation metabolic pathway. Taken together, the results show that exposure to TNT, RDX, and HMX leads to imbalances in plant photosynthetic characteristics and antioxidant enzyme systems, changes the basic metabolism of plants, and has significant ecotoxicity effects.
