    We would like to report two cases of preretinal haemorrhage from two different aetiology courses of bleeding being treated with intravitreal ranibizumab and its outcome. Our first case was a 39-year-old man with a diagnosis of severe aplastic anaemia that presented with bilateral premacular haemorrhages in both eyes. His right eye vision was 6/45 and it was counting finger in the left eye. He was treated with intravitreal ranibizumab once to the right eye and twice to the left eye. Right eye showed complete resolution of premacular haemorrhage and minimal residual premacular haemorrhage in the left eye at 3 months after initial presentation. Our second case was a 32-year-old healthy teacher that presented with preretinal haemorrhage at superotemporal region extending to macular area in left eye secondary to valsalva retinopathy. Her left vision was counting finger. She was treated with single intravitreal ranibizumab to the left eye. There was significant reduction of premacular haemorrhage and her left eye vision improved to 6/6 at 10 weeks after injection. Both cases had favourable outcome with intravitreal ranibizumab and can be considered as nonsurgical treatment option in treating premacular haemorrhage.

    PURPOSE: To update resource-stratified, evidence-based recommendations on secondary prevention of cervical cancer globally.

    METHODS: American Society of Clinical Oncology convened a multidisciplinary, multinational Expert Panel to produce recommendations reflecting four resource-tiered settings. A review of existing guidelines, formal consensus-based process, and modified ADAPTE process to adapt existing guidelines was conducted. Other experts participated in formal consensus.

    RESULTS: This guideline update reflects changes in evidence since the previous update. Five existing guidelines were identified and reviewed, and adapted recommendations form the evidence base. Cost-effectiveness analyses provided indirect evidence to inform consensus, which resulted in ≥ 75% agreement.

    RECOMMENDATIONS: Human papillomavirus (HPV) DNA testing is recommended in all resource settings; visual inspection with acetic acid may be used in basic settings. Recommended age ranges and frequencies vary by the following setting: maximal: age 25-65 years, every 5 years; enhanced: age 30-65 years, if two consecutive negative tests at 5-year intervals, then every 10 years; limited: age 30-49 years, every 10 years; basic: age 30-49 years, one to three times per lifetime. For basic settings, visual assessment is used to determine treatment eligibility; in other settings, genotyping with cytology or cytology alone is used to determine treatment. For basic settings, treatment is recommended if abnormal triage results are obtained; in other settings, abnormal triage results followed by colposcopy is recommended. For basic settings, treatment options are thermal ablation or loop electrosurgical excision procedure; for other settings, loop electrosurgical excision procedure or ablation is recommended; with a 12-month follow-up in all settings. Women who are HIV-positive should be screened with HPV testing after diagnosis, twice as many times per lifetime as the general population. Screening is recommended at 6 weeks postpartum in basic settings; in other settings, screening is recommended at 6 months. In basic settings without mass screening, infrastructure for HPV testing, diagnosis, and treatment should be developed.Additional information is available at www.asco.org/resource-stratified-guidelines.

    Breast cancer (BC) is among the most frequent malignancies women face around the globe. Nanotherapeutics are constantly evolving to overcome the limitations of conventional diagnostic and therapeutic approaches. Nanotechnology-based nanocarriers have a higher entrapment efficiency, low cytotoxicity, greater stability and improved half-life than conventional therapy. Nano-drug delivery systems have improved pharmacokinetics and pharmacodynamics parameters because of nanomeric size. Currently, various nano-formulations are in preclinical and clinical settings for breast cancer, like polymeric nanoparticles, micelles, nanobodies, magnetic nanoparticles, liposomes, niosomes, gold-nanoparticles, dendrimers and carbon-nanotubes. This review highlights the recent advancement in developing nano-drug delivery systems for BC treatment. This review will open the gateway to researchers to understand the current approaches to developing nano-formulation and improving problems associated with conventional therapy.

    A previous study has shown that synthetic antimicrobial peptides (AMPs) derived from Anabas testudineus (ATMP1) could in-vitro inhibit the progression of breast cancer cell lines. In this study, we are interested in studying altered versions of previous synthetic AMPs to gain some insight into the peptides functions. The AMPs were altered and subjected to bioinformatics prediction using four databases (ADP3, CAMP-R3, AMPfun, and ANTICP) to select the highest anticancer activity. The bioinformatics in silico analysis led to the selection of two AMPs, which are ATMP5 (THPPTTTTTTTTTTTYTAAPATTT) and ATMP6 (THPPTTTTTTTTTTTTTAAPARTT). The in silico analysis predicted that ATMP5 and ATMP6 have anticancer activity and lead to cell death. The ATMP5 and ATMP6 were submitted to deep learning databases (ToxIBTL and ToxinPred2) to predict the toxicity of the peptides and to (AllerTOP & AllergenFP) check the allergenicity. The results of databases indicated that AMPs are non-toxic to normal human cells and allergic to human immunoglobulin. The bioinformatics findings led to select the highest active peptide ATMP5, which was synthesised and applied for in-vitro experiments using cytotoxicity assay MTT Assay, apoptosis detection using the Annexin V FTIC-A assay, and gene expression using Apoptosis PCR Array to evaluate the AMP's anticancer activity. The antimicrobial activity is approved by the disc diffusion method. The in-vitro experiments analysis showed that ATMP5 had the activity to inhibit the growth of the breast cancer cell line (MDA-MB-231) after 48 h and managed to arrest the cell cycle of the MDA-MB-231, apoptosis induction, and overexpression of the p53 by interaction with the related apoptotic genes. This research opened up new opportunities for developing potential and selective anticancer agents relying on antimicrobial peptide properties.

    Postoperative pseudomeningocele usually has a benign course. We report a rare presentation of postoperative acute neurological deficit caused by compressive thoracic pseudomeningocele. This patient had posterior spinal fusion and decompression surgery for thoracic ossification of posterior longitudinal ligament and ligamentum flavum. Intraoperative incidental durotomy was covered with hydrogel dural sealant. She developed acute neurological deterioration 1 week after index surgery. Emergency decompression surgery was performed. One year after the surgery, she showed good neurological recovery.

    Simulium (Gomphostilbia) okinawense Takaoka and S. (G.) tokarense Takaoka, both from the Nansei Islands, Japan, were morphologically reexamined and genetically analysed by using the COI gene sequences. The female, male, pupa and mature larva of the two species are redescribed. Morphological reexamination shows that both species are more similar to species in the S. asakoae species-group than to those in the S. ceylonicum species-group, by having a medium-long female sensory vesicle, yellow tuft hairs (S. (G.) okinawense) or yellow tuft hairs mixed with a few to several dark hairs (S. (G.) tokarense) at the base of the radial vein in the female and male, and medium-long larval postgenal cleft. However, the body of the male ventral plate (viewed ventrally) is parallel-sided (S. (G.) okinawense) or parallelsided or slightly narrowed (S. (G.) tokarense) and not emarginated basally, differing from those of most species in the S. asakoae species-group. Our genetic analysis shows that S. (G.) tokarense is in the S. asakoae species-group, and S. (G.) okinawense formed a separate sister clade with other members of the S. asakoae species-group with high bootstrap support. From the results of morphological and genetic analysis combined, S. (G.) okinawense and S. (G.) tokarense are transferred from the S. ceylonicum species-group to the S. asakoae species-group.

    Continuous Spinal Anaesthesia (CSA) technique has all the advantages of single-shot spinal anaesthesia with the added benefit of prolonging the duration of anaesthesia. CSA has been used as a primary method of anaesthesia as an alternative to general anaesthesia in high-risk and elderly patients for various elective and emergency surgical procedures involving the abdomen, lower limbs, and vascular surgeries. CSA has also been used in some obstetrics units. Despite its advantages, CSA technique remains underutilised because it is surrounded with myths, mysteries, and controversies concerning neurological, other morbidities and minor technical difficulties. This article includes a description of CSA technique compared to other contemporary central neuraxial blocks. It also discusses the perioperative applications of CSA for different surgical and obstetrics procedures, advantages, disadvantages, complications, problems, and pointers on how to perform the technique safely.

    BACKGROUND: Hyperemesis gravidarum (HG) affects about 2% of pregnancies and is at the severe end of the spectrum of nausea and vomiting of pregnancy. HG causes severe maternal distress and results in adverse pregnancy outcomes long after the condition may have dissipated. Although dietary advice is a common tool in management, trial evidence to base the advice on is lacking.

    METHODS: A randomized trial was conducted in a university hospital from May 2019 to December 2020. 128 women at their discharge following hospitalization for HG were randomized: 64 to watermelon and 64 to control arm. Women were randomized to consume watermelon and to heed the advice leaflet or to heed the dietary advice leaflet alone. A personal weighing scale and a weighing protocol were provided to all participants to take home. Primary outcomes were bodyweight change at the end of week 1 and week 2 compared to hospital discharge.

    RESULTS: Weight change (kg) at end of week 1, median[interquartile range] -0.05[-0.775 to + 0.50] vs. -0.5[-1.4 to + 0.1] P = 0.014 and to the end of week 2, + 0.25[-0.65 to + 0.975] vs. -0.5[-1.3 to + 0.2] P = 0.001 for watermelon and control arms respectively. After two weeks, HG symptoms assessed by PUQE-24 (Pregnancy-Unique Quantification of Emesis and Nausea over 24 h), appetite assessed by SNAQ (Simplified Nutritional Appetite Questionnaire), wellbeing and satisfaction with allocated intervention NRS (0-10 numerical rating scale) scores, and recommendation of allocated intervention to a friend rate were all significantly better in the watermelon arm. However, rehospitalization for HG and antiemetic usage were not significantly different.

    CONCLUSION: Adding watermelon to the diet after hospital discharge for HG improves bodyweight, HG symptoms, appetite, wellbeing and satisfaction.

    Hirschsprung's disease (HD) is one of the most well-known gastrointestinal motility disorders. Diagnosis and management of other lesser-known motility disorders are often challenging and tedious. We describe a teenager who was severely constipated from birth and needed intensive care admissions for life-threatening enterocolitis. She also had concomitant anal stenosis. Several rectal biopsies were unable to yield a conclusive diagnosis. Surgical level of resection had to be identified based on the motility of the bowel as determined by transit studies using oral ingestion of a milk feed labelled with Technetium-99m colloid. After completion of all operative stages, histopathological examination of the excised specimens concluded that she had short-segment HD associated with reduced interstitial cells of Cajal in the large bowel. She is currently continent, evacuating voluntarily approximately four times a day and is relieved of all her symptoms.

    While artificial intelligence (AI) offers promising solutions in healthcare, it also poses a number of threats to human health and well-being via social, political, economic and security-related determinants of health. We describe three such main ways misused narrow AI serves as a threat to human health: through increasing opportunities for control and manipulation of people; enhancing and dehumanising lethal weapon capacity and by rendering human labour increasingly obsolescent. We then examine self-improving 'artificial general intelligence' (AGI) and how this could pose an existential threat to humanity itself. Finally, we discuss the critical need for effective regulation, including the prohibition of certain types and applications of AI, and echo calls for a moratorium on the development of self-improving AGI. We ask the medical and public health community to engage in evidence-based advocacy for safe AI, rooted in the precautionary principle.

    BACKGROUND: Despite the high prevalence, few studies have examined pornography consumption among emerging adults in Malaysia. The current study examined the attitudes, motivations, and behaviours related to pornography consumption and their association with sexual health.

    METHODS: Using a cross-sectional survey that was conducted online, a convenience sample of 319 Malaysians aged 18-30years (M =23.05, s.d.=2.55) reported their attitudes and behaviours related to pornography consumption, including the degree of problematic consumption, and completed measures of sexual health. These included sexual satisfaction, awareness of sexual feelings, sexual self-reflection, sexual assertiveness, embarrassment during partnered sex, and genital image. To capture pornography genre preferences, participants also reported the keywords that they typically use to search for pornography. These open-ended responses were thematically coded.

    RESULTS: Between 60 and 70% of participants reported positive attitudes toward pornography and 81.2% (N =259) reported lifetime intentional exposure to pornography. Gender differences were present in pornography consumption attitudes, motivations, preferences, and behaviours. Problematic pornography consumption, and not consumption frequency, was associated with poorer sexual satisfaction. Among women and not men, more frequent consumption was associated with more sexual self-reflection and positive feelings about their genitals. Sexual embarrassment was higher among women who consume pornography more problematically and among men who consumed pornography more frequently.

    CONCLUSIONS: Pornography consumption attitudes and behaviours appear rather universal. However, the benefits of pornography consumption frequency and disadvantages associated with problematic consumption appear to be more relevant for women's than men's sexual health, specifically sexual self-reflection, genital image, and sexual embarrassment.

    Infantile haemangioma represents a congenital vascular anomaly commonly observed in the head and neck region. Such an occurrence over the postcricoid region, however, is rather unusual. Herein, the authors report a case of a synchronous postcricoid haemangioma in a 7-week-old newborn diagnosed with severe laryngomalacia. In addition to the floppy redundant arytenoid mucosa, flexible laryngoscopy revealed a lobulated bluish mass at the postcricoid. The lesion was hyperintense on T1-weighted sequence and was enhanced with contrast, supporting the diagnosis of a haemangioma. She underwent surgical excision of the haemangioma with intralesional steroid injection. Surveillance at 6-month postoperation did not show disease recurrence.

    Activin A is a two-subunit protein belonging to the transforming growth factor β superfamily. First discovered almost three decades ago, it has since been implicated in diverse physiological roles, ranging from wound repair to reproduction. After 30 years of research, altered activin A levels are now understood to be associated with the development of various diseases, making activin A a potential therapeutic target. In pregnancy, the placenta and fetal membranes are major producers of activin A, with significantly enhanced serum concentrations now recognised as a contributor to numerous gestational disorders. Evidence now suggests that circulating levels of activin A may be clinically relevant in the early detection of pregnancy complications, including miscarriage and preeclampsia. This review aims to summarise our current understanding of activin A as a potential diagnostic marker in common pregnancy pathologies.

    Cross-border marriages have been found to be associated with domestic violence due to the migration experiences of the couples concerned and the stress experienced before, during, and after migration, despite local and international legislation on domestic violence. A systematic review using the PRISMA Statement was conducted to examine the relationship between domestic violence and cross-border marriages among cross-border wives from Asian countries. Six databases-Taylor & Francis Online, Wiley Online, Scopus, Web of Science, Sage Journals, and Springer Online library, were used in the research which found 179 articles for eligibility and 58 articles were finally used in the review. To be included, studies must have addressed domestic violence and cross-border marriage among Asians, report qualitative, quantitative, or mixed methods, addressed the RQs, been published in polished English between 2010 and 2020 and published in a reputable journal with high impact factor. The systematic review found that immigration status, citizenship, culture, language barrier, diversity/intersectionality, age, and economic dependence are the risk factors for domestic violence, which leads effects such as divorce or separation, racism, loneliness, loss of identity & inheritance, stigma, abandonment, and discrimination. Yet these cross-border wives resorted to NGOs, social & religious groups, and traditional beliefs as coping strategies. The review suggests that legislations on domestic violence should be amended to include a definition of the rights of immigrant women, and the plight of cross-border wives, which should be protected. It is also imperative to propose favorable laws and policies regarding immigration status and citizenship for these cross-border couples.

    INTRODUCTION: Empathy is the ability to put oneself in another's emotional space and experience what they feel. Either due to lack of experience or mundaness of practice, a state of empathy can become premised, and individuals become indifferent or detached. We aimed to explore the level of empathy among doctors at different levels of practice, age, gender, academics, non-academics and discipline.

    MATERIALS AND METHODS: This was a cross-sectional, observational study on empathy among doctors practicing in the private, public hospital sector and faculty at a medical university in Negeri Sembilan, Malaysia that utilised convenience sampling for data collection. The Toronto Empathy Questionnaire (TEQ) a validated tool was used to measure empathy.

    RESULTS: The questionnaire was completed by 127 doctors, 52% (n= 66) were males and 48% (n=61) females. There was no significant difference in empathy between male (M=46.44; SD=6.01) and female (M=45.05, SD=5.69) doctors; t (123) = 1.326, p=0.187. Pearson correlation coefficient was computed to assess the linear relationship between age and empathy and revealed no correlation between the two variables: r (125) =0.15, p=0.099. Medical-based doctors (M= 47.47, SD=5.98) demonstrated more empathy than surgicalbased (M=44.32, SD=5.41); t (123) =-3.09, p=0.002. Those already specialised in their fields (M=47.38, SD=4.57) had more empathy than those who had not (M= 44.36, SD=6.52); t (123) =-2.96, p = 0.004. Doctors in the university (M=47.97, SD=4.31) tended to have more empathy than those in the public hospitals (M= 44.63, SD=6.27); t (117) =-2.91, p=0.004. Academicians had more empathy than non-academicians but there was no difference between those who were in clinical practice and not.

    CONCLUSION: Our findings indicate that medical-based doctors demonstrate more empathy than surgical-based doctors, and there appeared to be no correlation between age and empathy. However, clinical experience and growth within the specialty seem to improve empathy. Doctors teaching in the university setting demonstrated more empathy than those practicing in the hospital setting. Inclusion of empathy-related sessions in the undergraduate and post-graduate curriculum could bridge the gap in empathy noted with age, discipline, and experience in practice. Further research on empathy among doctors using a wider population in Malaysia and a TEQ questionnaire validated to the Asian population would provide better insight regarding this area of medical practice. Future research on outcomes of inclusion of programmes targeted at improving empathy to create awareness during practice would support patient satisfaction and safety.

    Hypertension is the leading risk factor for cardiovascular disease and premature death among women globally. However, there is a fundamental lack of knowledge regarding the sex-specific pathophysiology of the condition. In addition, risk factors for hypertension and cardiovascular disease unique to women or female sex are insufficiently acknowledged in clinical guidelines. This review summarizes the existing evidence on women and female-specific risk factors and clinical management of hypertension, to identify critical knowledge gaps relevant to research, clinical practice, and women's heart health awareness. Female-specific risk factors relate not only to reproduction, such as the association of gynecological conditions, adverse pregnancy outcomes or menopause with hypertension, but also to the specific roles of women in society and science, such as gender differences in received medical care and the underrepresentation of women in both the science workforce and as participants in research, which contribute to the limited evidence-based, gender- or sex-specific recommendations. A key point is that the development of hypertension starts in young, premenopausal women, often in association with disorders of reproductive organs, and therefore needs to be managed early in life to prevent future cardiovascular disease. Considering the lower blood pressure levels at which cardiovascular disease occurs, thresholds for diagnosis and treatment of hypertension may need to be lower for women.

    Deep inspiration breath-hold radiotherapy (DIBH-RT) reduces cardiac dose by over 50%. However, poor breath-hold reproducibility could result in target miss which compromises the treatment success. This study aimed to benchmark the accuracy of a Time-of-Flight (ToF) imaging system for monitoring breath-hold during DIBH-RT. The accuracy of an Argos P330 3D ToF camera (Bluetechnix, Austria) was evaluated for patient setup verification and intra-fraction monitoring among 13 DIBH-RT left breast cancer patients. The ToF imaging was performed simultaneously with in-room cone beam computed tomography (CBCT) and electronic portal imaging device (EPID) imaging systems during patient setup and treatment delivery, respectively. Patient surface depths (PSD) during setup were extracted from the ToF and the CBCT images during free breathing and DIBH using MATLAB (MathWorks, Natick, MA) and the chest surface displacement were compared. The mean difference ± standard deviation, correlation coefficient, and limit of agreement between the CBCT and ToF were 2.88 ± 5.89 mm, 0.92, and - 7.36, 1.60 mm, respectively. The breath-hold stability and reproducibility were estimated using the central lung depth extracted from the EPID images during treatment and compared with the PSD from the ToF. The average correlation between ToF and EPID was - 0.84. The average intra-field reproducibility for all the fields was within 2.70 mm. The average intra-fraction reproducibility and stability were 3.74 mm, and 0.80 mm, respectively. The study demonstrated the feasibility of using ToF camera for monitoring breath-hold during DIBH-RT and shows good breath-hold reproducibility and stability during the treatment delivery.

    Little is known about whether withdrawal-like symptoms manifest when regular pornography users attempt to abstain from pornography. The present study used a randomized controlled design to examine whether (1) negative abstinence effects that may be potentially reflective of withdrawal-related symptoms manifest when a non-clinical sample of regular pornography users attempt to abstain from pornography for a 7-day period and (2) these negative abstinence effects would only manifest (or manifest more strongly) for those with higher levels of problematic pornography use (PPU). A total of 176 undergraduate students (64.2% female) who were regular pornography users (defined as having used pornography ≥ three times a week in the past 4 weeks) were randomly assigned to an abstinence group (instructed to attempt abstinence from pornography for 7 days, n = 86) or a control group (free to watch pornography as usual, n = 90). Participants completed measures of craving, positive and negative affect, and withdrawal symptoms at baseline and each night of the 7-day period. Contrary to the confirmatory hypotheses, there were no significant main effects of group (abstinence vs. control) or group × PPU interaction effects on any of the outcome measures, controlling for baseline scores. These findings indicate that no evidence of withdrawal-related symptoms was found for abstaining participants, and this was not dependent on level of PPU. However, exploratory analyses showed a significant three-way interaction (group × PPU × past 4-week frequency of pornography use [FPU]) on craving, where an abstinence effect on craving was found at high levels of PPU only once past 4-week FPU reached the threshold of daily use. While these exploratory findings should be interpreted with caution, they suggest that abstinence effects could potentially manifest when there is a combination of high PPU and high FPU-a hypothesis that warrants investigation in future prospective abstinence studies.

    The body of evidence supports the negative impact of increased sperm DNA fragmentation (SDF) on natural fertility as well as assisted reproduction conditions. High SDF has been correlated with low pregnancy and delivery rates following intrauterine insemination. Also, high SDF is accused of reducing the rates of fertilization, implantation, pregnancy, and live birth following in-vitro fertilization (IVF). Despite no impact of high SDF on fertilization or pregnancy rates following intracytoplasmic sperm injection (ICSI), it has been correlated with poor embryo quality and a higher risk of miscarriage. Several methods have been introduced to help select sperm with the best DNA quality to be used in assisted reproductive technology procedures. These include magnetic-activated cell sorting, intracytoplasmic morphologically selected sperm injection, physiologic ICSI, and microfluidic sperm sorters, among others. This article aimed to discuss the impact of high SDF in infertile men on the reproductive outcome of couples undergoing IVF/ICSI. Additionally, this review highlights the principles, advantages, and limitations of different techniques that are currently used for the selection of sperm with intact DNA to be utilized for ICSI.
