    Despite the advancement in cancer diagnosis and treatment, colorectal cancer remains the leading cause of cancer-related death worldwide. Given the high recurrence rate of colorectal cancer even after surgical resection, chemotherapy has been clinically used to improve the treatment outcomes of colorectal cancer. However, chemotherapy is well-known for its toxic side effects. Thus, phytochemicals have been widely studied in recent years as preventive and therapeutic agents for colorectal cancer owing to their relatively low toxicity. Moreover, combinatorial uses of phytochemicals with other natural compounds or with drugs may amplify the positive outcomes of colorectal cancer prevention and treatment by intervening in multiple signaling pathways and targets. This review summarized the combinatorial use of several well-studied groups of phytochemicals, that is, isothiocyanates, quinones, carotenoids, and alkaloids, in the prevention and treatment of colorectal cancer, and suggested it as a potential approach to improve the anticancer efficacy of single compounds and minimize the toxic side effects associated with conventional drugs. Notably, we generalized the in vitro, in vivo, and clinical experiments-based molecular mechanisms whereby the selected phytochemicals in combination with other compounds exerted anti-colorectal cancer effects by inhibiting cancer cell proliferation, cell apoptosis, cell invasion, and tumor growth. Overall, this review provides a reference and new perspective to propel further advancements in research and development of preventative and therapeutic strategies for colorectal cancer.

    BACKGROUND: Stressful life events greatly increase the risk of depression, which affects about 22% of older persons in northeast Malaysia. But how emotional distress manifests itself in reaction to these stressful events differs from person to person. Therefore, this study aims to delve into the nuances of emotional expression among older adults with depression symptoms in northeast Malaysia, alongside their help-seeking behaviours and utilisation of professional support.

    METHODS: Using a qualitative interpretative phenomenological approach, we conducted in-depth face-to-face interviews with participants, guided by Kleinman's explanatory model of illness. Nineteen older adults who screened positive for depression were included in the research.

    RESULTS: None of the participants explicitly acknowledged experiencing depression. However, they articulated their distress through three primary themes: 'Life is miserable,' 'Depression is a sign of weakness,' and 'Belief in pre-determination.' Remarkably, despite screening positive for depression, participants demonstrated a lack of awareness regarding available professional mental health services. Moreover, they expressed a reluctance to seek such services, citing reasons related to stigma and misconceptions. The predominant themes that emerged concerning help-seeking behaviours were 'Self-efficacy,' 'Social support,' and 'Formal assistance from non-mental healthcare professionals.'

    CONCLUSION: The expression of emotion among older adults is restricted by socio-cultural influences. Thus, there is a need to improve mental health literacy among older adults in Malaysia, and their preferred source of support such as religious leaders and non-mental healthcare physicians.

    Cancer is one of the deadliest health menaces humans have ever witnessed. It is a leading cause of human mortality. Today, it remains a main leading cause of death globally primarily due to lifestyle changes and population ageing. A total of ~12.7 million cancer cases and 7.6 million cancer deaths were reported in 2008. In developing countries, cancer accounted for 56% of cases and 64% of deaths. Tamoxifen is the most reputable and recommended specific oestrogen receptor modulator drug used for the treatment of breast cancer. In the past decade, algae have demonstrated remarkable potency for advanced life applications. They can remain a focus of interest in the coming decades because they are one of the most diverse organisms in the entire ecosystem with immense bio nutritional benefits. Algae and their extracts play a pivotal role in the pharmaceutical industry as bioactive compounds and new drugs and nutraceutical industry as probiotics and antioxidants. However, a broad range of the health benefits of these organisms remains to be explored. The present review highlights the applications and co-application of microalgal crude extracts with tamoxifen for breast cancer immunotherapy. Given that recent studies have suggested that tamoxifen is an essential and primary treatment for breast cancer, the present review focused on the identification of a new treatment approach involving the co-application of tamoxifen and microalgal extracts to provide promising anticancer activity with few side effects on normal cells. The present review includes a general background and blueprint for the use of microalgal extracts as potential and affordable treatments or adjuncts for breast cancer management.

    Despite the implementation of various initiatives, dengue remains a significant public health concern in Malaysia. Given that dengue has no specific treatment, dengue prediction remains a useful early warning mechanism for timely and effective deployment of public health preventative measures. This study aims to develop a comprehensive approach for forecasting dengue cases in Selangor, Malaysia by incorporating climate variables. An ensemble of Multiple Linear Regression (MLR) model, Long Short-Term Memory (LSTM), and Susceptible-Infected mosquito vectors, Susceptible-Infected-Recovered human hosts (SI-SIR) model were used to establish a relation between climate variables (temperature, humidity, precipitation) and mosquito biting rate. Dengue incidence subject to climate variability can then be projected by SI-SIR model using the forecasted mosquito biting rate. The proposed approach outperformed three alternative approaches and expanded the temporal horizon of dengue prediction for Selangor with the ability to forecast approximately 60 weeks ahead with a Mean Absolute Percentage Error (MAPE) of 13.97 for the chosen prediction window before the implementation of the Movement Control Order (MCO) in Malaysia. Extended validation across subsequent periods also indicates relatively satisfactory forecasting performance (with MAPE ranging from 13.12 to 17.09). This research contributed to the field by introducing a novel framework for the prediction of dengue cases over an extended temporal range.

    Propolis is a sticky substance produced by stingless bees for construction and defence of their hive. It has notable anti-inflammatory, antioxidant, antibacterial, antifungal, anti-hyperglycemic, and wound healing effects. The present review summarised and examined the phytochemical properties, mode of action and current research prospects of Malaysian propolis. A database search using Google Scholar, Web of Science and ScienceDirect generated 780 references; 30 relevant articles were included in the present review, of which 23 were in vitro studies and 7 were in vivo or animal studies. Propolis demonstrated antioxidant, antibacterial, antifungal, anti-inflammatory and anti-hyperglycemic properties, indicating potential as a wound healing agent. Despite favourable findings, due to the scarcity of studies in the literature, more in-depth research and clinical validation on the synergistic effects, efficacy and optimum dosage of propolis are needed.

    OBJECTIVE: This study aimed to adapt, validate, and evaluate the feasibility of a mindful exercise program (Mindful Standing Yoga combined with Baduanjin) for older patients with primary osteoporosis.

    METHODS: The study was conducted in 3 stages. Stage 1 involved a qualitative focus group discussion with 6 experts to gather perspectives on modifying the exercise program. Stage 2 used a Delphi approach with another 6 experts to validate the program. In Stage 3, a feasibility study was conducted with 20 eligible patients (out of 23 initially enrolled) at a traditional Chinese medicine hospital, using a single-group pre- and posttest design. The strenuousness of the adapted exercise was assessed through heart rate (HR) and rating of perceived exertion (RPE). Its effects were measured using the Global Pain Scale (GPS), the Five Facets Mindfulness Questionnaire-Short Form (FFMQ-SF), the Tampa Kinesiophobia-11 Scale, and the Timed Up and Go test. Patient satisfaction and feedback were also collected.

    RESULTS: The modified program, consisting of 9 movements and taking 30 min to complete, was validated by experts as suitable, safe, and effective for practice. HR and RPE measurements confirmed it as a low-intensity exercise and not strenuous for the study population. The program significantly improved back pain and mindfulness in the feasibility study, with most participants expressing satisfaction with the protocol.

    CONCLUSION: Experts and participants affirmed that the program was appropriate and satisfactory for older patients with primary osteoporosis, particularly those with back pain. Further high-quality randomized controlled trials are needed to validate its effectiveness.

    The burgeoning crises of antimicrobial resistance and plastic pollution are converging in healthcare settings, presenting a complex challenge to global health. This study investigates the microbial populations in healthcare waste to understand the extent of antimicrobial resistance and the potential for plastic degradation by bacteria. Our metagenomic analysis, using both amplicon and shallow shotgun sequencing, provided a comprehensive view of the taxonomic diversity and functional capacity of the microbial consortia. The viable bacteria in healthcare waste samples were analyzed employing full-length 16S rRNA sequencing, revealing a diverse bacterial community dominated by Firmicutes and Proteobacteria phyla. Notably, Proteus mirabilis VFC3/3 and Pseudomonas sp. VFA2/3 were detected, while Stenotrophomonas maltophilia VFV3/2 surfaced as the predominant species, holding implications for the spread of hospital-acquired infections and antimicrobial resistance. Antibiotic susceptibility testing identified multidrug-resistant strains conferring antimicrobial genes, including the broad-spectrum antibiotic carbapenem, underscoring the critical need for improved waste management and infection control measures. Remarkably, we found genes linked to the breakdown of plastic that encoded for enzymes of the esterase, depolymerase, and oxidoreductase classes. This suggests that specific bacteria found in medical waste may be able to reduce the amount of plastic pollution that comes from biological and medical waste. The information is helpful in formulating strategies to counter the combined problems of environmental pollution and antibiotic resistance. This study emphasises the importance of monitoring microbial communities in hospital waste in order to influence waste management procedures and public health policy. The findings highlight the need for a multidisciplinary approach to mitigate the risks associated with antimicrobial resistance and plastic waste, especially in hospital settings where they intersect most acutely.

    The presence of human immunodeficiency virus (HIV) infection increases the risk of acquiring human papillomavirus (HPV) infection and developing HPV-related adversities. We aimed to estimate the cost-effectiveness of HPV vaccination for women living with HIV in a Chinese setting. A decision-analysis Markov model was developed to estimate the cost-effectiveness of 36 HPV vaccination strategies for women living with HIV aged 18-45 years, from the healthcare system perspective. With the status quo, not vaccinating women living with HIV would lead to 51.99% (51,985/100,000) HIV-related deaths; 35.10% (35,098/100,000) would develop genital warts, 0.36% (355/100,000) develop cervical cancer, and among which 63.66% (226/355) die from cervical cancer over their lifetime (1,601,457 person-years). With a willingness to pay (WTP) threshold of three times gross domestic product (GDP), Gardasil 4 vaccination for all women living with HIV aged 18-45 years was the most cost-effective strategy (ICER = US $32,766/QALY gained). This strategy would reduce genital warts by 35.52% (12,467/35,098), cervical cancers by 12.96% (46/355), and cervical cancer deaths by 12.39% (28/226) over the lifetime of the cohort. If the future domestic Cecolin 9 vaccine is priced at 60% of Gardasil 9, vaccinating all women living with HIV aged 18-45 years with Cecolin 9 would be the most cost-effective strategy (ICER = US $30,493/QALY gained). Improving adherence to antiretroviral therapy for HIV may substantially improve the cost-effectiveness of both Gardasil 4 and Cecolin 9 vaccination.

    Metastatic breast cancer (MBC) is an advanced-stage breast cancer associated with more than 90 % of cancer-related deaths. Immunosuppressive properties of tolerogenic dendritic cells (tolDCs) in tumour immune microenvironment (TIME) may be a risk factor for the rapid progression to MBC. However, the exact connections between the two are unknown. The aim of the current study is to uncover gene signatures and key pathways associated with MBC and tolDCs via an integrated bioinformatics approach. Gene expression profiles of MBC and tolDCs were retrieved from Gene Expression Omnibus (GEO) to identify common differentially expressed genes (DEGs). From DGE analysis, 529 upregulated common DEGs and 367 downregulated common DEGs had been identified. In enrichment analysis, common DEGs enriched in GO terms of defense response to virus and KEGG pathway of transcriptional misregulation in cancer were reported to be significantly associated with MBC and tolDCs. From the constructed PPI networks, 23 hub genes were identified, although only 5 genes were significant; 3 upregulated (ISG15, OAS2 and RSAD2) and 2 downregulated (eEF2 and PPARG) as they were found to be significantly correlated and had the same expression trend as predicted in validation analysis of overall survival (OS) analysis, expression levels, immune infiltration analysis and immunohistochemistry (IHC) analysis. These 5 hub genes can now be exploited in developing novel therapeutic interventions and as diagnostic biomarkers for enhancing the clinical outcomes of MBC patients.

    Integrating photocatalysis with electrocatalysis may represent a synergistic approach to address environmental and energy challenges. In this context, we explored synthesizing a series of nanocomposite materials using a solid-state approach involving simple grinding and subsequent thermal treatment for the photocatalytic purification of dinoseb and electrocatalytic oxygen evolution (OER). Interestingly, among the series of synthesized materials, 40 wt percentage of 3D/2D/1D:ZnFe2O4/NiAl-LDH/MWCNTs ternary nanocomposite (40-NZM) showed highly improved dinoseb detoxification and OER efficiencies compared to those of pure materials. Importantly, approximately 98% detoxification of dinoseb was observed within 75 min of irradiation time under a visible light source. Remarkably, the 40-NZM nanocomposite exhibited the highest rate constant value (k = 4.1 × 10-2 min-1) with a favorable R2 (0.98) parameter. Furthermore, 40-NZM showed promising electrocatalytic OER performance, requiring only 217 mV of overpotential to achieve 10 mAcm-2 of current density with a smaller Tafel slope of 66.6 mVdec-1. Additionally, long-term stability was tested by recording 2000 cyclic voltammetry (CV) cycles. The results revealed that 40-NZM could maintain its catalytic activity for a longer duration as it required only 227 mV to attain 10 mAcm-2 even after 2000 CV cycles. Consequently, these outstanding characteristics of 40-NZM nanocomposite underscore the significant potential for catalytic water purification and sustainable energy conversion.

    Diabetes is one of the most pressing health issues in the Southeast Asian region, and hypertension has been commonly reported as a comorbidity in adults with diabetes. This systematic review aimed to synthesize evidence on the prevalence and management of hypertension in adults with diabetes in Southeast Asian countries. A literature search was conducted in Ovid MEDLINE and Embase Classic + Embase from database inception until March 15, 2024. Studies were included if (1) they were conducted in Southeast Asian countries, (2) the study populations were adults with diabetes, and (3) there was information related to hypertension or blood pressure (BP) in the study results. Of the 7486 abstracts found, 90 studies qualified for this review. Most studies reported a hypertension prevalence of 70% or higher (ranging from 29.4% to 93.4%). Despite this high prevalence, a substantial proportion of these populations did not receive adequate BP control, with most studies indicating a control rate of less than 40%. There was limited evidence on the prescription of antihypertensive therapies and medication adherence. There was a lack of studies from 4 of the 11 countries in the region. This review highlights that BP control in adults with diabetes remains a significant challenge in Southeast Asia. Given the ongoing epidemiological transition, and the increasing older population in this region who are likely to accumulate multiple chronic conditions complicating medication strategies, this review highlights the urgent need to improve BP management in those with diabetes.

    Rechargeable lithium-oxygen (Li-O2) batteries are being considered as the next-generation energy storage systems due to their higher theoretical energy density. However, the practical application of Li-O2 batteries is hindered by slow kinetics and the formation of side products during the oxygen reduction and evolution reactions on the cathode. These reactions lead to high overpotentials during charging and discharging. To address these challenges, we propose a simple ultrasonic method for synthesizing cobalt nanoclusters embedded in nitrogen-doped graphene nanosheets (GrZnCo) derived from metal-organic frameworks (MOFs). The resulting material, due to the retention of metallic cobalt structure, exhibits better electronic conductivity. Additionally, the GrZnCo catalyst shows vigorous catalytic activity, which can improve reaction kinetics and suppress side reactions, thus lowering the charging overpotential. We have investigated the impact of different catalyst compositions (GrZnCox; x  = 1, 3, 5) by varying the amounts of cobalt and zinc. The optimum catalyst, GrZnCo3, contains high cobalt-N active components, graphitic-N, pyridinic-N, pyrrolic-N, and abundant defect structures, which enhance the electrochemical performance. The defect-rich GrZnCo3 catalyst enables Li-O2 batteries to achieve a high discharge capacity of 13500 mAh·g-1 at 50 mA·g-1 and a remarkable long-term cycling performance of over 400 cycles at 100 mA·g-1 with a limited capacity of 500 mAh·g-1. This work demonstrates an effective approach to fabricate cost-effective electrocatalysts for various energy storage systems.

    Amyloid diseases are characterized by the accumulation of misfolded protein aggregates in human tissues, pose significant challenges for both diagnosis and treatment. Protein aggregations known as amyloids are linked to several neurodegenerative conditions including Alzheimer's disease, Parkinson's disease, and systemic amyloidosis. The key goal of this research is to employ Small-Angle X-ray Scattering (SAXS) to examine the supramolecular structures of amyloid aggregates in human tissues. We present the structural analysis of amyloid using SAXS, which is employed directly to analyze thin tissue samples without damaging the tissues. This technique provides size and shape information of fibrils, which can be used to generate low-resolution 2D models. The present study investigates the structural changes in amyloid fibril axial d-spacing and scattering intensity in different human tissues, including kidney, heart, thyroid, and others, while also accounting for the presence of triglycerides in these tissues. Tissue structural components were examined at momentum transfer values between q = 0.2 nm-1 and 1.5 nm-1. The d-spacing is a critical parameter in SAXS that provides information about the periodic distances between structures within a sample. From the supramolecular SAXS patterns, the axial d-spacing of fibrils in amyloid tissues is prominent and exists within the 3rd to 10th order, compared to that of healthy tissues which do not have notable peak orders. The axial period of fibrils in amyloid tissues is within the scattering vector range 57.40-64.64 nm-1 while in normal tissues the range is between 60.68 and 61.41 nm-1, which is 3.0 nm-1 smaller than amyloid-containing tissues. Differences in d-spacing are often correlate with distinct pathological mechanisms or stages of disease progression. The application of SAXS to investigate amyloid structures in human tissues has enormous potential to further knowledge of amyloid disorders. This work will open the path for novel diagnostic instruments and therapeutic strategies meant to reduce the burden of amyloid-related diseases by offering a thorough structural examination of amyloid aggregates.

    The development of a new Neodymium/Dysprosium metal-organic framework, referred to as Nd/Dy-BTC MOF, based on benzene-1,2,4-tricarboxylic acid, has been achieved through an in situ growth process on 2D transition metal carbides (MXene) surfaces. This synthesis was conducted via a solvothermal method utilizing a solvent mixture of water, ethanol, and dimethylformamide. The primary objective of this research is to investigate the framework's efficacy as a photocatalyst for the degradation of anionic dye, as well as its potential for sensing certain explosives. The Nd/Dy-MOF@MXene has been characterized by various analysis techniques. The prepared Nd/Dy-MOF@MXene was utilized as catalyst in selective degradation of methyl orange dye. The study examined the influence of pH and catalyst concentration, revealing that the catalyst achieves peak efficiency of 93.55% when exposed to sunlight in an acidic medium. The reusability of the catalyst shows the highest efficient photocatalyst after four cycles of reusability. The detection of explosives, specifically 2,4,6-trinitrophenol, through photoluminescence techniques has been conducted, utilizing the Stern-Volmer equation to evaluate the quenching efficiency. The findings indicated remarkable efficiency and selectivity of Nd/Dy-MOF@MXene for 2,4,6-trinitrophenol, achieving a quenching efficiency of 91%. Furthermore, the reusability tests demonstrated that Nd/Dy-MOF@MXene exhibits outstanding recyclability, maintaining performance over five cycles. The antibacterial activity of Nd/Dy-MOF@MXene was investigated against Gram-positive and Gram-negative strains due to indication of medicine properties of Nd/Dy-MOF@MXene. These results paves a way for manufacturing innnovation in near future.

    Parrotia subaequalis, an endangered Tertiary relict tree native to China and a member of the Hamamelidaceae family, is one of several host plant species in this family that exhibit unique ecological habits, such as gall formation. Tree galls are the results of complex interactions between gall-inducing insects and their host plant organs. The formation of galls may serve to protect other regions of the plant from potential damage, often through the production of phytoalexins. In this study, a preliminary investigation was carried out on the metabolites of the 90% MeOH extract derived from the closed spherical galls on the twigs of P. subaequalis. Consequently, nine previously undescribed benzofuran-type and dibenzofuran-type phytoalexins (parrotiagallols A-I, 1-9, respectively) were isolated and characterized, along with several known miscellaneous metabolites (10-17). Their chemical structures and absolute configurations were elucidated using spectroscopic methods, a combination of calculated and experimental electronic circular dichroism data, and single crystal X-ray diffraction analyses. Among these compounds, 1 and 2 are identified as neolignan derivatives, while compounds 3-5 are classified as 9,10-dinorneolignans. Compound 6 represents a rare 2,3-seco-neolignan, and compounds 7-9 are dihydroxy-dimethyl-dibenzofuran derivatives. Parrotiagallol A (1) showed considerable antibacterial activity against Staphylococcus aureus, with an MIC value of 14 μM. Additionally, parrotiagallol E (5) and methyl gallate (17) exhibited inhibitory effects against ATP-citrate lyase (ACL), a potential therapeutic target for hyperlipidemia, with IC50 values of 5.1 and 9.8 μM, respectively. The findings underscore that galls not only serve as physical defense barriers but also benefit from the chemical defense system of the host plants. These insights provide avenues for exploring potential new therapeutic agents for S. aureus infections and ACL-related diseases, while also promoting scientific conservation strategies for P. subaequalis.

    OBJECTIVES: Kratom preparation containing Mitragyna speciosa Korth plant is frequently used as a recreational drug. Mitragynine, a major alkaloid isolated from M. speciosa, is often detected concurrently with other drugs during forensic analysis, indicating a safety concern. P-glycoprotein (P-gp) is a multidrug transporter. Modulation of P-gp transport activity by drugs or herbal compounds in the brain may lead to drug-herb interactions, resulting in neurotoxicity. We aim to determine the effects of mitragynine on the P-gp regulation and possible neurotoxicity.

    METHODS: The effects of mitragynine on the P-gp regulation were investigated in human brain capillary endothelial cells (hCMEC/D3) using molecular docking and dynamic simulation and an optimized bidirectional transport assay, respectively. Repeated-dose treatment and neurotoxicity assessment were carried out using a blood-brain barrier model and polimerase chain reaction (PCR) array.

    KEY FINDINGS: Mitragynine inhibits the P-gp transport activity via binding onto the nucleotide-binding domain site and forms a stable interaction with the P-gp protein complex. Nontoxic concentrations of mitragynine (<4 μM) and substrate drugs (0.001 μM) in the cells significantly enhanced endothelial cell permeability and elicited signs of neurotoxicity in PC-12 cells.

    CONCLUSIONS: Mitragynine is likely a P-gp inhibitor, hence concurrent administration of kratom products with P-gp substrates may lead to clinically significant interactions and neurotoxicity.

Objective evaluation included Pelvic Organ Prolapse Quantification (POP-Q), multichannel urodynamic (UDS), and introital 2D ultrasonographic measurement. Subjective evaluation uses validated questionnaires of Incontinence Impact Questionnaire-7(IIQ-7), Urogenital Distress Inventory-6(UDI-6), Pelvic Organ Prolapse Distress Inventory 6(POPDI-6), Colorectal Anal Distress Inventory-8(CRADI-8) and Pelvic organ prolapse/ Urinary Incontinence Sexual Questionnaire (PISQ-12). Outcomes were examined at 3 months, yearly and at 3 years postoperative. Secondary outcome included de novo or persistent urodynamic stress incontinence (USI) and surgical complications.

    RESULTS: Eighty-five women were included in the final analysis. At 3 years postoperative, the objective cure rate was 94.1 % and subjective cure rate of 91.8 %. Ultrasonography revealed initial mesh elongation and thickening at first year, resolving by the third year, while the distance between the bladder neck and mesh remained stable. Significant improvement in POP-Q components (Aa,Ba,C,Ap,Bp and TVL of p

    Recently, dermatology has increasingly focused on understanding skin aging and exploring novel therapeutic approaches. Despite progress in cosmetic and pharmaceutical research, a significant gap remains in comprehensively understanding the effects and mechanisms of herbal extracts on skin aging. While many studies have examined the bioactivities of herbal compounds in preclinical models, comprehensive human trials have been scarce over the past decade. This review aims to address this gap by synthesizing human trials from the past decade, focusing on the therapeutic effects of herbal extracts on skin aging. The objective is to unravel the mechanisms contributing to skin aging and assess the therapeutic potential of herbal compounds. Following the PRISMA 2020 guideline, a systematic review was performed across OvidMEDLINE, Cochrane Central Register of Controlled Trials, and Embase via Ovid. A meticulous search strategy identified relevant clinical trials. The review highlights the essential role of herbal compounds in skin aging, particularly their antioxidant activity in suppressing the aging process. Analysis of 51 clinical trials offers valuable insights into their diverse effects on skin aging parameters. Herbal compounds are promising alternatives to synthetic products for treating skin aging. Their demonstrated efficacy in mitigating wrinkles, enhancing elasticity, maintaining hydration, and controlling pigmentation underscores their potential in developing antiaging therapeutics. However, further studies are needed to identify specific compounds responsible for these effects and understand their mechanisms. Future directions include conducting large-scale trials, exploring synergies with other ingredients, and optimizing delivery systems for sustainable, effective antiaging therapies.

    BACKGROUND: In the absence of significant pleural effusion, conventional medical thoracoscopy (MT) is often not feasible due to the risk of lung injury. Dry MT mitigates these risks by inducing artificial pneumothorax through needle insufflation or blunt dissection. Although the Veress needle is commonly used by surgeons to create pneumoperitoneum before laparoscopic surgeries, its application in dry MT has not been widely reported in recent times.

    METHODS: We report on a series of 31 patients who underwent dry MT with artificial pneumothorax induction using Veress needle under thoracic ultrasonography (TUS) guidance. A procedure was considered technically successful if it met all the following criteria: successful pneumothorax induction, allowing smooth insertion of the semi-rigid thoracoscope; absence of immediate significant procedural-related complications; and no delayed complications such as persistent air leaks, defined as leakage lasting more than 5 days necessitating extended chest tube placement.

    RESULTS: Complete pneumothorax induction was achieved in 25 cases, resulting in an 80.6% technical success rate; however, biopsies were successfully performed in all cases. The most frequent histopathological diagnoses were malignancy (n=9, 29.0%), followed by inflammatory pleuritis (n=8, 25.8%) and tuberculosis (n=8, 25.8%). No procedural complications were reported.

    CONCLUSION: These results indicate that TUS-guided dry MT utilizing a Veress needle is technically feasible and secure when performed by experienced MT practitioners in TUS.
