In situ Generation of Cyclohexanone Drives Electrocatalytic Upgrading of Phenol to Nylon-6 Precursor.

Coupling in situ generated intermediates with other substrates/intermediates is a viable approach for diversifying product outcomes of catalytic reactions involving two or multiple reactants. Cyclohexanone oxime is a key precursor for caprolactam synthesis (the monomer of Nylon-6), yet its current production uses unsustainable carbon sources, noble metal catalysts, and harsh conditions. Herein, we report the first work to synthesize cyclohexanone oxime through electroreduction of phenol and hydroxylamine. The Faradaic efficiency reached 69.1% over Cu catalyst, accompanied by a corresponding cyclohexanone oxime formation rate of 82.0 g h-1 gcat-1. In addition, the conversion of phenol was up to 97.5%. In situ characterizations, control experiments, and theoretical calculations suggested the importance of balanced activation of water, phenol, and hydroxylamine substrates on the optimal metallic Cu catalyst for achieving high-performance cyclohexanone oxime synthesis. Besides, a tandem catalytic route for the upgrading of lignin to caprolactam has been successfully developed through the integration of thermal catalysis, electrocatalysis, and Beckmann rearrangement, which achieved the synthesis of 0.40 g of caprolactam from 4.0 g of lignin raw material.

Digital Health and Self-Management in Idiopathic Inflammatory Myopathies: A Missed Opportunity?

This paper explored the potential of digital health in idiopathic inflammatory myopathies (IIMs), with a focus on self-management. Digital self-management technology includes tailored treatment plans, symptom tracking, educational resources, enhanced communication, and support for long-term planning. After arguing the importance of digital health in IIMs management, from diagnosis until treatment, our literature review revealed a notable gap in research focusing on the efficacy of digital self-management interventions for individuals with IIMs, with no randomised controlled trials or observational studies addressing this topic. Our review further highlighted the significant unmet need for research in self-management interventions for individuals with IIMs. The absence of studies underscores the necessity for collaborative efforts to address this gap and develop personalised, effective strategies for managing IIMs using digital technology. Individuals with IIMs deserve tailored self-management approaches akin to those available for other rheumatic and musculoskeletal diseases.

Bright New Resources for Syphilis Research: Genetically Encoded Fluorescent Tags for Treponema pallidum and Sf1Ep Cells.

The recently discovered methodologies to cultivate and genetically manipulate Treponema pallidum subsp. pallidum (T. pallidum) have significantly helped syphilis research, allowing the invitro evaluation of antibiotic efficacy, performance of controlled studies to assess differential treponemal gene expression, and generation of loss-of-function mutants to evaluate the contribution of specific genetic loci to T. pallidum virulence. Building on this progress, we engineered the T. pallidum SS14 strain to express a red-shifted green fluorescent protein (GFP) and Sf1Ep cells to express mCherry and blue fluorescent protein (BFP) for enhanced visualization. These new resources improve microscopy- and cell sorting-based applications for T. pallidum, better capturing the physical interaction between the host and pathogen, among other possibilities. Continued efforts to develop and share new tools and resources are required to help our overall knowledge of T. pallidum biology and syphilis pathogenesis reach that of other bacterial pathogens, including spirochetes.

No observable non-thermal effect of microwave radiation on the growth of microtubules

Despite widespread public interest in the health impact of exposure to microwave radiation, studies of the influence of microwave radiation on biological samples are often inconclusive or contradictory. Here we examine the influence of microwave radiation of frequencies 3.5 GHz, 20 GHz and 29 GHz on the growth of microtubules, which are biological nanotubes that perform diverse functions in eukaryotic cells. Since microtubules are highly polar and can extend several micrometres in length, they are predicted to be sensitive to non-ionizing radiation. Moreover, it has been speculated that tubulin dimers within microtubules might rapidly toggle between different conformations, potentially participating in computational or other cooperative processes. Our data show that exposure to microwave radiation yields a microtubule growth curve that is distorted relative to control studies utilizing a homogeneous temperature jump. However, this apparent effect of non-ionizing radiation is reproduced by control experiments using an infrared laser or hot air to heat the sample and thereby mimic the thermal history of samples exposed to microwaves. As such, no non-thermal effects of microwave radiation on microtubule growth can be assigned. Our results highlight the need for appropriate control experiments in biophysical studies that may impact on the sphere of public interest.

Highly Selective Production of C2+ Oxygenates from CO2 in Strongly Acidic Condition by Rough Ag-Cu Electrocatalyst.

The acidic electrocatalytic conversion of CO2 to multi-carbon (C2+) oxygenates is of great importance in view of enhancing carbon utilization efficiency and generating products with high energy densities, but suffering from low selectivity and activity. Herein, we synthesized Ag-Cu alloy catalyst with highly rough surface, by which the selectivity to C2+ oxygenates can be greatly improved. In a strongly acidic condition (pH=0.75), the maximum C2+ products Faradaic efficiency (FE) and C2+ oxygenates FE reach 80.4% and 56.5% at -1.9 V versus reversible hydrogen electrode, respectively, with a ratio of FEC2+ oxygenates to FEethylene up to 2.36. At this condition, the C2+ oxygenates partial current density is as high as 480 mA cm-2. The in situ Raman measurements and control experiments indicate that the high generation of C2+ oxygenates over the catalyst originates from its large surface roughness and Ag alloying.

Transition-metal free, radical oxidation of 1,6-enyne cyclopropanation: synthesis of aza-bicyclo[4.1.0]heptane derivatives.

A straightforward transition-metal-free sustainable methodology for oxidative cyclopropanation of aza-1,6-enynes has been devised, enabling the synthesis of valuable, functionalized azabicyclo[4.1.0]heptane-2,4,5-triones, via four bond formation in a single step under mild conditions. Control experiments and real-time mass data monitoring using online ESI-MS spectroscopy support the pathway proposed for this reaction. The synthesized products have been utilized in diverse product transformations. Key advantages of this reaction include its operational ease, transition metal-free nature, rapid completion, and compatibility with a wide range of functional groups and substrates.

A systematic review and meta-analysis compared the safety and effectiveness of the AirSeal system with traditional pneumoperitoneum systems in robot-assisted laparoscopic urologic surgery.

This study aimed to analyze perioperative results in robot-assisted laparoscopic urological surgeries, comparing the AirSeal system with traditional pneumoperitoneum systems. This study adhered to the PRISMA guidelines for conducting systematic reviews and meta-analyses. Extensive searches were conducted in PubMed, EMBASE, and Google Scholar, including randomized controlled trials (RCTs) and cohort studies up to June 15, 2024. A combined examination of the studies found that the AirSeal system had superior results in terms of surgery duration, end-tidal carbon dioxide levels, and tidal volume compared to the traditional pneumoperitoneum system. During robotic-assisted partial nephrectomy, the AirSeal team experienced a notable decrease in surgical time, ETCO2, and VT. In addition, the occurrence of SCE was lower in the AirSeal group. However, there were no significant differences observed between the groups regarding EBL, LOHS, overall complications, and major complications. Compared to conventional pneumoperitoneum systems, the AirSeal system offers several advantages in robot-assisted laparoscopic urological surgery: reduced operative time, lower end-tidal CO2 pressure, and decreased tidal volume. Furthermore, implementing the AirSeal system does not lead to higher rates of complications, estimated blood loss, or lengthier hospital stays.

Iridium-Catalyzed Asymmetric Hydroarylation of Unactivated Alkenes with Heterobiaryls: Simultaneous Construction of Axial and Central Chirality.

There are only a few examples being reported for the simultaneous control of central chirality and axial chirality because it is more challenging. Herein, we report an iridium-catalyzed asymmetric hydroarylation of unactivated alkenes with heterobiaryls to simultaneously construct axial and central chirality. The reaction showed a broad substrate scope and delivered the products with satisfactory results. The results of the control experiments demonstrated that the FerroLANE ligand promotes the reaction to proceed along a specific modified Chalk-Harrod mechanism.

A randomized controlled study of neoadjuvant metformin with chemotherapy in nondiabetic breast cancer women: The METNEO study.

Clinical data demonstrate that metformin exhibits antiproliferative, proapoptotic and antimetastatic actions. Here, correlative molecular studies were undertaken to determine the roles of transmembrane tumour necrosis factor-related apoptosis-inducing ligand death receptors (DRs) and CD133, a glycoprotein biomarker of breast cancer (BC) stem cells, in the advantageous action of metformin on pathological and clinical outcomes in BC patients on neoadjuvant chemotherapy. We randomly assigned 70 nondiabetic BC patients in a 1:1 ratio to either neoadjuvant AC-T chemotherapy (4cycles of adriamycin 60 mg/m2 and cyclophosphamide 600 mg/m2, followed by 12 cycles of weekly paclitaxel 80 mg/m2) or AC-T with adjunct metformin (850 mg twice/day). The expressions of DR4, DR5 and CD133 were quantified in excised tissue samples with residual tumour cells. The overall clinical response (odds ratio: 22.67 [2.77-185.18], P= .004), breast-conserving surgery (odds ratio: 3.67 [1.303-10.321], P= .014) and pathological complete response (β =2.49 ±1.13 [0.274-4.712], P= .028) rates were significantly improved in the metformin arm. Tissues obtained from the metformin arm had upregulated mRNA expression of DR4 (Mean delta cycle thresholds ± standard error of the mean: 2.68 ±0.25 vs. 4.87 ±0.53, P= .0003) and DR5 (0.21 ±0.25 vs. 4.29 ±0.95, P= .0004) compared to control arm. The enhanced DR expression negatively correlated with that of CD133 + BC stem cells, which was significantly reduced by metformin at both cytoplasmic/membranous (43.48 vs. 100.00%, P< .0001) and nuclear sites (4.35 vs. 95.00%, P< .0001). Metformin improves clinical and pathological responses to neoadjuvant AC-T chemotherapy in BC via prompting directionally opposite changes in DRs (increments) and CD133 + (decrements) expressions. This study was registered in ClinicalTrials.gov (registration number: NCT04170465, https://clinicaltrials.gov/ct2/show/NCT04170465).

The Role of Health Literacy in Skin Cancer Preventative Behavior and Implications for Intervention: A Systematic Review.

Health literacy is essential for individuals to access, understand, and utilize information and services to inform health related decisions and actions. As one of the most diagnosed and preventable forms of cancer, skin cancer disease risk can be reduced through preventative behavior. Currently, there is no focused study looking specifically at health literacy and skin cancer. An understanding of how health literacy affects skin cancer-related preventive behaviors can improve current practices in skin cancer prevention. To systematically identify, synthesize, and summarize findings on the role of health literacy in skin cancers (including cutaneous squamous cell carcinoma, basal cell carcinoma, and melanoma), with a focus on preventive behaviors using studiesthat utilized quantifiablehealth literacy measurements. A literature search was performed by searching PubMed, Embase, PsycINFO, and CINAHL from inception until September 26, 2023 to identify cross-sectional, case-control, cohort, or randomized controlled studies that investigated the association between health literacy and skin cancer prevention and diagnosis. Health literacy levels varied across geographic regions, specific populations, and ethnicities. Most of the included studies found a positive association between higher health literacy and better skin cancer preventative behaviors. This included sun-protective behaviors such as: wearing sleeved shirts or shirts with collars, using gloves, covering head and face, limiting sun exposure, more sunscreen use, and less sunbathing or indoor tanning. Higher health literacy was associated with increased likelihood to engage in genetic testing and less family influence on health in one study which assessed determinants of interest in skin cancer genetic testing. Another study investigating family communication about skin cancer found that higher health literacy was associated with increased family communication regarding general cancer risk. One sun protection interventional education program was effective at increasing participants' knowledge, awareness of skin cancer risk, willingness to change sun protection, and use of sun protection, but results varied between ethnic groups. Skin cancer-related educational interventions can be effective in improving health literacy and potentially lessen the impact of skin cancer through positive behavior modification, early detection, and disease knowledge and awareness. Interventions need to be tailored to its target population to maximize effectiveness due to thevarying baseline of health literacy identified across different geographic and ethnic groups.

The effect of nursing interventions applied at home to improve rational use of medicines and awareness of elderly individuals: A randomized controlled study.

The aim of this study was to evaluate the effect of nursing interventions applied to elderly individuals to improve rational use of medicines (RUM) and awareness through home visits. It was carried out in a prospective, randomized controlled experimental design with the pretest-post-test control group. The study was completed with 74 elderly individuals aged ≥65 years living in a rural area. The intervention group received education, counselling, brochures and pill boxes through home visits to increase RUM and awareness. The study data were collected between September and December 2022 using the face-to-face interview method, the elderly identification form, the Rational Use of Medicines Scale and the Rational Drug Use Awareness Scale. After nursing interventions were applied at home, it was determined that, the mean scores of RUM and Awareness of RUM of the intervention group increased compared to the control group and that, interventions to improve RUM and awareness were effective. In line with these results, training sessions on RUM should be organized periodically for elderly individuals and home visits should be planned by nurses at regular intervals to ensure the sustainability of RUM in the home environment.

Case–Control and Cohort Studies in Homeopathy: Part 4 of the Research Method Series

AbstractCase–control and cohort studies are fundamental epidemiological research designs utilized to investigate the relationship between exposures and outcomes in medical research. This paper provides a comparative analysis of these two study designs, focusing on their respective strengths, applications, and implications for understanding disease etiology, progression, and intervention effectiveness. Case–control studies offer a retrospective lens, enabling researchers to assess the impact of exposures on disease development by comparing individuals with a particular outcome (cases) to those without (controls). Through meticulous selection and analysis, case–control studies unveil potential risk factors and causal relationships, particularly beneficial for investigating rare diseases or long latency periods. Conversely, cohort studies adopt a prospective approach, following a group of individuals over time to evaluate the incidence of outcomes in relation to exposures. This design facilitates the assessment of cumulative exposure effects, disease progression, and intervention efficacy, providing valuable insights into the natural history of diseases. In the context of homeopathy, both the study designs may be utilized for the evaluation of long-term treatment effects, disease progression, and patient satisfaction, shedding light on the holistic nature of homeopathic care. By embracing rigorous methodologies and leveraging the strengths of both study designs, researchers in homeopathy can advance evidence-based practice, enhancing our understanding of homeopathic principles and their practical implications in clinical settings.

Lewis Base-Catalyzed Dynamic Kinetic Asymmetric Transformation of Racemic Chlorosilanes en Route to Si-Stereogenic Silylethers.

Enantiopure Si-stereogenic organosilanes are highly valued in the fields of organic synthesis, development of advanced materials, and drug discovery. However, they are not naturally occurring, and their synthesis has been largely confined to resolution of racemic silanes or desymmetrization of symmetric silanes. In contrast, the dynamic kinetic asymmetric transformation (DYKAT) of racemic organosilanes offers a mechanistically distinct approach and would broaden the accessibility of Si-stereogenic silanes in an enantioconvergent manner. In this study, we report a Lewis base-catalyzed DYKAT of racemic chlorosilanes. The chiral isothiourea catalyst, (S)-benzotetramisole, facilitates silyletherification with phenols, yielding (R)-silylethers in good yields with high enantioselectivity (27 examples, up to 86% yield, up to 98:2 er). Kinetic analysis, control experiments, and DFT calculations suggest that a two-catalyst-bound pentacoordinate silicate is responsible for the Si-configurational epimerization of the ion-paired tetracoordinated silicon intermediates.

Visible‐Light Induced Ag‐Palladacycle‐Complex‐Mediated Regioselective C−H Arylation

AbstractA visible‐light‐induced, external photocatalyst‐free, site‐selective C−H arylation of 4H‐pyrido[1,2‐a]pyrimidin‐4‐ones and various 2‐aryl heteroarenes has been developed to provide ortho arylated products 41–95% yield at room temperature. A mechanistic study using control experiments, UV‐visible study, DFT study, and observation of colored aggregates suggest that in situ generated Ag‐palladacycle complex of 2‐aryl heteroarenes is responsible for absorbing the visible light and generating aryl radicals from aryldiazonium salts. Further, this methodology demonstrates its versatility by transforming various 2‐aryl heteroarenes, including 2‐phenylquinazolin‐4(3H)‐one, 3‐phenylquinoxalin‐2(1H)‐one, 2‐phenylpyridines, pyrazolo[1,5‐a]pyrimidines, 2‐phenylquinolines, 2‐phenylisoquinolines, and 2‐phenylbenzo[d]thiazoles, into their respective regio‐selective C−H arylated products under mild reaction conditions.

Does the oral microbiota evolve differently during orthodontic treatment with vestibular multi-attachment fixed appliances versus aligners? A systematic review of the literature

Oral microbiota of patients is impacted during orthodontic treatment. The objective of this systematic review was to observe the evolution of oral microbiota (primary objective) and periodontal health (secondary objective) during orthodontic treatment, and to compare these changes during treatment with vestibular fixed appliances and aligners. In accordance with PRISMA guidelines, an electronic search was performed in four databases until January 2022, completed by a manual search, including all prospective controlled studies, randomized or not, on the subject. Two independent authors were involved in the selection of studies, and a third author was consulted in case of disagreement. The Cochrane Collaboration's tool and ROBINS-I tool was used to assess the risk-of-bias in randomized and non-randomized trials, respectively. Finally, the risk of bias graphs were made with the robvis visualization tool. Out of the 994 results obtained from these searches, 11 eligible articles were included (4 randomized clinical trials and 7 non-randomized controlled studies) with varying levels of bias. Results suggested that patients treated with aligner appliances have more favorable microbial flora and less biofilm mass during their treatment compared with those treated with fixed appliances. In addition, inflammatory marker cytokines and periodontal indices were higher in fixed orthodontic treatment compared to aligners treatment. Considering the limitations of this systematic review of the literature, the results suggested that aligners have a more favorable impact on the oral microbiota and periodontium compared to vestibular fixed appliances.

Leveraging real-world Data from administrative claims and medical records to inform safety and effectiveness of piperacillin-tazobactam in the Management of Pediatric Hospital Acquired Pneumonia.

Pediatric-specific safety data are required during development of pharmaceutical agents. Retrospective studies can leverage real-world data to assess safety and effectiveness in children where prospective, controlled studies are not feasible. A retrospective cohort study combined data from Pediatric Health Information Systems (PHIS) and medical records to evaluate the safety and effectiveness of piperacillin/tazobactam (P/T) in pediatric patients with hospital-acquired pneumonia (HAP). After identifying 407 patients diagnosed with HAP receiving P/T (n=140) or Comparator (n=267) HAP-appropriate antibiotics between 2003-2016 across seven pediatric institutions, we evaluated comparative risk of a serious adverse event (SAE). Clinical improvement 14 days after therapy initiation was studied as a secondary outcome. Incidence rate ratios (IRRs) were calculated to compare between exposure groups using inverse probability-weighted Poisson regression models. The unadjusted and adjusted IRRs with 95% CIs for SAEs were 1.26(0.66-2.39) and 1.24(0.65-2.35). The unadjusted and adjusted ORs with 95% CIs for clinical improvement were 1.14(0.56-2.34) and 1.50(0.67-3.38). Point estimates from this retrospective analysis suggest similar safety and clinical effectiveness of P/T and comparator antibiotics for treating HAP. However, due to wide CIs, actual between-group differences cannot be excluded. Existing real-world data can be utilized to inform pediatric-specific safety and effectiveness of medications used in off-label settings.

Metacognitive Therapy Versus Cognitive Behavioral Therapy for OCD: A Randomized Controlled Trial

Background and Objectives: Obsessive-compulsive disorder (OCD) is a disabling condition with a lifetime prevalence of approximately 2 - 3% in the general population. This paper presents the first controlled study that examines the effects of CBT compared with MCT in the treatment of OCD. Methods: This paper presents an experimental study carried out individually with group-level comparison. Using a parallel design, participants were randomly assigned to either CBT or MCT. The study was conducted in the psychiatric clinic of Imam Hossein Hospital in Tehran, Iran. Of the 47 participants who were assessed, 27 started treatment (CBT = 13, MCT = 14), and 24 were available for a three-month follow-up. Participants were randomly assigned to either 10 weeks of CBT or MCT. Results: Clinically significant changes on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) using Jacobson methodology/Asymptomatic criteria as the index of outcome were 16.7%/0% and 66.7%/41.7% in CBT and MCT, respectively. With respect to Y-BOCS, the effect sizes of MCT (3.28) at post-test and one-month follow-up were higher than that of CBT (1.66). Although both interventions were efficacious in reducing disorder severity, improving QoL, and functioning at post-test, MCT was statistically and clinically more significant. Both interventions led to equally high reductions in depression and anxiety that were apparent in the two follow-ups. Symptom reduction on the Y-BOCS was stable or slightly improving in MCT; however, recovery rates in CBT declined. Conclusions: It is possible that change in MCT occurs through more direct alteration in the brain’s executive function (EF) and modification of EF inputs, addressing a major problem of OCD. Further replication is required as MCT offers a promising alternative treatment approach.

Surgical advantage of modified labial salivary gland biopsy using chalazion forceps: a prospective randomized controlled study

Labial salivary gland biopsy (LSGB) is one of the specific diagnostic criteria for primary Sjögren's syndrome (pSS). In traditional LSGB, there is no lower lip fixation device, the field of view is unclear due to intraoperative bleeding, and the incision is large, which is unfavourable for healing. The use of auxiliary devices to improve the shortcomings of traditional LSGB technique would be meaningful. Therefore, this case–control study aimed to assess the value of modified LSGB using chalazion forceps as compared with traditional LSGB. After obtaining written informed consent from all participating parents and patients, we randomly assigned 217 eligible participants to undergo LSGB using chalazion forceps (n = 125) or traditional LSGB (n = 92). The outcome variables were surgical time, incision length, intraoperative bleeding, pain score at 24 h after surgery, incision healing status at 7 days after surgery, gland collection, and pathological results. The final diagnostic results of the two surgical methods were compared, and the match rates between the pathological results and the final clinical diagnoses were compared between the two groups. The data were analysed using parametric and nonparametric tests. Compared with the traditional group, the modified group had a smaller incision, shorter operative time, less blood loss, lower 24 h pain score, and better Grade A incision healing at 7 days after surgery (p < 0.01). There was no statistically significant difference between the patients in the two surgical-method groups in terms of the positive biopsy results and the final diagnosis based on expert opinions (p > 0.05). By multivariable regression analysis, only a focus score (FS) of ≥ 1 (p < 0.01), dry eye disease (p < 0.05) and anti-nuclear antibodies (ANA) titre ≥ 1:320 (p < 0.05) were correlated with the diagnosis of pSS. The positive biopsy results of patients in the different surgical-method groups had a biopsy accuracy of > 80.0% for the diagnosis of pSS. The positive biopsy results in the different surgical-method groups were consistent with the expert opinions and the 2016 ACR-EULAR primary SS classification criteria. The modified LSGB using an auxiliary chalazion forceps offers a good safety with a small incision, shorter operative time, less bleeding, reduced pain and a low incidence of postoperative complications.The match rate of LSGB pathological results of the proposed surgical procedure with the final diagnosis of pSS is high.

Diiron Complexes with Rigid and Conjugated S-to-S Bridges for Electrocatalytic Reduction of CO2.

Electroreduction of CO2 to value-added low-carbon chemicals is a promising way for carbon neutrality and CO2 utilization. It was found that the diiron complex [(μ-bdt)Fe2(CO)6] (bdt = benzene-1,2-dithiolate) has high catalytic activity for electrocatalytic CO2 reduction. To further study the effect of the S-to-S bridge on the catalytic performances of diiron complexes for electrochemical CO2 reduction, four diiron complexes 1-4 with different rigid and conjugated S-to-S bridges were either selected or designed. The electrocatalytic studies showed that under optimal conditions, 2 with a 2,3-naphthalenedithiolato bridge exhibited the lowest catalytic onset potential (Eonset = -1.75 V vs Fc+/0), while 4 with a diphenyl-1,2-vinylidene bridge displayed the highest catalytic activity (TOFmax = 295 s-1), which is 1.5 times that of [(μ-bdt)Fe2(CO)6]. The controlled potential electrolysis experiments of 4 in 0.1 M MeOH/MeCN at -2.35 V vs Fc+/0 gave a total faradaic yield close to 100%, with selectivities of 77%, 9%, and 14% for HCOOH, CO, and H2, respectively. The mechanism for CO2 reduction was studied using density functional theory, IR spectroelectrochemistry, and electrochemical methods. The results indicate that modifying the structure of the S-to-S bridge is an effective strategy to improve the catalytic performance of diiron complexes for electrocatalytic CO2 reduction.

Effect of 10-week Isometric handgrip exercise at home on hemodynamic and psychological factors of sedentary hypertensive women during COVID-19

Background and Objective: COVID-19 poses significant public health threats and impacts physical activity, particularly in hypertensive patients. The aim of this study is to examine the ten weeks of isometric handgrip exercise impact on hypertensive women during quarantine. Methods: thirty female volunteers with high blood pressure participated in this randomized controlled trial study. The isometric handgrip (IHG) exercise group performed the exercise for ten weeks (3 sessions per week, 4x2 min isometric contractions at 30% MVC, separated by 2 minutes rest) via video call at home, and the control group had no exercise program. The blood pressure (systolic, diastolic, and mean), heart rate, and myocardial oxygen consumption were measured before and after exercise program; DASS21 and quality of life (Sf-36) questionnaires were then completed by the participants. Results: Systolic, diastolic, and mean blood pressure showed a significant decrease (5 mmHg, 2 mmHg, respectively); quality of life and DASS21 scores showed a significant improvement after IHG exercise compared to the control (p &lt; .05). Conclusion: IHG exercise activity at home is highly effective and useful for improving blood pressure and quality of life of hypertensive women, and it is also a treatment option to reduce stress, depression and anxiety due to COVID-19.
