RESUMO

BACKGROUND: Surgery plays a key role in the multi-disciplinary cancer care pathway. Nearly 80% of patients with solid tumors will require surgical intervention during the course of their disease. Unfortunately, the vast majority of these patients do not have access to safe, timely, high-quality, and affordable cancer surgical care. The first Lancet Oncology Commission on Global Cancer Surgery shone a light on this grave situation and outlined some strategies to address them. The second Lancet Oncology Commission on Global Cancer Surgery (TLO- II) was conceived to continue the work of its predecessor by developing a roadmap of practical solutions to propel improvements in cancer surgical care globally. METHODS: The Commission was developed by involving approximately 50 cancer care leaders and experts from different parts of the world to ensure diversity of input and global applicability. RESULTS: The Commission identified nine solutional domains that are considered essential to deliver safe, timely, high-quality, and affordable cancer surgical care. These nine domains were further refined to develop solutions specific to each of the six World Health Organization regions. Based on the above solutions, we developed eight action items that are intended to propel improvements in cancer surgical care on the global stage. CONCLUSIONS: The second Lancet Oncology Commission on Global Cancer Surgery builds on the first Commission by developing a pragmatic roadmap of practical solutions that we hope will ensure access to safe, timely, high-quality, and affordable cancer surgical care for everyone regardless of their socioeconomic status or geographic location.

RESUMO

The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.

RESUMO

The main purpose of the study was to conduct a comprehensive needs assessment of primary healthcare professionals in order to develop a training program aimed at enhancing competencies in suicide risk assessment and management. A total of 144 primary healthcare professionals (physicians = 46; primary care workers = 98) completed the needs assessment questionnaire. The majority of healthcare professionals rated their level of comfort and competence in assessing, treating, and referring suicidal patients as medium or high. However, their knowledge about suicide, risk factors for suicide, asking about suicidal behaviour, and helping a suicidal patient was rated low or medium. Overall, the scarcity of qualified healthcare professionals and the existing gaps in core competencies for suicide risk assessment and management was identified. Development of innovative and effective competencies-based suicide specific training for primary care providers in India is urgently required.

RESUMO

BACKGROUND: Rotavirus is the most common cause of severe dehydrating gastroenteritis in developing countries. Safe, effective, and affordable rotavirus vaccines are needed in these countries. We aimed to assess the efficacy and tolerability of a monovalent human-bovine rotavirus vaccine for severe rotavirus gastroenteritis in low-resource urban and rural settings in India. METHODS: We did a randomised double-blind, placebo-controlled, multicentre trial at three sites in Delhi (urban), Pune (rural), and Vellore (urban and rural) between March 11, 2011, and Nov 5, 2012. Infants aged 6-7 weeks were randomly assigned (2:1), via a central interactive voice or web response system with a block size of 12, to receive either three doses of oral human-bovine natural reassortant vaccine (116E) or placebo at ages 6-7 weeks, 10 weeks, and 14 weeks. Infants' families, study investigators, paediatricians in referral hospitals, laboratory staff, and committee members were all masked to treatment allocation. The primary outcome was incidence of severe rotavirus gastroenteritis (≥11 on the Vesikari scale). Efficacy outcomes and adverse events were ascertained through active surveillance. Analysis was by intention to treat and per protocol. The trial is registered with Clinical Trial Registry-India (CTRI/2010/091/000102) and ClinicalTrials.gov (NCT01305109). FINDINGS: 4532 infants were assigned to receive the 116E vaccine and 2267 to receive placebo, of whom 4354 (96%) and 2187 (96%) infants, respectively, were included in the primary per-protocol efficacy analysis. 71 events of severe rotavirus gastroenteritis were reported in 4752 person-years in infants in the vaccine group compared with 76 events in 2360 person-years in those in the placebo group; vaccine efficacy against severe rotavirus gastroenteritis was 53·6% (95% CI 35·0-66·9; p=0·0013) and 56·4% (36·6-70·1; p<0·0001) in the first year of life. The number of infants needed to be immunised to prevent one severe rotavirus gastroenteritis episode was 55 (95% CI 37-97). The incidence of severe rotavirus gastroenteritis per 100 person-years was 1·5 in the vaccine group and 3·2 in the placebo group, with an incidence rate ratio of 0·46 (95% CI 0·33-0·65). Prevalence of immediate, solicited, and serious adverse events was similar in both groups. One case of urticaria in the vaccine group and one each of acute gastroenteritis and suspected sepsis in the placebo group were regarded as related to the study product. We recorded six cases of intussusception in the vaccine group and two in the placebo group, all of which happened after the third dose. 25 (<1%) infants in the vaccine group and 17 (<1%) in the placebo group died; no death was regarded as related to the study product. INTERPRETATION: Monovalent human-bovine (116E) rotavirus vaccine is effective and well tolerated in Indian infants.

RESUMO

INTRODUCTION: There are limited numbers of studies on Dhat syndrome. Major limitations of the existing literature are heterogeneous assessment methods used to describe the comorbidity and small sample size from isolated centers. AIM: To assess comorbidity with a common methodology in patients with Dhat syndrome from multiple centers across India. METHODS: Using a cross-sectional design, this multicentric study involved assessment of 780 male patients, aged more than 16 years, across 15 study centers. MAIN OUTCOME MEASURES: ICD-10 criteria (for evaluation of psychiatric morbidity and sexual dysfunction) RESULTS: About one-third (32.8%) of the cases had no comorbidity. One-fifth (20.5%) of the patients had comorbid depressive disorders and another one-fifth (20.5%) had comorbid neurotic, stress-related and somatoform disorders. Half (51.3%) of the study sample had comorbid sexual dysfunction. When various combinations of comorbidities were evaluated, it was seen that more than one-fourth (28.7%) of the patients had only comorbid sexual dysfunction and one-sixth (15.9%) had only comorbid depressive/anxiety disorders. A little more than one-fifth (22.6%) had comorbidity of both sexual dysfunction and depressive/anxiety disorders. CONCLUSION: Comorbid sexual dysfunction is seen in half of the cases of Dhat syndrome, and it is more common than comorbid depressive and anxiety disorders.

RESUMO

BACKGROUND: This study was performed to identify and compare the presence of and the levels of post-traumatic stress disorder (PTSD), anxiety, depression and if any change in sexual functioning is present in patients with disfiguring facial injuries, nondisfiguring facial injuries and visible extremity injuries. MATERIALS AND METHODS: A total of 378 patients from multi modal trauma centers in Bengaluru city were included for the study. A total of 153 patients were those who had disfiguring facial injuries, 111 patients with nondisfiguring facial injuries and 114 patients had sustained a visible extremity injury that was not covered by clothing (disfigurement /scarring). The assessments were carried out at three time intervals (the date of discharge, 1 month postoperatively and 6 months postoperatively) of the follow-up. The impact of events scale (IES), the hospital anxiety and depression scale (HADS) and changes in sexual functioning questionnaire (CSFQ) were used. RESULTS: Statistically significant higher means of IES, HADS (both for anxiety and depression) were present in patients with disfiguring facial injuries compared to patients with nondisfiguring facial injuries and visible extremity injuries and this was present at all three study intervals (date of discharge,1 st postoperative month and 6th postoperative month). There was a statistically significant change in the means of CSFQ scores of visible extremity injuries compared to other groups at the date of discharge bordering on sexual dysfunction, there was a raise in CSFQ scores among all three groups at the 1st postoperative month and the 6th postoperative month which was above the dysfunction cut-off. CONCLUSION: The results of this study led to the conclusion that in comparison with patients who had sustained disfiguring facial injuries, nondisfiguring facial injuries and visible extremity/ orthopedic injuries, the mean IES scores, HADS scores for both anxiety and depression of the facial disfiguring injury patients was higher at all three study intervals (date of discharge,1st postoperative month and 6 months postoperatively), indicating higher PTSD levels, anxiety and depression in patients with disfiguring facial injuries, CSFQ scores were above the cutoff suggested at the 1st month and 6th month postoperative indicating no sexual dysfunction in all the three groups.

RESUMO

AIMS: Biofilm formation and polycyclic aromatic hydrocarbons (PAHs) degradation by a marine bacterium Stenotrophomonas acidaminihila NCW-702 was investigated. METHODS AND RESULTS: The biofilm structure was studied by confocal laser scanning microscopy (CLSM). Both planktonic and biofilm cultures were used for PAHs (phenanthrene and pyrene) degradation. In 7 days, Sten. acidaminiphila biofilm culture efficiently degraded 71·1 ± 3·1% and 40·2 ± 2·4% of phenanthrene and pyrene, respectively, whereas 38·7 ± 2·5% of phenanthrene and 29·7 ± 1% of pyrene degradation was observed in planktonic culture. The presence of phenolic intermediates in the culture supernatant during degradation process was evaluated by Folin-Ciocalteu reagent. The average thickness and diffusion distance of Sten. acidaminiphila NCW-702 biofilm was found to be 23·94 ± 2·62 µm and 2·68 ± 0·7 µm, respectively. Bacterial biofilms have numerous metabolic features that aid in the degradation of hydrophobic organic pollutants. CONCLUSIONS: Biofilm of Sten. acidaminiphila NCW-702 was able to degrade PAHs more efficiently as compared to planktonic cells. The findings support the efficacy of biofilms over planktonic culture in bioremediation applications. SIGNIFICANCE AND IMPACT OF THE STUDY: The study provides a constructive application of bacterial biofilms for the bioremediation of hydrophobic organic contaminants. The biofilm mode remediation process has the advantage of reusability of bacterial biomass and is also a low cost process as compared to cell immobilization techniques.

RESUMO

Biofilm-forming marine bacterium Paenibacillus lautus NE3B01 was isolated from a mangrove ecosystem, Odisha, India. This isolate formed a swarming type of colony pattern on the solid culture medium with 0.5-2 % agar. Phase contrast microscopy study of a growing colony of P. lautus on solid media and swarming pattern revealed the existence of two phenotypically distinct cells (i.e. cocci and rods) across the colonies. However, in actively growing planktonic culture, only rod-shaped cells were observed. Biofilm growth studies (crystal violet assay) with the isolate showed significant biofilm formation by 6 h, and the detachment phase was observed after 18 h. Biofilm parameters (such as total biomass, roughness coefficient, biofilm thickness, etc.) of 24-h-old P. lautus biofilm were studied by confocal scanning laser microscopy (CSLM). The CSLM study showed that P. lautus formed a biofilm with an average thickness of 14.8 ± 2.6 µm, a high roughness coefficient (0.379 ± 0.103) and surface to bio-volume ratio (4.59 ± 1.12 µm(2)/µm(3)), indicating a highly uneven topography of the biofilm. This also indicates that the 24-h-old biofilm is in dispersal phase. Scanning electron microphotographs of P. lautus also supported the existence of two distinct phenotypes of P. lautus. The current findings suggest that P. lautus has two vegetative phenotypes and to decongest the overcrowded biofilm the bacterium can switch over to motile rods from nonmotile cocci and vice versa.

RESUMO

There is increasing concern among both healthcare professionals and the general public about the long-term effectiveness and possible adverse effects of medicines used to treat premature ejaculation (PE) and erectile dysfunction (ED). There is also a growing recognition of the advantages of incorporating alternative or traditional approaches into healthcare systems. Yoga is gaining popularity globally and has emerged as a viable adjunct and alternative to add value to patient care and prevention of illnesses, which requires further investigation. This scoping review aimed to explore the effects of yoga as an independent or adjunct intervention in treating ED and PE. In this review study, researchers conducted a systematic literature review from 2000 to 2023 as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic databases of Scopus, Google Scholar, Web of Science, and PubMed were used for literature searches. Studies published in the English language on male individuals with ED and PE and those with comorbid stress, anxiety, and depression were also included. Studies on these sexual dysfunctions, comorbid with HIV/AIDS, and severe psychiatric conditions, i.e., schizophrenia, bipolar affective disorders, and substance dependence, except alcohol, were excluded. Ten studies out of the 2016 selected articles met the inclusion criteria and were included in the final analysis. The findings of this scoping review revealed that yoga interventions are more effective in managing PE and ED, with a greater emphasis on the former. Yoga is an effective, safe, and affordable approach recommended for managing erectile functions and PE. Men can improve their quality of life and regain confidence in sexual functioning by incorporating yoga into their routines. The study shows the potential benefits of yoga for both conditions, indicating the need for further robust studies in this area. Researchers advocate practising yoga under professional supervision for optimal safety and guidance.

RESUMO

Background: Depression among people living with human immunodeficiency virus (PLHIV) is highly prevalent and it is associated with increased morbidity, poor adherence to antiretroviral therapy, and poor psychosocial outcomes. To address this, integrated counselling and testing centres (ICTC) counsellors provide psychosocial support to PLHIV. Materials and Methods: This descriptive study aims to assess the awareness and knowledge of ICTC counsellors about depression and its management. A total of 338 (n = 452) ICTC counsellors participated in the study. A demographic data sheet and a semi-structured questionnaire were used to collect data. Results: More than half of the participants reported that biochemical imbalances cause depression. 71.60% and 79.59% of participants reported that depression was common among PLHIV and required immediate attention. 92.60% of counsellors reported that a combination of counselling and medication would be effective to treat depression. 86.98% and 81.95% of counsellors were confident and actively screened for depression among PLHIV, and 78.11% of counsellors had access to a psychiatrist. In contrast. One-third of participants had difficulties working with PLHIV, and 55.56% of participants expressed that addressing issues of PLHIVs' depression to be left to mental health professionals. Conclusion: ICTC counsellors had adequate knowledge about depression and its symptoms. However, lack of knowledge on intervention strategies, time constraints and work targets are significant barriers. These findings suggest that training on mental illness screening; brief intervention strategies may help counsellors to assist PLHIV in overcoming depression complications.

RESUMO

We have developed the first total syntheses of marine natural products ma'edamines A (18) and B (20). Structurally, they contain a pyrazine-2-(1H)-one core and were screened for antiproliferative activity on several cancer cell lines. Out of the six cell lines tested, ma'edamines A and B showed significant cytotoxicity against human colon cancer line COLO 205 (IC(50) 7.9 and 10.3 µM, respectively), breast cancer cell line MCF-7 (IC(50): 6.9 and 10.5 µM, respectively) and human lung adenocarcinoma cell line A549 (IC(50): 12.2 and 15.4 µM, respectively). The apoptotic effect of ma'edamines was confirmed by comet assay. Hence ma'edamines are likely to be useful as leads for development of a new class of anti-cancer agents.

RESUMO

Background: Sexual dysfunction among female psychiatric patients is zcommon and can be affected by various bio-psycho-social factors. The clinician's or patient's reluctance to actively inquire or spontaneously report these sexual difficulties creates a lacuna in our understanding of this association. This study aimed to assess the proportion of women with nonpsychotic psychiatric disorders reporting sexual dysfunction and evaluate its association with sociodemographic and clinical variables. Methods: This cross-sectional study conducted over six months included 113 women attending the psychiatry outpatient department of a tertiary care hospital. Sociodemographic and clinical variables, including diagnosis based on International Classification of Diseases 10th version (ICD 10) criteria, were assessed using a specially designed proforma. Sexual functioning was measured by Female Sexual Functioning Index (FSFI) and the Change in Sexual Functioning Questionnaire-Female Version (CSFQ-FV). Results: Sexual dysfunction was reported by 67.3% of patients. Among patients on psychotropics, 49% reported worsening of sexual dysfunction after treatment initiation. Sexual dysfunction was associated with increasing age (χ2 = 7.86, P = 0.04), lower educational qualification (χ2 =3.41, P = 0.04), skilled occupation (χ2 = 4.49, P = 0.03), lower socioeconomic status (χ2 = 4.27, P = 0.03) and presence of ongoing psychosocial stressor (χ2 = 4.49, P = 0.03). Conclusions: Difficulties in different domains of sexual functioning are prevalent among women with nonpsychotic disorders. Sociodemographic and relational factors, along with treatment status, can influence sexual dysfunction in these patients. Clinicians should be vigilant of this association and should plan treatment to enhance compliance and outcome.

RESUMO

Surgeons treating advanced carcinoma of the tongue with total glossectomy face many conflicts in view of the morbidity and poor functional and survival outcomes following surgery. It is pertinent to study the patients undergoing total tongue compartment resection as a separate cohort to analyse their outcomes. This study investigated the oncological outcomes of 150 patients with advanced tongue squamous cell carcinoma who underwent total glossectomy. The results suggest that compartment resection significantly improved local control, irrespective of margin status. The presence of multiple positive nodes was found to be an independent poor prognostic factor, and adjuvant radiation significantly improved survival. Total glossectomy is feasible and safe in both the primary and salvage setting and should be considered as the surgical option for advanced tongue cancer.

RESUMO

Culture and molecular-based techniques were used to characterize bacterial diversity in the cooling water system of a fast breeder test reactor (FBTR). Techniques were selected for special emphasis on sulphate-reducing bacteria (SRB). Water samples from different locations of the FBTR cooling water system, in addition to biofilm scrapings from carbon steel coupons and a control SRB sample were characterized. Whole genome extraction of the water samples and SRB diversity by group specific primers were analysed using nested PCR and denaturing gradient gel electrophoresis (DGGE). The results of the bacterial assay in the cooling water showed that the total culturable bacteria (TCB) ranged from 10(3) to 10(5) cfu ml(-1); iron-reducing bacteria, 10(3) to 10(5) cfu ml(-1); iron oxidizing bacteria, 10(2) to 10(3) cfu ml(-1) and SRB, 2-29 cfu ml(-1). However, the counts of the various bacterial types in the biofilm sample were 2-3 orders of magnitude higher. SRB diversity by the nested PCR-DGGE approach showed the presence of groups 1, 5 and 6 in the FBTR cooling water system; however, groups 2, 3 and 4 were not detected. The study demonstrated that the PCR protocol influenced the results of the diversity analysis. The paper further discusses the microbiota of the cooling water system and its relevance in biofouling.

RESUMO

An unique case of dense fouling by an acidophilic, hard rubber (polymerized rubber) degrading fungus in the acid transfer pipelines of a boron enrichment plant located at Kalpakkam, India is reported. In spite of a highly adverse environment for survival (pH 1.5, no dissolved nutrients), the fungus thrived and clogged the pipeline used for transferring 0.1N hydrochloric acid (HCl). Detailed investigations were carried out to isolate and identify the fungus and examine the nutrient source for such profuse growth inside the system. Microscopic observation showed the presence of a thick filamentous fungal biomass. Molecular characterization by 18S rRNA gene sequencing showed 98% similarity of the isolate with the acidophilic fungus Bispora sp. In laboratory studies the fungus showed luxuriant growth (specific growth rate of 13 mg day⁻¹) when scrapings of the hard rubber were used as the sole source of carbon. Scanning electron microscopy revealed extensive incursion of the fungus into the hard rubber matrix. In the laboratory, fungal growth was completely inhibited by the antifungal agent sodium omadine. The study illustrates an interesting example of biofouling under extreme conditions and demonstrates that organisms can physiologically adapt to grow under unfavourable conditions, provided that a nutrient source is available and competition is low. The use of this fungal strain in biodegradation and in development of environmentally compatible processes for disposal of rubber wastes is envisaged.

RESUMO

Sexual health, an essential component of individual's health, is influenced by many complex issues including sexual behavior, attitudes, societal, and cultural factors on the one hand and while on the other hand, biological aspects, genetic predisposition, and associated mental and physical illnesses. Sexual health is a neglected area, even though it influences mortality, morbidity, and disability. Dhat syndrome (DS), the term coined by Dr. N. N. Wig, has been at the forefront of advancements in understanding and misunderstanding. The concept of DS is still evolving being treated as a culture-bound syndrome in the past to a syndrome of depression and treated as "a culturally determined idiom of distress." It is bound with myths, fallacies, prejudices, secrecy, exaggeration, and value-laden judgments. Although it has been reported from many countries, much of the literature has emanated from Asia, that too mainly from India. The research in India has ranged from the study of a few cases in the past to recent national multicentric studies concerning phenomenology and beliefs of patients. The epidemiological studies have ranged from being hospital-based to population-based studies in rural and urban settings. There are studies on the management of individual cases by resolving sexual myths, relaxation exercises, supportive psychotherapy, anxiolytics, and antidepressants to broader and deeper research concerning cognitive behavior therapy. The presentation looks into DS as a model case highlighting the importance of exploring sexual health concerns in the Indian population in general and in particular need to reconsider DS in the light of the newly available literature. It makes a fervent appeal for the inclusion of DS in the mainstream diagnostic categories in the upcoming revisions of the diagnostic manuals which can pave the way for a better understanding and management of DS and sexual problems.

RESUMO

INTRODUCTION: Frontline healthcare workers (HCW) have faced significant plight during the ongoing Coronavirus disease 2019 (COVID-19) pandemic. Studies have shown their vulnerabilities to depression, anxiety disorders, post-traumatic stress, and insomnia. In a developing country like India, with a rising caseload, resource limitations, and stigma, the adversities faced by the physicians are more significant. We attempted to hear their "voices" to understand their adversities and conceptualize their resilience framework. METHODS: A qualitative approach was used with a constructivist paradigm. After an initial pilot, a socio-demographically heterogeneous population of 172 physicians working in COVID-designated centers were purposively sampled from all over India. Following in-depth virtual interviews using a pre-formed semi-structured guide, the data was transcribed and translated verbatim. The interview was focused on their challenges, needs, and processes of coping and support. Charmaz's grounded theory was used for analysis supplemented by NVivo 10 software. RESULTS: Fear of infection, uncertainty, stigma, guilt, and social isolation emerged as the main challenges. Simultaneously, their "unmet needs" were flexible work policies, administrative measures for better medical protection, the sensitivity of media toward the image of HCW, effective risk communication for their health, and finally, social inclusion. Their resilience "framework" emerged as a process while navigating these adversities and consisted of three facets: forming a "resilient identity," managing the resilience, and working through the socio-occupational distress. The role of mental well-being, social network, peer support, problem negotiation, and self-care emerged as the key coping strategies. CONCLUSION: The study findings support the global call for better psychosocial health and quality of life of the frontline HCWs. Their "unheard voices" explored in the study can anchor subsequent resilience-enhancing interventions and policies. Guidelines focusing on the psychological wellbeing of frontline HCWs need to be grounded in their unmet needs and lived experiences.

RESUMO

The Coronavirus disease 2019 (COVID-19) has emerged as a new global health threat. By increasing the risk of isolation, fear, stigma, abuse and economic fallout, COVID-19 has led to increase in risk of psychiatric disorders, chronic trauma and stress, which eventually increase suicidality and suicidal behavior. There is limited data on association of pandemics and suicides. Cases of suicides have been rising since COVID-19 first emerged in China. The association between suicides and pandemics can possibly be explained through various models like Durkheim's theory, Joiner's interpersonal theory, social stress theory, biological theories, etc. The frontline workers, elderly, migrants, homeless, socio-economically impoverished classes as well as those with pre-existing mental disorders, substance abuse and family history of suicides are at higher risk. Suicides are preventable and need early detection, awareness and socio-culturally tailored interventions. This narrative review draws global perspectives on the association of suicidality and pandemics, the theories and risk factors related to same based on the available evidence. It also hypothesizes neuroimmunity and immune based risk factors as possible links between the psychosocial vulnerabilities and suicide during outbreaks like COVID-19. Proposed strategies of suicide-prevention, as an integral part of public health response to the pandemic are subsequently discussed.

RESUMO

BACKGROUND: The global prevalence of stress is increasing. Stress adversely affects cognitive ability, sleep quality, and overall psychological well-being. Ashwagandha (Withania somnifera (L.) Dunal), an essential medicine in Ayurveda, is reportedly beneficial in reducing stress and improving memory. This double-blind, randomized, placebo-controlled clinical study evaluated the effect of Ashwagandha root extract sustained-release capsule 300 mg (Prolanza™; hereafter Ashwagandha SR) on cognitive functions, stress levels, sleep quality, overall well-being, and safety in stressed subjects. METHODS: Subjects (130 healthy cognitively sound adults [20-55 years, body mass index:18-29 kg/m2]) having a Perceived Stress Scale (PSS) score of 14-24 were randomized to receive either Ashwagandha SR or placebo. Subjects took one capsule of Ashwagandha SR or placebo daily for 90 consecutive days. This study was registered on Clinical Trials Registry-India (CTRI) on 13/11/2019 [number: CTRI/2019/11/021990]. The primary endpoint was the change in cognitive function as measured by CANTAB from baseline to the end of the study period (90 ± 7 days). The secondary outcomes included the change in PSS-10 score, serum cortisol level (9-11 am), the OHQ score, the PSQI, and serum BDNF levels. RESULTS: Only 125 completed the study and were evaluated. The Cambridge Neuropsychological Test Automated Battery (CANTAB) reported significantly improved recall memory, and the total error rate in recalling patterns significantly decreased at visit 4 in the Ashwagandha SR group vs. the placebo group (first attempt memory score:12.9 ± 6.7 vs. 10.1 ± 6.3; total errors:17.5 ± 23.3 vs. 27.7 ± 23.6). At visit 4, lower PSS-10 score (13.0 ± 5.0 vs. 18.7 ± 4.6; p < .0001), serum cortisol levels (p=0.0443), and Pittsburgh Sleep Quality Index (PSQI) score (p < .0001) but higher Oxford Happiness Questionnaire (OHQ) scores (p < .0001) were seen in Ashwagandha SR vs. the placebo group, suggesting significantly lower stress levels and significantly better psychological well-being and sleep quality in the former. No adverse events were reported. CONCLUSIONS: This is the first clinical study assessing Ashwagandha SR for its safety and efficacy. Treatment with one Ashwagandha SR capsule once daily for 90 days improved memory and focus, psychological well-being, and sleep quality, reduced stress levels, and was safe and well-tolerated.
