RESUMO

BACKGROUND: The therapeutic landscape in medical oncology continues to expand significantly. Newer therapies, especially immunotherapy, offer the hope of profound and durable responses with more tolerable side effect profiles. Integrating this information into the decision making process is challenging for patients and oncologists. Systemic anticancer treatment within the last thirty days of life is a key quality of care indicator and is one parameter used in the assessment of aggressiveness of care. METHODS: A retrospective review of medical records of all patients previously treated at Goulburn Valley Health oncology department who died between 1 January 2015 and 30 June 2018 was conducted. Information collected related to patient demographics, diagnosis, treatment, and hospital care within the last 30 days of life. These results were presented to the cancer services meeting and a quality improvement intervention program was instituted. A second retrospective review of medical records of all patients who died between 1 July 2018 and 31 December 2018 was conducted in order to measure the effect of this intervention. RESULTS: The initial audit period comprised 440 patients. 120 patients (27%) received treatment within the last 30 days of life. The re-audit period comprised 75 patients. 19 patients (25%) received treatment within the last 30 days of life. Treatment rates of chemotherapy reduced after the intervention in contrast to treatment rates of immunotherapy which increased. A separate analysis calculated the rate of mortality within 30 days of chemotherapy from the total number of patients who received chemotherapy was initially 8% and 2% in the re-audit period. Treatment within the last 30 days of life was associated with higher use of aggressive care such as emergency department presentation, hospitalisation, ICU admission and late hospice referral. Palliative care referral rates improved after the intervention. CONCLUSION: This audit demonstrated that a quality improvement intervention can impact quality of care indicators with reductions in the use of chemotherapy within the last 30 days of life. However, immunotherapy use increased which may be explained by increased access and a better risk benefit balance.

RESUMO

This study quantifies sex differences in the diurnal and circadian variation of sleep and waking while controlling for menstrual cycle phase and hormonal contraceptive use. We compared the diurnal and circadian variation of sleep and alertness of 8 women studied during two phases of the menstrual cycle and 3 women studied during their midfollicular phase with that of 15 men. Participants underwent an ultradian sleep-wake cycle (USW) procedure consisting of 36 cycles of 60-min wake episodes alternating with 60-min nap opportunities. Core body temperature (CBT), salivary melatonin, subjective alertness, and polysomnographically recorded sleep were measured throughout this procedure. All analyzed measures showed a significant diurnal and circadian variation throughout the USW procedure. Compared with men, women demonstrated a significant phase advance of the CBT but not melatonin rhythms, as well as an advance in the diurnal and circadian variation of sleep measures and subjective alertness. Furthermore, women experienced an increased amplitude of the diurnal and circadian variation of alertness, mainly due to a larger decline in the nocturnal nadir. Our results indicate that women are likely initiating sleep at a later circadian phase than men, which may be one factor contributing to the increased susceptibility to sleep disturbances reported in women. Lower nighttime alertness is also observed, suggesting a physiological basis for a greater susceptibility to maladaptation to night shift work in women.

RESUMO

This study of depressed outpatients (N = 43) examined daily stress-sadness reactivity and the cortisol awakening response (CAR) as moderators of the relationship between self-critical (SC) perfectionism and depression over one year. Participants completed perfectionism measures at baseline (Time 1), daily diaries and salivary sampling six months later (Time 2), and an interviewer-rated depression measure at Time 1, Time 2, and one year after baseline (Time 3). Hierarchical multiple regression analyses of moderator effects demonstrated that patients with higher SC perfectionism and higher levels of daily stress-sadness reactivity (i.e., greater increases in daily sadness in response to increases in daily stress) had less improvement in depressive symptoms at Time 3 relative to those of other patients, adjusting for the effects of Time 1 and Time 2 depression. Furthermore, higher SC perfectionism in conjunction with an elevated CAR predicted higher levels of depression at Time 3. In addition, lower SC perfectionism in combination with higher levels of stress-sadness reactivity/CAR was associated with the lowest levels of depression at Time 3. These findings highlight the importance of targeting dysfunctional self-critical characteristics that exacerbate the impact of heightened stress-sadness reactivity and CAR to generate better treatment outcomes for patients with higher SC perfectionism.

RESUMO

To evaluate the achievement of treat-to-target (T2T) strategy in rheumatoid arthritis (RA) and identify factors associated with failed treatment target in a public rheumatology center. A cross-sectional study was conducted from June 2015 to February 2016. RA patients with disease duration greater than 2 years and under T2T for over a year were invited to the study. Demographic, clinical data, disease activity score of 28 joints (DAS28), and clinical disease activity index (CDAI) were collected in a single routine clinic visit. Treatment target was defined as DAS28 <3.2 or CDAI ≤10. Retrospective chart review was performed to determine reasons of failed treatment target. A total of 371 patients were recruited and 87.1% were female. Mean age and duration of RA were 53.5 years (SD 10.3) and 9.1 years (SD 6.6), respectively. Ethnic distribution was 49% Chinese, 27% Malay, and 24% Indian. T2T was achieved in 81.7% of the cohort. Non-Chinese ethnicity, positive rheumatoid factor, and treatment with three disease modifying anti-rheumatic drugs (DMARDs) were associated with failed treatment target. After controlling for covariates, Malay ethnicity (OR 2.96; 95% CI 1.47-5.96) and treatment with three DMARDs (OR 2.14; 95% CI 1.06-4.35) were associated with failed treatment target. There was no association between age, gender, duration of RA, BMI, smoking status, anti-citrulinated cyclic peptide, and achievement of T2T. The most common reasons of failed treatment target were inability to escalate DMARDs due to side effects (18.8%), lack of biologics fund (15.6%), and persistent disease despite optimum treatment (14.1%). T2T was successfully implemented. Malay patients need aggressive treatment adaptation to achieve optimal outcome.

RESUMO

Volvaria volvacea (Bull. ex Fr.) Sing, an important edible and medicinal macro-fungus, has been used to remedy various diseases for hundreds of years in East Asia. To identify key proteins with the unique therapeutic activity in V. volvacea, we conducted a genomewide comparison of V. volvacea protein families and those of other edible fungi that lack therapeutic functions and identified seven fungal immunomodulatory proteins (FIPs) in V. volvacea. On the basis of the predicted physiological and biochemical characteristics of the seven FIPs, the novel Fip-vvo82 was inferred to have high immunomodulatory activity; this was confirmed by molecular and immunological experiments and further characterized by modeling the three-dimensional structure and protein-protein docking. This is the first study to show that V. volvacea has more than one FIP.

RESUMO

BACKGROUND: Adenocarcinomas of both the gastroesophageal junction and stomach are molecularly complex, but differ with respect to epidemiology, etiology and survival. There are few data directly comparing the frequencies of single nucleotide mutations in cancer-related genes between the two sites. Sequencing of targeted gene panels may be useful in uncovering multiple genomic aberrations using a single test. METHODS: DNA from 92 gastroesophageal junction and 75 gastric adenocarcinoma resection specimens was extracted from formalin-fixed paraffin-embedded tissue. Targeted deep sequencing of 46 cancer-related genes was performed through emulsion PCR followed by semiconductor-based sequencing. Gastroesophageal junction and gastric carcinomas were contrasted with respect to mutational profiles, immunohistochemistry and in situ hybridization, as well as corresponding clinicopathologic data. RESULTS: Gastroesophageal junction carcinomas were associated with younger age, more frequent intestinal-type histology, more frequent p53 overexpression, and worse disease-free survival on multivariable analysis. Among all cases, 145 mutations were detected in 31 genes. TP53 mutations were the most common abnormality detected, and were more common in gastroesophageal junction carcinomas (42% vs. 27%, p = 0.036). Mutations in the Wnt pathway components APC and CTNNB1 were more common among gastric carcinomas (16% vs. 3%, p = 0.006), and gastric carcinomas were more likely to have ≥3 driver mutations detected (11% vs. 2%, p = 0.044). Twenty percent of cases had potentially actionable mutations identified. R132H and R132C missense mutations in the IDH1 gene were observed, and are the first reported mutations of their kind in gastric carcinoma. CONCLUSIONS: Panel sequencing of routine pathology material can yield mutational information on several driver genes, including some for which targeted therapies are available. Differing rates of mutations and clinicopathologic differences support a distinction between adenocarcinomas that arise in the gastroesophageal junction and those that arise in the stomach proper.

RESUMO

Inspired by tea stains, plant polyphenolic tannic acid (TA) was beneficially employed as the primer anchor for functional polymer brushes. The brominated TA (TABr) initiator primer was synthesized by partial modification of TA with alkyl bromide functionalities. TABr with trihydroxyphenyl moieties can readily anchor on a wide range of substrates, including metal, metal oxide, polymer, glass, and silicon. Concomitantly, the alkyl bromide terminals serve as initiation sites for atom transfer radical polymerization (ATRP). Cationic [2-(methacryloyloxy)ethyl]trimethylammonium chloride (META) and zwitterionic 2-methacryloyloxyethyl phosphorylcholine (MPC) and N-(3-sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine (SBMA) were graft-polymerized from the TABr-anchored stainless steel (SS) surface. The cationic polymer brushes on the modified surfaces are bactericidal, while the zwitterionic coatings exhibit resistance against bacterial adhesion. In addition, microalgal attachment (microfouling) and barnacle cyprid settlement (macrofouling) on the functional polymer-grafted surfaces were significantly reduced, in comparison to the pristine SS surface. Thus, the bifunctional TABr initiator primer provides a unique surface anchor for the preparation of functional polymer brushes for inhibiting both microfouling and macrofouling.

RESUMO

Minilaparoscopy is an attractive approach for hysterectomy due to advantages such as reduced morbidities and enhanced cosmesis. However, it has not been popularized due to the lack of suitable instruments and high technical demand. We aim to highlight the first case of minilaparoscopic hysterectomy reported in Asia and the use of a new integrated energy platform, Thunderbeat. We would like to propose an alternative method of instrumentation, so as to improve the feasibility and safety of minilaparoscopic hysterectomy. The first minilaparoscopic hysterectomy in Singapore was successfully completed using the alternative instrumentation and new energy platform. There was no conversion or complication during the surgery. The patient recovered uneventfully. To our knowledge, this is the first report on the use of such alternative instrumentation. This approach in instrumentation and the new energy platform will improve the feasibility and speed of the surgery and ensure safety in our patients.

RESUMO

Monkeypox is known to be endemic in Africa, but recently, the unusually increasing number of cases of monkeypox in non-endemic countries has caught the attention of the world. The World Health Organization has declared the monkeypox outbreak a public health emergency. The spread pattern is unlikely associated with the previous outbreak outside of Africa, which is related to travelling or contact with exotic animals. The current outbreak is linked to sexual history and presents with atypical localised genital eruptions with an unpredictable onset of viral prodromal symptoms. Although the monkeypox virus is not easily transmittable compared with severe acute respiratory syndrome coronavirus 2, anyone who has been in close contact with a patient with monkeypox is at risk. Most patients will present to a primary care centre for assessment and treatment; therefore, it is important to increase awareness of the infection among primary care providers for early recognition of monkeypox, containment of the outbreak and prevention of healthcare-associated infection. A physician who suspects any patient with monkeypox should notify local or state health authorities immediately.

RESUMO

Female sexual dysfunction (FSD) is a common problem among postpartum women. However, little is known about this topic in Malaysia. This study aimed to determine the prevalence of sexual dysfunction and its associated factors in postpartum women in Kelantan, Malaysia. In this cross-sectional study, we recruited 452 sexually active women at six months postpartum from four primary care clinics in Kota Bharu, Kelantan, Malaysia. The participants were asked to fill in questionnaires consisting of sociodemographic information and the Malay Version of the Female Sexual Function Index-6. The data were analyzed using bivariate and multivariate logistic regression analyses. With a 95% response rate, the prevalence of sexual dysfunction among sexually active, six months postpartum women was 52.4% (n = 225). FSD was significantly associated with the older husband's age (p = 0.034) and lower frequency of sexual intercourse (p<0.001). Therefore, the prevalence of postpartum sexual dysfunction in women is relatively high in Kota Bharu, Kelantan, Malaysia. Efforts should be made to raise awareness among healthcare providers about screening for FSD in postpartum women and for their counseling and early treatment.

RESUMO

The Postnatal Depression Intervention Program is a screening program looking at postnatal depression in newly delivered mothers at KK Hospital in Singapore. The primary objective of the paper is to evaluate the outcomes based on changes in scores from baseline to end of intervention with reference to depressive symptoms, using the Edinburgh Postnatal Depression Scale and overall functioning based on the Global Assessment of Functioning. These changes were found to be statistically significant. We also described the demographics of the 10-year cohort with majority being married, Chinese, aged between 25 and 34 years old and received at least tertiary education.

RESUMO

BACKGROUND: Colorectal neoplasia is a multistep process that can lead to the development of colorectal cancer. Colonoscopy is the gold standard for diagnosis and screening of colorectal cancer, but its uptake is often hindered by unpleasant experiences and logistic obstacles. Therefore, non-invasive biomarker tests such as the M2-pyruvate kinase (M2PK) test have been explored as a potential screening tool. OBJECTIVE: This study aims to evaluate the efficacy of the M2PK Quick Stool Test (ScheBo®) in detecting colorectal adenoma and adenocarcinoma in high-risk Malaysian populations using colonoscopy as the comparison. METHODS: A prospective, cross-sectional, multicenter study was conducted from December 2017 to December 2019 in four hospitals in Malaysia. Participants were eligible if they met any of the following criteria: personal or family history of colorectal polyps or cancer, inherited syndromes, altered bowel habits, rectal bleeding, unintended weight loss, loss of appetite, abdominal pain or cramps, or unexplained iron deficiency, or an Asia-Pacific Colorectal Screening score of 4-7. Participants provided a stool sample that was tested for M2PK using the M2PK Quick Test. Participants then underwent a colonoscopy, and any lesions found were biopsied and sent for histopathological examination. RESULTS: A total of 562 participants were included in the study, of whom 89 had a positive M2PK test. Presence of adenoma and/or dysplastic lesions were confirmed in 14.4% and adenocarcinoma in 3.0% of the participants. The M2PK Quick Stool Test showed a sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 58.8%, 85.5%, 11.2% and 98.5%, respectively in detecting colorectal adenocarcinoma. For detection of colorectal adenoma, this test yielded a sensitivity, specificity, PPV and NPV of 27.3%, 86.3%, 27.0% and 86.5%, respectively. CONCLUSIONS: The M2PK Quick Stool Test showed a moderate accuracy in detecting colorectal adenocarcinoma and adenomas in the studied population.

RESUMO

Postpartum depression (PPD) is a public health problem that is associated with detrimental effects on the wellbeing of the mother, child and family. Early detection for PPD at the primary health level provides an opportunity for intervention. We aim to examine: (1) the prevalence rate of PPD in the primary care population, (2) acceptance and attendance rates of intervention for women who screened positive for PPD, (3) sociodemographic and maternal risk factors of PPD, and (4) the impact of PPD on breastfeeding. We implemented a mother-child dyadic screening program using the modified Patient Health Questionnaire-2 during routine well-child visits at 2 or 3 months postpartum between July 2019 and December 2021. We performed multivariable logistic regression to identify independent risk factors for PPD and described using adjusted odds ratio (OR) with corresponding 95 % confidence intervals. Among 5561 mothers, the prevalence rate of probable PPD was 2.4 %. About half (54.4 %) of mothers who screened positive accepted intervention and of these, about two-thirds accepted onward referrals to tertiary care and community mental health service, with higher attendance at the latter. In the final adjusted model, mothers who had probable PPD were more likely to be older than age 35 years (OR 1.88, 95 % CI 1.05-3.45; p < 0.05) and not breastfeeding (OR 1.9, 95 % CI 1.06-3.38; p < 0.05). Overall, our findings highlight the importance of early PPD screening and management in primary care. These findings can help inform maternal mental health service development and utilization, thereby optimizing maternal and infant outcomes.

RESUMO

Introduction: Perinatal depression and anxiety are public health concerns affecting approximately 1 in 10 women in Singapore, with clear evidence of association with various adverse outcomes in mother and child, including low birthweight, preterm birth and negative impact on infant neurodevelopment, temperament and behaviour. A workgroup was formed to develop recommendations to address the perinatal mental health needs of women with depression and anxiety. The approach was broad-based and aimed to incorporate holistic methods that would be readily applicable to the network of care providers supporting childbearing women. Method: The Grading and Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision framework was employed to draw these guidelines. Workgroup members-comprising experts in the field of perinatal mental health and obstetric medicine-deliberated on the public health needs of the target population, and reviewed literature published from 2001 to 2022 that were relevant to improve the well-being of women with depression and anxiety during the preconception and perinatal periods. Results: A consensus meeting was held involving a wider professional network, including family physicians, paediatricians, psychiatrists, social services and the Health Promotion Board in Singapore. Conclusion: Ten consensus statements were developed, focusing on the overall aim of achieving optimal perinatal mental health for women with depression and anxiety. They relate to awareness and advice on preconception mental health, screening and assessment, optimising care and treatment. Special considerations were recommended for women who suffered severe maternal events, tailoring care for adolescents and women with special needs, and addressing infant mental health needs.

RESUMO

Although the extraction and analysis of nucleic acids from formalin-fixed paraffin-embedded tissues is a routine and growing part of pathology practice, no generally accepted recommendations exist to guide laboratories in their selection of tissue fixation, processing and DNA/RNA extraction techniques. The aim of this study was to determine how fixation method and length, paraffin embedding, processing conditions and nucleic acid extraction methods affect quality and quantity of DNA and RNA, and their performance in downstream applications. Nine tissue samples were subjected to freezing, fixation in formalin for <24 h and 7 days followed by conventional processing, and fixation in molecular fixative for <24 h and 7 days followed by rapid processing. DNA and RNA were isolated using in-house extraction and commercial kits, and assessed by PCR reactions for amplicons with varying sizes ranging from 268 to 1327 bp and one-step RT-PCR for 621 bp and 816 bp amplicons of housekeeping genes. Molecular fixative (MF) appeared to perform well under nearly all circumstances (extraction methods, fixation lengths and longer amplicons), often performing as well as frozen samples. Formalin fixation generally performed well only for shorter length amplicons and short fixation (<24 h). WaxFree kit showed consistently higher success rates for DNA and poorer rates for RNA. RecoverAll kit generally performed suboptimally in combination with prolonged formalin fixation. In conclusion, the Molecular Fixative regardless of fixation length, and the rapid tissue processing system were able to preserve large DNA and RNA fragments in paraffin blocks, making these techniques preferable for use in downstream molecular diagnostic assays.

RESUMO

While the assessment of higher education systems is informative to both policy makers and individuals, it is subjective and performed according to experts' judgment. The present study proposes a relatively objective approach, hierarchical data envelopment analysis (H-DEA), to rank higher education systems. Unlike the subjective approach, H-DEA utilizes endogenous weight determination, allowing assessors to identify the relative importance of each attribute and subattribute. Utilizing the U21 Ranking of National Higher Education System 2020 data, our analysis indicates that the output attribute is a crucial factor influencing the overall performance of higher education systems, even considering countries' stage of development and culture. The computed weights of the H-DEA framework show various attributes' different contributions by group. Resources allocated to the higher education system are important for developing countries, while a high degree of internationalization and a strong link between academia and industry matter for advanced countries. Surprisingly, Asian and Western cultures experience similar performance in their higher education systems, reflecting the Asian higher education system's development toward the Western style. The performance of countries with non-Asian-non-Western cultures, as expected, lags behind, and putting more resources into these countries' higher education system is a way to enhance the overall performance.

RESUMO

Paroxetine binding could be a vulnerability marker for traits associated with borderline personality disorder (BPD). To study this relationship, we examined [³H] paroxetine binding in female patients with BPD and their sisters. The sample consisted of 54 sibling pairs in which a proband met criteria for BPD. All subjects were given the Diagnostic Interview for Borderlines, revised (DIB-R), the Diagnostic Assessment for Personality Pathology: Brief Questionnaire (DAPP-BQ), the Barratt Impulsivity Scale (BIS), the Affective Lability Scale (ALS), the Hamilton Rating Scale for Anxiety (HAM-A), the Hamilton Rating Scale for Depression (HAM-D), and the Symptom Checklist-90, revised (SCL-90-R). All subjects had platelets assayed for [³H] paroxetine binding. There were no significant differences between probands and sisters, but both groups scored significantly lower than a previously studied control group on B(max). There were no differences on Kd. Neither B(max) nor K(d) was related to most trait or symptomatic measures. Paroxetine binding could reflect endophenotypes common to BPD probands and their first-degree relatives.

OBJECTIVE: To investigate the effects of acute alcohol intoxication on eating-related urges among women with bulimia nervosa (BN). METHOD: Participants included women with BN or normal-weight eating disorder NOS with regular binge/purge symptoms (N = 13), and normal-eater control women (N = 17). Tested individually, the women reported on their mood state as well as on urges to binge eat and engage in various compensatory behaviors, prior to consuming alcohol, and again at 60 and 180 min following the consumption of 1.0 ml kg(-1) alcohol. RESULTS: Both groups reported feeling less clearheaded after drinking, as well as initial subjective mood stimulation followed by subsequent mood lowering. In addition, BN participants reported reductions in their urges to binge eat, exercise compulsively, and restrict food intake following alcohol consumption-the urge to purge was not significantly affected. DISCUSSION: Among women with BN, alcohol consumption appeared to reduce select eating-related urges with concomitant reductions in attention or concentration.

RESUMO

BACKGROUND & AIM: We studied FibroTouch (FT) and Fibroscan (FS) examination results and their repeatability when performed by healthcare personnel of different background. METHODS: FT and FS examinations were performed on patients with chronic liver disease by two operators, a doctor and a nurse, twice on each patient, at two different time points, independent of each other. RESULTS: The data for 163 patients with 1304 examinations was analyzed. There was strong correlation between FT and FS for attenuation parameter (Spearman's rho 0.76, p<0.001) and liver stiffness measurement (LSM) (Spearman's rho 0.70, p<0.001). However, FT produced higher value at lower attenuation parameter and LSM, and lower value at higher attenuation parameter and LSM. There was substantial agreement when using 15kPa LSM cut-off, but only moderate agreement when using 10kPa and 20kPa LSM cut-offs and 248dB/m, 268dB/m and 280dB/m attenuation parameter cut-offs. The IQR for attenuation parameter and IQR/median for LSM were significantly lower for FT compared with FS (4dB/m vs 27dB/m, p<0.001, and 10 vs 12, p<0.001, respectively). The intra- and inter-observer reliability of attenuation parameter and LSM using FT and FS were good to excellent with intraclass correlation coefficients 0.89-0.99. FT had shorter examination time (33s vs 47s, p<0.001) and less invalid measurements (0 vs 2, p<0.001). CONCLUSION: Measurements obtained with FT and FS strongly correlated, but significant differences in their absolute values, consistency, examination time and number of invalid measurements were observed. Either device can be used by healthcare personnel of different backgrounds when sufficiently trained.

RESUMO

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The world is currently challenged to handle this pandemic. The common symptoms of COVID-19 are fever, cough, fatigue, and shortness of breath. There are few reports on the association of SARS-CoV-2 with ocular abnormalities including conjunctivitis. We report a case of a 54-year-old woman who presented solely with conjunctivitis subsequently diagnosed with COVID-19. A lack of full history of her travel abroad was another issue leading to a delay in evaluating her COVID-19 status that increased the infection risk to her managing team. Thus, primary care practitioners should be suspicious of this atypical feature of COVID-19, thus enabling us to identify such patients at entry points. Maintaining safety measures while managing patients is also crucial.
