RESUMO

INTRODUCTION: Delayed cataract surgery has long been known to cause lens-induced glaucoma (LIG). This study examined the demographic and clinical profile, ocular characteristics and outcomes of LIG in a tertiary referral centre in Malaysia. MATERIALS AND METHODS: Data from the National Eye Database (Malaysia) for cataract surgery performed at Hospital Taiping, Perak, between January 2019 and December 2020 were reviewed. The medical records of patients with LIG were retrieved to obtain demographic data, clinical profiles and visual outcomes. RESULTS: Of 3233 patients who underwent cataract surgery at Hospital Taiping, Perak, between 2019 and 2020, 25 underwent emergency surgery for LIG. However, only 24 patients fulfilling the diagnostic criteria for LIG were included in the study: 14 (58.33%) patients with phacomorphic and 10 (41.6%) patients with phacolytic glaucoma. The mean age of the patients was 66±12 years. Women and men were equally affected. Most patients were Malay (75%), followed by Chinese (16.67%) and Indian (8.33%). The anterior chamber depth (ACD) was significantly shallow with a mean value of 2.72 mm. Nineteen (79.1%) patients presented with visual acuity of worse than counting fingers. The mean intraocular pressure (IOP) at presentation was 47.5±13.66mmHg, which improved to 15.08±8.09mmHg postoperatively. A best-corrected visual acuity of 6/15 and better was achieved in 20 patients (83.33%) despite glaucomatous optic neuropathy being present in 41.67% of the cases. The majority (58.3%) of surgeries were performed via extracapsular cataract extraction, while six (25%) of our patients underwent successful phacoemulsification. Seven (29.17%) patients had intraocular complications: five with zonular dialysis and two with posterior capsule rupture. Of these seven cases, four ended up with intracapsular cataract extraction, leaving two of them aphakic. CONCLUSION: Prompt cataract surgery is paramount in all LIG cases to reduce IOP and achieve better visual outcomes. Despite the promising prognosis associated with early surgical intervention, patients should be counselled about the potential for a guarded visual prognosis from complicated surgery and its long-term complications.

RESUMO

BACKGROUND: The use of Mohs micrographic surgery (MMS) in melanoma treatment has divided opinion and evidence-based guidelines are lacking. OBJECTIVES: This systematic review aimed to analyse clinical outcomes for patients with invasive melanomas treated with Mohs rather than wide local excision (WLE). METHODS: Embase, MEDLINE and Cochrane databases (to 30 August 2023) were searched for studies using Mohs to treat invasive melanoma. Outcomes of interest were local recurrence and death from melanoma. RESULTS: Thirty-five articles involving 41,499 patients with invasive melanoma treated with Mohs were identified. Sixteen studies compared Mohs with WLE and 19 were Mohs-only, non-comparative studies. Patients treated with Mohs differed significantly from those undergoing WLE, in particular Mohs patients were older and had thinner melanomas. Two comparative studies using the same data source reported adjusted hazard ratios for melanoma-specific death and both showed no significant difference between Mohs and WLE-treated patients; 0.87 (95% CI 0.55-1.35) and 1.20 (95% CI 0.71-20.36). There was also no statistically significant difference in local recurrence risk; the unadjusted risk ratio for patients treated with Mohs was 0.46 (95% CI 0.14-1.51 p = 0.20) with moderate heterogeneity (I2 = 62%). No studies reported multivariable analyses for risk of local recurrence. Many studies generated from relatively few and often overlapping data sets have reported the use of Mohs to treat patients with invasive melanoma. Fewer studies were comparative between Mohs and WLE and these reported substantially different baseline risks of recurrence and death from melanoma between the groups. Mohs has generally been used for thinner melanomas in older patients; therefore, comparisons based on univariable analyses are likely to have been misleading. CONCLUSIONS: On the basis of currently available data, it is not possible to reliably assess whether outcomes differ if invasive melanomas with comparable features are treated with Mohs or WLE, and randomized trial evidence will be required for reliable conclusions to be reached.

RESUMO

INTRODUCTION: Thalassaemia is one of the major health problems in Malaysia. With safe blood transfusion regime, the lifespan of patients with transfusion-dependent thalassaemia (TDT) has improved but at the cost of a higher risk of developing endocrine disorders. It is crucial for us to monitor the iron overload to prevent end organ damage. This study aims to evaluate the iron burden and prevalence of endocrinopathies in patients with TDT in Sarawak. MATERIALS AND METHODS: This retrospective cohort study was conducted between January 2020 to June 2020 in six government hospitals in Sarawak. A total of 89 patients with TDT, aged 10 years and above, were recruited. RESULTS: Out of the 89 patients, there were 54 males (60.7%) and 35 females (39.3%) with a median age of 21 years (range 10.0-65.0). Sixty-seven (75.3%) patients had betathalassaemia major and 15 (16.9%) patients had haemoglobin E beta-thalassaemia (HbE beta-thalassaemia), remaining seven patients had other genotypes. Thirty-one (34.8%) patients had mean serum ferritin 2500ng/ml and above, and 44 (66.6%) had liver iron concentration (LIC) ≥7mg/g. The prevalence of endocrine disorders in our cohort was 69.7%. The most common endocrinopathies were short stature (n=46, 51.7%), followed by hypogonadism (n=24, 26.9%), delayed puberty (n=23, 25.8%), hypothyroidism (n=10, 11.2%), diabetes mellitus (n=9, 10.1%), impaired glucose tolerance (n=6, 6.7%) and hypoparathyroidism (n=3, 3.3%). Endocrinopathies were significantly associated with age (p=0.01), age at initiating regular blood transfusion (p<0.01) and duration of regular blood transfusion (p<0.01). CONCLUSION: Our data shows that the development of endocrinopathies in TDT can be time dependent. Early detection of endocrine-related complications and prompt treatment with iron chelation therapy are important to improve morbidity and mortality. A multidisciplinary approach with good patient-doctor collaboration is the key to improving patient care in our settings.

RESUMO

BACKGROUND: Neoadjuvant dabrafenib plus trametinib has a high pathological response rate and impressive short-term survival in patients with resectable stage III melanoma. We report 5-year outcomes from the phase II NeoCombi trial. PATIENTS AND METHODS: NeoCombi (NCT01972347) was a single-arm, open-label, single-centre, phase II trial. Eligible patients were adults (aged ≥18 years) with histologically confirmed, resectable, RECIST-measurable, American Joint Committee on Cancer seventh edition clinical stage IIIB-C BRAF V600E/K-mutant melanoma and Eastern Cooperative Oncology Group performance status ≤1. Patients received 52 weeks of treatment with dabrafenib 150 mg (orally twice per day) plus trametinib 2 mg (orally once per day), with complete resection of the pre-therapy tumour bed at week 12. RESULTS: Between 20 August 2014 and 19 April 2017, 35 patients were enrolled. At data cut-off (17 August 2021), the median follow-up was 60 months [95% confidence interval (CI) 56-72 months]. Overall, 21 of 35 (60%) patients recurred, including 12 (57%) with first recurrence in locoregional sites (followed by later distant recurrence in 6) and 9 (43%) with first recurrence in distant sites, including 3 in the brain. Most recurrences occurred within 2 years, with no recurrences beyond 3 years. At 5 years, recurrence-free survival (RFS) was 40% (95% CI 27% to 60%), distant metastasis-free survival (DMFS) was 57% (95% CI 42% to 76%), and overall survival was 80% (95% CI 67% to 94%). Five-year survival outcomes were stratified by pathological response: RFS was 53% with pathological complete response (pCR) versus 28% with non-pCR (P = 0.087), DMFS was 59% versus 55% (P = 0.647), and overall survival was 88% versus 71% (P = 0.205), respectively. CONCLUSIONS: Neoadjuvant dabrafenib plus trametinib has high pathological response rates in clinical stage III melanoma, but low rates of RFS, similar to those achieved with adjuvant targeted therapy alone. Patients with a pCR to dabrafenib plus trametinib still had a high risk of recurrence, unlike that seen with immunotherapy where recurrences are rare.

RESUMO

BACKGROUND: Type 2 diabetes in young people is an aggressive disease with a greater risk of complications leading to increased morbidity and mortality during the most productive years of life. Prevalence in the UK and globally is rising yet experience in managing this condition is limited. There are no consensus guidelines in the UK for the assessment and management of paediatric type 2 diabetes. METHODS: Multidisciplinary professionals from The Association of Children's Diabetes Clinicians (ACDC) and the National Type 2 Diabetes Working Group reviewed the evidence base and made recommendations using the Grading Of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. RESULTS AND DISCUSSION: Young people with type 2 diabetes should be managed within a paediatric diabetes team with close working with adult diabetes specialists, primary care and other paediatric specialties. Diagnosis of diabetes type can be challenging with many overlapping features. Diabetes antibodies may be needed to aid diagnosis. Co-morbidities and complications are frequently present at diagnosis and should be managed holistically. Lifestyle change and metformin are the mainstay of early treatment, with some needing additional basal insulin. GLP1 agonists should be used as second-line agents once early ketosis and symptoms are controlled. Glycaemic control improves microvascular but not cardiovascular risk. Reduction in excess adiposity, smoking prevention, increased physical activity and reduction of hypertension and dyslipidaemia are essential to reduce major adverse cardiovascular events. CONCLUSIONS: This evidence-based guideline aims to provide a practical approach in managing this condition in the UK.

RESUMO

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic created many challenges for Hong Kong residents attempting to maintain healthy lifestyle habits. This study aimed to measure the prevalences of unhealthy dietary habits and physical inactivity levels in Hong Kong Chinese, identify associated factors, and conduct a time trend analysis during the third wave of the COVID-19 pandemic. METHODS: A cross-sectional telephone survey was conducted in Hong Kong by simple random sampling. The survey comprised socio-demographic characteristics, clinical information, the Hong Kong Diet Score (HKDS), smoking and alcohol consumption, and a Chinese version of the International Physical Activity Questionnaire Short Form. The composite outcome was low HKDS, physical inactivity, smoking, and alcohol consumption. We used 14 Health Behaviour Survey reports from 2003 to 2019 to establish a trend analysis regarding fruit and vegetable consumption, physical activity level, smoking, and alcohol consumption. RESULTS: We performed 1500 complete telephone surveys with a response rate of 58.8%. Most participants were older adults (≥65 years, 66.7%), women (65.6%), and married (77.9%). The HKDS was significantly lower in men, single individuals, low-income participants, alcohol drinkers, and patients with diabetes mellitus or renal disease. Participants who were single, undergoing long-term management of medical diseases, or had diabetes or renal diseases exhibited greater likelihood of physical inactivity. CONCLUSION: Prevalences of unhealthy lifestyle habits were high among men, single individuals, and chronic disease patients during the third wave of the COVID-19 pandemic in Hong Kong. The adoption of physical activity habits tended to decrease in the past two decades.

RESUMO

INTRODUCTION: The aim of this study was to analyse the clinical characteristics of patients with rheumatoid arthritis receiving biologics therapy and investigate the association between types of biologics and tuberculosis (TB) infections in 13 tertiary hospitals in Malaysia. MATERIALS AND METHODS: This was a retrospective study that included all RA patients receiving biologics therapy in 13 tertiary hospitals in Malaysia from January 2008 to December 2018. RESULTS: We had 735 RA patients who received biologics therapy. Twenty-one of the 735 patients were diagnosed with TB infection after treatment with biologics. The calculated prevalence of TB infection in RA patients treated with biologics was 2.9% (29 per 1000 patients). Four groups of biologics were used in our patient cohort: monoclonal TNF inhibitors, etanercept, tocilizumab, and rituximab, with monoclonal TNF inhibitors being the most commonly used biologic. The median duration of biologics therapy before the diagnosis of TB was 8 months. 75% of patients had at least one co-morbidity and all patients had at least one ongoing cDMARD therapy at the time of TB diagnosis. More than half of the patients were on steroid therapy with an average prednisolone dose of 5 mg daily. CONCLUSION: Although the study population and data were limited, this study illustrates the spectrum of TB infections in RA patients receiving biologics and potential risk factors associated with biologics therapy in Malaysia.

RESUMO

INTRODUCTION: The free helical rim (FHR) flap offers like-with-like reconstruction for full-thickness nasal defects. A case series of nasal reconstruction using an FHR flap was presented, detailing surgical steps and refinements, as well as functional and esthetic outcomes. METHODS AND MATERIALS: This is a retrospective cohort study of composite nasal defect reconstruction with FHR flap from August 2018 to March 2020. Descriptive data were analyzed by SPSS software. RESULTS: Six cases were recruited, four were unilateral alar defects, one was hemi-nose, and one was ala plus tip. The average size of the defect was 2.5 × 2.8 cm2. Three FHR flaps were designed with retrograde pedicles and three with anterograde pedicles. The facial artery and veins were the recipient vessels in all cases. Vascular grafts were used in all six cases. Descending branch of the lateral circumflex femoral (DLCxF) artery and vein functioned as interposition vascular conduits in five cases. Superficial forearm vein grafts were used in one case. One patient needed flap re-exploration due to venous congestion. One patient had partial flap necrosis due to delayed infection, and one developed delayed wound dehiscence in the irradiated wound. The average follow-up was 18 months. CONCLUSION: The FHR flap has consistent vascular anatomy. It can be raised as an anterograde or retrograde flap for a contralateral or ipsilateral inset. FHR flap can be used in extensive composite nasal defects. This case series demonstrates that interposition vascular grafts are invariably needed and the possibility of using forearm vessels as grafts instead of DLCxF artery and vein.

RESUMO

OBJECTIVES: Multicomponent exercise program have shown to improve function and cognition in older adults but studies on pre-frail older adults in the primary care setting are limited. This study aimed i) to evaluate impact of 6 months exercise (Ex) versus complementary effect of 3 months of cognitive stimulation therapy (CST) to 6 months of Ex (Ex+CST) on physical function, muscle mass and cognition versus control group at 3, 6 and 12 months ii) inflammatory biomarkers such as Interleukin-6 (IL-6) and Tumor Necrosis Factor Alpha (TNF-α). DESIGN: Cluster randomised control trial. SETTING AND INTERVENTION: Pre-frail older adults ≥ 65 years attending primary care clinic. Two intervention groups i) Ex 6 months ii) CST 3 months with Ex 6 months. MEASUREMENTS: At 0, 3, 6 and 12 months, questionnaires (on demographics, physical function, cognition, and depression) were administered and physical function assessment (gait speed, short physical performance battery (SPPB) test, handgrip strength, five times sit-to-stand (5x-STS)) was conducted. Muscle mass and its surrogates such as phase angle and body cell mass were measured using bioelectrical impedance analysis machine. Inflammatory biomarkers were measured at 0 and 3 months. RESULTS: Data from 190 participants was analysed at 3 months (111 control, 37 Ex and 41 Ex+CST). At 3 months, significant improvement in cognition was seen only in the Ex+CST group whereas improvements in depression, gait speed, SPPB and 5x-STS were seen in both the Ex and Ex+CST groups. At 6 months, the Ex+CST group improved in cognition and depression whereas improvement in frailty and muscle mass indices were seen in both the interventions groups. At 12 months, both the interventions groups had better perceived health, gait speed and less decline in muscle mass compared with control groups. Both the Ex and Ex+CST had significant association with TNF-α at 3 months (ß -2.71 (95% CI -4.80 - -0.62); p = 0.012 and ß -1.74 (95% CI -3.43 - -0.06); p = 0.043 respectively). CONCLUSION: Combined Ex+CST had significant improvement in cognition whereas the intervention groups improved in depression, physical function, muscle mass, frailty, perceived health and TNF-α levels. With growing evidence of the benefits of multicomponent interventions at primary care level, incorporating it into mainstream care with action plans on long-term sustainability and scalability should be a priority for every country.

RESUMO

BACKGROUND: A tax of one-Mexican peso per liter of sugar-sweetened beverage (SSB) came into effect in January 2014 in Mexico as a national health policy to tackle the high overweight and obesity prevalence. Previous studies have shown an overall reduction in SSB purchases after the tax implementation. However, it remains unknown whether and to what extent SSB consumers switched to cheaper taxed beverages, attenuating the potential effect of the policy. Our study's objective was to estimate changes in household purchases of taxed SSBs by tertiles of SSB prices (low, middle, and high) in urban areas after the SSB tax implementation in 2014. METHODS: Based on purchase data for 2012-2015 from households living in 54 Mexican cities with a population > 50,000 inhabitants, we calculated unit-value SSB prices for the full period and sorted them on a monthly basis to create monthly price tertiles. We merged these price tertiles to household purchases and created average monthly ml/capita/day SSB purchases by price tertile at the city level. We assessed SSB purchase switching patterns before and after the tax implementation through price-tertile stratified linear models. The main variable in the models was a dummy indicator that allowed us to identify the pre-tax period (2012-13) and post-tax period (2014-15). We controlled our models for time trends and contextual economic variables. RESULTS: In the regression adjusted models, we found a statistically significant purchase reduction ranging between 10.80 and 13.79 ml/capita/day (p-value < 0.001) across taxed beverages from the middle-price SSB after the tax implementation. We observed no statistically significant reductions in purchases of low-price SSBs and high-price SSBs. CONCLUSIONS: Our findings show purchase reductions in the middle-price SSBs, which represents ≈30% of the overall SSB purchases in urban Mexico. Future studies should be conducted to test if the redesign of the current the tax, by either doubling the tax amount or taxing sugar content, might reduce more effectively purchases across all SSBs.

RESUMO

Food additives have been linked to the pro-inflammatory microbial dysbiosis associated with Crohn's disease (CD) but the underlying ecological dynamics are unknown. Here, we examine how selection of food additives affects the growth of multiple strains of a key beneficial bacterium (Faecalibacterium prausnitzii), axenic clinical isolates of proinflammatory bacteria from CD patients (Proteus, Morganella, and Klebsiella spp.), and the consortia of mucosa-associated microbiota recovered from multiple Crohn's disease patients. Bacterial growth of the axenic isolates was evaluated using a habitat-simulating medium supplemented with either sodium sulfite, aluminum silicate, carrageenan, carboxymethylcellulose, polysorbate 80, saccharin, sucralose, or aspartame, intended to approximate concentrations found in food. The microbial consortia recovered from post-operative CD patient mucosal biopsy samples were challenged with either carboxymethylcellulose and/or polysorbate 80, and the bacterial communities compared to unchallenged consortia by 16S rRNA gene amplicon profiling. Growth of all F. prausnitzii strains was arrested when either sodium sulfite or polysorbate 80 was added to cultures at baseline or mid-exponential phase of growth, and the inhibitory effects on the Gram-negative bacteria by sodium sulfite were conditional on oxygen availability. The effects from polysorbate 80, saccharin, carrageenan, and/or carboxymethylcellulose on these bacteria were strain-specific. In addition to their direct effects on bacterial growth, polysorbate 80 and/or carboxymethylcellulose can drive profound changes in the CD mucosa-associated microbiota via niche expansion of Proteus and/or Veillonellaceae - both implicated in early Crohn's disease recurrence. These studies on the interaction of food additives with the enteric microbiota provide a basis for dietary management in Crohn's disease.

RESUMO

BACKGROUND: Neoadjuvant ipilimumab plus nivolumab has yielded high response rates in patients with macroscopic stage III melanoma. These response rates translated to high short-term survival rates. However, data on long-term survival and disease recurrence are lacking. PATIENTS AND METHODS: In OpACIN, 20 patients with macroscopic stage III melanoma were randomized to ipilimumab 3 mg/kg plus nivolumab 1 mg/kg q3w four cycles of adjuvant or split two cycles of neoadjuvant and two adjuvant. In OpACIN-neo, 86 patients with macroscopic stage III melanoma were randomized to arm A (2× ipilimumab 3 mg/kg plus nivolumab 1 mg/kg q3w; n = 30), arm B (2× ipilimumab 1 mg/kg plus nivolumab 3 mg/kg q3w; n = 30), or arm C (2× ipilimumab 3 mg/kg q3w plus 2× nivolumab 3 mg/kg q2w; n = 26) followed by surgery. RESULTS: The median recurrence-free survival (RFS) and overall survival (OS) were not reached in either trial. After a median follow-up of 69 months for OpACIN, 1/7 patients with a pathologic response to neoadjuvant therapy had disease recurrence. The estimated 5-year RFS and OS rates for the neoadjuvant arm were 70% and 90% versus 60% and 70% for the adjuvant arm. After a median follow-up of 47 months for OpACIN-neo, the estimated 3-year RFS and OS rates were 82% and 92%, respectively. The estimated 3-year RFS rate for OpACIN-neo was 95% for patients with a pathologic response versus 37% for patients without a pathologic response (P < 0.001). In multiple regression analyses, pathologic response was the strongest predictor of disease recurrence. Of the 12 patients with distant disease recurrence after neoadjuvant therapy, 5 responded to subsequent anti-PD-1 and 8 to targeted therapy, although 7 patients showed progression after the initial response. CONCLUSIONS: Updated data confirm the high survival rates after neoadjuvant combination checkpoint inhibition in macroscopic stage III melanoma, especially for patients with a pathologic response. Pathologic response is the strongest surrogate marker for long-term outcome.

RESUMO

Recent innovations within the field of robotic surgery have particular relevance to colorectal surgery. Although a robotic approach has been associated with satisfactory outcomes, there remains a wide variation in levels of adoption. In particular, this study focuses on patient positioning, docking, and table placement, with the intent of understanding the strength of opinion of colorectal surgeons in the Asia-Pacific region to the practical application of these developments to achieve optimal surgical outcomes. Using a modified Delphi methodology, a steering group of colorectal surgeons with experience in robotic surgery from across the Asia-Pacific region identified 35 consensus statements. An online 4-point Likert scale questionnaire was distributed to surgeons in the Asia-Pacific region using convenience sampling. Respondents were excluded from further analysis if they did not perform colorectal surgery or had no experience in robotic surgery. A total of 140 responses (71.8% response rate) were received between August and October 2021. 22 statements attained a very high degree of agreement (≥ 90%). High agreement (< 90% and ≥ 75%) was achieved in another 12, and one failed to meet the consensus threshold (< 75%). A set of five recommendations were developed based on these results. The high levels of agreement demonstrate recognition amongst colorectal surgeons within the Asia-Pacific region of the potential advantage of recent improvements in robotic surgery technology to further improve surgical outcomes. The recommendations may inform a set of practical principles to help standardise the use of colorectal robotic surgery, which may also be relevant to other surgical fields.

RESUMO

The radial forearm free flap (RFFF) is widely used for oral reconstruction. The superficial circumflex iliac artery perforator (SCIP) flap is an increasingly utilized alternative. The cases of 165 patients who received either an RFFF or SCIP flap for oral reconstruction at Chris O'Brien Lifehouse, Sydney were reviewed. The aim was to report on patient, pathology, treatment, and outcome variables and to compare these between the two flap groups. A RFFF was used in 126 patients and a SCIP flap in 39 patients. SCIP flap patients were younger (P < 0.001) and had shorter operative times (P < 0.001), shorter anaesthetic times (P < 0.001), and more frequent recipient site dehiscence (P = 0.005) when compared to RFFF patients. The SCIP flap was significantly less frequently used for composite resections including bone when compared to the RFFF (P < 0.001). The primary site distribution was more even for RFFF patients (P < 0.001). There were no SCIP flap failures; three RFFF failures occurred. SCIP flaps performed comparably in terms of operative and clinical outcomes. Most SCIP flaps were utilized in younger patients with partial glossectomy defects.

RESUMO

BACKGROUND: Neoadjuvant chemoradiotherapy is a standard treatment for locally advanced rectal cancer, for which pathological complete response is typically used as a surrogate survival endpoint. Neoadjuvant rectal score is a new biomarker that has been shown to correlate with survival. The main objectives of this study were to investigate factors contributing to pathological complete response, to validate the prognostic significance of neoadjuvant rectal score, and to investigate factors associated with a lower neoadjuvant rectal score in a cohort of Hong Kong Chinese. METHODS: Data of patients with locally advanced rectal cancer who received neoadjuvant chemoradiotherapy from August 2006 to October 2018 were retrieved from hospital records and retrospectively analysed. RESULTS: Of 193 patients who had optimal response to neoadjuvant chemoradiotherapy and surgery, tumour down-staging was the only independent prognostic factor that predicted pathological complete response (P<0.0001). Neoadjuvant rectal score was associated with overall survival (hazard ratio [HR]=1.042, 95% confidence interval [CI]=1.021-1.064; P<0.0001), disease-free survival (HR=1.042, 95% CI=1.022-1.062; P<0.0001), locoregional recurrence-free survival (HR=1.070, 95% CI=1.039-1.102; P<0.0001) and distant recurrence-free survival (HR=1.034, 95% CI=1.012-1.056; P=0.002). Patients who had pathological complete response were associated with a lower neoadjuvant rectal score (P<0.0001), but pathological complete response was not associated with survival. For patients with intermediate neoadjuvant rectal scores, late recurrences beyond 72 months from diagnosis were observed. CONCLUSION: Neoadjuvant rectal score is an independent prognostic marker of survival and disease recurrence in a cohort of Hong Kong Chinese patients who received neoadjuvant chemoradiotherapy for locally advanced rectal cancer.

RESUMO

OBJECTIVES: To assess the prevalence of caregiver anxiety and to identify correlates of caregiver anxiety in family caregivers of patients with advanced cancer in a palliative care unit in Hong Kong. METHODS: Family caregivers of patients admitted to the palliative care ward for the first time between July 2019 and September 2019 were screened for recruitment. Caregiver demographics (age, sex, marital status, occupation, education level, housing condition, relationship with the patient, known diagnosis of anxiety or depression, and Charlson comorbidity index) were collected, as were caregiver understanding of patient's diagnosis and prognosis, perceived patient's distress, frequency of witnessing confusion or delirium of patients in past month, perceived adequacy of psychological support (other than general social support), and perceived anxiety towards patient's approaching death. Caregiver anxiety was assessed using the 7-item Generalised Anxiety Disorder scale (GAD-7). Caregiver depression status was assessed using the 9-item Patient Health Questionnaire (PHQ-9). Caregiver psychological well-being was assessed using the 11-item Psychological Well-being Scale for Family Caregivers (PWS-C). Caregiver overall burden was assessed using the Chinese version of the 13-item Modified Caregiver Strain Index (C-M-CSI). RESULTS: 70 caregivers (of 66 patients) were included, with a response rate of 98.6%. 16 (22.9%) caregivers had moderate to severe anxiety (GAD-7 score of ≥10). The GAD-7 score was higher in female caregivers than in male caregivers (mean rank: 39.26 vs 27.83, p = 0.026). 26 (37.1%) caregivers had depression (PHQ-9 score of ≥7). The GAD-7 score of caregivers was associated with the PHQ-9 score (rs = 0.834, p < 0.01), the four subscales of PWS-C: social support (rs = -0.308, p = 0.01), life meaning (rs = -3.30, p < 0.01), emotional distress (rs = 0.615, p < 0.01), and caregiver inadequacy (rs = 0.41, p < 0.01), and the C-M-CSI score for caregiver overall burden (rs = 0.332, p < 0.01). In multiple linear regression, predictors for GAD-7 score were the PHQ-9 score, caregiver's feeling of anxiety towards patient's approaching death, and caregiver sex. CONCLUSIONS: 22.9% of family caregivers of patients with advanced cancer have moderate to severe anxiety. Anxiety of caregivers was associated with depression, caregiver's feeling of anxiety towards patient's approaching death, psychological support, and life meaning. All these are potentially amendable by interventions. A structured screening of anxiety in family caregivers of patients with advanced cancer should be considered as routine practice.

RESUMO

BACKGROUND: Enhancing patients' sense of dignity is the core element of high-quality palliative care. In Western countries, dignity therapy has shown promising positive effects on the sense of dignity and end-of-life experience. To apply this therapy in Chinese patients, a theory-driven, culturally relevant family-oriented dignity therapy was developed, guided by the Medical Research Council framework for complex intervention development. OBJECTIVES: This study examined the effectiveness of family-oriented dignity therapy in improving dignity-related distress, depression, and spiritual well-being in Chinese patients with lung cancer undergoing chemotherapy. DESIGN: A randomised controlled trial. SETTINGS AND METHODS: Patients who were diagnosed with lung cancer and undergoing chemotherapy were recruited using convenience sampling from a cancer hospital in Changsha, China. A significant family caregiver of each patient was invited to participate. Patients who met the inclusion criteria and agreed to participate (N = 120) were randomly assigned to receive family-oriented dignity therapy (intervention group, n = 60) or attention (control group, n = 60). The Patient Dignity Inventory, Patient Health Questionnaire-9, and Functional Assessment of Chronic Illness Therapy - Spiritual Well-being Scale were used to assess dignity-related distress, depression, and spiritual well-being, respectively, at baseline and 1- and 4-week follow-up. A generalised estimating equation was used to analyse the intervention effects across the time points. RESULTS: Compared with the control group, the patients in the intervention group showed significantly greater reduction in existential distress (ß: -1.372, 95% CI: -2.269, -0.472; p = 0.003) and depression (ß: -3.430, 95% CI: -5.032, -1.829; p < 0.001) at week one, as well as significantly greater improvement in spiritual well-being at both week one (ß: 3.705, 95% CI: 0.599, 6.811; p = 0.019) and week four (ß: 4.939, 95% CI: 0.476, 9.401; p = 0.030). CONCLUSIONS: Family-oriented dignity therapy has the potential to relieve existential distress and depressive symptoms and improve spiritual well-being. We expect our finding to impact research on family-oriented dignity therapy and enhance its effectiveness. We may also have an impact on nursing practice by providing a means to initiate conversations between nurses and the patients and family caregivers to relieve the psychosocial distress of patients during treatment. This study has been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR1900020806).

RESUMO

AIMS: The associations between prognostic awareness, acceptance of illness and psychological outcomes (anxiety, depression and spiritual well-being) remain unclear. This study examined the associations between prognostic awareness and various psychological outcomes and how they can be moderated by patient acceptance of illness (cancer). MATERIALS AND METHODS: In total, 1184 patients with stage IV solid cancer were recruited at major public hospitals across four Asian countries (China, India, Sri Lanka, Vietnam). Prognostic awareness and acceptance of illness were assessed through self-reported understanding of treatment intent and acceptance of illness, respectively. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale, whereas spiritual well-being was measured using the Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being Scale. Multivariate regressions were used to estimate the associations while controlling for patient characteristics. RESULTS: Compared with being unaware of their prognosis (i.e. believing that their cancer is curable), being aware or unsure of their prognosis was associated with higher anxiety and depressive symptoms, and lower spiritual well-being scores. Acceptance of illness moderated these relationships and improved the psychological outcomes. CONCLUSIONS: The results suggest that disclosure of prognostic information should be provided in conjunction with psychological interventions that focus on acceptance of illness.
