RESUMO

AIMS: The rate of size change in brain metastasis may have clinical implications on tumour biology and prognosis for patients who receive stereotactic radiotherapy (SRT). We analysed the prognostic value of brain metastasis size kinetics and propose a model for patients with brain metastases treated with linac-based SRT in predicting overall survival. MATERIALS AND METHODS: We analysed the patients receiving linac-based SRT between 2010 and 2020. Patient and oncological factors, including the changes in sizes of brain metastasis between the diagnostic and stereotactic magnetic resonance imaging, were collected. The associations between prognostic factors and overall survival were assessed using Cox regression with least absolute selection and shrinkage operator (LASSO) checked by 500 bootstrap replications. Our prognostic score was calculated by evaluating the most statistically significant factors. Patients were grouped and compared according to our proposed score, Score Index for Radiosurgery in Brain Metastases (SIR) and Basic Score for Brain Metastases (BS-BM). RESULTS: In total, 85 patients were included. We developed the prognostic model based on the most important predictors of overall survival: growth kinetics, i.e. percentage change in brain metastasis size per day between the diagnostic and stereotactic magnetic resonance imaging (hazard ratio per 1% increase, 1.32; 95% confidence interval 1.06-1.65), extracranial oligometastatic diseases (≤5 involvements) (hazard ratio 0.28; 95% confidence interval 0.16-0.52) and the presence of neurological symptoms (hazard ratio 2.99; 95% confidence interval 1.54-5.81). Patients with scores 0, 1, 2 and 3 had a median overall survival of 44.4 (95% confidence interval 9.6-not reached), 20.4 (95% confidence interval 15.6-40.8), 12.0 (95% confidence interval 7.2-22.8) and 2.4 (95% confidence interval 1.2-not reached) years, respectively. The optimism-corrected c-indices for our proposed model, SIR and BS-BM were 0.65, 0.58 and 0.54, respectively. CONCLUSIONS: Brain metastasis growth kinetics is a valuable metric for survival outcomes of SRT. Our model is useful in identifying patients with brain metastasis treated with SRT with different overall survival.

RESUMO

Cyanobacteria are ubiquitous in aquatic and terrestrial environments worldwide and include a number of species producing tumor-promoting hepatotoxins. Human exposure to cyanobacteria and cyanotoxins primarily occurs though ingestion of contaminated drinking water and food sources. In a Northeast U.S. population, we recently reported an independent association of oral cyanobacteria with risk of hepatocellular carcinoma (HCC). In a cross-sectional study of 55 HCC patients in Hawaii, U.S.A., serum microcystin/nodularin (MC/NOD), cylindrospermopsin (CYN), and anabaenopeptin (AB) were measured by ELISA. In a subset of 16 patients, cyanotoxin levels were compared by tumor expression of over 700 genes analyzed via the Nanostring nCounter Fibrosis panel. MC/NOD, CYN, and AB were detected in all HCC patients. MC/NOD and CYN levels significantly varied by etiology with the highest levels in cases attributed to metabolic risk factors, specifically, hyperlipidemia, type 2 diabetes, and non-alcoholic fatty liver disease/non-alcoholic steatohepatitis. Cyanotoxin levels were significantly positively correlated with tumor expression of genes functioning in PPAR signaling and lipid metabolism. Our study provides novel albeit limited evidence that cyanotoxins may a role in the pathogenesis of HCC through the dysregulation of lipid metabolism and progression of hepatic steatosis.

RESUMO

The purpose of this research is to investigate the effectiveness of Digital Content Marketing (DCM) on a Mixed Reality (MR) training platform environment with the consideration of online purchase intention (OPI) through social media. E-commerce today encounters several common issues that cause customers to have reservations to purchase online. With the absence of physical contact points, customers often perceive more risks when making purchase decisions. Furthermore, online retailers often find it hard to engage customers and develop long-term relationships. In this research, a Structural Equation Model (SEM) is proposed to examine the efficacy of DCM from both immediate and long-term OPI. The results examine whether adopting DCM on an MR training platform environment through social media brings positive results in OPI. Empirical research was carried out through online questionnaires collected in 2021 and 2022. A total of 374 questionnaires were qualified for data analysis in this study, conducted with IBM SPSS and AMOS. The results imply that DCM is critical to stimulating both immediate and long-term OPI. The immediate OPI is positively affected by increasing perceived value through MR in DCM. Regarding the long-term OPI, increased customer engagement with DCM under MR environment can cultivate brand trust and significantly affect the long-term OPI.

RESUMO

AIMS: Multiple studies have shown conflicting results on the correlation between the EGFR T790M quantitative level and survival outcomes in osimertinib-treated patients. We sought to validate such correlations using data from an osimertinib early access programme (EAP) providing access for metastatic non-small cell lung cancer patients with limited treatment options. PATIENTS AND METHODS: This observational, multicentre, retrospective analysis included EAP participants who received osimertinib until disease progression, intolerable toxicities or death. Digital droplet polymerase chain reaction-based quantitative plasma genotyping was carried out upon disease progression and data were analysed to explore the relationships between T790M mutant allele fraction (MAF), T790M copy number, MAF ratio and post-osimertinib overall survival. Real-world treatment outcomes and safety were also evaluated. RESULTS: Data from 156 EAP participants were analysed (median follow-up 37.7 months). The median age was 62 years, 62.2% were women, 79.5% were never-smokers, 60.9% had Eastern Cooperative Oncology Group performance status 0/1. In patients with available plasma data (n = 114), T790M MAF (%) showed no significant relationships with overall survival (hazard ratio 1.02; 95% confidence interval 0.99-1.04) or time to treatment discontinuation (TTD) (hazard ratio 1.01; 95% confidence interval 0.98-1.04). Absolute T790M copy number and T790M to activating EGFR mutation MAF ratio also showed no prognostic value. The investigator-assessed response rate was 42.3% and the disease control rate was 85.5%. The median TTD was 15.8 (95% confidence interval 12.5-18.5) months and the median overall survival was 22.3 (95% confidence interval 18.6-26.1) months. CONCLUSION: T790M MAF did not correlate with TTD or overall survival in this EAP cohort but limitations should not be overlooked. Observed survival outcomes and the toxicity profile were consistent with data from other real-world series.

RESUMO

INTRODUCTION: To determine the carrier frequency and common mutations of Mendelian variants in Chinese couples using next-generation sequencing (NGS). METHODS: Preconception expanded carrier testing using NGS was offered to women who attended the subfertility clinic. The test was then offered to the partners of women who had positive screening results. Carrier frequency was calculated, and the results of the NGS panel were compared with those of a target panel. RESULTS: One hundred twenty-three women and 20 of their partners were screened. Overall, 84 (58.7%) individuals were identified to be carriers of at least one disease, and 68 (47.6%) were carriers after excluding thalassaemias. The most common diseases found were GJB2-related DFNB1 nonsyndromic hearing loss and deafness (1 in 4), alpha-thalassaemia (1 in 7), beta-thalassaemia (1 in 14), 21-hydroxylase deficient congenital adrenal hyperplasia (1 in 13), Pendred's syndrome (1 in 36), Krabbe's disease (1 in 48), and spinal muscular atrophy (1 in 48). Of the 43 identified variants, 29 (67.4%) were not included in the American College of Medical Genetics and Genomics or American College of Obstetrics and Gynecology guidelines. Excluding three couples with alpha-thalassaemia, six at-risk couples were identified. CONCLUSION: The carrier frequency of the investigated members of the Chinese population was 58.7% overall and 47.6% after excluding thalassaemias. This frequency is higher than previously reported. Expanded carrier screening using NGS should be provided to Chinese people to improve the detection rate of carrier status and allow optimal pregnancy planning.

RESUMO

OBJECTIVES: Tumor programmed death ligand 1 (PD-L1) expression is associated with improved clinical benefit from immunotherapies targeting the PD-1 pathway. We conducted a global, multicenter, retrospective observational study to determine real-world prevalence of tumor PD-L1 expression in patients with NSCLC. MATERIALS AND METHODS: Patients ≥18 years with histologically confirmed stage IIIB/IV NSCLC and a tumor tissue block (≤5 years old) obtained before treatment were identified in 45 centers across 18 countries. Tumor samples from eligible patients were selected consecutively, when possible. PD-L1 expression was evaluated at each center using the PD-L1 IHC 22C3 pharmDx kit (Agilent, Santa Clara, CA, USA). RESULTS: Of 2617 patients who met inclusion criteria, 2368 (90%) had PD-L1 data; 530 (22%) patients had PD-L1 TPS ≥ 50%, 1232 (52%) had PD-L1 TPS ≥ 1%, and 1136 (48%) had PD-L1 TPS < 1%. The most common reason for not having PD-L1 data (n = 249) was insufficient tumor cells (<100) on the slide (n = 170 [6%]). Percentages of patients with PD-L1 TPS ≥ 50% and TPS ≥ 1%, respectively were: 22%/52% in Europe; 22%/53% in Asia Pacific; 21%/47% in the Americas, and 24%/55% in other countries. Prevalence of EGFR mutations (19%) and ALK alterations (3%) was consistent with prior reports from metastatic NSCLC studies. Among 1064 patients negative for both EGFR mutation and ALK alteration, the percentage with PD-L1 TPS ≥ 50% and TPS ≥ 1%, respectively, were 27% and 53%. CONCLUSIONS: This is the largest real-world study in advanced NSCLC to date evaluating PD-L1 tumor expression using the 22C3 pharmDx kit. Testing failure rate was low with local evaluation of PD-L1 TPS across a large number of centers. Prevalence of PD-L1 TPS ≥ 50% and TPS ≥ 1% among patients with stage IIIB/IV NSCLC was similar across geographic regions and broadly consistent with central testing results from clinical trial screening populations.

RESUMO

BACKGROUND: Currently, there are no guidelines for management of moderate to severe mitral regurgitation (MR) in patients undergoing left ventricular assist device (LVAD) implantation. The present study aimed to investigate the impact of baseline MR on short and midterm survival in patients who had LVAD as destination therapy (DT). METHODS: The DT-LVAD patients were classified into 2 groups based on baseline MR status: ≥ moderate MR and < moderate MR. Baseline clinical characteristics and post-LVAD implant adverse events were compared. Unadjusted mortality rates at 30 days, 1 year, and 2 years were analyzed. RESULTS: Of 91 patients studied, 62 (68%) had ≥ moderate MR before LVAD implantation; ≥ moderate MR patients had a higher incidence of concomitant pulmonary disease (11% vs 0%; P = .001) and ≥ moderate tricuspid regurgitation (55% vs 23%, P = .004) than < moderate MR patients. Other baseline clinical characteristics were similar in both groups. Post-LVAD adverse events did not differ between the 2 groups. Survival rates at 30 days, 1 year, and 2 years for both groups (≥ moderate MR vs < moderate MR) were 90% vs 100% (P = .03), 63% vs 90% (P = .001), and 52% vs 83% (P = .002), respectively. On multivariable analysis, age, female sex, ≥ moderate tricuspid regurgitation, and ≥ moderate MR at baseline were found to be independent predictors of overall all-cause mortality. Overall survival was significantly lower in the ≥ moderate MR group than the < moderate MR group (log-rank test, P = .03). CONCLUSION: In DT LVAD patients, ≥ moderate MR is common and is associated with worse survival at both short and midterm follow-up.

RESUMO

OBJECTIVES: This study aimed to determine the prevalence of mental illness in offenders referred to psychiatrists from January 2011 to March 2016 and any associations between crime and mental illness in these offenders. METHODS: Case notes of offenders referred to psychiatrists at the Siu Lam Psychiatric Centre from 1 January 2011 to 31 March 2016 were reviewed. Data on sex, age on admission, educational level, principal psychiatric diagnosis, index offence, source and reason of referral, and outcome were collected. RESULTS: Case notes were reviewed for 4492 offenders (75% males) aged 14 to 93 (mean, 40.6) years. Of these, 68% were referred by the courts for psychiatric report and 32% were referred by correctional institutions for psychiatric assessment and treatment. Approximately 73% of them had a diagnosable mental disorder. The most common principal psychiatric diagnoses were schizophrenia and related disorders (25%), mental and behavioural disorders due to psychoactive substance use (20%), and mood disorders (9%). The most common index offences were theft and related offences (22%), acts intended to cause injury (20%), and illicit drug offences (11%). Offences involving violence were more prevalent in males than in females (p < 0.001). In terms of the three most common principal psychiatric diagnoses, 'acts intended to cause injury' was most prevalent in those with 'schizophrenia and other related disorders' than in those with the other two diagnoses (31% vs 19% vs 17%, p < 0.001). 'Theft and related offences' was most prevalent in those with mood disorders than in those with other two diagnoses (38% vs 20% vs 18%, p < 0.001). 'Illicit drug offences' was most prevalent in those with 'mental and behavioural disorders due to psychoactive substance' than those with other two diagnoses (22% vs 8% vs 6%, p < 0.001). CONCLUSIONS: The prevalence of mental disorders among offenders referred to psychiatrists is high. The pattern of associations between crime and mental disorders in these offenders is comparable with that reported in overseas studies. As Siu Lam Psychiatric Centre is the only facility in Hong Kong for mentally ill offenders, our sample is representative, and our results provide cross-sectional pattern of forensic psychiatric service utilisation in Hong Kong.

RESUMO

OBJECTIVES: This study aimed to validate the Correctional Mental Health Screen (CMHS) in the Hong Kong prison population and determine the prevalence of psychiatric disorders among remand prisoners in Hong Kong and the associated factors of mental illness. METHODS: This cohort study was conducted at the Lai Chi Kok Reception Centre and the Tai Lam Centre for Women in Hong Kong. Remand prisoners aged ≥21 years were recruited between May and August 2014. Sociodemographic and clinical data were collected. Each remand prisoner was assessed using the appropriate CMHS for males or for females, then interviewed by a specialist psychiatrist using the Structured Clinical Interview for DSM-IV for current affective disorder and psychotic disorder for cross-validation. RESULTS: A total of 245 remand prisoners were recruited (150 males and 95 females; mean age, 25.8 years). Of them, 51% (55% males and 44% females) had a lifetime history of psychiatric disorder, whereas 39.6% (46% males and 29.5% females) had a current psychiatric disorder. The most common psychiatric disorder was substance use disorder (>36%), followed by mood disorder (>20%), psychotic disorder (5.3%), and lifetime neurotic disorder (3.7%). Living in a public housing estate (odds ratio [OR] = 1.99), a history of childhood conduct problem (OR = 2.40), and a forensic history (OR = 1.97) were associated with an increased risk of having a psychiatric disorder. The CMHS had good diagnostic efficiency after cross-validation with the Structured Clinical Interview for DSM-IV. CONCLUSION: Psychiatric disorders are prevalent in remand prisoners in Hong Kong. The CMHS is an effective tool to screen remand prisoners for timely treatment of prisoners with mental health needs.

RESUMO

Aims: Gastrocnemius tightness predisposes to musculoskeletal pathology and may require surgical treatment. However, it is not clear what proportion of patients with foot and ankle pathology have clinically significant gastrocnemius tightness. The aim of this study was to compare the prevalence and degree of gastrocnemius tightness in a control group of patients with a group of patients with foot and ankle pathology. Patients and Methods: This prospective, case-matched, observational study compared gastrocnemius tightness, as assessed by the lunge test, in a control group and a group with foot and ankle pathology. Gastrocnemius tightness was calculated as the difference in dorsiflexion of the ankle with the knee extended and flexed. Results: A total of 291 controls were paired with 97 patients with foot and ankle pathology (FAP). The mean gastrocnemius tightness was 6.0° (sd 3.5) in controls and 8.0° (sd 5.7) in the FAP group (p < 0.001). Subgroup analysis showed a mean gastrocnemius tightness of 10.3° (sd 6.0) in patients with forefoot pathology versus 6.9° (sd 5.3) in patients with other pathology (p = 0.008). A total of 12 patients (37.5%) with forefoot pathology had gastrocnemius tightness of > two standard deviations of the control group (> 13°). Conclusion: Gastrocnemius tightness of > 13° may be considered abnormal. Most patients with foot and ankle pathology do not have abnormal degrees of gastrocnemius tightness compared with controls, but it is present in over a third of patients with forefoot pathology.

RESUMO

AIMS: Almost all patients with epidermal growth factor receptor (EGFR) mutations will develop resistance to first-line EGFR tyrosine kinase inhibitors (TKIs). The management of oligoprogression on EGFR TKI is controversial. Irradiating progressing tumours may potentially eradicate the resistant clone and allow continuation of EGFR TKI, but the clinical data remain sparse. We aimed to assess the effect of radiotherapy on survival outcomes in patients with oligoprogression in a matched-cohort study. MATERIALS AND METHODS: This was a retrospective matched-cohort study comparing patients with EGFR mutation-positive stage IV non-small cell lung cancer receiving radiotherapy versus chemotherapy for progression. Patients in the radiotherapy group received radiotherapy (mainly stereotactic ablative radiotherapy) for oligoprogression, whereas the chemotherapy group received only systemic chemotherapy upon progression. Key prognostic factors including gender, age, performance status, time to first progression and mutation subtypes were matched. RESULTS: Twenty-five patients with oligoprogression (radiotherapy group) were identified, and a matched chemotherapy group with the same number of patients was generated. The median duration of follow-up was 24.3 and 34 months for the radiotherapy and chemotherapy groups, respectively. The median overall survival of the radiotherapy group was significantly longer than the chemotherapy group, 28.2 versus 14.7 months (P = 0.026). The median progression-free survival (PFS) was 7.0 and 4.1 months after radiotherapy and chemotherapy, respectively (P = 0.0017). The use of radiotherapy was an independent predictive factor of overall survival and PFS in multivariate analysis. Only one patient had ≥grade 3 toxicity after radiotherapy. The frequency of secondary T790M mutation and subsequent Osimertinib exposure were similar in both groups. CONCLUSION: Radiotherapy may effectively extend EGFR TKI therapy for patients with oligoprogression on TKI. Improved PFS and overall survival were observed, although potential biases should not be overlooked. Further randomised studies are warranted.

RESUMO

OBJECTIVES: There has been controversy regarding whether or not people affected by leprosy have more cognitive dysfunction than healthy individuals. The purpose of this study was to assess cognitive functions and activities of daily living (ADL) in people affected by leprosy relative to a control population living in rural areas. MATERIALS AND METHODS: We assessed cognitive functions and ADL using the Korean Mini-Mental State Examination (K-MMSE), Korean Dementia Screening Questionnaire (KDSQ), and Seoul-Instrumental ADL (S-IADL). Higher scores of K-MMSE and lower scores of both KDSQ and S-IADL are indicative of better functioning. We assessed 224 persons living in Sorokdo who were affected by leprosy and 448 age- and gender-matched control subjects living in Namwon of the Chonbuk province. RESULTS: After adjusting for age, gender, and educational status, the K-MMSE score was found to be significantly higher in people affected by leprosy than in control subjects (23.14 ± 4.89 vs. 22.25 ± 4.62, respectively, P = 0.022). Items related to memory in the KDSQ showed no differences between the groups, but people affected by leprosy had a better score in division for other cognitive functions than controls. On items related to ADL in the KDSQ and S-IADL, people affected by leprosy performed significantly worse compared with controls. CONCLUSIONS: Our results suggest that although people affected by leprosy have a lower capacity of ADL, they may have better cognitive functions than normal controls.

RESUMO

The aim of the present study is to examine prospectively the quality of social networks of Hong Kong Chinese adults. A randomized household survey was employed. A total of 1170 Hong Kong Chinese respondents were recruited to the study. Participants ranged in age from 18 to 79 years, 43% of respondents were male. Findings revealed a negative association between familial trust and social network size. Network trust, social identification, and structural networks were all found to be positively associated with social network size and perceived respect from social network. The importance of family and the prioritization of the needs of the family over individual needs has implications on social network size and formation for Hong Kong Chinese individuals. More research is needed to further examine the importance of familial relationships and the prioritization of family and the impact this has on social network development and maintenance among Hong Kong Chinese.

RESUMO

OBJECTIVE: To review the result of the implementation of treatment protocol for post-chemotherapy sepsis in haematological malignancy patients. DESIGN: Case series with internal comparison. SETTING: Accident and Emergency Department, Queen Elizabeth Hospital, Hong Kong. PATIENTS: Febrile patients presenting to the Accident and Emergency Department with underlying haematological malignancy and receiving chemotherapy within 1 month of Accident and Emergency Department visit between June 2011 and July 2012. Similar cases between June 2010 and May 2011 served as historical referents. MAIN OUTCOME MEASURES: The compliance rate among emergency physicians, the door-to-antibiotic time before and after implementation of the protocol, and the impact of the protocol on Accident and Emergency Department and hospital service. RESULTS: A total of 69 patients were enrolled in the study. Of these, 50 were managed with the treatment protocol while 19 patients were historical referents. Acute myeloid leukaemia was the most commonly encountered malignancy. Overall, 88% of the patients presented with sepsis syndrome. The mean door-to-antibiotic time of those managed with the treatment protocol was 47 minutes versus 300 minutes in the referent group. Overall, 86% of patients in the treatment group met the target door-to-antibiotic time of less than 1 hour. The mean lengths of stay in the emergency department (76 minutes vs 105 minutes) and hospital (11 days vs 15 days) were shorter in those managed with the treatment protocol versus the historical referents. CONCLUSION: Implementation of the protocol can effectively shorten the door-to-antibiotic time to meet the international standard of care in neutropenic sepsis patients. The compliance rate was also high. We proved that effective implementation of the protocol is feasible in a busy emergency department through excellent teamwork between nurses, pharmacists, and emergency physicians.

RESUMO

The VISA-P is a questionnaire for assessing the severity of patellar tendinopathy (PT). Our study aim was to evaluate the equivalence of self-administration of the VISA-P online with the addition of risk factor questions to develop a tool suitable for high-volume remote use. A crossover study design with 107 subjects was used to determine equivalence between online and clinician administration. Three population groups were used to ensure construct validity. Online vs clinician administration revealed an intraclass correlation (ICC) of 0.79 [confidence interval (CI): 0.68-0.86] for the VISA-P with a systematic significant difference of 4.99, which is not clinically meaningful. Poor ICCs were seen for questions 7 and 8 of the VISA-P (0.37 and 0.47, respectively) in comparison with earlier questions. There were statistically significant differences between population groups for the VISA-P. The ICC for risk factor questions was excellent at 0.89 (CI: 0.84-0.93) with no mean difference (P = 1.00). The online questionnaire enables equivalent collection of VISA-P data and risk factor information and may well improve further with the suggested modifications to the instructions for questions 7 and 8. There is potential to use this questionnaire electronically to generate large databases in future research.

RESUMO

AIM: In view of the clinical importance of the adherence issues in schizophrenia management, a consensus group of experienced local psychiatrists and nurse specialists gathered to outline a number of consensus statements for clinicians to consider enhancing adherence in their patients. PROCESS: Prior to the consensus group meeting, three core members drafted eight statements on the issue of adherence in schizophrenia. Using a modified Delphi method, published literature and published guidelines regarding the management of schizophrenia were reviewed by the full panel during the group meeting. After discussion and reflection from each individual member of the consensus group, the eight statements were reworded and electronically voted on anonymously in two steps: acceptance on quality of evidence and practicability in implementation. RESULTS: After modifications of the original statements, there was very high overall level of agreement and acceptance (reaching international standard) on all the five areas of adherence within the eight statements of the finalised statement. CONCLUSIONS: The present consensus statements are the first in Hong Kong to address systematically adherence issues in schizophrenia management. They include areas on adherence assessment and definition, treatment strategies in enhancing adherence, and treatment considerations at specific phases of schizophrenia. They are tailored to be of practical utility in the local Hong Kong setting.
