RESUMO

OBJECTIVES: Implementation of an interprofessional program at Princess Margaret Cancer Centre, including nurse-led proactive calls to support patients with gynecologic cancers with malignant bowel obstruction, demonstrated improved outcomes compared with historical controls. The aim of the study was to convert the proactive calls into an electronic monitoring program to assess it's feasibility and scalability in patients with gynecologic cancers with or at risk of malignant bowel obstruction. METHODS: 'My Bowels on Track' smartphone application included weekly/biweekly electronic patient-reported outcomes (PROs), educational materials, and a secure messaging system. Based on PRO answers, an alerting system flagged patients with symptoms or uncompleted PROs. Nurses tracked and called patients on receiving clinical or compliance alerts. The primary objective was to assess adherence (≥70% PRO completion per patient considered an adherent patient) in the first 2 months on the program. A secondary objective was to assess the positive predictive value (PPV) of the alerts to trigger recommendations. RESULTS: Forty patients were enrolled between August 2021 and September 2022. Median age was 64.5 years (range 29-79 years). Primary diagnosis was ovarian (75%), endometrial (17.5%), or cervical (7.5%) cancer, and 92.5% of patients were receiving systemic therapy. Median duration on the program was 55 days (range 8-121 days). The 2-month adherence was 65% (95% CI 50% to 80%) and the overall adherence was 60% (95% CI 43% to 75%). Sixty-five symptom-related alerts (75% severe, 25% moderate) were reported in 60% (24/40) of patients. There were 59 recommendations triggered by the alerts. The PPV of the alerts to trigger actions was 72% (95% CI 58% to 82%). CONCLUSIONS: This pilot electronic malignant bowel obstruction monitoring program with real-time PRO assessment was feasible, and 65% of participants were adherent during the first 2 months on the program. The PRO response-based alerting system flagged concerning symptoms in 60% of participants, with a PPV of 72% to trigger nurse-led actions and/or management recommendations. TRIAL REGISTRATION NUMBER: NCT03260647.

RESUMO

Chronic myeloid leukemia (CML) management during pregnancy is challenging. In this retrospective study, hospital records of CML patients treated between 2000 and 2021 were screened to identify patients who tried to conceive/got pregnant (planned and unplanned) on TKIs (tyrosine kinase inhibitors)/were pregnant at CML onset/fathered a child. We found ninety-three pregnancies involving thirty-three women and thirty-eight men, and they were analyzed for the pregnancy outcomes and the strategies utilized for CML management during pregnancy and the pre-conception period. There were two women and four men with primary infertility and five women with secondary infertility. TKIs were discontinued before conception in four planned pregnancies and at the time of recognition of pregnancy in unplanned pregnancies (n = 21). Unplanned pregnancy outcomes were two miscarriages, eight elective terminations, and eleven live births. Planned pregnancies led to four healthy babies. Outcomes of pregnancies at CML onset (n = 17) were six live births, one stillbirth, five elective terminations, and five abortions. Except for one child with congenital micro-ophthalmia, no other child born to the women on TKI had any malformations. Thirty-eight men fathered 51 healthy children. All but two patients (one planned and one unplanned pregnancy) lost their hematological responses during pregnancy and gained their previous best response after restarting TKI. In women who were pregnant at CML onset, complete cytological remission (CCYR) was achieved between 7 and 24 months (median:14 months) after starting TKI. During pregnancy, intermittent hydroxyurea ± TKI (in the second and third trimesters) was used to keep WBCs less than 30,000/mm3. Outcomes of pregnancies in CML patients can be optimized with our approach. TKIs (Imatinib and Nilotinib) can be safely used in the second and third trimesters. Delayed initiation or interruption of TKI during pregnancy does not negatively affect response to TKIs.

RESUMO

INTRODUCTION: Data on the impact of desmoid type fibromatosis (DTF) on emotional distress and health-related quality of life (HRQoL) is sparse. METHODOLOGY: In this prospective cross-sectional study, patients with DTF and healthy controls were asked to fill the EORTC QLQ-C30, GAD-7, and PHQ-9 questionnaires. The objectives were to determine HRQoL, anxiety, and depression in patients with DTF. RESULTS: Two hundred four subjects (102 DTF patients and 102 healthy controls) were recruited. The median age of DTF patients at recruitment into the study was 31 years (IQR, 25-37 years). There was a female preponderance with a male:female ratio of 1:1.83. Appendicular skeleton and abdomen sites were most commonly involved in 59% and 22.5% respectively. About half (54%) of patients were currently on sorafenib and 41% were under active surveillance. The mean global health status in DTF patients was 65.58 ± 22.64, significantly lower than healthy controls. Similarly, DTF patients scored low on all functional scales except cognitive functioning. The symptom scale showed a significantly higher symptom burden of fatigue, pain, insomnia, and financial difficulties. Anxiety and depression was observed in 39.22% and 50% of DTF patients respectively. DTF patients had higher rates of mild, moderate, and severe anxiety and depression compared to healthy controls. CONCLUSION: DTF patients have significant symptom burden, poor functioning, and heightened anxiety and depression as compared to healthy controls. HRQoL, anxiety, and depression should be routinely used to assess symptom burden and treatment efficacy in DTF patients.

RESUMO

BACKGROUND: Haematopoietic stem cells (HSC) may act as a source of infection for the recipient due to manipulation at multiple levels from collection to infusion. Due to the high risk of contamination cultures are usually taken during multiple steps. The clinical significance of microbial contamination of HSC on the post-transplant course and the role of prophylactic antibiotics is relatively unknown. AIMS AND METHODS: The aim of our study is to investigate the incidence of microbial contamination of haematopoietic stem cell and to assess its impact on the post-transplant febrile neutropenia, engraftment kinetics, hospitalisation and day 100 mortality. Details of all patients admitted in the bone marrow transplantation unit of a tertiary care centre in India between January 2014 and December 2018 were collected from case records. RESULTS: Of the 1306 stem cell harvests from 503 patients sent for culture, 17 harvests (1.3%) were found to have a culture positive report. Sixteen patients had undergone autologous transplant. Multiple myeloma was most common indication of HSC transplant followed by Non-Hodgkin Lymphoma (NHL). Twelve of 17 HSC cultures were positive at the time of infusion and five were positive at the time of harvest. The five HSC that were culture positive at the time of harvest were culture negative at the time of infusion. Gram-positive organisms were isolated in six cultures and gram-negative in rest. All patients developed febrile neutropenia post-transplantation between day 1 and day 7. The median time of onset of fever was day +5 (1-7), the median duration of fever was 4 days (2-7), the median duration of antibiotic use was 11 days (9-16). Median day for neutrophil engraftment was 11 days (9-16), the median day for platelet engraftment was 14 days (10-25) and median duration of hospitalisation was 15 days (12-78). All patients were alive at day 100 of transplant. CONCLUSION: This study shows that there appears to be minimal impact of culture positive HSC on transplant related outcomes in terms of engraftment kinetics, duration of hospitalisation and day 100 mortality. Discarding of contaminated HSC may not be required, though on development of febrile neutropenia appropriate antibiotics should be administered based on sensitivity pattern of HSC culture. Larger prospective studies are needed to determine the clinical relevance of such contaminations. Emphasis should be laid on better infection control practices to minimise contamination rates.

RESUMO

OBJECTIVE: Acute laryngeal dystonia is one of the most life-threatening medication side effects in psychiatry. It is rare and predominately caused by the use of antipsychotics in at-risk individuals. Within days of a patient's initial presentation, several antipsychotics can be administered for the purposes of acute sedation and ongoing pharmacotherapy. In this case report, we describe a 27-year-old at-risk male, who developed acute laryngeal dystonia in the context of antipsychotic polypharmacy. CONCLUSION: Clinicians should take into account recent sedation and ongoing antipsychotic use in patients at risk of developing acute laryngeal dystonia. Awareness of this condition and prompt treatment with parenteral anticholinergic medication can be lifesaving.

RESUMO

BACKGROUND: Renal involvement was thought to occur more than 10 years after onset of diabetes, but recent studies provide evidence that it starts even in the pre-diabetes stage. However, there is no sensitive marker to detect these changes at such early stages. Novel urinary biomarkers have showed promising results in detection of early nephropathy in pre-diabetics. METHODS: A total of 91 subjects (diabetes 61 and pre-diabetes 30) were enrolled into the study. Urinary biomarkers such as urine Neutrophil Gelatinase-Associated Lipocalin (NGAL), urine Cystatin C and urine albumin-creatinine ratio (UACR) were estimated. Subjects were further divided in four groups on the basis of UACR: pre-diabetes with normoalbuminuria (21); pre-diabetes with microalbuminuria (9); diabetes with normoalbuminuria (37); and diabetes with microalbuminuria (24). The relationship of UACR, NGAL, and Cystatin C was estimated. RESULTS: Urine levels of NGAL and Cystatin C were significantly higher in microalbuminuria group compared to normoalbuminuria. UACR was positively correlated to urine NGAL-creatinine ratio (UNCR) and urine Cystatin C-creatinine ratio (UCCR) in both diabetes and pre-diabetes. On logistic regression odds ratio of UNCR to predict microalbuminuria in diabetes and pre-diabetes was 1.070 (p = 0.000) and 1.138 (p = 0.010), respectively. Area under curve was determined by ROC analysis, and UNCR was found to be better than UCCR for estimating microalbuminuria. CONCLUSION: Tubular damage may play major role in development of nephropathy in pre-diabetes. Newer markers like urine NGAL and Cystatin C are raised early in diabetes and pre-diabetes nephropathy.

RESUMO

Discovering new promising molecule candidates that could translate into effective drugs is a key scientific pursuit. However, factors such as the vastness and discreteness of the molecular search space pose a formidable technical challenge in this quest. AI-driven generative models can effectively learn from data, and offer hope to streamline drug design. In this article, we review state of the art in generative models that operate on molecular graphs. We also shed light on some limitations of the existing methodology and sketch directions to harness the potential of AI for drug design tasks going forward.

RESUMO

Translational research and the development of targeted therapies have transformed the therapeutic landscape in epithelial ovarian cancer over the last decade. However, recurrent ovarian cancer continues to pose formidable challenges to therapeutic interventions, necessitating innovative strategies to optimize treatment outcomes. Current research focuses on the development of pharmaceuticals that target potential resistance pathways to DNA repair pathways. However, the cost and toxicity of some of these therapies are prohibitive and majority of patients lack access to clinical trials. Metronomic chemotherapy, characterized by the continuous administration of low doses of chemotherapeutic agents without long treatment breaks, has emerged as a promising approach with potential implications beyond recurrent setting. It acts primarily by inhibition of angiogenesis and activation of host immune system. We here review the mechanism of action of metronomic chemotherapy, as well as its current role, limitations, and avenues for further research in the management of epithelial ovarian cancer.

RESUMO

Accurately assessing homologous recombination deficiency (HRD) to use as a predictive biomarker is an area of intense research in ovarian cancer. Validated assays have demonstrated utility in determining maintenance therapy following platinum sensitive chemotherapy. Novel functional assays promise the potential to reflect HRD in real time and predict response to PARP inhibitors.

RESUMO

Ovarian cancer is the leading cause of gynecological cancer death. Improved understanding of the biologic pathways and introduction of poly (ADP-ribose) polymerase inhibitors (PARPi) during the last decade have changed the treatment landscape. This has improved outcomes, but unfortunately half the women with ovarian cancer still succumb to the disease within 5 years of diagnosis. Pathways of resistance to PARPi and chemotherapy have been studied extensively, but there is an unmet need to overcome treatment failure and improve outcome. Major mechanisms of PARPi resistance include restoration of homologous recombination repair activity, alteration of PARP function, stabilization of the replication fork, drug efflux, and activation of alternate pathways. These resistant mechanisms can be targeted to sensitize the resistant ovarian cancer cells either by rechallenging with PARPi, overcoming resistance mechanism or bypassing resistance pathways. Augmenting the PARPi activity by combining it with other targets in the DNA damage response pathway, antiangiogenic agents and immune checkpoint inhibitors can potentially overcome the resistance mechanisms. Methods to bypass resistance include targeting non-cross-resistant pathways acting independent of homologous recombination repair (HRR), modulating tumour microenvironment, and enhancing drug delivery systems such as antibody drug conjugates. In this review, we will discuss the first-line management of ovarian cancer, resistance mechanisms and potential strategies to overcome these.

RESUMO

BACKGROUND: Carcinoma penis is a rare neoplasm, and the literature is scarce on long-term survival and its predictors. The aim of the study was to determine the clinical profile and management patterns, identify predictors of survival, and the impact of education and rural/urban dwelling on survival. METHODS: Patients with a histological diagnosis of carcinoma penis from January 2015 to December 2019 were included in the study. Demographics, clinical profile, education status, primary residence address, and outcomes were obtained from the case records. Distance from the treatment centre was obtained from the postal code. The primary objectives were to assess relapse-free survival (RFS) and overall survival (OS). The secondary objectives were to identify the predictors of RFS and OS and to determine the clinical profile and treatment patterns in patients with carcinoma penis in India. Time-to-event was calculated by Kaplan-Meir analysis and survival was compared by the log-rank test. Univariate and multivariable Cox regression analyses were used to find independent predictors of relapse and mortality. Logistic regression analyses to examine the associations of rural residence, education status, and distance from the treatment centre with the relapse adjusting for measured confounding variables. RESULTS: Case records of 102 patients treated during the above period were retrieved. The median age was 55.5 (interquartile range [IQR] 42-65 years). Ulcero-proliferative growth (65%), pain (57%), and dysuria (36%) were the most common presenting features. Clinical examination or imaging revealed inguinal lymphadenopathy in 70.6% of patients, however, only 42% of these lesions were pathologically involved. A total of 58.8% of patients were from rural areas, 46.9% had no formal education, and 50.9% had a primary residence ≥100 km from the hospital. Patients with lower education and rural households had higher TNM stages and nodal involvement. Median RFS and OS were 57.6 months (15.8 months to not reached) and 83.9 months (32.5 months to not reached), respectively. On univariate analysis tumor stage, involvement of lymph nodes, T stage, performance status, and albumin was predictive for relapse and survival. However, on multivariate analysis, the stage remained the only predictor of RFS and nodal involvement, and metastatic disease was a predictor of OS. Education status, rural habitation, and distance from the treatment centre were not predictors for relapse or survival. CONCLUSIONS: Patients with carcinoma have locally advanced disease at presentation. Rural dwellings and lower education were associated with the advanced stage but did not have a significant bearing on the survival outcomes. The stage at diagnosis and nodal involvement is the most important predictor of RFS and OS.

RESUMO

BACKGROUND: Sorafenib is currently one of the recommended treatments for symptomatic patients with desmoid-type fibromatosis (DTF). In this study, we aim to assess the clinical efficacy and tolerability of sorafenib in DTF patients. METHODOLOGY: Patients aged>18 years with a histological diagnosis of DTF and who have received sorafenib were enroled in this prospective observational study. Demographic data, clinical profile, the initial dose of sorafenib, treatment-related toxicities, dose modifications, and responses were recorded. The primary objective was to assess the objective response rate (ORR). The secondary objectives were to evaluate progression-free survival (PFS), tolerability, and adverse effects of sorafenib. Response assessment was based on response evaluation criteria in solid tumours 1.1 criteria. Adverse effects were graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 criteria. Time to event was calculated by Kaplan-Meier analysis, and survival was compared by log-rank test. Univariate and multivariable cox regression analysis were used to find independent predictors of relapse. RESULTS: A total of 104 patients were enroled in the study. The median age of the study population was 32 (range, 18-81) years, and 66.35% of patients were females. On response assessment, ORR was 46.1% and stable disease was observed in 31.7% patients. ORR was higher in the appendicular site (51.7%) compared to the abdominal site (27.2%). PFS at 1 and 2 years was 86.6% (79.6-92.7%) and 73.7% (62.4-82.8%), respectively. Two-thirds (66.6%) of patients had already received some form of treatment. At the time of analysis, 70 (67.3%) patients were continuing sorafenib. Only 4.8% stopped sorafenib due to progression, 10.5% due to intolerable adverse effects, and 17.3% due to other reasons. The common treatment-related toxicities were hand-foot skin reaction (HFSR) (89.4%), fatigue (79.8%), alopecia (70.1%), and diarrhoea (48.0%). In the patients with a starting dose of ≥400 mg (48.0% of patients), discontinuation was necessitated in 12% of patients, and further dose reduction was required in 58%, while only about 13% required dose reduction or discontinuation at a starting dose of 200 mg (51.9% of patients). Responses were not compromised due to lower starting doses. CONCLUSIONS: Sorafenib has good activity in DTF, but it is associated with significant toxicity. The adverse effect profile is distinct in Indian patients with higher HFSR and alopecia. Due to the high rate of dose reduction/discontinuation with a starting dose of 400 mg, a starting dose of 200 mg may be recommended in Indian patients.

RESUMO

OBJECTIVE: There are significant shortages in the psychiatric workforce in Australasia, particularly in the rural and remote regions of Australia and New Zealand. In response to these shortages, mental health services have recruited large numbers of overseas trained psychiatrists (OTP). These are specialist psychiatrists, trained and recognised as such in other countries. Our objective was to ascertain how OTPs experience the processes of commencing professional practice in Australasia. METHOD: OTPs were surveyed to identify the pathways to obtaining specialist registration and College Fellowship in Australasia and to explore their experiences as they engaged in this process. RESULTS: Although limited by a low response rate, the data does highlight a level of discontentment among those OTPs surveyed. The key issues identified related to the examination process, poor communication between different agencies (including the RANZCP), visa and residency related issues, medical board registration difficulties and notable differences between Australia and New Zealand. CONCLUSION: There is a negative perception among OTPs regarding the existing pathways to registration as specialist psychiatrists and the attainment of Fellowship. We submit that the RANZCP has a central and important role in resolving some of the underlying issues and supporting OTPs as vital and valued members of the workforce in Australia and New Zealand.

RESUMO

Follicular lymphoma (FL) originates from germinal center B cells, is the most prevalent form of indolent non-Hodgkin's lymphoma. Upfront management is based on stage, grade, and disease burden. Radiotherapy may be curative in limited disease while chemoimmunotherapy is preferred in advanced disease. Maintenance therapy is routinely administered but its role is debatable. Relapses are common and interval from initial therapy to relapse is most important prognostic factor for relapsed FL. Management of relapsed patients is based on the initial management, the interval from prior therapies, and the toxicity of available therapies. Multiple agents are available for patients after two or more lines of therapy, but sequencing remains poorly defined.

RESUMO

Endometrial cancer (EC) is common malignancy in women and its incidence is slowly on the rise. Accurate surgical staging, with aggressive cytoreduction when indicated, remains the most critical step in the treatment. Careful pathological evaluation and/or molecular risk stratification guides for proper systemic adjuvant radiotherapy ± chemotherapy. Recurrent and metastatic EC has dismal prognosis and palliative therapies (chemotherapy, hormonal therapy or radiation) forms the backbone of treatment. There is an unmet need of newer therapies to improve survival in such cases. A number of tyrosine kinase inhibitors are currently under evaluation. Recent data on therapeutic targeting of HER2 positive serous EC is exciting. Data on check point inhibitors particularly based on biomarker select population has raised hope for potentially effective treatment for women with high risk endometrial cancer .

RESUMO

Intravenous (IV) infusion is a common medical procedure which involves the administration of fluids directly into the blood stream typically through a vein in the arm of the patient. Though gravity fed IV-drip is a safe, effective and an affordable tool, yet several complications can arise in its usage and thus requires constant monitoring. In this paper, a solution is presented for infusion monitoring based on detection of drops falling through the drip chamber. The system presented here accurately tracks the fluid flow and assists the users in monitoring the infusion sessions. The system generates alarm upon detecting significant deviation from set drip rate. The system keeps track of total volume infused and alerts when a desired volume is about to be administered. The device offers a solution to reduce the risks associated with the IV infusion therapy especially in low-resource setting and provide peace of mind to caregivers.

RESUMO

Background: Complicated urinary tract infection (cUTI) is the one which is associated with structural and functional abnormalities of the urinary tract, thus increasing the risk of infection and failure of therapy. Aim: This study aims to determine the risk factors, changing trends in etiology, current treatment options, and outcomes in cUTI. Materials and Methods: This prospective observational study was done on patients presenting with cUTI. Hematological, biochemical workup, urine routine, urine culture, blood culture, ultrasonography, and wherever necessary computerized tomography of the genitourinary tract was done. The medical/surgical interventions and outcomes in these patients were recorded. Results: A total of 100 patients were enrolled in the study. Diabetes mellitus was the most common risk factor present in 53%. The most common organism isolated in urine culture was Escherichia coli (48%) followed by Klebsiella pneumoniae (19%) and similar trend but lesser positive yield was there in blood culture (Escherichia coli - 26% followed by Klebsiella pneumoniae - 3%). The organisms were most susceptible to colistin/polymyxin (100%) followed by carbapenems (88%), and later were the most commonly used empirical antibiotics in our study, yielding 95% survival rate. Surgical interventions (percutaneous/endourological) were required in 28%, renal replacement therapy in 14%, intensive care in 40% and mechanical ventilation in 10%, with 4% overall mortality at the end of 1-month follow-up. The mean duration of hospital stay was 9.1 ± 2.7 days. Conclusion: Escherichia coli was the most common organism causing cUTI, with diabetes being the most common risk factor. Most of the patients were treated with carbapenems with excellent survival outcomes.

RESUMO

Background: Anorectal melanoma (AM) is a rare subtype of melanoma. Aim: To study the clinic-pathologic features and outcomes in patients with AM. Materials & methods: Clinical, pathologic findings and outcomes of patients with AM were recorded. Results: Twenty-seven patients with AM were identified with median age of 57 years. Most patients presented in stage III (44.4%). Lymph node involvement was seen in 70.4%. The response to chemotherapy and immunotherapy was 16.6 and 25.0%, respectively. At a median follow up of 11 months, median overall survival was 30 months. Ballantine stage 3 and weight loss at presentation were predictors of poor survival. Conclusion: AM presents at an advanced stage with lymph node and distant metastasis.

RESUMO

Background: One fifth of patients with epithelial ovarian cancers (EOC) present at an early stage (FIGO stage I & II). However, there is scarcity of literature on the outcomes and its predictors. The aim of the study was to assess relapse free survival (RFS), overall survival (OS) and its predictors in early stage EOC. Patients and Methods: In this retrospectively study, we included all patients with early-stage EOC diagnosed between January 2010 and December 2018. Patients with synchronous malignancies were excluded. Clinical profile, clinico-pathological characteristics and treatment details were recorded. Patient underwent initial surgery followed by adjuvant chemotherapy in high-risk disease. Patients with stage IC, or stage II or clear cell histology or high-grade histology irrespective of stage/histological subtype were defined as high-risk disease. Fertility sparing surgery (FSS) [unilateral salpingo-oopherectomy with complete surgical staging] was performed in patient willing to preserve fertility. Primary objective was to assess RFS and OS in all patients with early stage EOC. Secondary objectives were to assess RFS and OS in early stage EOC with high-risk disease, predictors of RFS and OS, and outcomes of FSS. Survival probabilities were estimated according to Kaplan-Meier and compared by the log rank test. Cox's regression model was used to analyze the significance of various factors affecting relapse free survival (RFS) and overall survival (OS). Results: 195 patients with early stage EOC were recruited with median age of 47 years (range, 16-80 years). FIGO stage I and stage II were seen in 72 % and 18 % patients respectively. Serous subtype was reported in 58 % and high-grade histology in 66 %. 184 patients (94.0%) underwent optimal staging surgery, including 27 (14%) with fertility sparing surgery (FSS). 133 (91.7 %) of 145 patients with high-risk disease received adjuvant chemotherapy (paclitaxel and carboplatin), while 12 (8.3 %) patients opted to remain on observation. At median follow up of 56 months (95 % CI, 46-64 months), 49 (25 %) patients relapsed [including 3 of 27 (11.1 %) who underwent FSS], 18 patients died of progressive disease, while 31 patients were alive and disease free. Estimated OS at 5 years is 87.6 % (95 % CI 79.9-92.5) and RFS is 73.2 % (95 % CI 64.7-80.0). On multivariate analysis tumor grade was predictive of RFS (HR 2.9, p < 0.04) and OS (HR 9.4, p < 0.02). Conclusions: This study confirms the excellent outcome for patients with early stage EOC. Histological grade of tumor is a significant predictor of OS and RFS. FSS is feasible in selected patients with early EOC.
