Abstract
PURPOSE/OBJECTIVE(S) Hypofractionated radiation therapy (HFRT) is an increasingly utilized treatment option for patients with lung cancers unamenable to stereotactic body radiotherapy (SBRT). Conventional HFRT (C-HFRT) is often prescribed to 60 Gy in 15 fractions, which has a lower biologically effective dose (BED10 of 84.0) than SBRT. We compared outcomes of patients treated with a dose-escalated HFRT regimen (DE-HFRT, 72 Gy in 18 fractions, BED10 of 100.8) to those treated with C-HFRT. We aimed to evaluate local control (LC), overall survival (OS), and grade 3+ toxicity between patients who received C-HFRT vs. DE-HFRT as we hypothesized DE-HFRT may be superior/equivalent to C-HFRT. MATERIALS/METHODS A database was created of all patients at our institution who received either thoracic C-HFRT or DE-HFRT between 2013 and 2020. Baseline variables were compared by chi-square analysis and logistic regression. We analyzed the association between treatment regimens with LC and OS (log-rank test and Cox proportional hazards regression), as well as grade 3+ toxicity. RESULTS A total of 107 patients were included, among whom 55 (51.4%) received C-HFRT and 52 (48.6%) received DE-HFRT. Median age was 73, 88.8% of patients had non-small cell lung cancer, 81.3% received lung-only treatment, and 52.3% had an ultra-central tumor location (within 1 cm of proximal tracheobronchial tree, esophagus, or heart). Patients with DE-HFRT were more likely to have lung-only treatment (92.3% vs. 70.9%, p = 0.005) and stage I disease (47.1% vs 24.1%, p = 0.01) than those with C-HFRT, but had a similar proportion of ultra-central tumors (57.1% vs. 54.9%, p = 0.82). Patients with DE-HFRT had a non-statistically significant trend towards higher LC (2-year 81.0% vs. 72.3%, 3-year 77.3% vs 52.3%, HR 0.53 [95% CI 0.26-1.09], p = 0.09) and OS (2-year 61.3% vs. 44.8%, 3-year 44.9% vs 33.9%, HR 0.68 [95% CI 0.41-1.11], p = 0.13) compared to those with C-HFRT. Similar findings were noted among those with lung-only treatment. Among those with ultra-central tumors, patients with DE-HFRT had statistically significantly higher LC (2-year 86.6% vs 71.2%, 3-year 86.6% vs 42.2%, HR 0.26 [95% CI 0.08-0.84] p = 0.02) and a non-statistically significant trend towards higher OS (2-year 63.8% vs 40.0%, 3-year 46.2% vs 31.1% HR 0.55 [95% CI 0.28-1.09] p = 0.09) compared to those with C-HFRT. There was no statistically significant difference in grade 3+ toxicities between DE-HFRT and C-HFRT (15.4% vs. 10.9%, OR 1.48 [95% CI 0.47-4.61], p = 0.49). CONCLUSION We noted promising local control and overall survival for patients treated with 72 Gy in 18 fractions compared to 60 Gy in 15 fractions, especially among those with ultra-central tumors. Grade 3+ toxicities were not significantly higher for patients undergoing dose escalation. Hence, our findings suggest that DE-HFRT to the lung is a safe and effective treatment regimen for highly selected patients who cannot undergo SBRT.

Benefit of inhalation aromatherapy as a complementary treatment for stress and anxiety in a clinical setting – A systematic review. Complement Ther Clin Pract 2023; 52:101750. [PMID: 37031643 DOI: 10.1016/j.ctcp.2023.101750] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 03/07/2023] [Accepted: 03/26/2023] [Indexed: 04/08/2023]
Abstract
OBJECTIVE The purpose of this systematic review is to ascertain the impact of inhalation aromatherapy on stress and anxiety in clinical settings. METHODS A search strategy was developed using various databases. Randomised Controlled Trials (RCTs) as well as single and double-blind pilot clinical studies (non-RCT) using inhalation aromatherapy with an essential oil blend or a single essential oil were examined. All studies included a control intervention and use of a validated measurement tool. The time period under review was years 2000-2021. Due to the high level of heterogeneity and element of bias, a narrative synthesis was conducted. RESULTS The search strategy initially retrieved 628 studies and through application of the selection criteria and the removal of duplicates, 76 studies were selected for review with a total of 6539 patients. In 42% of the RCTs, physiological measures including vital signs and/or salivary cortisol were used in addition to questionnaires. Over 70% of the studies reported a positive effect on anxiety levels in the aromatherapy intervention groups compared with the control. However, in many cases this is limited by the absence of safety data, imprecise reporting of plant species and dosage of essential oil. CONCLUSION Inhalation aromatherapy has the potential to reduce stress and anxiety with data emerging to further support this result across a wide modality of clinical treatments. However, there is a clear need for the development of standard protocols for research in this area, generating measurable results which will create the opportunity for more rigorous evidence-based outcomes.

Abstract
Abstract
Background/Introduction
Myocardial work and work efficiency are new parameters for assessing left ventricular function. They have been shown to have value in a range of clinical settings but have not previously been applied to exercise stress echocardiography.
Purpose
We aim to characterize the normal myocardial work and work efficiency response to exercise in a mixed population and determine if myocardial work could be used to identify patients with inducible ischaemia.
Methods
Patients were retrospectively enrolled from an existing database of exercise stress echocardiography. Inclusion criteria were a clinical indication of possible ischemia and technical suitability to calculate myocardial work. Exclusion criteria were abnormal baseline left ventricular function or inadequate image quality. Echocardiograms positive for ischaemia were defined by independent visual assessment and compared with angiographic findings where available. Myocardial work and work efficiency were calculated using a proprietary algorithm.
Results
A total of 177 patients met inclusion criteria, 117 were excluded leaving 40 normal and 20 positive tests for analysis. During normal exercise global work increased 54% and efficiency remained at 96%. Segmental work showed a basal to apical gradient which became more prominent at peak exercise. In patients with inducible ischaemia during exercise there was a significant difference in response; work decreased by 1.9% and efficiency dropped to 87%. Receiver operating characteristic curve for myocardial work had an area under the curve of 0.94. Youden's J statistic suggested an optimum cut point of a 25% increase in work to define a normal test.
Conclusion
During normal exercise myocardial work increased and efficiency remained unchanged, however during exercise induced ischaemia both myocardial work and efficiency decreased. We have demonstrated that myocardial work can be applied to stress echocardiography to identify ischemia but the utility of this remains uncertain. Further research compared to an objective measure of functional ischemia is needed.

Incidence rate, predictors and outcomes of interruption of HIV care: nationwide results from the Belgian HIV cohort. HIV Med 2020; 21:557-566. [PMID: 32627351 PMCID: PMC7540395 DOI: 10.1111/hiv.12901] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/28/2020] [Indexed: 11/30/2022]
Abstract
Objectives We aimed to study the incidence rate, predictors and outcomes of HIV care interruption (HCI) in Belgium. Methods We analysed data for adult patients with at least two HIV care records in the Belgian HIV cohort between 1 January 2007 and 31 December 2016. An HCI episode was defined as 1 year without an HIV care record. The HCI incidence rate was analysed using Poisson regression, return to HIV care using a cumulative incidence function with death as a competing risk, and viral load (VL) status upon return to HIV care using logistic regression. Results We included 16 066 patients accounting for 78 625 person‐years of follow‐up. The incidence rate of HCI was 5.3/100 person‐years [95% confidence interval (CI) 5.1–5.4/100 person‐years]. The incidence of return to HIV care after HCI was estimated at 77.5% (95% CI 75.7–79.2%). Of those who returned to care, 43.7% had a VL ≤ 200 HIV‐1 RNA copies/mL, suggesting care abroad or suboptimal care (without an HIV‐related care record) in Belgium during the HCI, and 56.3% returned without controlled VL and were therefore considered as having experienced a real gap in HIV care; they represented 2.3/100 person‐years of follow‐up. Factors individually associated with HCI were no antiretroviral therapy (ART) uptake, lower age, injecting drug use, non‐Belgian nationality, male gender, not being a man who has sex with men, a shorter time since HIV diagnosis, no high blood pressure and CD4 count < 350 cells/µL. Conclusions This study highlights the need to investigate return to care and viral status at return, to better understand HCI. Identified predictors can help health care workers to target patients at higher risk of HCI for awareness and support.

Abstract
Abstract
Objectives:
Addition of pertuzumab to trastuzumab and docetaxel (THP) results in significant clinical benefits for women with HER2-positive metastatic breast cancer. Despite evidence of important overall survival and quality of life improvements, for the Brazilian patients depending on the public health system chemotherapy alone (CT) remains the standard treatment. Previous request for trastuzumab incorporation was denied by Brazilian Ministry of Health (MoH) due to high individual costs.
In an innovative way, the Brazilian Society of Clinical Oncology made a price negotiation directly with the pharmaceutical company, aiming to propose a formal request for the incorporation of these technologies to the National Committee for Health Technology Incorporation (CONITEC).
Our objective was to evaluate the cost-effectiveness of THP versus CT in patients with HER2-positive advanced breast cancer, under the perspective of the Brazilian public health system.
Methods:
A cost-effectiveness analysis was conducted using a Markov model over a lifetime horizon. The model considers three health states: 1st-line treatment without progression; disease progression (with chemotherapy or best supportive care) and death. Transition probabilities and mortality rates were extracted from randomized studies. Costs of standard chemotherapy, complications, and surveillance were obtained from price tables regulated by the MoH. Pertuzumab and trastuzumab prices were those negotiated with the manufacturing company. Benefits are presented in life-years (LY) and costs in USD (using exchange rate for Brazilian Real to USD = 3.50). The relation between costs and benefits were used to present the incremental cost-effectiveness ratio (ICER) per life-year saved. We have performed one-way deterministic sensitivity analyses with cost of monoclonal antibodies to define the ideal price in Brazil.
Results:
Patients with HER2-positive metastatic breast cancer treated with CT were projected to have 1.87 LY, with a total cost of $12,118. THP was projected to increase the life expectancy of these patients by 1.48 years, with an incremental cost of $63,685 per patient. Thus, the ICER was $42,893 per LY-gained.
Conclusions:
The World Health Organization recommendation of three times gross domestic product per capita have defined our cost-effectiveness threshold. Despite the discount price, at a willingness-to-pay (WTP) threshold of $25,615 per LY, THP is not a cost-effective strategy compared to CT. An additional reduction around 58.67% in the pertuzumab price would be necessary to make THP cost-effective in Brazil.
Discussion about the incorporation of trastuzumab to CT using the discount prices is in progress.

Transmission of HIV Drug Resistance and the Predicted Effect on Current First-line Regimens in Europe. Clin Infect Dis 2015; 62:655-663.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

Good continuum of HIV care in Belgium despite weaknesses in retention and linkage to care among migrants. BMC Infect Dis 2015; 15:496.

Abstract
Background The Belgian HIV epidemic is largely concentrated among men who have sex with men and Sub-Saharan Africans. We studied the continuum of HIV care of those diagnosed with HIV living in Belgium and its associated factors. Methods Data on new HIV diagnoses 2007–2010 and HIV-infected patients in care in 2010–2011 were analysed. Proportions were estimated for each sequential stage of the continuum of HIV care and factors associated with attrition at each stage were studied. Results Of all HIV diagnosed patients living in Belgium in 2011, an estimated 98.2 % were linked to HIV care, 90.8 % were retained in care, 83.3 % received antiretroviral therapy and 69.5 % had an undetectable viral load (<50 copies/ml). After adjustment for sex, age at diagnosis, nationality and mode of transmission, we found lower entry into care in non-Belgians and after preoperative HIV diagnoses; lower retention in non-Belgians and injecting drug users; higher retention in men who have sex with men and among those on ART. Younger patients had lower antiretroviral therapy uptake and less viral suppression; those with longer time from diagnosis had higher ART uptake and more viral suppression; Sub-Saharan Africans on ART had slightly less viral suppression. Conclusions The continuum of HIV care in Belgium presents low attrition rates over all stages. The undiagnosed HIV-infected population, although not precisely estimated, but probably close to 20 % based on available survey and surveillance results, could be the weakest stage of the continuum of HIV care. Its identification is a priority along with improving the HIV care continuum of migrants.

Abstract
Objectives In 2011, a consensus was reached defining “late presenters” (LPs) as individuals presenting for care with a CD4 count < 350 cells/μL or with an AIDS‐defining event, regardless of CD4 count. However, a transient low CD4 count is not uncommon in recent infections. The objective of this study was to investigate how measurements of late presentation change if the clinical stage at the time of diagnosis is taken into account. Methods Case surveillance data for newly diagnosed patients in Belgium in 1998–2012 were analysed, including CD4 count at diagnosis, the presence of AIDS‐defining events, and recent infections (< 6 months) as reported by clinicians in the case of acute illness or a recent negative test. First, proportions of LPs were calculated according to the consensus definition. Secondly, LPs were reclassified as “nonlate” if infections were reported as recent. Results A total of 7949 HIV diagnoses were included in the study. Recent infections were increasingly reported over time, accounting for 8.2% of new infections in 1998 and 37.5% in 2012. The consideration of clinical stage significantly modified the proportion of LPs: 18.2% of men who have sex with men (MSM) diagnosed in 2012 would be classified as LPs instead of 30.9% using the consensus definition (P < 0.001). The proportion of patients misclassified as LPs increased significantly over time: 5% in MSM in 1998 vs. 41% in 2012. Conclusions This study suggests that low CD4 counts in recent infections may lead to overestimation of late presentation when applying the consensus definition. The impact of transient CD4 count on late presentation estimates should be assessed and, if relevant, the introduction of clinical stage in the definition of late presentation should be considered.

Abstract
A total of 1055 nucleotide sequences obtained from HIV patients diagnosed in 2008 and 2009 in Belgium were included in this prevalence study. The study population is a group of patients whose visit was considered by the clinician as the first contact with a Belgian AIDS reference centre or with another clinical centre experienced in HIV care. Prevalences of surveillance drug resistance mutations (SDRM) of 11·7% (47/394) and 11·0% (73/661) were observed in 2008 and 2009, respectively. The highest level of SDRM was observed towards nucleoside reverse transcriptase inhibitors (NRTIs) (7·8%), followed by the non-nucleoside reverse transcriptase inhibitors (NNRTIs) (4·2%) and Protease inhibitors (PIs) (2·3%). A potential clinical impact of the SDRM was demonstrated when using the current first-line therapy. A particularly high prevalence of SDRM was observed among intravenous drug users (IDUs) (29·4%). Reanalysis and comparing the data from previous Belgian studies using similar interpretation algorithms could not reveal a significant trend in SDRM prevalence over the last 5 years.

Abstract
In Belgium, individual laboratory and treatment data of all HIV-infected patients seen in the 9 AIDS Reference Centres and 7 AIDS Reference Laboratories are collected prospectively since 2006. We present here an analysis of patients recorded in the cohort database between 1st of January 2006 and 31st of December 2008. During that period, 11982 patients were under medical follow-up in Belgium. Sixty-one percent of the patients were male and the median age was 39.8 at the time of first recorded viral load. Among the patients whose nationality or probable mode of transmission was recorded, nearly half (48.0%) were Belgian and 38.3% originated from Sub-Saharan Africa; heterosexual contacts were reported in the majority of cases (56.0%) followed by homosexual contacts (35.3%). A total of 145 deaths were reported. Around three quarters of the patients were on ART. The median CD4 cell count rose from 470 cells/mm3 in 2006 to 501 cells/mm3 in 2008. This cohort enabled us to obtain comprehensive information on the numbers and characteristics of HIV-infected patients currently being followed up in Belgium, and on trends in antiretroviral therapy and biological results. This will serve for planning purposes, evaluation of access to care and as a source of information for further studies.

Abstract
Lymphogranuloma venereum, caused by the L serovars of Chlamydia trachomatis, emerged in Europe in 2003 and a series of outbreaks were reported in different countries. The infection presents as a severe proctitis in men who have sex with men, many of whom are co-infected with HIV and other sexually transmitted infections. This paper reviews the number of cases reported over a five year period, from 2003 to 2008, from countries that were part of the European Surveillance of Sexually Transmitted Infections (ESSTI) network. Reports were received from Belgium, Denmark, France, Germany, the Netherlands, Portugal, Spain, Sweden, and the United Kingdom. It appears that after five years the characteristics of the patients infected has overall remained unchanged, although the total number of cases has increased and more countries in Europe have now identified cases of LGV.

Abstract
Belgium is currently experiencing an upward trend in the number of new HIV diagnoses characterised by a continuous increase in the number of cases among men who have sex with men (MSM). Based on surveillance data, in the past decade the yearly number of newly diagnosed HIV cases in MSM increased more than threefold, from 101 cases diagnosed in 1999 to 332 cases in 2008. During this period, the majority of new HIV infections in MSM were diagnosed among Belgian citizens (72%), followed by other European nationalities (13%). The increase in HIV diagnoses does not reflect an increase in HIV testing since the number of tests performed nationwide remained remarkably stable over time. The steady increase in the number of newly diagnosed HIV cases among MSM, and the high proportion of MSM among HIV-positive patients co-infected with other sexually transmitted infections (STI) (95.6% in 2008) indicate increases in unsafe sex practices in this group. Development of behavioural surveillance and more qualitative research on reasons for unsafe sex are needed in order to develop more effective prevention strategies.

Abstract
In Belgium, three registration systems collect epidemiological information on N. gonorrhoeae infections. The descriptive analysis of the data presented in this article allows describing the epidemiology of N. gonorrhoeae infections in Belgium in terms of trends in time, describing the characteristics of the patients, and providing information on resistance to antibiotics. The results on the incidence of N. gonorrhoeae infections show an important increase since the year 2000, and this increase is even more pronounced between 2005 and 2006. The majority of the patients reside in big cities, mainly in the district of Antwerp and in the Brussels-Capital region. Among the N. gonorrhoeae specimens that were sent to the reference laboratory, the proportion of specimens resistant to ciprofloxacine increases each year; this proportion reaches 61.4% in 2006. The increase in the incidence of N. gonorrhoeae infections and in antimicrobial resistance is also observed in other European countries. The increase in incidence may be partly related to the important increase of resistance to ciprofloxacine. It is very important to continue the surveillance of antimicrobial resistance, to adapt treatment in function of the recent evolutions and to inform physicians at a regular basis. The results show that homo- and bisexual men are most at risk for N. gonorrhoeae infections. The prevention campaigns for sexually transmitted infections and screening policy have to be reinforced, particularly among homo- and bisexual men.

Abstract
From 1990 through 2002, 25,250 anonymous and free HIV tests were performed at a testing site, which carried out the majority (85%) of anonymous testing in Belgium. During the same period, approximately 7.3 million confidential tests were registered nationwide. The rate of new HIV infections diagnosed at the anonymous testing site was 11.1/1000 tests; it was significantly higher than the rate observed among confidential tests (relative risk = 7.41; P < 0.0001). New HIV cases diagnosed through anonymous testing include a higher proportion of young adults (42.0% versus 32.5% in confidential testing; P < 0.001) and a higher proportion of men who have sex with men (32.7% vs. 25.9% in confidential testing; P < 0.02). Anonymous and free HIV testing was particularly sought by persons with higher infection risk, and efficiently contributed to HIV diagnosis in this population. Anonymous and free testing should be and remain an accessible alternative integrated in HIV testing policies.

Abstract
BACKGROUND Malignant melanoma, one of the most aggressive of all skin cancers, is increasing in incidence throughout the world. Surgery remains the cornerstone of curative treatment in earlier stages. Metastatic disease is incurable in most affected people, because melanoma does not respond to most systemic treatments. A number of novel approaches are under evaluation and have shown promising results, but they are usually associated with increased toxicity and cost. The combination of chemotherapy and immunotherapy has been reported to improve treatment results, but it is still unclear whether evidence exists to support this choice, compared with chemotherapy alone. No language restrictions were imposed. OBJECTIVES To compare the effects of therapy with chemotherapy and immunotherapy (chemoimmunotherapy) versus chemotherapy alone in people with metastatic malignant melanoma. SEARCH STRATEGY We searched the Cochrane Skin Group Specialised Register (14 February 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2005), MEDLINE (2003 to 30 January 2006 ), EMBASE (2003 to 20 July 2005) and LILACS (1982 to 20 February 2006). References, conference proceedings, and databases of ongoing trials were also used to locate trials. SELECTION CRITERIA All randomised controlled trials that compared the use of chemotherapy versus chemoimmunotherapy on people of any age, diagnosed with metastatic melanoma. DATA COLLECTION AND ANALYSIS Two authors independently assessed each study to determine whether it met the pre-defined selection criteria, with differences being resolved through discussion with the review team. Two authors independently extracted the data from the articles using data extraction forms. Quality assessment included an evaluation of various components associated with biased estimates of treatment effect. Whenever possible, a meta-analysis was performed on the extracted data, in order to calculate a weighed treatment effect across trials. MAIN RESULTS Eighteen studies met our criteria and were included in the meta-analysis, with a total of 2625 participants. We found evidence of an increase of objective response rates in people treated with chemoimmunotherapy, in comparison with people treated with chemotherapy. Nevertheless, the impact of these increased response rates was not translated into a survival benefit. We found no difference in survival to support the addition of immunotherapy to chemotherapy in the systemic treatment of metastatic melanoma, with a hazard ratio of 0.89 (95% CI 0.72 to 1.11, p=0.31). Additionally, we found increased hematological and non-hematological toxicities in people treated with chemoimmunotherapy. AUTHORS' CONCLUSIONS We failed to find any clear evidence that the addition of immunotherapy to chemotherapy increases survival of people with metastatic melanoma. Further use of combined immunotherapy and chemotherapy should only be done in the context of clinical trials.
