Oropharyngeal squamous cell carcinoma (SCC) is a common type of head and neck cancer often linked to tobacco, alcohol use, and, in youngers, HPV infection. Standard care for locally advanced SCC involves radiotherapy (RT) and cisplatin, (total doses of 66–70Gy in 30–35fractions). However, some patients with significant comorbidities cannot tolerate chemotherapy, requiring alternative approaches. We present a case of a 66-year-old male with p16-negative oropharyngeal SCC and bulky cervical nodal metastasis, ineligible for chemotherapy.
Materials & Methods:
The patient was treated using adaptive volumetric modulated arc therapy (VMAT) with simultaneous integrated boost (SIB) and central gross tumor volume (GTV) dose escalation. This approach delivered up to 72Gy to the central GTV in 30 fractions; 66 Gy in 30 fractions to the high-risk area; 60Gy in 30 fractions to the intermediate-risk area; 54 Gy in 30 fractions to the low-risk area.
Results:
An epithelolysis (grade 3) led to a four-day treatment pause. A mid-treatment CT showed tumor shrinkage, reducing the nodal GTV volume from 107to 33cc, prompting adaptive planning to optimize dose distribution and reduce toxicity. The patient completed RT without further interruptions. At six months post-treatment, no recurrence or severe toxicities were detected and four years post-treatment, the patient remains in complete remission without significant late toxicity.
Conclusions:
This case demonstrates the effectiveness of VMAT with SIB in delivering accelerated radiotherapy to a bulky nodal lesion in a patient with p16-negative oropharyngeal SCC unfit for chemotherapy; This allowed for tumor control while minimizing exposure to critical structure.
Our study aim was to identify high-risk areas of neonatal mortality associated with bacterial sepsis in the state of São Paulo, Southeast Brazil. We used a population-based study applying retrospective spatial scan statistics with data extracted from birth certificates linked to death certificates. All live births from mothers residing in São Paulo State from 2004 to 2020 were included. Spatial analysis using the Poisson model was adopted to scan high-rate clusters of neonatal mortality associated with bacterial sepsis (WHO-ICD10 A32.7, A40, A41, P36, P37.2 in any line of the death certificate). We found a prevalence of neonatal death associated with bacterial sepsis of 2.3/1000 live births. Clusters of high neonatal mortality associated with bacterial sepsis were identified mainly in the southeast region of the state, with four of them appearing as cluster areas for all birth weight categories (<1500 g, 1500 to <2500 g and ≥ 2500 g). The spatial analysis according to the birth weight showed some overlapping in the detected clusters, suggesting shared risk factors that need to be explored. Our study highlights the ongoing challenge of neonatal sepsis in the most developed state of a middle-income country and the importance of employing statistical techniques, including spatial methods, for enhancing surveillance and intervention strategies.
The geochemistry of lake sediments provides valuable information on environmental conditions and geochemical processes in polar regions. To characterize geochemical composition and to analyse weathering and provenance, 26 lakes located in six islands of the South Shetland Islands (SSI) and James Ross Archipelago (JRA) were analysed. Regarding major composition, the studied lake sediments correspond to ferruginous mudstones and to a lesser extent to mudstones. The weathering indices indicate incipient chemical alteration (Chemical Index of Alteration = 52.6; Plagioclase Index of Alteration = 57.6). The La-Th-Sc plot shows different provenance signatures. SSI lake sediments correspond to oceanic island arcs, whereas those of JRA denote a signal of continental arcs with mixed sources. In James Ross Island lake sediments are of continental arcs (inland lakes), oceanic island arcs (coastal lakes) and a middle signature (foreland lakes). Multi-elemental analysis indicates that the sediments are enriched from regional basalts in Ba, Rb, Th, Cs and U (typical of silica-rich rocks) and depleted in Cr and Co due to mafic mineral weathering. The geochemical signals identified by principal component analysis enable us to group the sediments according to the studied islands and their geomorphological characteristics. This study underlines the importance of knowing the geochemical background levels in pristine lake sediments to evaluate potential future anthropogenic effects.
The objective of this article is to describe the profile of the population attended to by the palliative geriatrics clinic and to evaluate the symptomatic control derived from the care provided.
Methods
During 2017 a model based on a holistic approach was implemented, in this model the team geriatric palliative care plays a fundamental role by being part of the palliative care team and functioning as a liaison with the oncology team and other required services. We outlined the profile of 100 patients aged 70 and older seen between 2017 and 2019 at our geriatric palliative care clinic. Descriptive statistics were used. In addition, the symptoms and the care clinic model effect on the symptomatic control were analyzed, as well as the complexity of patients in palliative care with IDC-Pal.
Results
The patients median age was 83.5 years. Patients were classified by type of management: 47% within the supportive care group and 53% with palliative care only; 58% had metastatic disease and 84% presented at least 1 comorbidity. Frailty was observed in 78% and a Karnofsky scale of 60 or less was observed in 59% of the overall population.
Significance of results
Elderly cancer patients have a complex profile and may have multiple needs. Integrating geriatric palliative care can help to provide better and personalized care along with symptomatic control. Further studies are required to establish the ideal care model for these patients. Importantly, a personalized treatment with a geriatric palliative care specialist is a key element.
To investigate the impact of early vs. late palliative care (PC) on the frequency of admissions to acute hospital settings and the utilization of end-of-life (EoL) interventions in cancer decedents.
Methods
In this single-center, cross-sectional study, we examined the frequency of intensive care unit (ICU) and emergency department (ED) admissions among adult cancer decedents between 2018 and 2022 in a referral hospital in México. Additionally, we assessed EoL medical interventions, categorizing patients into 3 groups: those who received early PC (EPC), late PC (LPC), and those who did not receive PC (NPC).
Results
We analyzed data from 1762 patients, averaging 56 ± 16.3 years old, with a predominant representation of women (56.8%). PC was administered to 45.2% of patients, but EPC was limited to only 12.3%. The median time from the initiation of PC to death was 5 days (interquartile range: 2.0–31.5). Hematological malignancies were the most prevalent, affecting 21.5% of patients. EPC recipients demonstrated notable reductions in ICU and ED admissions, as well as diminished utilization of chemotherapy, radiotherapy (RT), antibiotics, blood transfusions, and surgery when compared to both LPC and NPC groups. EPC also exhibited fewer medical interventions in the last 14 days of life, except for RT.
Significance of results
The findings of this study indicate that a significant proportion of EoL cancer patients receive PC; however, few receive EPC, emphasizing the need to improve accessibility to these services. Moreover, the results underscore the importance of thoughtful deliberation regarding the application of EoL medical interventions in cancer patients.
Maternal obesity may trigger long-term neurodevelopmental disorders in offspring. Considering the benefits of the Brazil nut (Bertholletia excelsa H.B.K.), a rich source of nutrients such as selenium, this study aimed to evaluate its effect on the behavior of obese rat offspring and its relationship with oxidative stress. From 60 days of age until weaning, female Wistar rats were fed a high-fat diet (mHF) or an HF diet supplemented with 5% Brazil nut (mHF/BN), while control mothers (mCTL) were fed a standard diet or a standard diet supplemented with 5% Brazil nut (mBN). Male pups received a standard diet throughout life and, at 30 and 90 days old, were subjected to behavioral tasks to evaluate anxiety and cognition. Biochemical evaluations were performed at 90 days of age. No alterations were observed in the anxiety behavior of the offspring. However, the offspring of the mHF group (oHF) exhibited impaired short-term memory at 30 and 90 days of age and impaired long-term memory at 30 days. Short-term memory impairment was prevented by Brazil nuts in young rats (30 days). While the serum selenium concentration was reduced in the oHF group, the serum catalase concentration was reduced in all groups, without changes in lipid peroxidation or protein carbonylation. Brazil nut maternal diet supplementation prevented short- and long-term cognitive impairment in the offspring, which may be related to the selenium levels.
The main goal of the present research is to develop and validate the Perceived Economic Inequality Scale (PEIS), an instrument measuring individuals’ perceptions of economic inequality at the national level. The study was conducted on a representative sample of the Italian population (N = 1,446, 51% women). The factorial structure of the scale was assessed through cross-validated exploratory-confirmatory factor analyses. To inspect the PEIS psychometric properties, item and correlation analyses were performed. The results showed that the PEIS is a valid and reliable unidimensional measure of perceived economic inequality at the national level. Further support of the PEIS construct validity was provided by the correlation of the scale score with the perceived wage gap and ideological beliefs like the economic system justification, social dominance orientation, meritocratic beliefs, and participants’ political orientation. Crucially, multigroup confirmatory factor analysis supported configural, metric, and scalar invariances of the scale across socio-demographic groups. The PEIS allows researchers to assess the subjective component of economic inequality by also serving as a useful tool for unpacking the psychological correlates of perceived inequality.
To evaluate the sensitivity and specificity of the Distress Thermometer (DT) as a screening tool for emotional distress in oncological palliative care patients and to compare the DT with the Edmonton Symptom Assessment System-revised (ESAS-r) and the gold standard to determine the most appropriate assessment method in palliative psychological care.
Methods
Data were collected from psychological screening tests (ESAS-r and DT), and clinical interviews (gold standard) were conducted by a clinical psychologist specialist in palliative oncology from January 2021 to January 2022 in an oncology palliative care service.
Results
The sample consisted of 356 first-time patients with a diagnosis of advanced cancer in palliative care. The most frequently reported oncological diagnoses were gastrointestinal tract (49.3%) and breast (18.3%). Most patients were female (n = 206; 57.9%), 60.4% were married/with a partner, 55.4% had between 6 and 9 years of schooling, and a median age of 57 (range, 46–65) years. The cutoff of the DT was 5, with a sensitivity of 75.88% and specificity of 54.3%. Emotional problems (sadness and nervousness) had a greater area under the curve (AUC) when measured using the DT than the ESAS-r; however, only in the case of the comparative sadness and discouragement was the difference between the AUC marginally significant.
Significance of results
The use of the DT as a screening tool in oncological palliative care is more effective in the evaluation of psychological needs than the ESAS-r. The DT, in addition to evaluation by an expert psychologist, allows for a more comprehensive identification of signs and symptoms to yield an accurate mental health diagnosis based on the International Classification of Diseases-11th Revision and/or Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition.
The objective of this study was to assess the psychosocial distress and associated factors in advanced cancer patients consulting at the outpatient Palliative Care Unit at the National Cancer Institute in Mexico City.
Design
A retrospective study was conducted using electronic records (June 2015 to December 2016).
Sample
A total of 646 patients with advanced cancer during their first visit to the outpatient palliative care unit at the National Cancer Institute in Mexico were evaluated using the Distress Thermometer (DT) and ECOG performance status scores.
Findings
Overall, 62% were women, with a median age of 57 years, and married (54.8%). The most frequent diagnosis was gastrointestinal cancer (28.6%), and 38.9% had a functional performance status of ECOG 2. The median DT score was 4.0 (IQR = 2–6), with 56% reporting DT scores ≥4. The three most frequent problems ≥4 were sadness (82.6%), feeling weak (81.2%), worry (79.6%), and <4 were feeling weak (57.7%), fatigue (55.6%), and financial security (52.1%). The variables associated with distress according to the multiple logistic regression analysis were problems with housing (OR = 2.661, 95% CI = 1.538–4.602), sadness (OR = 2.533, 95% CI = 1.615–3.973), transportation (OR = 1.732, 95% CI = 1.157–2.591), eating (OR = 1.626, 95% CI = 1.093–2.417), nervousness (OR = 1.547, 95% CI = 1.014–2.360), and sleep (OR = 1.469, 95% CI = 1.980–2.203).
Conclusion
The principal factors were related to distress levels, housing problems, transportation issues, and emotional problems such as sadness, nervousness, lower functionality, and younger age. Therefore, psychosocial support is of considerable relevance in palliative care. These findings will help clinicians understand the distress of patients with advanced cancer in palliative care in Latin American countries.
Functional impairment is a defining feature of psychotic disorders. A range of factors has been shown to influence functioning, including negative symptoms, cognitive performance and cognitive reserve (CR). However, it is not clear how these variables may affect functioning in first-episode psychosis (FEP) patients. This 2-year follow-up study aimed to explore the possible mediating effects of CR on the relationship between cognitive performance or specific clinical symptoms and functional outcome.
Methods
A prospective study of non-affective FEP patients was performed (211 at baseline and 139 at follow-up). CR was entered in a path analysis model as potential mediators between cognitive domains or clinical symptoms and functioning.
Results
At baseline, the relationship between clinical variables or cognitive performance and functioning was not mediated by CR. At follow-up, the effect of attention (p = 0.003) and negative symptoms (p = 0.012) assessed at baseline on functioning was partially mediated by CR (p = 0.032 and 0.016), whereas the relationship between verbal memory (p = 0.057) and functioning was mediated by CR (p = 0.014). Verbal memory and positive and total subscales of PANSS assessed at follow-up were partially mediated by CR and the effect of working memory on functioning was totally mediated by CR.
Conclusions
Our results showed the influence of CR in mediating the relationship between cognitive domains or clinical symptoms and functioning in FEP. In particular, CR partially mediated the relationship between some cognitive domains or clinical symptoms and functioning at follow-up. Therefore, CR could improve our understanding of the long-term functioning of patients with a non-affective FEP.
Age-related hearing loss (ARHL) is a sensory impairment, with a dramatic increase in its incidence, which is caused by genetic and environmental factors such as noise and ototoxic drugs. Recent studies correlated ARHL to elevated plasma homocysteine (Hcy) by folate deficiency, suggesting that reduction of Hcy levels by folate supplementation could potentially ameliorate ARHL.
Hyperhomocysteinemia (HHcy), a status that contributes to ARHL, may also arise from malfunction of Hcy remethylation by betaine homocysteine S-methyltransferases (BHMTs) and methionine synthase in the methionine cycle. The expression and/or activity of these enzymes may be altered by ototoxic drugs, including paracetamol (APAP).
Objective
To determine the effect of APAP in cochlear morphology and function of control and Bhmt-/- mice, and to analyze putative preventive effects of folic acid (FA) supplementation.
Materials and Methods
Two-month-old Bhmt-/- mice (n = 47), with greater dependence on folate metabolism for Hcy remethylation, and Bhmt + / + mice (n = 42) were fed control or FA supplemented diets for 30 days. The last day APAP (250 mg/kg) or placebo were injected intraperitoneally.
Hearing was evaluated by recording auditory brainstem responses (ABR) at the beginning of the experiment and after treatments. Picrosirius red staining was used for evaluation of the cochlear lateral wall cytoarchitecture. Plasma and hepatic metabolite levels were determined by HPLC or on Spinlab 100® autoanalyzer.
Results
Loss of Bhmt expression induced HHcy, but an impact on hearing acuity was not observed. Acute APAP administration did not induce ABR threshold shifts. However, following ototoxic treatment, changes of 5–17% in the areas of the stria vascularis and spiral ligament were detected between Bhmt-/- mice under different dietary treatments; cochlear structures of Bhmt-/- mice receiving APAP plus FA supplementation resemble those of the control group. APAP increases susceptibility to ototoxic damage in the presence of HHcy.
Discussion
BHMT plays a central role in cochlear methionine metabolism. FA supplementation modulates Hcy levels, contributing to a proper remethylation status that prevents ARHL.
The functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) is a widely used instrument to assess quality of life (QOL) in hematopoietic stem cell transplant (HSCT) patients, but there is little evidence of its validity in Latin American populations. This study evaluated the psychometric properties of the Spanish language version of the FACT-BMT in Mexican patients.
Method
First, the original version was piloted with 15 HSCT patients to obtain an adequate cultural version, resulting in the adaptation of one item. After that, the new version was completed by 139 HSCT patients.
Results
The results showed a FACT factor structure that explains 70.84% of the total variance, a factor structure similar to the original FACT structure, and with a high internal consistency (Cronbach's alpha = 0.867). For the BMT subscale, the best factor structure included 17 items which explain 61.65% of the total variance with an adequate internal consistency (Cronbach's alpha = 0.696).
Significance of the results
The FACT-BMT was found to be a valid and reliable instrument to evaluate QOL in Mexican patients. Our results constitute new FACT-BMT empirical evidence that supports its clinical and research uses.
Data from the Italian national point-prevalence survey (PPS) of healthcare-associated infections (HAIs) were used to evaluate antimicrobial usage (AMU) in Italy and to identify targets for future interventions.
Methods:
The second Italian PPS was conducted in 2016 as part of the European PPS initiated by the ECDC. We compared these results with those of the first national survey, conducted in 2011.
Results:
An overall AMU prevalence of 44.5% (95% CI, 43.7–45.3) was estimated in 2016. No significant change in AMU prevalence was detected when comparing data with the first survey. In both surveys, the most prevalent indication for AMU was the treatment of infections. Considering all indications, penicillins plus β-lactamase inhibitors (BLIs) were the most commonly prescribed antimicrobial group in 2016; they were used significantly more than in 2011, and piperacillin plus BLI was the most frequently used agent. Broad-spectrum agents accounted for >60% of all antimicrobials for systemic use. No significant increase in the use of carbapenems occurred in 2016. Stable or decreasing carbapenem-resistance levels were identified in this study, although these levels remain alarmingly high for both Klebsiella pneumoniae (50%) and Acinetobacter baumannii (>75%).
Conclusions:
These results can be used to identify priorities and targets for interventions that promote more prudent use of antimicrobials, improve healthcare quality and patient safety, and combat the emergence and spread of antimicrobial-resistant pathogens.
In 1989 an ancient burial consisting of a skeleton and a few objects was discovered at the Monte dei Cappuccini Monastery, in Torino (Italy). Anthropological analysis of the skeleton revealed that it belonged to a young man, and the archaeometric characterization of the objects suggested that most of them are compatible with the Medieval period. As a proper archeological survey was not conducted at the time of the finding, due to the religious nature of the site, a high-precision radiocarbon (14C) dating has been performed. The samples were processed with three different methods: besides the ultrafiltration (UF) treatment, we applied the “collagen” (COL) and the Longin-base (LB) methods. While UF and COL treatments provided compatible results, LB method returned ages older with respect the UF one, with significant disagreements in some cases and this evidence is supported by several measurements on the same individual. Thanks to the reduction of the uncertainty with the high number of measured samples and the availability of historical evidence, the possible age of the burial has been limited to the time interval 1464–1515 cal AD.
Both transposition of the great arteries (TGA) previously submitted to a Senning/Mustard procedure and congenitally corrected TGA (cc-TGA) have the systemic circulation supported by the morphological right ventricle, thereby rendering these patients to heart failure events risk. The aim of this study was to evaluate cardiopulmonary exercise test parameters for stratifying the risk of heart failure events in TGA patients.
Methods:
Retrospective evaluation of adult TGA patients with systemic circulation supported by the morphological right ventricle submitted to cardiopulmonary exercise test in a tertiary centre. Patients were followed up for at least 1 year for the primary endpoint of cardiac death or heart failure hospitalisation. Several cardiopulmonary exercise test parameters were analysed as potential predictors of the combined endpoint and their predictive power were compared (area under the curve).
Results:
Cardiopulmonary exercise test was performed in 44 TGA patients (8 cc-TGA), with a mean age of 35.1 ± 8.4 years. The primary endpoint was reached by 10 (22.7%) patients, with a mean follow-up of 36.7 ± 26.8 months. Heart rate at anaerobic threshold had the highest area under the curve value (0.864), followed by peak oxygen consumption (pVO2) (0.838). Heart rate at anaerobic threshold ≤95 bpm and pVO2 ≤20 ml/kg/min had a sensitivity of 87.5 and 80.0% and a specificity of 82.4 and 76.5%, respectively, for the primary outcome.
Conclusion:
Heart rate at anaerobic threshold ≤95 bpm had the highest predictive power of all cardiopulmonary exercise test parameters analysed for heart failure events in TGA patients with systemic circulation supported by the morphological right ventricle.
It is likely that the Mediterranean diet (MedDiet) may mitigate the adverse effects of obesity on the incidence of type 2 diabetes mellitus (T2DM). We assessed this hypothesis in a cohort of 18 225 participants initially free of diabetes (mean age: 38 years, 61 % women). A validated semi-quantitative 136-item FFQ was used to assess dietary intake and to build a 0–9 score of adherence to MedDiet. After a median of 9·5-year follow-up, 136 incident cases of T2DM were confirmed during 173 591 person-years follow-up. When MedDiet adherence was low (≤4 points), the multivariable-adjusted hazard ratios (HR) were 4·07 (95 % CI 1·58, 10·50) for participants with BMI 25–29·99 kg/m2 and 17·70 (95 % CI 6·29, 49·78) kg/m2 for participants with BMI≥30 kg/m2, (v.<25 kg/m2). In the group with better adherence to the MedDiet (>4 points), these multivariable-adjusted HR were 3·13 (95 % CI 1·63, 6·01) and 10·70 (95 % CI 4·98, 22·99) for BMI 25–30 and ≥30 kg/m2, respectively. The P value for the interaction was statistically significant (P=0·002). When we assessed both variables (BMI and MedDiet) as continuous, the P value for their interaction product-term was marginally significant (P=0·051) in fully adjusted models. This effect modification was not explained by weight changes during follow-up. Our results suggest that the MedDiet may attenuate the adverse effects of obesity on the risk of T2DM.
Bicuspid aortic valve is the most common CHD. Its association with early valvular dysfunction, endocarditis, thoracic aorta dilatation, and aortic dissection is well established.
Objective
The aim of this study was to assess the incidence and predictors of cardiac events in adults with bicuspid aortic valve.
Methods
We carried out a retrospective analysis of cardiac outcomes in ambulatory adults with bicuspid aortic valve followed-up in a tertiary hospital centre. Outcomes were defined as follows: interventional – intervention on the aortic valve or thoracic aorta; medical – death, aortic dissection, aortic valve endocarditis, congestive heart failure, arrhythmias, or ischaemic heart disease requiring hospital admission; and a composite end point of both. Kaplan–Meier curves were generated to determine event rates, and predictors of cardiac events were determined by multivariate analysis.
Results
A total of 227 patients were followed-up over 13±9 years; 29% of patients developed severe aortic valve dysfunction and 12.3% reached ascending thoracic aorta dimensions above 45 mm. At least one cardiac outcome occurred in 38.8% of patients, with an incidence rate at 20 years of follow-up of 47±4%; 33% of patients were submitted to an aortic valve or thoracic aorta intervention. Survival 20 years after diagnosis was 94±2%. Independent predictors of the composite end point were baseline moderate–severe aortic valve dysfunction (hazard ratio, 3.19; 95% confidence interval, 1.35–7.54; p<0.01) and aortic valve leaflets calcification (hazard ratio, 4.72; 95% confidence interval, 1.91–11.64; p<0.005).
Conclusions
In this study of bicuspid aortic valve, the long-term survival was excellent but with occurrence of frequent cardiovascular events. Baseline aortic valve calcification and dysfunction were the only independent predictors of events.
One of the most severe extinction events in Earth history, the Triassic–Jurassic extinction, struck against a backdrop of radical increases in atmospheric CO2 and supercontinent breakup. This juxtaposition of first-order geophysical and biotic changes produced excellent case studies in Earth-Life Transitions. Recent recognition of a worldwide “carbonate gap” following the extinction has focused attention on causes, often invoked as eustacy or ocean acidification, but the ecology of the extinction aftermath remains poorly understood. Results from paleoecological studies on three separate Triassic–Jurassic records are presented and incorporated into regional depositional models. Examination of the Penarth Group of Great Britain reveals a widespread, laterally homogenous, level-bottom microbial stromatolite regime across the innermost ramp. The Sunrise Formation in Nevada, USA, was deposited during a biosiliceous (“glass”) regime dominated by demosponges across the inner ramp that lasted at least two million years. Investigations of the Pucará group in the central Andes of Peru revealed a demosponge-dominated level-bottom glass ramp with many similarities to the Nevada deposits, but offering broader regional extent and variation in recorded depositional settings. This suite of studies demonstrates state-shifts in marine ecological systems that also profoundly altered regional sedimentation regimes. The sponge-dominated systems produced glass ramp conditions instead of carbonate ramps, and indicate the importance of marine silica concentrations. The post-extinction changes in regional marine ecology demonstrate connectivity to changes in global climate and terrigenous weathering driven by global-scale geophysical processes.
We aimed to determine whether the results of surveillance cultures were associated with use of appropriate empirical antibiotic therapy among patients with carbapenem-resistant Acinetobacter baumannii infections. We found that surveillance status was not associated with appropriate empirical antibiotic therapy (P=.36). There were significant delays to concordant therapy among surveillance-positive patients (P=.03).

C46 was a Commission of the Executive Committee of the IAU under Division XII (Union-Wide Activities), then after 2012 under Division C (Education, Outreach, and Heritage). It was the only commission dealing exclusively with astronomy education; a previous Commission 38 (Exchange of Astronomers), which allocated travel grants to astronomers who needed them, and a Working Group on the Worldwide Development of Astronomy, have been absorbed by Commission 46.
