The thallium-barium double nitrite, TlBa(NO)5, is pyroelectric in the 77-600 K range and crystallizes in the Pca2 space group. The lattice constants at 293 K are: a = 17.868(12), b = 4.934(3), c = 13-426(11) A (MoKa, λ = 0.71069 A). There are four stoichiometric units in the unit cell of volume V= 1184(1) A ( D = 3.98, D = 3.979 Mgm), F (000) = 1232, μ = 20.36mm. The crystal structure was solved by Patterson and Fourier methods and refined by least-squares to a final conventional agreement index R = 0.053 for 1371 independent reflections collected in a θ range of 3-30°, using MoKα radiation. There are two independent barium atoms surrounded by NO groups, both with coordination number 10 and distances in the ranges Ba-O = 2.69(4)-3.18(4) A and Ba-N = 3.01(4)-3.18(4) A. The environment of thallium is clearly affected by the lone-pair stereoactivity and involves 12 Tl-O and Tl-N contacts less than 3.5A, but only four Tl-O distances are shorter than 3 A (min. 2.76(2), max. 2.85(3) A), with a pyramidal coordination and thallium at the apex of the pyramid. All these coordination polyhedra are joined in chains running along the shortest lattice vector [010]. The single crystal electronic spectra, studied in absorption with polarized light and in photostimulated emission, are interpreted as due to transitions involving NO electronic levels perturbed by Tl, whose spin-orbit interaction makes probable also the forbidden singlet-triplet transitions, in agreement with the interpretative picture given for post-transition metal nitrites.

Climate change poses significant risks to health and health systems, with the greatest impacts in low- and middle-income countries - which are least responsible for greenhouse gas emissions. The Conference of Parties 28 at the 2023 United Nations Climate Change Conference led to agreement on the need for holistic and equitable financing approaches to address the climate and health crisis. This paper provides an overview of existing climate finance mechanisms - that is, multilateral funds, voluntary market-based mechanisms, taxes, microlevies and adaptive social protection. We discuss these approaches' potential use to promote health, generate additional health sector resources and enhance health system sustainability and resilience, and also explore implementation challenges. We suggest that public health practitioners, policy-makers and researchers seize the opportunity to leverage climate funding for better health and sustainable, climate-resilient health systems. Emphasizing the wider benefits of investing in health for the economy can help prioritize health within climate finance initiatives. Meaningful progress will require the global community acknowledging the underlying political economy challenges that have so far limited the potential of climate finance to address health goals. To address these challenges, we need to restructure financing institutions to empower communities at the frontline of the climate and health crisis and ensure their needs are met. Efforts from global and national level stakeholders should focus on mobilizing a wide range of funding sources, prioritizing co-design and accessibility of financing arrangements. These stakeholders should also invest in rigorous monitoring and evaluation of initiatives to ensure relevant health and well-being outcomes are addressed., ((c) 2024 The authors; licensee World Health Organization.)

Women, children and adolescents (WCA), especially in low-income and middle-income countries (LMICs), will bear the worst consequences of climate change during their lifetimes, despite contributing the least to global greenhouse gas emissions. Investing in WCA can address these inequities in climate risk, as well as generating large health, economic, social and environmental gains. However, women's, children's and adolescents' health (WCAH) is currently not mainstreamed in climate policies and financing. There is also a need to consider new and innovative financing arrangements that support WCAH alongside climate goals.We provide an overview of the threats climate change represents for WCA, including the most vulnerable communities, and where health and climate investments should focus. We draw on evidence to explore the opportunities and challenges for health financing, climate finance and co-financing schemes to enhance equity and protect WCAH while supporting climate goals.WCA face threats from the rising burden of ill-health and healthcare demand, coupled with constraints to healthcare provision, impacting access to essential WCAH services and rising out-of-pocket payments for healthcare. Climate change also impacts on the economic context and livelihoods of WCA, increasing the risk of displacement and migration. These impacts require additional resources to support WCAH service delivery, to ensure continuity of care and protect households from the costs of care and enhance resilience. We identify a range of financing solutions, including leveraging climate finance for WCAH, adaptive social protection for health and adaptations to purchasing to promote climate action and support WCAH care needs., Competing Interests: Competing interests: None declared., (© World Health Organization 2024.

Background: Parathyroid cancer (PC) is a rare sporadic or hereditary malignancy whose histologic features were redefined with the 2022 WHO classification. A total of 24 Italian institutions designed this multicenter study to specify PC incidence, describe its clinical, functional, and imaging characteristics and improve its differentiation from the atypical parathyroid tumour (APT)., Methods: All relevant information was collected about PC and APT patients treated between 2009 and 2021., Results: Among 8361 parathyroidectomies, 351 patients (mean age 59.0 ± 14.5; F = 210, 59.8%) were divided into the APT (n = 226, 2.8%) and PC group (n = 125, 1.5%). PC showed significantly higher rates ( p < 0.05) of bone involvement, abdominal, and neurological symptoms than APT (48.8% vs. 35.0%, 17.6% vs. 7.1%, 13.6% vs. 5.3%, respectively). Ultrasound (US) diameter >3 cm (30.9% vs. 19.3%, p = 0.049) was significantly more common in the PC. A significantly higher frequency of local recurrences was observed in the PC (8.0% vs. 2.7%, p = 0.022). Mortality due to consequences of cancer or uncontrolled hyperparathyroidism was 3.3%., Conclusions: Symptomatic hyperparathyroidism, high PTH and albumin-corrected serum calcium values, and a US diameter >3 cm may be considered features differentiating PC from APT. 2022 WHO criteria did not impact the diagnosis.

Climate change is a multidimensional issue that affects all aspects of society, including public health and human rights. Climate change is already severely impacting people's health and threatening people's guaranteed fundamental rights, including those to life, health, self-determination, and education, among others. Across geographical regions, population groups and communities who are already marginalized due to age, gender, ethnicity, income, and other socioeconomic factors, are those who are disproportionately affected by climate impacts despite having contributed the least to global emissions. Although scholars have been calling for a human rights-based approach and a health perspective to climate action, the literature looking at this multidisciplinary intersection is still nascent, and governments have yet to implement such intersectoral policies. This commentary begins to reflect on the relationship between climate change, human rights, and public health from the perspective of young people engaged in climate action and discourse at the national and international levels. It presents a way forward on what we, as youth climate advocates and researchers, believe is a priority to bring intersectoral integration of human rights and public health approaches to climate change to fruition. First, scholars and practitioners should examine and support youth-led climate interventions that tackle human rights and public health violations incurred by the climate crisis. Second, participatory approaches to climate change must be designed by working synergistically with climate-vulnerable groups, including children and young people, practitioners and scholars in public health and human rights sectors to holistically address the social, health, and environmental impacts of the climate crisis and root causes of injustice. Finally, we recommend more holistic data collection to better inform evidence-based climate policies that operationalize human rights and public health co-benefits.

Climate change is the greatest challenge of our century. Children, adolescents, and youth will bear the most severe impacts, physically, socially, economically, and psychologically. In response to this immense threat and to the failure of international climate negotiations to date, young people are taking to the streets and using global fora to call for climate justice. While these protests have received much attention, there has been limited examination of these and other youth-led efforts through the lens of a human rights-based approach and its operational principles: participation, equality and nondiscrimination, accountability, and transparency. This paper draws from academic and gray literature, as well as the authors' experience as practitioners and young activists, to argue that young people, by promoting human rights-based operational principles at the international, national, and local levels, are pioneering a human rights-based approach to climate change. The paper concludes by suggesting how policy makers can support and empower young people to advance an explicit human rights-based agenda, while concurrently translating human rights-based operational principles into climate change policies and practice., Competing Interests: Competing interests: None declared., (Copyright © 2021 Gasparri, El Omrani, Hinton, Imbago, Lakhani, Mohan, Yeung, and Bustreo.)

Inactivating mutations of the CDC73 tumor suppressor gene have been reported in parathyroid carcinomas (PC), in association with the loss of nuclear expression of the encoded protein, parafibromin. The aim of this study was to further investigate the role of the CDC73 gene in PC and evaluate whether gene carrier status and/or the loss of parafibromin staining might have an effect on the outcome of the disease. We performed genetic and immunohistochemical studies in parathyroid tumor samples from 35 patients with sporadic PC. Nonsense or frameshift CDC73 mutations were detected in 13 samples suitable for DNA sequencing. Six of these mutations were germline. Loss of parafibromin expression was found in 17 samples. The presence of the CDC73 mutation as well as the loss of parafibromin predicted a high likelihood of subsequent recurrence and/or metastasis (92.3%, P=0.049 and 94.1%, P=0.0017 respectively), but only the latter was associated with a decreased overall 5- and 10-year survival rates (59%, P=0.107, and 23%, P=0.0026 respectively). The presence of both the CDC73 mutation and loss of parafibromin staining compared with their absence predicted a lower overall survival at 10- (18 vs 84%, P=0.016) but not at 5-year follow-up. In conclusion, loss of parafibromin staining, better than CDC73 mutation, predicts the clinical outcome and mortality rate. The added value of CDC73 mutational analysis is the possibility of identifying germline mutations, which will prompt the screening of other family members.

Objectives: Acute hypercalcemia is a serious condition and represents a physician-surgical emergency: the difficulty in setting a precise diagnosis is due to several possibilities that can cause the condition. It is our purpose to critically evaluate the most actual schemes of treatment and the conditions that could favour the appearance of a hypercalcemic acute crisis., Materials and Methods: A retrospective study was performed considering 1321 patients (638 primary HPT, 683 secondary or tertiary HPT) operated from 1975 to December 2002 for Primary, Secondary and Tertiary HPT., Results: It should be noticed that out of 638 cases of Primary HPT this syndrome was present in 35 patients (Ca higher than 15 mg/dl): if you compare these cases with the hyperparathyroid population with calcium less than 15 mg/dl it is possible to observe that a double adenoma or a carcinoma were more frequently found in acute HPT, as the cystic appearance of the lesion. The weight of the adenoma and the PTH assay are strictly correlated with the appearance of this syndrome. The mortality rate is also higher (2.8% to 0.1%) than in the hyperparathyroid patient who underwent parathyroidectomy without hypercalcemic crisis., Conclusion: These characteristics suggest that an early operation is mandatory in the patients in whom such a possibility could be expected, before serious involvement of the cardiovascular, renal or neuromuscular system. We can point out the rarity of this syndrome in Secondary and Tertiary HPT: just one case in Secondary out of 683 patients operated on from 1975 until December 2002.

Aims: To determine whether, in secondary and tertiary hyperparathyroidism (HPT), quick parathyroid hormone (PTH) assay can be used to prevent persistent or recurrent HPT. Another point was to determine, considering the PTH decrease, the cut-off point at which the operation could be considered well performed., Methods: A retrospective study was performed evaluating all cases operated on since 1975 until 2002, 679 patients, and particularly the analysis of two groups of patients that underwent surgical treatment for secondary and tertiary HPT in the period 1995-2002. In the first group, (January 1995-October 1999) 207 (167 HPT II and 40 HPT III) neck explorations were performed without the aid of quick PTH assay; in the second group (November 1999-December 2002), 192 (153 HPT II and 39 HPT III) patients were operated on with blood samples for quick PTH., Results: In the first group the percentage of success for secondary HPT was 93.8 versus 96.2 of the second group and 91.7 versus 94.2 for tertiary HPT. In reoperations the percentage of success was 72.7 in the first group and 87.5 in the second one., Conclusions: There are no substantial differences in persistences or recurrences between subtotal or total parathyroidectomy (PTx) with autotransplantation (AT). The choice of the gland to be left in the neck or transplanted in the forearm and the modalities of doing so are very important, considering the macroscopical and histological aspects. Intraoperative PTH monitoring is a useful aid during the first cervical exploration for secondary and tertiary HPT to prevent the development of persistent or recurrent HPT. The cut-off point for secondary HPT is 70% (in difficult cases with more than 2 assays, 75%) and for tertiary HPT 50% and 70% respectively.

Objective: To determine, in a series of patients with secondary and tertiary parathyroid hyperplasia, whether the type of parathyroidectomy (subtotal, total with autotransplantation, or total), the histologic pattern of the parathyroid tissue, or the proliferative index, as determined by Ki-67 analysis, could predispose patients to recurrent hyperparathyroidism., Summary Background Data: Recurrent hyperparathyroidism appears in 10--70% of the patients undergoing surgery for secondary or tertiary hyperparathyroidism. The incidence could be related to the type of operation (Rothmund) but also depends on the histologic pattern of the glands removed (Niederle)., Methods: The retrospective investigation was performed on 446 patients undergoing parathyroid surgery. They were also studied in relation to the possibility of renal transplantation. In this population, two homogeneous groups were subsequently identified (23 patients with clear signs of recurrence and 27 patients apparently cured); they were studied from the histologic and immunohistochemical point of view using antibody to Ki-67 antigen., Results: Subtotal parathyroidectomy, total parathyroidectomy with autotransplantation, and total parathyroidectomy produced similar results when considering the regression of osteodystrophy, pruritus, and ectopic calcification. As one could anticipate, total parathyroidectomy increased the incidence of hypoparathyroidism. The percentage of recurrence was 5% to 8% after subtotal parathyroidectomy, total parathyroidectomy with autotransplantation, and total parathyroidectomy, and only after incomplete parathyroidectomy did this percentage climb to 34.7%. In the recurrence group, the nodular form was more common and the proliferative fraction detected by Ki-67 was 1.9%; it was 0.81% in the control group., Conclusions: Because more radical procedures were not more effective, the authors favor a less radical procedure such as subtotal parathyroidectomy. Histologic patterns and proliferative fraction could be useful indices of a recurrence, and these patients should be watched closely after surgery.
