Adaptation Narratives: Climate Change and Environmental Politics in Mexican Costal Communities
This dissertation explores some key challenges the Mexican government and international organizations such as the World Bank may face when implementing climate change adaptation initiatives in coastal lagoon communities in the Mexican state of Tabasco, in the Gulf of Mexico. My analysis of the government’s climate change adaptation initiatives, scientists’ explanations, and fishers’ views on local environmental changes is based on political ecology approaches to environmental narratives, and critical literature on climate change. It outlines the interaction among three environmental narratives: that produced by the Mexican government and its allies who are re-orienting environmental programs into climate change adaptation programs; scientific narratives on coastal environmental processes including coastal erosion; and the narrative produced by poor fishers who are dependent on lagoon and coastal resources for their livelihoods, and who blame the off shore oil industry for most of their environmental problems. Scientific accounts of coastal environmental change tend to support more the position of fishers than the government, which produces a need for the government to be selective in how it uses science to justify its adaptation programs. The dissertation then examines the challenges that state initiatives of this type face when they interact with local environmental politics involving fishers and the state-owned oil industry. While fishers blame the oil industry for environmental problems, government adaptation programs seek to enrol fishers and the oil industry together as vulnerable to the local effects of climate change such as coastal erosion and increased frequency of hurricanes. I discuss how through processes of simplification, state agencies render complex political issues into technical problems, but how, in light of local conflicts, climate change adaptation interventions become highly political on the ground. I also argue that climate change policy analysis must be done in light of past and failed state interventions in Tabasco, which have resulted in what scholars have called a “harmful development” for fishers and ecosystems (Tudela, 1989)

The IL7RA rs6897932 polymorphism is associated with progression of liver fibrosis in patients with chronic hepatitis C: Repeated measurements design
The polymorphisms at the α-chain of the IL-7 receptor (IL7RA) have been related to T-cell homeostasis and development and may contribute to immune system deregulation. In the present study, we analyzed the association between IL7RA polymorphisms and the progression of liver fibrosis in patients infected with HCV. We carried out a retrospective study with a design consisting of repeated measurements in 187 HCV-infected patients, to study the risk prediction of liver fibrosis progression using genetic factors. We genotyped the rs6897932, rs987106 and rs3194051 IL7RA polymorphisms using the Agena Bioscience's MassARRAY. Transient elastography was used to measure liver stiffness. The used cut-offs were: 0.05). In univariate analysis, the rs6897932 T allele had a positive relationship with an increase in LSM (arithmetic mean ratio (AMR) = 1.21 (95%CI = 1.08; 1.36); p = 0.001), progression to advanced fibrosis (F≥3) (odds ratio (OR) = 2.51 (95%CI = 1.29; 4.88); p = 0.006) and progression to cirrhosis (F4) (OR = 2.71 (95%CI = 0.94; 5.03); p = 0.069). In multivariable analysis, the rs6897932 T allele was related to a higher increase of LSM values during follow-up (adjusted AMR = 1.27 (95%CI = 1.13; 1.42); p<0.001) and higher odds of progression to advanced fibrosis [adjusted OR = 4.46 (95%CI = 1.87; 10.62); p = 0.001], and progression to cirrhosis [adjusted OR = 3.92 (95%CI = 1.30; 11.77); p = 0.015]. Regarding IL7RA rs987106 and rs3194051 polymorphisms, we did not find significant results except for the relationship between IL7RA rs987106 and the increase in LSM values [adjusted OR = 1.12 (95%CI = 1.02; 1.23); p = 0.015]. The IL7RA rs6897932 polymorphism seems to be related to increased risk of liver fibrosis progression in HCV-infected patients. Thus, the rs6897932 polymorphism could be related to the physiopathology of CHC and might be used to successfully stratify the risk of CHC progression.This work has been supported by grants given by Fondo de Investigación de Sanidad en España (FIS) [Spanish Health Founds for Research] [grant numbers PI14CIII/00011, PI15CIII/00024 and PT13/0001].

Genomic characterisation of respiratory syncytial virus: a novel system for whole genome sequencing and full-length G and F gene sequences
To advance our understanding of respiratory syncytial virus (RSV) impact through genomic surveillance, we describe two PCR-based sequencing systems, (i) RSVAB-WGS for generic whole-genome sequencing and (ii) RSVAB-GF, which targets major viral antigens, G and F, and is used as a complement for challenging cases with low viral load. These methods monitor RSV genetic diversity to inform molecular epidemiology, vaccine effectiveness and treatment strategies, contributing also to the standardisation of surveillance in a new era of vaccines.This research was partially funded by Instituto de Salud Carlos III through the Project PI18/00167, PI21CIII/00019 (MPY 439-21) and PI21/00377, and partially by UNESPA donation- “COVIDSEQUNESPA” (grant number MPY 226/22).

Estado de México y democracia en los albores del siglo XXI
De acuerdo con su título, este libro, compuesto por seis capítulos y dos anexos, reúne textos relativos a la democracia y al Estado de México, una de las principales entidades federativas de la República Mexicana. La importancia del Estado de México en el contexto nacional es indiscutible: de las 32 entidades que integran el país, es la que tiene más habitantes y electores (el segundo y el tercer lugares en ambos sentidos son ocupados, respectivamente, por el Distrito Federal y Veracruz), en tanto que está en el segundo lugar por el tamaño de su economía (en el primero se ubica el Distrito Federal y en el tercero, Nuevo León)
Individual or Group-based Approach to the Assessment of Preschool Children: A Comparison using the INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA)
Introduction: It is unclear if the assessment of early child development can be carried out using a group approach, as opposed to individually.
 Objective: To compare scores obtained from children aged 22 to 26 months assessed either in small groups or individually using the INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA), which measures cognition, language, motor skills, behavior, attention and socio-emotional reactivity.
 Methods: A small group based strategy for administering and scoring the INTER-NDA was developed. Thirty-six preschool children attending four Centros de Cuidado y Atención Infantil of the Sistema Nacional para el Desarrollo Integral de la Familia (DIF) of Mexico were assessed in small groups of three children by a teacher specifically trained in the INTER-NDA. A second teacher, unaware of the group results, assessed the children individually on a different day. The sex, age, weight, length and head circumference of the children at the time of assessment were recorded.
 Results: INTER-NDA domain scores for group and individual assessments were statistically significantly correlated (range r=0.35 to r=1.00) for all domains except receptive language (r=0.25, p=0.14). Bland-Altman analysis showed agreement between group and individual scores for the language, behavior, attention and socio-emotional reactivity domains, and consistency (but not agreement) between group and individual scores for the cognitive and motor domains. None of the differences between group and individual scores examined were statistically significant, even after adjusting for the children’s age, sex, nutritional status and location of the preschool.
 
 Conclusion: INTER-NDA domain specific scores obtained following group and individual assessment of children aged 22 to 26 months are consistent. It is feasible for trained preschool teachers to administer INTER-NDA at both group and individual level.</jats:p
The calcium-sensing receptor increases activity of the renal NCC through the WNK4-SPAK pathway
Background Hypercalciuria can result from activation of the basolateral calcium-sensing receptor (CaSR), which in the thick ascending limb of Henle’s loop controls Ca2+ excretion and NaCl reabsorption in response to extracellular Ca2+. However, the function of CaSR in the regulation of NaCl reabsorption in the distal convoluted tubule (DCT) is unknown. We hypothesized that CaSR in this location is involved in activating the thiazide-sensitive NaCl cotransporter (NCC) to prevent NaCl loss. Methods We used a combination of in vitro and in vivo models to examine the effects of CaSR on NCC activity. Because the KLHL3-WNK4-SPAK pathway is involved in regulating NaCl reabsorption in the DCT, we assessed the involvement of this pathway as well. Results Thiazide-sensitive 22Na+ uptake assays in Xenopus laevis oocytes revealed that NCC activity increased in a WNK4-dependent manner upon activation of CaSR with Gd3+. In HEK293 cells, treatment with the calcimimetic R-568 stimulated SPAK phosphorylation only in the presence of WNK4. The WNK4 inhibitor WNK463 also prevented this effect. Furthermore, CaSR activation in HEK293 cells led to phosphorylation of KLHL3 and WNK4 and increased WNK4 abundance and activity. Finally, acute oral administration of R-568 in mice led to the phosphorylation of NCC. Conclusions Activation of CaSR can increase NCC activity via the WNK4-SPAK pathway. It is possible that activation of CaSR by Ca2+ in the apical membrane of the DCT increases NaCl reabsorption by NCC, with the consequent, well known decrease of Ca2+ reabsorption, further promoting hypercalciuria
Hypothalamic AMPK-ER Stress-JNK1 Axis Mediates the Central Actions of Thyroid Hormones on Energy Balance
Thyroid hormones (THs) act in the brain to modulate energy balance. We show that central triiodothyronine (T3) regulates de novo lipogenesis in liver and lipid oxidation in brown adipose tissue (BAT) through the parasympathetic (PSNS) and sympathetic nervous system (SNS), respectively. Central T3 promotes hepatic lipogenesis with parallel stimulation of the thermogenic program in BAT. The action of T3 depends on AMP-activated protein kinase (AMPK)-induced regulation of two signaling pathways in the ventromedial nucleus of the hypothalamus (VMH): decreased ceramide-induced endoplasmic reticulum(ER) stress, which promotes BAT thermogenesis, and increased c-Jun N-terminal kinase (JNK) activation, which controls hepatic lipid metabolism. Of note, ablation of AMPK alpha 1 in steroidogenic factor 1 (SF1) neurons of the VMH fully recapitulated the effect of central T3, pointing to this population in mediating the effect of central THs on metabolism. Overall, these findings uncover the underlying pathways through which central T3 modulates peripheral metabolism.Peer reviewe

Acupuncture and rehabilitation of the painful shoulder: study protocol of an ongoing multicentre randomised controlled clinical trial [ISRCTN28687220]
BACKGROUND: Although the painful shoulder is one of the most common dysfunctions of the locomotor apparatus, and is frequently treated both at primary healthcare centres and by specialists, little evidence has been reported to support or refute the effectiveness of the treatments most commonly applied. According to the bibliography reviewed, physiotherapy, which is the most common action taken to alleviate this problem, has not yet been proven to be effective, because of the small size of sample groups and the lack of methodological rigor in the papers published on the subject. No reviews have been made to assess the effectiveness of acupuncture in treating this complaint, but in recent years controlled randomised studies have been made and these demonstrate an increasing use of acupuncture to treat pathologies of the soft tissues of the shoulder. In this study, we seek to evaluate the effectiveness of physiotherapy applied jointly with acupuncture, compared with physiotherapy applied with a TENS-placebo, in the treatment of painful shoulder caused by subacromial syndrome (rotator cuff tendinitis and subacromial bursitis). METHODS/DESIGN: Randomised controlled multicentre study with blind evaluation by an independent observer and blind, independent analysis. A study will be made of 465 patients referred to the rehabilitation services at participating healthcare centres, belonging to the regional public health systems of Andalusia and Murcia, these patients presenting symptoms of painful shoulder and a diagnosis of subacromial syndrome (rotator cuff tendinitis and subacromial bursitis). The patients will be randomised into two groups: 1) experimental (acupuncture + physiotherapy); 2) control (TENS-placebo + physiotherapy); the administration of rescue medication will also be allowed. The treatment period will have a duration of three weeks. The main result variable will be the change produced on Constant's Shoulder Function Assessment (SFA) Scale; as secondary variables, we will record the changes in diurnal pain intensity on a visual analogue scale (VAS), nocturnal pain intensity on the VAS, doses of non-steroid anti-inflammatory drugs (NSAIDs) taken during the study period, credibility scale for the treatment, degree of improvement perceived by the patient and degree of improvement perceived by the evaluator. A follow up examination will be made at 3, 6 and 12 months after the study period has ended. Two types of population will be considered for analysis: per protocol and per intention to treat. DISCUSSION: The discussion will take into account the limitations of the study, together with considerations such as the choice of a simple, safe method to treat this shoulder complaint, the choice of the control group, and the blinding of the patients, evaluators and those responsible for carrying out the final analysis
