The environmental protection of tropical marine and coastal areas faces different challenges due to the diversity of aspects related to these areas, which include natural, social and economical issues. Despite these challenges, efforts for the protection of these areas are urgent nowadays because of the dramatical increase of human related threats like habitat destruction and population growth. Malaga Bay (MB) is a tectonic estuarine system located in Panama Bight (central region of the Colombian Pacific coast), which due to its origin shows important environmental characteristics of few sites in the Tropical Eastern Pacific (TEP) match. For these reasons, the government of Colombia declared in 2010, the bay’s marine area as a Marine National Natural Park in order to preserve its unique estuarine marine biodiversity. Despite this measure, MB presents several conditions that make environmental protection a very difficult task. In this paper, we present the geographical context, biodiversity and natural resources, environmental threats, the complexity of economic and social context, and the institutional and legal context of MB, to exemplify the difficulty that the protection of marine areas face in the TEP.

Pancreatic neuroendocrine tumors:Are tumors smaller than 2 cm truly indolent?

BACKGROUND Pancreatic neuroendocrine tumors(PNETs)are relatively rare but rank as the second most common pancreatic neoplasm.They can be functional,causing early metabolic disturbances due to hormone secretion,or non-functional and diagnosed later based on tumor size-related symptoms.Recent diagnoses of PNETs under 2 cm in size have sparked debates about their management;some practitioners advocate for surgical removal and others suggest observation due to the tumors’lower potential for malignancy.However,it is unclear whether managing these small tumors expectantly is truly safe.AIM To evaluate poor prognostic factors in PNETs based on tumor size(>2 cm or<2 cm)in surgically treated patients.METHODS This cohort study included 64 patients with PNETs who underwent surgical resection between 2006 and 2019 at a high-complexity reference hospital in Medellín,Colombia.To assess patient survival,quarterly follow-ups were conducted during the first year after surgery,followed by semi-annual con-sultations at the hospital's hepatobiliary surgery department.Qualitative variables were described using absolute and relative frequencies,and quantitative variables were expressed using measures of central tendency and their corresponding measures of dispersion.RESULTS The presence of lymph node involvement,neural involvement,and lymphovascular invasion were all associated with an increased risk of mortality,with hazard ratios of 5.68(95%CI:1.26–25.61,P=0.024),6.44(95%CI:1.43–28.93,P=0.015),and 24.87(95%CI:2.98–207.19,P=0.003),respectively.Neural involvement and lymphovascular invasion were present in tumors smaller than 2 cm in diameter and those larger than 2 cm in diameter.The recurrence rates between the two tumor groups were furthermore similar:18.2%for tumors smaller than 2 cm and 21.4%for tumors larger than 2 cm.Patient survival was additionally comparable between the two tumor groups.CONCLUSION Tumor size does not dictate prognosis;lymph node and lymphovascular involvement affect mortality,which high-lights that histopath

BACKGROUND Suicide is a leading cause of preventable death worldwide,with its peak of maximum incidence in later life.Depression often puts an individual at higher risk for suicidal behaviour.In turn,depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing.AIM To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults,and to examine the effects of depression treatment to tackle suicide behaviour in this population.METHODS A systematic review of empirical studies,published from 2000 onwards,was conducted.Suicidal behaviour was addressed considering its varying forms(i.e.,wish to die,ideation,attempt,and completed suicide).RESULTS Thirty-five papers were selected for review,comprising both clinical and epidemiological studies.Most of studies focused on suicidal ideation(60%).The studies consistently pointed out that the risk was related to depressive episode severity,psychiatric comorbidity(anxiety or substance use disorders),poorer health status,and loss of functionality.Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults.Finally,the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response.Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms.CONCLUSION To sum up,common and age-specific risk factors seem to be involved in suicide development in depressive older adults.A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

项目背景Casa 7A是坐落于哥伦比亚Villeta镇的一座乡村别墅,它距离波哥大西部仅1.5小时车程,海拔高度达967米,这里的气候一年四季都是干燥炎热的。地理环境非常明确——一片从山顶延伸到溪流底的陡峭土地。客户要求在550平方米的建筑面积内设计3间客房、一间工作室、一个社会活动平台、一个阳台和一个游泳池,所有这些设计还必须满足一个要求,即在别墅没有客人入住时,房子能够关闭。
