Gray platelet syndrome: Management of perioperative bleeding in redo cardiac surgery

Gray platelet syndrome (GPS) is a rare (<1/1 000 000) and inherited platelet function disorder characterized by macrothrombocytopenia, α-granule deficiency, and hemorrhages. Bleeding intensity does not correlate with platelet count nor with functional test results. We hereby describe the perioperative bleeding prevention and management of a patient with GPS requiring multiple redo cardiac surgeries.     

South African abortion attitudes from 2007-2016: the roles of religiosity and attitudes toward sexuality and gender equality

ABSTRACT

Abortion is legal in South Africa, but negative abortion attitudes remain common and are poorly understood. We used nationally representative South African Social Attitudes Survey data to analyze abortion attitudes in the case of fetal anomaly and in the case of poverty from 2007 to 2016 (n = 20,711; ages = 16+). We measured correlations between abortion attitudes and these important predictors: religiosity, attitudes about premarital sex, attitudes about preferential hiring and promotion of women, and attitudes toward family gender roles. Abortion acceptability for poverty increased over time (b = 0.05, p < .001), but not for fetal anomaly (b = ?0.008, p = .284). Highly religious South Africans reported lower abortion acceptability in both cases (Odds Ratio (OR)_anomaly = 0.85, p = .015; OR_poverty = 0.84, p = .02). Premarital sex acceptability strongly and positively predicted abortion acceptability (OR_anomaly = 2.63, p < .001; OR_poverty = 2.46, p < .001). Attitudes about preferential hiring and promotion of women were not associated with abortion attitudes, but favorable attitudes about working mothers were positively associated with abortion acceptability for fetal anomaly ((OR_anomaly = 1.09, p = .01; OR_poverty = 1.02, p = .641)). Results suggest negative abortion attitudes remain common in South Africa and are closely tied to religiosity, traditional ideologies about sexuality, and gender role expectations about motherhood.     

“龙虎交战”针法针刺八脉交会穴对偏头痛患者头痛天数及血清CGRP表达的影响＊

目的 观察“龙虎交战”针法针刺八脉交会穴对无先兆偏头痛（Migraine without aura，MO）患者头痛天数及外周血降钙素基因相关肽（Calcitonin gene related peptide，CGRP）表达水平的影响。方法 按照头痛程度将90例MO受试者区层随机分为治疗Ⅰ组、治疗Ⅱ组和对照组各30例。治疗Ⅰ组施以“龙虎交战”针法针刺八脉交会穴（外关和足临泣），治疗Ⅱ组施以平补平泻针法针刺八脉交会穴（外关和足临泣），对照组施以平补平泻针法针刺非经非穴点，每次留针30分钟，5次/周，共治疗20次。于治疗前、治疗结束4周后的随访分别记录三组患者头痛天数的变化情况以判定疗效，并采集患者治疗前、治疗结束4周后随访的肘部静脉血用ELISA法检测血清中的CGRP含量的变化。结果 ①各组治疗前患者的头痛天数无显著差异（Ｐ > 0.05），治疗Ⅰ组、治疗Ⅱ组和对照组治疗结束4周后随访的头痛天数较治疗前均显著降低（Ｐ < 0.05）；治疗Ⅰ组头痛天数的降低显著优于治疗Ⅱ组和对照组（Ｐ < 0.001），治疗Ⅱ组头痛天数的降低显著优于对照组（Ｐ < 0.05）；②3组治疗前CGRP的表达无显著差异，治疗Ⅰ组、治疗Ⅱ组治疗结束4周后随访CGRP的表达较治疗前均显著下降（Ｐ < 0.001），对照组治疗结束4周后随访CGRP的表达较治疗前差异无显著性（Ｐ > 0.05）；治疗Ⅰ组CGRP治疗结束4周随访的表达较治疗Ⅱ组和对照组均显著下降（Ｐ < 0.01），治疗Ⅱ组CGRP的表达较对照组显著下降（P < 0.01）。结论 ①八脉交会穴施以“龙虎交战”针法针刺能明显改善MO患者的头痛天数，同时降低MO患者血清CGRP的表达水平，这可能是针刺八脉交会穴治疗MO的机制之一；②非经非穴点的针刺效应无持续性，而八脉交会穴的针刺效应具有持续性；③八脉交会穴可以充分发挥复式针刺手法的治疗效应，提示我们在临床上治疗疾病时不仅要注意腧穴配伍，恰当的针刺手法更是提高临床疗效、事半功倍的关键。
