Neonatal hypertension is a rare but well recognised condition, especially in newborns needing invasive monitoring in the intensive care unit. Recognition of newborns with hypertension remains challenging because of natural variability in blood pressure with postconceptional age and the lack of reference data for different gestational ages. Investigation of neonates with hypertension can be challenging in light of the myriad differing aetiologies. This may be simplified by a systematic approach to investigation. There remains a relative paucity of data to guide the use of pharmacological therapies for hypertension in neonates. Clinicians rely on empirical management protocols based on experience and expert opinion. Much of the information on dosing regimens and protocols has simply been derived from the use of antihypertensive agents in older children and in adults, despite fundamental pathophysiological differences.

AbstractThe effect of blood pressure (BP) on the incident cardiovascular events, progression to end-stage renal disease (ESRD) and mortality were evaluated among chronic kidney disease (CKD) patients with and without antihypertensive treatment. This nationwide study used the Korean National Health Insurance Service-Health Screening Cohort data. The hazards of outcomes were analysed according to the systolic BP (SBP) or diastolic BP (DBP) among adults (aged ≥ 40 years) with CKD and without previous cardiovascular disease or ESRD (n = 22,278). The SBP and DBP were ≥ 130 mmHg and ≥ 80 mmHg in 10,809 (48.52%) and 11,583 (51.99%) participants, respectively. During a median 6.2 years, 1271 cardiovascular events, 201 ESRD incidents, and 1061 deaths were noted. Individuals with SBP ≥ 130 mmHg and DBP ≥ 80 mmHg had higher hazards of hypertension-related adverse outcomes compared to the references (SBP 120–129 mmHg and DBP 70–79 mmHg). SBP < 100 mmHg was associated with hazards of all-cause death, and composite of ESRD and all-cause death during follow-up only among the antihypertensive medication users suggesting that the BP should be < 130/80 mmHg and the SBP should not be < 100 mmHg with antihypertensive agents to prevent the adverse outcome risk of insufficient and excessive antihypertensive treatment in CKD patients.

Objective. To provide reference data for ambulatory blood pressure monitoring (ABPM) and to determine the influence of age, sex, and race on these values. Methods. ABPM was performed on 300 healthy, normotensive boys and girls between the ages of 10 and 18 years, including 160 boys and 140 girls, of whom 149 were white and 151 were black. Mean systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) while awake and during sleep were calculated for black and white boys and girls aged 10 to 12 years, 13 to 15 years, and 16 to 18 years. Results. Boys compared with girls 10 to 12 years of age had higher mean (±SD) SBP (115 ± 9 vs 112 ± 9 mm Hg; P &lt; .01) and DBP (67 ± 7 vs 65 ± 5 mm Hg; P &lt; .01) while awake. Boys compared to girls 13 to 15 years of age had higher SBP while awake (116 ± 11 vs 112 ± 8 mm Hg; P &lt; .01). Boys compared with girls 16 to 18 years of age had higher SBP while awake (125 ± 12 vs 111 ± 9 mm Hg; P &lt; .01) and during sleep (116 ± 11 vs 106 ± 9 mm Hg). Comparisons within sex showed similar changes with age for boys and girls. Blacks compared with whites 13 to 15 years of age had higher SBP during sleep (109 ± 11 vs 105 ± 10 mm Hg; P &lt; .01), and blacks compared with whites 16 to 18 years of age had higher DBP during sleep (66 ± 7 vs 58 ± 6 mm Hg; P &lt; .01). Comparisons across age groups within race showed that blacks 16 to 18 years of age had higher SBP during sleep than blacks 10 to 12 years of age (109 ± 11 vs 104 ± 10 mm Hg), and higher DBP during sleep (66 ± 7 mm Hg; P &lt; .01) than blacks 10 to 12 years of age (61 ± 7 mm Hg; P &lt; .01) and 13 to 15 years of age (61 ± 8; P &lt; .01 mm Hg). The changes with age were not significant for white subjects. Conclusion. These results provide age-specific reference data for ABPM in youths. These values differ by sex (boys more than girls) and race (Blacks more than Whites).

Hypertension is the most important modifiable risk factor for primary and secondary stroke prevention. All antihypertensive drugs are effective in primary prevention: the risk reduction for stroke is 30—42%. However, not all classes of drugs have the same effects: there is some indication that angiotensin receptor blockers may be superior to other classes of antihypertensive drugs in stroke prevention. Seventy-five percent of patients who present to hospital with acute stroke have elevated blood pressure within the first 24—48 hours. Extremes of systolic blood pressure (SBP) increase the risk of death or dependency. The aim of treatment should be to achieve and maintain the SBP in the range 140—160 mmHg. However, fast and drastic blood pressure lowering can have adverse consequences. The PROGRESS trial of secondary prevention with perindopril + indapamide versus placebo + placebo showed a decrease in numbers of stroke recurrences in patients given both active antihypertensive agents, more impressive for cerebral haemorrhage.There were also indications that active treatment might decrease the development of post-stroke dementia.

AbstractIn the last several years, there has been an increasing demand for surgical facial feminization or masculinization to treat the gender dysphoric patient. However, while aesthetic ideals for facial rejuvenation are well described and taught, there is a relative paucity of literature on how to achieve a feminine or masculine morphology. It is thus becoming increasingly important for facial plastic surgeons to understand patient goals regarding facial feminization or masculinization, and to have a systematic approach for analyzing the female and male face.

Hypertension affects 80 million people in the United States. It remains poorly controlled, with only 54% of diagnosed patients treated to blood pressure targets. Hypertension management is complex in part due to the volume of antihypertensive agents, variable patient needs and responses, and inconsistent design and outcomes from clinical trials. Therefore, trustworthy clinical practice guidelines have a key role in hypertension management. The United States experienced a 10-year gap in publication of hypertension guidelines, followed by multiple guideline publications in 2013. These guidelines led to more controversy than clarity, as there was discordance among them. This review summarizes the guidelines and clinical statements influencing the current debate in order to facilitate appropriate application.

Abstract: As the main structural component of the renin-angiotensin-aldosterone system (RAAS), the juxtaglomerular complex plays a very important role in the regulation of vascular resistance. The synthesis and release of renin into the circulation occurs due to the decrease of blood pressure, loss of body fluid, and a decrease of sodium intake. Renin converts angiotensinogen into angiotensin I, which is further converted by the angiotensin converting enzyme (ACE) into angiotensin II. This angiotensin II causes vasoconstriction of blood vessels, resulting in an increase of vascular resistance and blood pressure. The ACE inhibitors and the angiotensin receptor blockers (ARBs) do not inhibit the RAAS completely since they cause an increase of renin activity. The renin blockers are more effective in inhibiting RAAS activity; therefore, these renin blockers can be applied as antihypertensive agents with fewer side effects. The RAAS activity can be inhibited by a decrease of renin synthesis in the juxtaglomerular complex by blocking the signals in the juxtaglomerular complex that stimulate renin synthesis, and by blocking the gap junctions in the juxtaglomerular complex. Keywords: juxtaglomerular complex, vascular resistance, RAAS.   Abstrak: Kompleks jukstaglomerulus sebagai komponen struktural utama sistem renin angiotensin berperan penting dalam pengaturan resistensi pembuluh darah. Sintesis dan pelepasan renin ke sirkulasi terjadi karena tekanan darah yang rendah, kehilangan cairan tubuh, dan kurangnya intake natrium. Renin akan memecah angiotensinogen menjadi angiotesin I yang kemudian secara cepat dikonversi oleh enzim pengonversi angiotensin  menjadi angiotensin II. Angiotensin II menyebabkan vasokontriksi pembuluh darah sehingga meningkatkan resistensi pembuluh darah yang pada akhirnya akan meningkatkan tekanan darah. ACEinhibitor dan ARB kurang sempurna dalam menghambat kerja SRAA oleh karena keduanya memutuskan rantai mekanisme timbal balik sehingga meningkatkan aktifitas renin. Penghambat renin lebih efektif digunakan untuk menghambat aktifitas SRAA sehingga penghambat renin dapat digunakan sebagai obat anti-hipertensi dan memiliki efek samping yang rendah. Metode penghambatan SRAA yang juga dapat dikembangkan ialah penghambatan sintesis renin dalam kompleks jukstaglomerulus dengan cara menekan sinyal-sinyal dalam kompleks jukstaglomerulus yang merangsang sintesis renin dan menghambat fungsi taut kedap yang terdapat dalam kompleks jukstaglomerulus. Kata kunci: kompleks juksta glomerulus, resistensi vaskular, SRAA.
