An overview of hypertension and cardiac involvement in Asia: Focus on heart failure

Cardiovascular Disease (CVD) is the leading cause of deaths worldwide, contributing to about 30% of all deaths. Half of the cases of CVD are estimated in Asia, the world's most populous continent. Hypertension, a major modifiable risk factor for CVD, results in more deaths than any other CV risk factors in the Asian regions. The total number of patients with hypertension is likely to grow as the population ages. The proportion of the elderly population aged 65 years or more in Asia is expected to increase from 7.4% in 2015 to 10.9% in 2030. It is important to note that more than half (54%) of the world's population live in Asia. Aside of being the biggest single risk factor for global deaths, hypertension is also an important precursor and most common risk factor of heart failure (HF). An increase in HF prevalence is clearly related to the rapid epidemiological transition caused by changes in lifestyle in Asian countries. However, the availability of data on HF burden and health care delivery is limited in Asia compared with Europe and North America. This reality has driven the working group of Asian experts for example the HOPE Asia Network to concentrate on hypertension as risk factors for CVD, with the mission to improve the management of hypertension resulting in organ protection toward a goal of achieving “ZERO” CV event in Asia. This paper aims to give an overview regarding the heart problems caused by hypertension in Asia, focus on HF.     

Current status of ambulatory blood pressure monitoring in Asian countries: A report from the HOPE Asia Network

Ambulatory blood pressure monitoring (ABPM) can measure 24‐hour blood pressure (BP), including nocturnal BP and diurnal variations. This feature of ABPM could be of value in Asian populations for preventing cardiovascular events. However, no study has yet investigated regarding the use of ABPM in actual clinical settings in Asian countries/regions. In this study, 11 experts from 11 countries/regions were asked to answer questionnaires regarding the use of ABPM. We found that its use was very limited in primary care settings and almost exclusively available in referral settings. The indications of ABPM in actual clinical settings were largely similar to those of home BP monitoring (HBPM), that is, diagnosis of white‐coat or masked hypertension and more accurate BP measurement for borderline clinic BP. Other interesting indications, such as nighttime BP patterns, including non‐dipper BP, morning BP surge, and BP variability, were hardly adopted in daily clinical practice. The use of ABPM as treatment guidance for detecting treated but uncontrolled hypertension in the Asian countries/regions didn't seem to be common. The barrier to the use of ABPM was primarily its availability; in referral centers, patient reluctance owing to discomfort or sleep disturbance was the most frequent barrier. ABPM use was significantly more economical when it was reimbursed by public insurance. To facilitate ABPM use, more simplified indications and protocols to minimize discomfort should be sought. For the time being, HBPM could be a reasonable alternative.     

Diversity of and initiatives for hypertension management in Asia—Why we need the HOPE Asia Network

The Hypertension Cardiovascular Outcome Prevention and Evidence in Asia (HOPE Asia) Network was set up to improve the management of hypertension in Asia with the ultimate goal of achieving “zero” cardiovascular events. Asia is a diverse continent, and the prevalence of hypertension has increased over the last 30 years. There are a number of Asia‐specific features of hypertension and hypertension‐related cardiovascular complications, which means that a region‐specific approach is needed. White‐coat hypertension will become more of an issue over time as Asian populations age, and masked hypertension is more prevalent in Asian than in Western countries. Identifying and treating masked hypertension is important to reduce cardiovascular risk. Abnormal patterns of blood pressure (BP) variability common in Asia include exaggerated early morning BP surge and nocturnal hypertension. These are also important cardiovascular risk factors that need to be managed. Home blood pressure monitoring (HBPM) is an important tool for detecting white‐coat and masked hypertension, and monitoring BP variability, and practices in Asia are variable. Use of HBPM is important given the Asia‐specific features of hypertension, and strategies are needed to improve and standardize HBPM usage. Development of HBPM devices capable of measuring nocturnal BP along with other information and communication technology‐based strategies are key developments in the widespread implementation of anticipation medicine strategies to detect and prevent cardiovascular events in patients with hypertension. Region‐wide differences in hypertension prevalence, control, and management practices in Asia highlight the importance of information sharing to facilitate best practices.     

Effect of epidural analgesia on change in Mallampati class during labour

Mallampati class has been shown to increase during labour. Epidural analgesia might influence this change. The aim of our study was to compare the change in Mallampati class during labour in parturients who did and did not receive epidural analgesia and study the association of these changes with pre‐defined clinical characteristics. We performed a prospective observational study of 190 parturients. Using standard methodology, photographs of the upper airway were taken with a digital camera during early labour and within 90 min of delivery. Two to three consultant anaesthetists, blinded to the origin of the photographs, evaluated the images obtained and assigned a Mallampati class to each. Overall, Mallampati class increased in 61 (32.1%), decreased in 18 (9.5%) and did not change in 111 (58.4%) parturients (p < 0.001). The proportions of parturients in the epidural and non‐epidural groups who demonstrated an increase, decrease and no change in Mallampati class were similar. Of the relationships between change in Mallampati class and the other factors studied, only the total dose of epidural levobupivacaine during labour demonstrated a weak positive correlation 0.17 (p = 0.039) with Mallampati class. This study confirms that labour is associated with an increase in the Mallampati class in approximately one third of parturients. Our findings indicate that having an epidural does not influence the likelihood of a change in Mallampati class during labour.     

Ophthalmic manifestations in the COVID-19 clinical spectrum

Purpose:The aim of this study was to determine the frequency and various types of ophthalmic manifestation of patients with COVID-19.Methods:This is a prospective observational study conducted on patients with SARS-Co-V-2 infection, at a dedicated tertiary COVID-19 hospital in South India from April 1 to July 31, 2020. At the time of their admission to the COVID hospital, demographic data such as name, age, sex was recorded. A thorough history regarding the onset, duration, progression, nature of symptoms and its associated factors, medication history, treatment history were elicited and documented. Ocular examination was performed under torchlight by an ophthalmologist posted for COVID duty. Further investigations including imaging were sought for, depending on clinical indications. Serial follow-up examinations of all patients were carried out every 72 hours or when patients complained of any ocular symptoms whichever earlier, until discharge. All relevant data were compiled and statistically analyzed.Results:A total of 2742 patients were examined. Of them, 1461 (53.28%) were males and 1281 (46.72%) were females. The mean age (±SD) was 39.46 ± 17.63 years. None of the patients in our study had any ocular symptoms or signs as the presenting complaint at the time of their admission. On subsequent follow-up, only 20 (0.72%) developed ocular manifestations, of which 19 (95%) had features suggestive of Bilateral viral conjunctivitis. However, 1 (5%) patient had orbital cellulitis secondary to pansinusitis.Conclusion:Ophthalmic manifestations in the clinical spectrum of COVID-19 infection are uncommon and unlikely to be the presenting clinical impression. However, it has broadened our view to a wider spectrum of COVID-19 presentations enhancing our clinical acumen for staunch detection of COVID-19 suspects in our daily practice, augmenting early diagnosis and management and also break the chain of transmission for the greater good of humanity.     

The First 100 Consecutive,Robot-assisted,Intracorporeal Ileal Conduits: Evolution of Technique and 90-day Outcomes

Background

Robot-assisted radical cystectomy (RARC) has evolved over the last few years to become an acceptable alternative option to open radical cystectomy. Most series of RARC used an open approach to urinary diversion. Even though robot-assisted intracorporeal urinary diversion (RICUD) is the natural extension of RARC, few centers have reported their experiences with RICUD in general, and in particular, of robot-assisted intracorporeal ileal conduits (RICIC).

Objective

To report our experience with RICIC using the Marionette technique.

Design, setting, and participants

The first 100 consecutive patients who underwent RARC and RICIC, and had ≥3 mo of postoperative follow-up were included in this study. Patients were divided into four groups of 25 patients each to study the evolution of our surgical technique.

Intervention

RICIC.

Outcome measurements and statistical analysis

Intraoperative, pathologic, and 90-d postoperative outcomes for the four groups and the overall cohort were compared using the Fisher exact test (categorical variables) and the Kruskal-Wallis test (continuous variables). Continuous variables were reported as median (range) and categorical variables were specified as frequency (percentage).

Results and limitations

Overall operative and specific diversion times were 352 and 123 min, respectively. Estimated blood loss was 300 ml, lymph node yield was 24, and positive surgical margin rate was 4%. Length of hospital stay increased from 7 d for group 1 to 9 d for group 4. The overall 90-d complication rate was 81%; 19% of complications were high grade. Infections were the most common complications, representing 31% of all complications. There were no statistically significant intergroup differences except in diversion time, intraoperative transfusions, and length of stay.

Conclusions

RICIC diversion is safe, feasible, and reproducible. Larger series with longer follow-up are needed to validate the procedure and define its place in the minimally invasive urologic armamentarium. Quality of life studies need to be conducted to compare benefits of intracorporeal urinary diversion.
