World Brain Health Day: Stroke management and head injury care to be provided on a ‘hub-and- spoke' model in Karnataka
Under this model, an advanced stroke and head injury centre (hub) at NIMHANS will coordinate for establishment of spoke centres in six medical colleges and provide guidance and support across the State. July 22 is observed as World Brain Day and the theme for 2025 is 'Brain Health for All Ages.'
A stroke occurs when the blood supply to part of the brain is disrupted, either by a blockage or a bleed, causing brain cells to die due to lack of oxygen and nutrients. This can lead to a range of disabilities, from mild weakness to severe paralysis, and in some cases, permanent disability and even death.
Golden hour
Recognising the symptoms and seeking immediate medical attention within the 'golden hour' - four to six hours after symptoms begin - is crucial for minimising damage and maximising recovery. Immediate treatment can significantly improve outcomes by restoring blood flow to the brain and preventing further cell death, doctors said.
The stroke management and head injury care project will be on the lines of Karnataka's heart attack (ST-Elevation Myocardial Infarction - STEMI) management project currently running in 86 taluks. The hub-and-spoke model will avoid delay in providing stroke diagnosis and treatment apart from head injury care to needy patients. Accessibility to timely care closer to their place of stay will avoid patients rushing to NIMHANS, thereby ensuring there is no congestion at the premier mental health institution. At NIMHANS six to 12 stroke patients and 15 to 16 head injury cases are seen daily.
NIMHANS apex centre
Girish B. Kulkarni, Professor of Neurology and head of the stroke unit at NIMHANS, told The Hindu on Monday that the hub-and-spoke model for stroke management, involves a network of healthcare facilities where NIMHANS - the apex stroke centre (hub) will provide advanced care and support to surrounding smaller facilities (spokes). 'This model aims to improve stroke outcomes by streamlining access to timely and appropriate care, especially in the crucial 'golden hour' after a stroke,' Dr. Girish said.
While the apex centre at NIMHANS started three months ago, a spoke centre at the Karnataka Medical College and Research Institute (KMCRI) in Hubballi has started tracing stroke patients and has been providing routine stroke management recently.
With funding from the State government, KMCRI is all set to get a Digital Subtraction Angiography (DSA) machine shortly. This equipment is used in stroke management to visualise blood vessels in the brain and identify blockages or abnormalities that may be causing a stroke, the doctor said.
Apart from KMCRI, spoke centres will be established in government medical colleges in Bengaluru (Bangalore Medical College and Research Institute), Mysuru Medical, Raichur and Ballari. 'We have identified the colleges and the centres will be established soon at a total cost of ₹56 crore,' Dr. Girish said.
Brain health
Karnataka's Brain Health Initiative (KaBHI) being run in collaboration with NIMHANS has helped improve early detection and management of neurological disorders at the grassroots level. The initiative has trained primary healthcare providers — including doctors and nurses — to identify and treat common neurological conditions such as stroke, epilepsy, and headache in district and taluk hospitals. This has already brought neurological care closer to the people, especially in rural and semi-urban areas, and reduced delays in diagnosis and treatment.

Sharing his views on 'The Evolution of Infertility Treatment', Gopinath, Director, Reproductive Medicine, Kauvery Hospital, Vadapalani, said: 'It affects one in six couples and the selection of patient with proper indication is crucial.' He spoke about how and why 3-parenting baby is picking up, under which the cytoplasm from donor eggs is transferred to the mother's oocyte and fertilised by the father. 'It is helpful in mitochondrial dysfunctions,' he said, and highlighted fertility preservation done in unmarried women or women who want to postpone childbirth and in those diagnosed with cancer in reproductive age group. K. Shanmugavadivu Venkatesan, Senior Obstetrician and Gynaec Endoscopic Surgeon, and Reproductive Medicine Consultant, Kauvery Hospital, Salem, spoke on 'Subfertility in Women' to remind that it is not the inability to conceive but but a delay due to reduced ability'. Women with ovulation disorders, PCOS, abnormalities in shape and size of uterus have the possibility of conceiving with medical intervention, she added. S. Divya, Consultant, Fertility Specialist, Obstetrician and Gynaecologist, explained in detail how the procedure of IVF is carried out which has an average success rate of 30% to 40% depending on the patient's profile. Ramya Praveen Chander, Consultant, Reproductive Medicine and IVF Specialist, Kauvery Hospital, Radial Road, said: 'Women with unexplained infertility and mild endometriosis and men with sexual dysfunction and retrograde ejaculation require Intra Uterine Insemination (IUI). According to her around 80% pregnancies occur in first three IUI cycles and younger women in their 20s have higher success rate. Beyond that, advanced treatment like IVF is needed, she said delineating the risks and benefits of IUI. Watch the webinar here:

Open-heart surgeries halted at KGH since January due to defunct equipment
Open heart surgeries have been suspended at King George Hospital (KGH) in Visakhapatnam since January this year owing to defunct equipment, causing hardship to patients, especially those belonging to economically weaker sections who cannot afford treatment at corporate hospitals. The KGH officials admitted that except the open heart surgeries, all other cardiac surgeries are being performed. Open heart surgeries are not being performed due to non-functioning of two major medical equipment– Heart Lung Machine (HLM) and Temperature Monitoring Machine (TMM). The HLM, also known as the Cardiopulmonary Bypass Machine, temporarily takes over the functions of the heart and lungs during open-heart procedure. It allows surgeons to operate on a failing heart by circulating blood and providing oxygen while the patient's heart and lungs are bypassed. Without this machine, it is not possible to perform an open heart surgery. The TMM plays a vital role in assessing and managing the overall health of a patient, especially during surgeries or critical care situations. Although surgeries have been suspended since January, the issue has recently come to light with reports and allegations by the patients. This is the second such situation after 2015, when the KGH did not perform open heart surgeries for some time due to the absence of a cardiothoracic surgeon. There was a proposal to allow corporate hospitals to use KGH facilities for open heart surgeries, but it was withdrawn due to strong opposition from the people. The surgeries resumed after two years with the coronary artery bypass graft surgery performed on a patient from Odisha. 'The heart-lung machine stopped working some time ago. We issued orders two days ago to hire the machine on a rental basis. The new HLM will be purchased through ICICI Bank's Corporate Social Responsibility support. Other cardiac surgeries are being performed without any issues,' Visakhapatnam Collector and KGH Hospital Committee Chairman M.N. Harendhira Prasad told The Hindu on Wednesday. KGH Superintendent Dr. I. Vani said that they had ordered HLM and TMM machines on a lease basis from a company in Hyderabad. 'The equipment will be available at the KGH soon. We are also taking all steps to procure the equipment needed for open heart surgery through MPLADS and CSR funds. The cost of these is around ₹3 crore. Open heart surgery has been stopped since January this year. Once the equipment reaches us, we will resume it soon. At least 15 to 20 open heart surgeries can be done in a month at KGH,' Dr. Vani said.

Body of Kodagu man being brought back from Guyana
Madikeri: Mortal remains of a resident of Kodagu, who died in Guyana, will be brought back to India, the Non-Resident Indian Forum said on Wednesday. The state govt will extend financial assistance to bring back the body of PB Girish Babu Pale, who is a native of Madenadu village in Madikeri taluk, it stated. Girish was working as a staff nurse in the Sheriff General Hospital in Guyana, South America, for about two years. On July 3, he was admitted to the hospital where he was working due to illness and was undergoing treatment. However, he died of a heart attack on July 14. Following the incident, the family was in constant touch with the hospital and the Indian Embassy to bring the mortal remains to India. The embassy informed that the family of the deceased would have to pay about Rs 12 lakhs to bring the mortal remains to India. Janaki, wife of Girish, appealed to the Non-Resident Indian Forum for assistance from the govt, stating that the family was financially backward. Accordingly, the forum requested chief minister Siddaramaiah to consider the request. Janaki also met the CM and sought his intervention. In response, the state govt sanctioned Rs 3.6 lakh while the remaining amount is being borne by the Sheriff General Hospital where Girish worked, the Forum stated on Wednesday. In addition, the alumni of Basavanahalli Morarji Desai Residential School, where Girish studied, approached Virajpet MLA AS Ponnanna and requested him to provide financial assistance. The Indian Embassy in Guyana and the resident commissioner in New Delhi are coordinating the bringing of the body to India.
