Night owls (late chronotypes)

 Night owls (late chronotypes)

Night owls, yaani jo log late raat tak jaagte hain (inko late chronotypes kehte hain), unmein type 2 diabetes (T2D) ka risk zyada ho sakta hai, aur ye risk unhealthy lifestyle se bhi zyada ho sakta hai. European Association for the Study of Diabetes (EASD) 2024 Annual Meeting ek research mein kehta hai ki late-night sleepers ko early risers ke comparison mein lagbhag 50% zyada chances hote hain T2D develop karne ke.

Dr. Jeroen van der Velde, Leiden University Medical Center, Netherlands se, jo is study ko lead kar rahe the, unhone bataya, "Ye risk jitna humne expect kiya tha, usse zyada tha, lekin kuch aur factors bhi ho sakte hain jo is result ko influence karte hain."

Pehle ki studies mein late chronotypes ko poor lifestyle habits, obesity, aur heart se judi bimariyon se link kiya gaya tha. Is study ne confirm kiya ki night owls ka waist size bada hota hai aur unmein zyada visceral fat hota hai. Lekin Dr. van der Velde ne kaha ki lifestyle akela ye explain nahi karta ki late chronotype aur metabolic disorders ke beech kya connection hai.

Pehle studies bas BMI (body mass index) pe focus karti thi, lekin BMI se fat distribution ka pura idea nahi milta. Do log jo same BMI ke ho, unka fat body mein alag-alag tarah se distribute ho sakta hai, aur ye metabolic risk ke liye zyada important ho sakta hai.

Researchers ne Netherlands Epidemiology of Obesity study ke data ko analyze kiya, jisme unhone chronotype, BMI, waist size, visceral fat, liver fat, aur T2D risk ke beech ka relationship dekha. Is study mein 5000 se zyada middle-aged log shamil the, jinka average age 56 saal tha. Inmein se 54% auratein thi aur average BMI 30 tha. Chronotype ko sleep ke midpoint ke basis pe divide kiya gaya aur participants ko 3 groups mein baanta gaya: early, intermediate, aur late sleepers. Visceral aur liver fat ko MRI scans aur spectroscopy ke through measure kiya gaya.

6.6 saal ke follow-up ke baad, 225 logon mein T2D diagnose hua. Lifestyle factors jaise diet, physical activity, aur sleep quality ko adjust karne ke baad bhi, late chronotypes mein T2D ka 46% zyada risk tha. Unka BMI zyada tha, waist size bada tha,  visceral aur liver fat bhi unmein zyada tha.

Researchers ka maanna hai ki night owls ka body clock misaligned hota hai, jo metabolic problems aur T2D ka risk badha sakta hai. Dr. van der Velde ne explain kiya ki night owls ka circadian rhythm society ke schedules se match nahi karta, jo metabolic disturbances create karta hai.

Chronotype pehle 30 saalon tak badalta hai, aur uske baad stable ho jata hai. Dr. van der Velde ne suggest kiya ki agar 30 saal ki age tak aap earlier sleep pattern apna lete hain, to later life mein aapka chronotype healthy reh sakta hai. Lekin is study mein is baat ko directly address nahi kiya gaya.

Dr. Gianluca Iacobellis, jo University of Miami Hospital Diabetes Service ke director hain, unhone bataya ki circadian rhythms disrupt hone se hormone systems pe asar padta hai, jo insulin sensitivity aur glucose control ko regulate karte hain, aur diabetes ka risk badh jata hai. Night owls zyada raat ko khana khate hain, jo weight gain aur obesity ko badhata hai, aur diabetes ka risk aur zyada ho jata hai.

 

Iacobellis ne ye bhi kaha ki vital exhaustion, jo extreme fatigue se hoti hai, cardiovascular risk aur visceral fat ke markers se judi hoti hai, jo night owls ke metabolic risk ko aur badha sakti hai. Unhone logon, especially teenagers aur high-risk individuals ko educate karne ki importance pe zor diya, taaki healthy sleep habits promote ki ja sake aur in risks se bacha ja sake.

Chronic neck pain

  Chronic Neck Pain: A Primary Care Approach Neck pain bahut hi common hai, aur ise hum teen main types mein divide karte hain: 1. Mechanical Neck Pain Ye sabse zyada commonly dekhi jaane wali neck pain hai jo primary care centre mein aati hai. Patients ko generally localized neck pain hota hai jo kisi aur jagah radiate nahi karta. Zyada tar ye pain neck ke center mein hota hai. Symptoms: Localized pain jo neurological deficits ke bina hota hai, jaise weakness ya numbness nahi hoti. Agar aap us jagah ko press karte ho jaha "ouch" feel hota hai, toh wohi area problematic hota hai. Etiology: Exact cause clear nahi hota, lekin myofascial ya musculoskeletal strain se related hota hai. Management: Ye pain time ke sath apne aap theek ho jaata hai, chahe aap koi intervention karein ya na karein. Common treatments mein NSAIDs (painkillers), physical therapy, aur massage include hain. Physical therapy helpful ho sakti hai taaki patient apni posture aur movement ko sudha

GENE THERAPY SE DIKHAYI DENE LAGI BEHTAR VISION CONGENITAL BLINDNESS MEIN

  GENE THERAPY SE DIKHAYI DENE LAGI BEHTAR VISION CONGENITAL BLINDNESS MEIN   Ek naye gene therapy, ATSN-101, ne rare congenital blindness ke ek type, Leber congenital amaurosis (LCA) 1, se peedit bade aur bacchon mein roshni ko mehsoos karne aur vision ko behtar banane ke promising results dikhaye hain. Ye LCA, GUCY2D gene mein mutation ke kaaran hoti hai. “The Lancet”mein chhapi ek early-phase clinical trial mein 15 patients ko shaamil kiya gaya aur roshni ko mehsoos karne mein khaas sudhar dekha gaya. Is trial ke dauran, 12 mahine ke ilaj ke baad, jinhonne therapy ka sabse highest dose liya unmein nazar ke bareek tafseel (fine details) dekhne ki kshamata mein sudhar dikha. Example ke taur par, patients ne eye test chart par lagbhag 8 letters behtar dekhe, jo ETDRS chart ke lagbhag 2 lines ke barabar hai. Halanki nazar ki tez kshamata (acuity) mein sudhar chhote the, lekin roshni ko mehsoos karne ki kshamata, khaaskar retine ke rods aur cones mein, sabse khaas baat thi. Dr. A

Sweet syndrome (Introduction, Types, Pathophysiology)

  Acute Febrile Neutrophilic Dermatosis (Sweet Syndrome) Introduction Sweet Syndrome (SS), ya acute febrile neutrophilic dermatosis, ko pehli baar Robert Douglas Sweet ne 1964 mein describe kiya tha. Ye ek reactive process hai jo achanak se tender, red-to-purple papules aur nodules ke saath hota hai, jo aksar plaques banate hain. Ye lesions zyadatar upper extremities, face, ya neck par hote hain. Is dermatologic condition ke saath fever aur elevated neutrophil levels (peripheral neutrophilia) bhi dekhe jaate hain. Sweet syndrome ko teen types mein categorize kiya gaya hai based on underlying cause: 1. Classic ya Idiopathic Sweet Syndrome Ye sabse common form hai, jo predominantly young women ko affect karta hai aur aksar mild respiratory illness ke baad hota hai. Iska association pregnancy, inflammatory bowel disease (IBD), vaccinations, inflammatory conditions, aur infections se bhi ho sakta hai. 2. Malignancy-Associated Sweet Syndrome   Ye form underlying malignancy ke
