The document discusses cardiovascular pathophysiology, focusing on diseases of the arteries, veins, heart, and heart failure. Key points include:
- Arteriosclerosis and atherosclerosis involve thickening and hardening of arterial walls due to accumulation of macrophages and lipid. This can progress from fatty streaks to fibrous plaques.
- Hypertension, which can be primary or secondary, increases blood pressure and risks complications like left ventricular hypertrophy, coronary artery disease, and stroke. Treatment involves lifestyle changes and medications.
- Other arterial conditions discussed include aneurysms, thrombus formation, embolism, and peripheral artery disease. Venous diseases covered are varicose veins, deep vein thrombosis, and
Cardiovascular disease is the leading cause of death in the US. Risk factors include obesity, physical inactivity, high blood pressure, and high cholesterol. Obesity rates have risen significantly over the past few decades, particularly abdominal or visceral obesity which is linked to heart disease. Physical activity levels have also declined such that inactivity now poses a major risk factor for cardiovascular problems. Maintaining a physically active lifestyle and managing weight are important ways to reduce cardiovascular risks and promote longevity.
Diabetes occurs when there is inadequate insulin production or absorption into cells. Insulin is needed to metabolize glucose for energy at a cellular level. Lack of glucose metabolism leads to alternative metabolism of fat and protein, causing symptoms like frequent urination, thirst, and hunger. Chronic high blood glucose can damage organs over time. The goal is glycemic control to prevent complications through lifestyle changes, medication, and monitoring blood sugar levels.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Which means 5% is due to: renal (renal artery stenosis) and hyperaldosteronism. \n
AWESOME!!\n
Pheochromocytoma - very rare. Causes head aches and sweating. \nRenal vascular disease - triggar RAA system. \n
“lower the pressure, the better, as long as it is not symptomatic”.\n
ALWAYS start with life style modification. \nIf not at goal, then look at drugs. \nBeta blockers and diaretics as long as they are not opposed to them.\nIf diabetic, then use ACE inhibitors.\nSometimes ACEi don’t work as well as Ca channel blockers in AA.\n
acute corronary syndrom, Marfan’s with aneurism, AAA, worry about dissection through vessel wall. \n
Pain secondary to ischemia. \nUsually seen in youn men who smoke cigarrettes. \nTx - sessations, vasodilators\n
\n
May be due to decreased release of vasodilation chemicals. \nImmune complex, type III\nTips of fingers, top of phylanges. Can happen more with stress. \nWhite, blue, then red. \n\n
Can become painful and lower extremity edema. Can cause hyperpigmentation and ulceration due to venus stasis. \n
\n
Number one Killer in us Men and Women.\n\n
\n
Silent MI - diabete. Based on secondary neuropathy. No sensation of chest pain. \nWomen present with atypical presentations: tierd, vague abdominal pain, be sensitive.\nVessels decrease by 50% before symptoms. \nStart with exercise induced pain. \n
Some women will just have back pain. \nEcho’s and stress tests\nACE Inhib - actually prevents remodelling that predispose heart to “floppy sloppy”.\n\n
\n
Q-wave - with full-thickness (transmurral).\nBlood must be blocked for 20 minutes or more. \nDysrhythmia is the most common complication resulting from an MI. \nThen remodeling, then heart failure. \n
Myosite might be stunned for a couple days. \n
\n
Inflammation makes exudate. \nIf infectious, then cells like PMN’s will come in. \nTampanad - enough fluid to cause contraction on heart. \nFever, Chest pain that increases when lying down!!! Slight ST segment elevation with no Q. --> acute pericarditis. \n
\n
SUDDEN DEATH - \n
Dilated: viral, pregnancy, drugs and etoh.\nHypertrophic: valve regurg, fatigue, dry cough at night, \nRestrictive: least common. \n\nTx - diuretics, ACEi, \n
If it occurs during diastole, it is most likely a pathologic murmur.\n
Egophany - A to E changes. Sign of consolidation. \n
Balooning at leaflett’s. \nLate systolic murmer is a back-flow murmur. \n
Usually staph, need anti bact with dental.\nLess rheumatic, more drug use.\nUnexplaned feaver and new murmur. MOST IMPORTANT signs. \nCould become emboli, bacteremic, autoimmune predisposition. \n
Takes a long time for IV-antibiotics \n
RIght sidded - due to lung disease, core pulmonaly,\nIf bad enough, can lead to left sided. \nLeft sided - due to systemic HTN, Mitral stenosis, \n
