Overview
HIV (Human Immunodeficiency Virus) is a virus transmitted through sexual contact, shared needles, and from mother to child during childbirth or breastfeeding. It belongs to the Retroviridae family. All patients who are diagnosed with HIV should be initiated on ART as soon as possible.
HIV can also lead to complications like dementia and chronic diarrhea with weight loss (HIV wasting syndrome).
Exceptions to this include patients presenting with cryptococcal meningitis (CM) or central nervous system tuberculosis (tuberculous meningitis (TBM) or tuberculoma).

Overview
Ebola virus is one of at least 30 known viruses capable of causing viral hemorrhagic fever syndrome. The genus Ebolavirus currently is classified into 5 separate species: Sudan ebolavirus, Zaire ebolavirus, Tai Forest (Ivory Coast) ebolavirus, Reston ebolavirus, and Bundibugyo ebolavirus. The outbreak of Ebola virus disease in West Africa from 2014 to 2016, involving Zaire ebolavirus, was the largest outbreak of Ebola virus disease in history.
As of September 17, 2019, an active outbreak of Ebola virus disease in the Democratic Republic of the Congo (DRC) had resulted in 3,034 confirmed and 111 probable cases of Ebola virus disease, including 2,103 attributable deaths. An experimental vaccine has been credited with limiting the outbreak’s scope.

Predictors of post-intubation hypotension in trauma patients following prehospital emergency anaesthesia: a multi-centre observational study
Overview
Post-intubation hypotension (PIH) is common after prehospital emergency anaesthesia (PHEA) and is linked to increased mortality in trauma patients. A multi-centre retrospective study in the UK found that clinician judgment and provider intuition are the most reliable predictors of PIH, often influencing the administration of reduced doses of induction medications for high-risk patients.

Physically Active Lifestyle Attenuates Impairments on Lung Function and Mechanics in Hypertensive Older Adults
Overview Physical activity attenuates hypertension in older adults, but its impact on pulmonary function and mechanics in hypertensive older adults is unknown. The study seeks to understand whether a physically active lifestyle can improve respiratory capacity, the mechanical efficiency of the lungs, and, consequently, the quality of life of these individuals, comparing data between groups of active and sedentary hypertensive older adults.
This is a cross-sectional study. 731 older adults were evaluated, stratified into two initial groups: hypertensive older adults (HE; n = 445) and non-hypertensive older adults (NHE; n = 286). For a secondary analysis, we used the International Physical Activity Questionnaire to sub-stratify HE and NHE into four groups: physically inactive hypertensive (PIH; n = 182), active hypertensive (AH; n = 110), physically inactive non-hypertensive (PINH; n = 104), and active non-hypertensive (ANH; n = 65). Lung function was measured by spirometry, and lung mechanics were assessed by impulse oscillometry.
It was concluded that hypertension is associated with impaired lung function and mechanics in older adults, and a physically active lifestyle attenuates these dysfunctions.

Influence of Blood Flow restriction Training on the Aerobic Capacity: A systematic review and meta-analysis
Overview
Blood flow restriction training (also known as KAATSU training) uses professional equipment to apply pressure to the base of the limbs to limit the blood flow at the distal end of the limbs during exercise, thereby stimulating muscle growth and improving muscle strength with a low exercise intensity. This study aimed to conduct a meta-analysis on the effects of blood flow restriction training on aerobic capacity. Methods: A systematic review and quantitative evidence synthesis (QES) was used to examine the effects of blood flow restriction training on the aerobic capacity. In addition, the effect of high intensity exercise is achieved with only a low-intensity load under blood flow restriction training, which has the advantages of low intensity, high frequency, and fast recovery. It was founded that blood flow restriction training promoted the improvement in aerobic capacity. Blood flow restriction training, which is a low intensity exercise, significantly affected aerobic capacity. Twelve blood flow restriction training sessions a week achieved significantly better results than a frequency of two to four training sessions per week. A daily blood flow restriction training session of 6 to 30 min significantly improved aerobic capacity.

MR Imaging of Carotid Artery Atherosclerosis: Updated Evidence on High-Risk Plaque Features and Emerging Trends
Overview
MR imaging is well-established as the criterion standard for carotid artery atherosclerosis imaging. The capability of MR imaging to differentiate numerous plaque components has been demonstrated, including those features that are associated with a high risk of sudden changes, thrombosis, or embolization. The field of carotid plaque MR imaging is constantly evolving, with continued
insight into the imaging appearance and implications of various vulnerable plaque characteristics. This article will review the most up-to-date knowledge of these high-risk plaque features on MR imaging and will delve into 2 major emerging topics: the role of vulnerable plaques in cryptogenic strokes and the potential use of MR imaging to modify carotid endarterectomy treatment guidelines.

Can YouTube be used as an educational tool in lymphedema rehabilitation?
Overview Lymphedema is defined as the abnormal accumulation of interstitial fluid and fibro-adipose tissues resulting from injury, infection, or congenital abnormalities of the lymphatic system. The gold standard approach in the treatment of lymphedema is Complete Decongestive Therapy and it has many components that require practical knowledge and skills. YouTube can be a useful tool to provide these skills to healthcare professionals and patients. The aim of this study was to examine the videos about lymphedema rehabilitation on YouTube and analyse their technical features, sources, contents, educational value and reliability. The biggest obstacle for YouTube to be an excellent source of information is that it hosts large volumes of uncontrolled and low-quality data. When YouTube content related to lymphedema rehabilitation was examined, it was observed that many videos were quite insufficient and incomplete even though there were useful videos. If careful controlling measures are implemented and if medical videos aim to meet reliability and GQS criteria, YouTube can become an effective and useful source of information for lymphedema rehabilitation.

Major Adverse Cardiovascular Events Following Partial Nephrectomy
Overview
Partial nephrectomy (PN) is associated with a non-negligible risk of postoperative cardiovascular morbidity and mortality. Identification of high-risk patients may enable optimization of perioperative management and consideration of alternative approaches. The authors aim to develop a procedure-specific cardiovascular risk index for PN patients and compare its performance to the widely used revised cardiac risk index (RCRI) and AUB-HAS2 cardiovascular risk index.
The cohort was derived from the American College of Surgeons – National Surgical Quality Improvement Program (ACS-NSQIP) database. The primary outcome was the incidence of major adverse cardiovascular events (MACE), defined as 30-day postoperative incidence of myocardial infarction stroke, or mortality. A multivariate logistic regression model was constructed; performance and calibration were evaluated using an ROC analysis and the Hosmer–Lemeshow test and compared to the RCRI and the AUB-HAS2 index.
This study proposes a novel procedure-specific cardiovascular risk index. The PN-A4CH index demonstrated good predictive ability and excellent calibration using a large national database and may enable further individualization of patient care and optimization of patient selection. | 3 | | R465.00 | |

Society of Interventional Radiology Multidisciplinary Position Statement on Percutaneous Ablation of Non-small Cell Lung Cancer and Metastatic Disease to the Lungs
Overview
The purpose of this study is to state the Society of Interventional Radiology's position on the use of image-guided thermal ablation for the treatment of early-stage non-small cell lung cancer, recurrent lung cancer, and metastatic disease to the lung. A multidisciplinary writing group, with expertise in treating lung cancer, conducted a comprehensive literature search to identify studies on the topic of interest. Recommendations were drafted and graded according to the updated SIR evidence grading system. A modified Delphi technique was used to achieve consensus agreement on the recommendation statements.
A total of 63 studies, including existing systematic reviews and meta-analysis, retrospective cohort studies, and single-arm trials were identified. The expert writing group developed and agreed on 7 recommendations on the use of image-guided thermal ablation in the lung. It was concluded that SIR considers image-guided thermal ablation to be an acceptable treatment option for patients with inoperable Stage I NSCLC, those with recurrent NSCLC, as well as patients with metastatic lung disease.

Overview Hypertension is a leading risk factor for cardiovascular disease and a significant cause of morbidity and mortality. For patients who are symptomatic, however, uncontrolled elevations in blood pressure are true medical emergencies that require rapid intervention in the ED. It is therefore important to understand the disease of chronic hypertension and, perhaps more important, episodes of acute and uncontrolled elevations in blood pressure so that we, as prehospital care providers, can better stratify these patients into low- and high-risk groups that may or may not require transport to an ED for evaluation and treatment.
As we will discuss, it is reasonable to say that not every patient who presents with hypertension is at high risk of morbidity and mortality and absolutely requires evaluation and treatment at an ED. This is not to say EMTs and paramedics should talk patients out of going to EDs for evaluation. Rather, we will strive to give prehospital care providers a better understanding of the risks involved with acute hypertension so they can better work with their patients to find a solution that is safe, reasonable and responsible for everyone involved. This article discusses the topic of acute hypertension, hypertensive urgency and hypertensive emergencies in an effort to help EMS providers better understand these illnesses and help patients make the best decisions regarding their transport and care.

Bee Sting and Anaphylaxis
Overview Hymenoptera stings account for more deaths in the United States than any other envenomation. The order Hymenoptera includes Apis species, ie, bees (European, African), vespids (wasps, yellow jackets, hornets), and ants. Most deaths result from immediate hypersensitivity reactions and anaphylaxis. Severe anaphylactoid reactions occur occasionally when toxins directly stimulate mast cells. In addition to immunologic mechanisms, some injury occurs from direct toxicity. While most stings cause only minor problems, stings cause a significant number of deaths.
Target organs are the skin, vascular system, and respiratory system. Pathology is like other immunoglobulin E (IgE)–mediated allergic reactions. Anaphylaxis is a common and life-threatening consequence of Hymenoptera stings and is typically a result of sudden systemic release of mast cells and basophil mediators. Urticaria, vasodilation, bronchospasm, laryngospasm, and angioedema are prominent symptoms of the reaction. Respiratory arrest may result in refractory cases
This study aims to discuss the different stings, prognosis and emergency reactions and treatment thereto.

| | Ischemic Stroke Part 2 | Ischemic Stroke Part 2
Overview
Ischemic stroke is characterized by the sudden loss of blood circulation to an area of the brain, resulting in a corresponding loss of neurologic function. Acute ischemic stroke is caused by thrombotic or embolic occlusion of a cerebral artery and is more common than haemorrhagic stroke.
We should consider stroke in any patient presenting with acute neurologic deficit or any alteration in level of consciousness. Although symptoms can occur alone, they are more likely to occur in combination. No historical feature distinguishes ischemic from haemorrhagic stroke, although nausea, vomiting, headache, and sudden change in level of consciousness are more common in haemorrhagic strokes. In younger patients, a history of recent trauma, coagulopathies, illicit drug use (especially cocaine), migraines, or use of oral contraceptives should be elicited.
Emergent brain imaging is essential for evaluation of acute ischemic stroke. Noncontrast computed tomography (CT) scanning is the most commonly used form of neuroimaging in the acute evaluation of patients with apparent acute stroke.
Involvement of a physician with a special interest and training in stroke is ideal. Stroke care units with specially trained nursing and allied healthcare personnel have clearly been shown to improve outcomes.

Ventricular Tachycardia Part 2
Overview
Ventricular tachycardia (VT) or ventricular fibrillation (VF) is responsible for most of the sudden cardiac deaths in the United States, at an estimated rate of approximately 300,000 deaths per year. VT refers to any rhythm faster than 100 (or 120) beats/min, with three or more irregular beats in a row, arising distal to the bundle of His. The rhythm may arise from the working ventricular myocardium, the distal conduction system, or both.
Symptoms of VT are often a function of the associated heart rate, or the causal process, such as an acute myocardial infarction (MI). They may include the following bulleted items. VT may also be asymptomatic, or the symptoms may be those of the associated triggered therapy (eg, an implantable cardioverter-defibrillator [ICD] shock).
Clinically, VT may be reflected in symptoms such as syncope, palpitations, and dyspnea. It is often, but not always, associated with hemodynamic compromise, particularly if the left ventricle is impaired or the heart rate is especially fast. With some exceptions, VT is associated with increased risk of sudden death.

| | Wide Complex Tachycardia | Wide Complex Tachycardia
Overview
Correct diagnosis of wide complex tachycardia (WCTs) can be challenging. With EMS providers' ever-expanding scope of practice, it is no longer safe to label any rhythm that is wide and fast as ventricular tachycardia (VT). Though many paramedic curricula do not address advanced cardiac dysrhythmias and treatments, several EMS departments have protocols that require advanced training in 12-lead ECG interpretation and treatment of specific cardiac dysrhythmias. One must possess the proper diagnostic tools and knowledge to decide whether a WCT is VT or SVT with aberrant conduction. EMS providers should be able to differentiate VT and SVT with aberrant conduction with confidence and a high degree of certainty. In order to understand the visual differences between VT and SVT with aberrant conduction, one must first understand the basic pathophysiology behind the two dysrhythmias. The first steps are maintenance of the patient’s airway with assisted breathing if necessary, cardiac monitoring to identify the heart rhythm, monitoring of blood pressure and oximetry, and establishing intravenous access. In the emergency setting, a wide-complex tachycardia always should be considered as ventricular tachycardia unless proven otherwise, as treatment must be initiated immediately to avoid degeneration into ventricular fibrillation.

| | Unstable Angina | Unstable Angina
Overview
Unstable angina belongs to the spectrum of clinical presentations referred to collectively as acute coronary syndromes (ACSs), which also includes ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). Unstable angina is considered to be an ACS in which there is myocardial ischemia without detectable myocardial necrosis (ie, cardiac biomarkers of myocardial necrosis —such as creatine kinase MB isozyme, troponin, myoglobin—are not released into the circulation).
With unstable angina, symptoms may (1) occur at rest; (2) become more frequent, severe, or prolonged than the usual pattern of angina; (3) change from the usual pattern of angina; or (4) not respond to rest or nitro-glycerine. Symptoms of unstable angina are similar to those of myocardial infarction (MI).
The traditional term unstable angina was meant to signify the intermediate state between myocardial infarction (MI) and the more chronic state of stable angina. The old term pre-infarction angina conveys the clinical intent of intervening to attenuate the risk of MI or death. Patients with this condition have also been categorized by presentation, diagnostic test results, or course over time; these categories include new-onset angina, accelerating angina, rest angina, early postinfarct angina, and early post-revascularization angina.
This course deals with the causes and management of unstable angina.

Severe Distress – COVID 19
Overview Since the emergence of the 2019 novel coronavirus (SARS-CoV-2) infection in December 2019, the coronavirus disease 2019 (COVID-19) has rapidly spread across the globe. The clinical spectrum of patients with COVID-19 ranges from asymptomatic or mild symptoms to critical disease with a high risk of mortality. Coronavirus disease 2019 (COVID-19) is the illness associated with the novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus was initially noted during an outbreak of respiratory illness in the population of Wuhan, the capital of Hubei province, China. The first cases were seen in November 2019, with COVID-19 quickly spreading throughout the city. The World Health Organization (WHO) was notified of the outbreak on December 31, 2019. The cases continued to spread outside of the area and then across the world. COVID-19 was reported as a global health emergency by the end of January 2020. As the worldwide case numbers increased, the WHO declared on March 11, 2020, that COVID-19 had reached the pandemic stage.
The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is called coronavirus disease 2019 (COVID-19). In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic.

| | Septic Shock Part 2 | Septic Shock Part 2
Overview
Sepsis is defined as life-threatening organ dysfunction due to dysregulated host response to infection, and organ dysfunction is defined as an acute change in total Sequential Organ Failure Assessment (SOFA) score of 2 points or greater secondary to the infection cause. Septic shock occurs in a subset of patients with sepsis and comprises of an underlying circulatory and cellular/metabolic abnormality that is associated with increased mortality.
Patients with sepsis may present in a myriad of ways, and a high index of clinical suspicion is necessary to identify subtle presentations. The hallmarks of sepsis and septic shock are changes that occur at the microvascular and cellular level and may not be clearly manifested in the vital signs or clinical examination.
Patients with sepsis and septic shock require admission to the hospital. Initial treatment includes support of respiratory and circulatory function, supplemental oxygen, mechanical ventilation, and volume infusion.
In the past few decades, the discovery of endogenous mediators of the host response has led to the recognition that the clinical syndrome of sepsis is the result of excessive activation of host defence mechanisms rather than the direct effect of microorganisms. Sepsis and its sequelae represent a continuum of clinical and pathophysiologic severity.

Respiratory Distress Syndrome
Overview
Respiratory distress syndrome, also known as hyaline membrane disease, occurs almost exclusively in premature infants. The incidence and severity of respiratory distress syndrome are related inversely to the gestational age of the new-born infant.
Shortness of breath is a common complaint encountered by the EMS provider. We often hear it as part of a litany of other S/S or as a primary chief complaint. In either case SOB is never to be taken lightly and its causes should always be thoroughly investigated. My desire with this article is to give you some tips on how to streamline your treatment and formulate your thoughts as to how to proceed. In all cases the EMS team is responsible to respond to the needs of the patient. Hypoxia, regardless of the source needs to be vigorously addressed. The lungs need to be opened or cleared as determined by the physical exam. The cause of the SOB needs to be determined and addressed. Education and counselling of parents, caregivers, and families of premature infants must be undertaken as part of discharge planning. These individuals should be advised of the potential problems infants with respiratory distress syndrome may encounter during and after their nursery stay.

Overview
Preeclampsia is a disorder of widespread vascular endothelial malfunction and vasospasm that occurs after 20 weeks' gestation and can present as late as 4-6 weeks post-partum. It is clinically defined by hypertension and proteinuria, with or without pathologic edema.
Preeclampsia is defined as the presence of (1) a systolic blood pressure (SBP) greater than or equal to 140 mm Hg or a diastolic blood pressure (DBP) greater than or equal to 90 mm Hg or higher, on two occasions at least 4 hours apart in a previously normotensive patient, OR (2) an SBP greater than or equal to 160 mm Hg or a DBP greater than or equal to 110 mm Hg or higher (In this case, hypertension can be confirmed within minutes to facilitate timely antihypertensive therapy.).
In addition to the blood pressure criteria, proteinuria of greater than or equal to 0.3 grams in a 24-hour urine specimen, a protein (mg/dL)/creatinine (mg/dL) ratio of 0.3 or higher, or a urine dipstick protein of 1+ (if a quantitative measurement is unavailable) is required to diagnose preeclampsia.
Eclampsia is defined as seizures that cannot be attributable to other causes in a woman with preeclampsia. HELLP syndrome (haemolysis, elevated liver enzyme, low platelets) may complicate severe preeclampsia.
Because the clinical manifestations of preeclampsia can be heterogeneous, diagnosing preeclampsia may not be straightforward. Preeclampsia without severe features may be asymptomatic. Many cases are detected through routine prenatal screening.

Dyspnea: Pathophysiology and a clinical approach - EMT
Overview
Dyspnea is defined as a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity and may either be acute or chronic. This is a common and often distressing symptom reported by patients, and accounts for nearly half of hospital admissions.
The distinct sensations often reported by patients include effort/work of breathing, chest tightness, and air hunger (a feeling of not enough air on inspiration). Dyspnea should be assessed by the intensity of these sensations, the degree of distress involved, and its burden or impact on instrumental activities.
Dyspnea is a common and often distressing symptom and a frequent reason for general practitioner and clinic visits. Dyspnea is symptom, and its experience is subjective and varies greatly among individuals exposed to the same stimuli or with similar pathologies. This differential experience of Dyspnea among individuals emanates from interactions among multiple physiological, psychological, social, and environmental factors that induce secondary physiological and behavioural responses. The management of Dyspnea will depend on the underlying cause.

Sleep and the athlete: narrative review and 2021 expert consensus recommendations
Overview An ever-growing volume of peer-reviewed Publications speaks to the recent and rapid growth in scope and understanding of sleep for optimal athlete health and performance.
Herein, a panel of international experts review the current knowledge on sleep and the athlete, briefly covering the background, exploring continued controversies, highlighting fruitful avenues for future research and providing practical recommendations. The introduction section covers the need for sleep, including sleep architecture and the restorative benefits of sleep for the brain and body.
Pitfalls and challenges measuring athlete sleep are reviewed, and practical recommendations provided. The following section, entitled sleep and the athlete, covers the influence of sleep inadequacy and sleep extension on athletic performance. This article reviews the evidence that elite athletes are particularly susceptible to sleep inadequacy, for example, during intensified training and in those reporting symptoms of over-reaching and overtraining. The final section, entitled strategies to improve sleep, provides practical recommendations to alleviate the symptoms of jet lag, nutritional strategies to enhance sleep and a toolbox for practitioners to manage and optimise athlete sleep.

Overview
Emergency services attend patients who are having a seizure on almost a daily basis. Consequently, they should understand the disease processes related to seizures and be confident in their prehospital management. In general, with the exception of a patient in Status Epilepticus, seizure management should be relatively straight forward.
So, what is a seizure and what causes it? Basically, a seizure is any unusually excessive neuronal firing from the brain which manifests as changes in a patient’s motor/sensory control, sensory perception, behaviour and autonomic function.
At a chemical level a seizure occurs when there is a sudden biochemical imbalance between the excitatory neurotransmitters and inhibitory neurotransmitters. The primary excitatory neurotransmitter found in the human central nervous system is called N-Methyl D Aspartate (NMDA); whereas the primary inhibitory neurotransmitter is called gamma-amino butyric acid (GABA). When there is an imbalance between these chemical mediators repeated firing and excitations of the neuronal cells occur.
Depending on the area of the brain in which this occurs, the seizure will manifest as a focal seizure, sensory change, behaviour disturbance, or complete tonic and clonic muscular activity. This course addresses important aspects relating to convulsions and seizures

Overview Anaphylaxis is a life-threatening emergency that requires immediate prehospital care, but to date all treatment guidelines have been based on an in-hospital treatment. At EMS World Expo Peter Taillac, MD, detailed the process of an expert panel to research and publish an evidence-based guideline (EBG) for the recognition and treatment of anaphylaxis. The expert panel attempted to answer a series of questions about anaphylaxis assessment and treatment through literature research and review. The guideline is intended to serve as the scientific basis for future EMS anaphylaxis protocols.
Good evidence suggests that physicians under-prescribe epinephrine and that patients (or their parents) fail to use epinephrine as quickly as possible. Accordingly, at discharge, all patients should be provided an epinephrine autoinjector and should receive proper instruction on how to self-administer it in case of a subsequent episode.

Overview
The correct and timely identification of cardiac arrest is critical to ensuring (1) the appropriate dispatch of a high-priority response, (2) the provision of telephone CPR instructions, and (3) the activation of community first responders carrying automated external defibrillators (AED) (Travers et al., 2015). Rapid defibrillation is a powerful predictor of successful resuscitation following ventricular fibrillation (VF) sudden cardiac arrest (SCA). (Berg et al., 2010a)
Advanced life support (ALS) is still considered a vital link in the chain of survival for patients with out-of-hospital cardiac arrest. Despite this the quality of evidence for many ALS interventions remains poor (Callaway et al., 2015) as do the outcomes of patients, particularly those suffering unwitnessed out-of-hospital cardiac arrest were CPR and defibrillation is delayed. As part of the development of these guidelines, the core guideline panel opted to adopt the AHA resuscitation guidelines for advanced cardiac life support. It should therefore be noted that for recommendations not reviewed by the AHA in the 2015 edition, the 2010 recommendation are considered valid.

Overview
Chest pain and acute dyspnoea are among the most frequent causes of out-of-hospital emergency medical services (EMS) activation. The challenge of the pre-hospital management of chest pain, beyond rapid diagnosis, is the treatment and transfer of patients with major cardiovascular emergencies to adequate centres (Beygui et al., 2015). The required system infrastructure (i.e. local protocols and pathways of care) needs to be in place for EMS cardiovascular emergency objectives to be met. Not all recommendations below are readily implementable as local infrastructure must still be developed in South Africa. The care of ST-elevation myocardial infarction (STEMI) patients in the pre-hospital setting should be based on regional STEMI networks. Such networks include one or more hospitals and EMS organisations which have a shared protocol for the choice of reperfusion strategy, adjunctive therapy and patient transfer in order to provide consistent treatment to patients. Such protocols should be formally discussed between all components of the network and be available in writing (Beygui et al., 2015). Acknowledgement

Overview Type 2 diabetes mellitus consists of an array of dysfunctions characterized by hyperglycemia and resulting from the combination of resistance to insulin action, inadequate insulin secretion, and excessive or inappropriate glucagon secretion. Poorly controlled type 2 diabetes is associated with an array of microvascular, macrovascular, and neuropathic complications.
Microvascular complications of diabetes include retinal, renal, and possibly neuropathic disease. Macrovascular complications include coronary artery and peripheral vascular disease. Diabetic neuropathy affects autonomic and peripheral nerves.
This course focuses on the diagnosis and treatment of type 2 diabetes and its acute and chronic complications, other than those directly associated with hypoglycemia and severe metabolic disturbances, such as hyperosmolar hyperglycemic state (HHS) and diabetic ketoacidosis (DKA).
