Brief Summary: To examine the effect of two different transfusion regimens on rehabilitation after hip fracture surgery.


Options:
A: Inclusion Criteria:

* Primary hip fracture
* capable of informed consent
* independently dwelling
* able to ambulate independent of human assistance
* no active heart condition defined as no AMI within 3 months, no unstable angina or present incompensation/pulmonary oedema
* no regular transfusion demand or terminal disease.

Exclusion Criteria:

* patient refusal to participate in relevant rehabilitation
* reoperation within 4. postoperative day.
B: Inclusion Criteria:

1. Age ≥18 years old at time of presentation
2. First ever episode aneurysmal SAH
3. Confirmed aneurysmal SAH diagnosis: as confirmed by treating Neurosurgeon or Neuro-interventionalist and supported by blood in subarachnoid space (demonstrated on cranial imaging or cerebrospinal fluid positive for xanthochromia) that is the result of a ruptured saccular aneurysm (confirmed by cranial imaging - cranial topography or magnetic resonance imaging angiography or catheter angiogram)
4. Incident hemoglobin ≤100g/L within 14 days following SAH (defined by first day of hospital presentation)

Exclusion Criteria:

1. Physician and or family decision to withdraw/withhold critical care at time of enrolment
2. Active bleeding with hemodynamic instability at time of enrolment
3. Patients with contra-indication or known objection to blood transfusions
4. SAH due to causes other than saccular aneurysm rupture including mycotic, traumatic and dissecting aneurysms, and aneurysms associated with arteriovenous malformations.
C: Inclusion Criteria:

* 18 years of age or older
* Either ST segment elevation myocardial infarction or Non ST segment elevation myocardial infarction consistent with the 3rd Universal Definition of Myocardial Infarction criteria that occurs on admission or during the index hospitalization
* Hemoglobin concentration less than 10 g/dL at the time of random allocation
* Patient physician believes that both of the transfusion strategies are consistent with good medical care for the patient

Exclusion Criteria:

* Uncontrolled acute bleeding at the time of randomization defined as the need for uncrossed or non-type specific blood
* Decline blood transfusion
* Scheduled for cardiac surgery during the current admission
* Receiving only palliative treatment
* Known that follow-up will not be possible at 30 days
* Previously participated in MINT

* Patient physician does not believe the patient is an appropriate candidate for the trial
D: Inclusion Criteria:

* Acute leukemia patients (AML, ALL, APL, treatment-related myeloid neoplasm, high grade MDS)
* Admitted with plans for inpatient myelosuppressive chemotherapy (with standard of care or protocol regimens)

Exclusion Criteria:
